Omega-3 fatty acids are important for brain health (Barnes et al., 2021; Lange, 2020; Thomas et al., 2021). Nuts—particularly walnuts—are high in omega-3 fatty acids (The Nutrition Source, n.d.). After covering experimental design or as a experimental design booster in the lifespan chapter, give students this hypothesis, and then ask them to work in small groups to design an experiment that would test it. Hypothesis: Eating walnuts will enhance the neuropsychological and behavioral development of adolescents. Ask the groups to identify the independent variable—both experimental and control conditions—and the dependent variables. Students should also provide operational definitions of all variables. Before deciding on operational definitions, encourage students to consider what information they may be lacking. For example, has previous research revealed how many grams of walnuts a day may be needed? How many days or weeks may the walnuts need to be eaten to see any effects? What kinds of dependent measures might reveal effects? This is a good opportunity to explain the importance of a lit review. Knowing what other researchers have done and have discovered can inform how we design our study. After groups have had an opportunity to design their studies, invite a representative from each group to share their design. As an out-of-class assignment, ask students to read this freely available Lancet article on an experiment conducted in a dozen high schools in Barcelona (Pinar-Martí et al., 2023) and to answer these questions: What was the independent variable? Identify both the experimental and control conditions. What was the operational definition used for the experimental condition? What were the dependent variables? Hint: there were four neuropsychological variables and two behavioral variables. When the researchers removed from their data analysis those in the experimental group who did not eat the amount of walnuts as requested, what results did they find?   References Barnes, S., Chowdhury, S., Gatto, N.

Eating fruits and vegetables is good for all of us, including growing children. Researchers wondered what caregivers could do to increase fruit and veggie intake among the younger set. Explain to your Intro Psych students that the first thing researchers do is a literature review where we dive into the research databases to find peer-reviewed journal articles on our topic of interest. If you’d like your students to get practice using your library’s databases, contact your favorite reference librarian for database instructions you can provide your students. Ask students what search terms might yield the best results for this topic. I had success using just ‘vegetables’ and ‘children.’ Explain that researchers first read the article title. If the title sounds relevant to their topic, they’ll read the abstract. If the abstract sounds promising, they’ll read the article—or, rather, they’ll read the parts of the article of greatest interest and not necessarily in order. For example, after the abstract, they may read the discussion, and then go back to the beginning to skim the introduction paying closer attention to the last paragraphs since that’s where the hypotheses are most likely to be, and then carefully read the methods section to learn how the study was done, and, then, finally, read the results. Give students a few minutes to pop into your library’s databases to search for peer-reviewed articles that identify variables that are associated with children eating more vegetables. The studies may be correlational or experimental. When they find a strategy, ask them to share it. If you’d like to skip this lit review part, instead share with your students these variables that are associated with children eating more fruits or vegetables: repeatedly giving children a taste of a vegetable (Lakkakula et al., 2010; Wardle et al., 2003), caregivers eating more vegetables (Rasmussen et al., 2006), more shared family meals (Rasmussen et al., 2006), decreased amount of television watching (Rasmussen et al., 2006), decreased incidence of eating fast food (Rasmussen et al., 2006), increased variety of fruits and vegetables available at meals (Just et al., 2012; Roe et al., 2013). Give students this hypothesis posited by one group of researchers: “children eat more fruits and more vegetables when the regular family mealtime duration is extended” (Dallacker et al., 2023). Ask students to work in small groups to design a study that would test this hypothesis. Students should identify their independent variable—including its conditions and operational definitions for those conditions—and their dependent variable(s)—including operational definition(s). Invite groups to share their experimental designs. Highlight the strengths of each group’s design while also discussing possible shortcomings. Emphasize that there is no one right way to design an experiment. The more ways a hypothesis is studied, the more support we have for the hypothesis. As a follow-up assignment, ask your students to read the freely available journal article published by a group of researchers in Germany who tested this same hypothesis (Dallacker et al., 2023). Ask students to address these questions: The primary hypothesis was “children eat more fruits and more vegetables when the regular family mealtime duration is extended.” What was their secondary hypothesis? What committee provided ethics approval? Was consent to participate in the study given by the caregiver, the child, or both? How many parent-child pairs participated in this experiment? How did researchers figure out how long the regular meal and the intervention meal should be? What was the experiment’s independent variable? What were the two conditions of the independent variable? How were these operationally defined? What were the experiment’s dependent variables? How were these operationally defined? Were the researchers’ primary and secondary hypotheses supported by their data? Explain.   References Dallacker, M., Knobl, V., Hertwig, R., & Mata, J. (2023).

On the first day of class, I give my students a few get-to-know-each-other questions to discuss in small groups. While they discuss, I visit the groups and invite them to ask any questions they may have about me. This semester during one such small group visit I had a student ask me for my zodiac sign. I said, “Scorpio. But you know that doesn’t mean anything, right?” She looked at me as if I were the naïve one. In retrospect, I could have handled that better. “Why do you ask?” “Do you believe that the time of year we’re born is the sole determinant of personality? Our genes and experiences don’t matter at all?” In any case, I didn’t think any more about it. And then two days ago (April 4, 2023), Google announced that their Waze app is adding a zodiac mode (Waze, 2023). And this month, Waze is tapping into the all-knowing cosmos to find out if you navigate like a Saggitarius or a Scorpio, thanks to the latest driving experience: Zodiac. Drive with a vehicle and Mood outfitted for your sign and embody your true colors on the road. Our navigation guide is well-versed in astrology and knows how to get all types of personalities to their final destination — whether you're a fiery Aries, a balanced Libra, an independent Aquarius, an ambitious Taurus, a spontaneous Gemini, an intuitive Cancer, a detail-oriented Virgo, an intense Capricorn, a whimsical Pisces, a dramatic Leo, a free-spirited Sagitttarius or a loyal Scorpio. She does it with love, life advice and a little teasing. The first thing I did was roll my eyes. The second thing I did was uninstall Waze. You would think that as a Scorpio I’d be more loyal than that. When we lived in the Seattle area, Waze was my go-to navigation app. Now that we live where there is much less traffic, I don’t need help getting around traffic jams so I haven’t used Waze in two years. I admit that haven’t kept up with Waze’s fun features. I just reinstalled Waze to see how zodiac mode works. Unfortunately—and to my great disappointment—zodiac mode has not rolled out to my phone, yet. There are, however, several other ways for me to “customize my drive.” If I select zombie mode, the driving directions are delivered in a zombie voice—or rather, what someone imagines a zombie voice would sound like, the car icon I see is decaying green, and the icon that appears to other drivers is a stitched up gray blob. That helps me envision a bit what zodiac mode might look like. Just like the 70s/80s/90s mode or the cat/dog mode, I suppose zodiac mode is meant to be a new, fun, quirky way to get to and from wherever you need to be. While there probably aren’t many people who believe in zombies, a Pew Research Center survey found that 29% of U.S. adults believe in astrology (Gecewicz, 2018). You can assume that about a third of your students hold such a belief. Among college graduates however, the survey found that the number that believed in astrology dropped to 22% (Gecewicz, 2018). I credit the personality chapter in the Intro Psych course for that decrease. Ok. I don’t know that. It’s an empirical question, though, for someone looking for a research project. If you’d like to give your students some research practice in the personality chapter, point out that about a third of people in the U.S. believe that zodiac signs affect personality. Zodiac signs, however, were not included in our textbook’s personality chapter as a contributing factor. How could we find out if one’s zodiac sign affects personality? Give students a couple of minutes to think about this question on their own, and then ask them to discuss in small groups. The research designs will likely include some measuring of personality traits. The biggest challenge here may be finding two astrological experts who agree on the characteristics each sign is supposed to have. As another variable, students may suggest asking study participants for their sign. It’s possible that asking outright for a zodiac sign may prime the potentially one-third of participants who believe in the zodiac to skew their personality answers. There are at least two ways around this: ask for birthday and determine zodiac sign yourself or ask for the zodiac sign at the very end after all of the personality questions have been answered. Asking for birthday is probably safest as some volunteers may not know their zodiac sign. Also point out that birthdays don’t have meaning in some cultures, so members of those cultural groups don’t know the date of their birth. When a birthday is needed, they may use January 1. A good question for students to consider is how they could ask if a participant knows their birth date. If time allows, consider asking this question about ethics that I’ve been thinking about a lot lately. Do we each have a responsibility to share and only share factually correct information? If we know what we’re sharing is false or suspect that it might be, do we have a responsibility to say so? As a professor of psychology, I certainly have an ethical responsibility to share evidence-based information about psychology. If the evidence is lacking, then I need to make it clear that the evidence is lacking. Does a producer or film company have a responsibility to depict accurately how drugs work, how memory works, how psychological disorders work? Especially given how many people learn about these topics through media? When a tech company uses the zodiac to make commuting more fun, are they promoting—whether intentionally or unintentionally—belief in the stars having an impact on personality?   References Gecewicz, C.

It is not often that the New York Times publishes an article on operational definitions. Okay, they don’t call them operational definitions, but that’s what they are. Introduce this assignment by describing how so much of our health is influenced by our behaviors. If behavior is involved, psychology is there. How do researchers—or ourselves, for that matter—know if changes in our behavior, e.g., exercise, more nutritious eating, is positively affecting our level of fitness? The easy answer is that we randomly assign volunteers to, say, an exercise program of some sort or to a control group—maybe even a waitlist control group—and then after a predetermined amount of time, we measure their fitness. Great! Now, how do we measure fitness? Probably the most common way the average person on the street measures their fitness is by hopping on the scale. The more fat we carry, the greater the potential impact on our health. Since both fat and muscle have weight, the average scale does not differentiate. It is possible that the more we exercise, the more fat we lose but the more muscle mass we gain. Even though our fitness is increasing, our scales may tell us that we weigh the same or are actually gaining weight. Then there’s the body mass index (BMI). This is another measurement that does not differentiate between fat and muscle. The BMI is not lacking for critics. As one observer pointed out, the current BMI categories are not useful. Several longitudinal studies, they report, have found being BMI overweight (BMI 25-29.9) or in the first level of BMI obese (30-34.9) had little or no impact on mortality rates (Nuttall, 2015). What if we could just measure the amount of fat that we carry? There are scales that purport to do that. Such scales send an electrical current through your body. Water is an excellent conductor of electricity. Muscle contains more water than fat. The less resistance the electrical current encounters, the more muscle mass the scale concludes we have. The scales that have only two points of measurement—two feet—are less accurate than scales that have four points of measurement—two feet and two hands, but the two-point scales are considerably less expensive. The two-point scales tend to be reliable, but not accurate, underestimating or overestimating fat content significantly. However, if one is using such a scale to track changes, then they do fine. One more important point about these scales. If you’re dehydrated, the scale’s electrical current will meet more resistance, and the scale will say that we have more body fat than we have (McCallum, 2022). None of these measurements—overall weight, BMI, or fat composition—identify where our fat is concentrated. Abdominal fat is associated with poorer health outcomes than, say, fat stored in the lower body. The latter may actually have protective effects (de Lemos, 2020). If these measurements are not the best way to operationally define fitness, what are some alternatives? If you’d like to make this an out of class assignment, ask your students to read this New York Times article (Smith, 2023). The article identifies three different approaches to measuring fitness: heart metrics, physical performance metrics, and daily living metrics. Ask students to identify at least three operational definitions of fitness provided in the article for each approach.   References de Lemos, J. (2020, December 16).

Every discipline has their zombie ideas, even library science. This could be a good discussion to have with students in the Intro Psych research methods chapter regarding the pitfalls of common sense. Ask students via clicker, Plickers, or by a show of hands this question: When touching the pages of old, valuable books, you should wear white gloves. Yes, no, or I don’t know? Most of your students will likely say yes. Now ask how do they know? This will be a harder question for them to answer. They may not remember how they learned this. They may even say that it’s common sense. Common sense may be common in that a whole lot of people think it is true, but that doesn’t make it true. And that’s the case with wearing white gloves when touching the pages of old, valuable books. In this New York Times article, librarians describe this belief of needing to wear white gloves when handling the pages of old, valuable books as an idea that will not die (Schuessler, 2023)—a zombie idea, if you will. The rationale for why wearing white gloves is a bad idea is good: “Gloves reduce your sense of touch, increasing the likelihood that you might accidentally tear a page, smear pigments, dislodge loose fragments — or worse, drop the book” (Schuessler, 2023). Gloves also tend to gather dirt and cause hands to sweat (Schuessler, 2023). Dirt and moisture are bad for books. The librarians remind us that the books have been handled with bare hands for as long as they have been around. There are a few exceptions to the no-glove rule, however. Nitrile gloves are recommended for photographic pages and certain book covers (e.g., book covers that contain metal, ivory, velvet, and certain other types of cloth). Also, wearing gloves is a good idea for handling book covers that may contain arsenic, but that’s for protecting the reader, not the book. Although one librarian added, “The moral of the story is, don’t lick the books and you will be fine” (Schuessler, 2023). Don’t lick the books. Got it. If the white glove thing isn’t actually a thing, why did Sotheby’s take a photograph of Brontë family manuscripts with white-gloved hands (Schuessler, 2021)? They are likely taking advantage of our ‘common sense’ for their monetary gain. If white gloves signal ‘valuable book,’ then we may be likely to pay more money for it (Schuessler, 2023). No white gloves? Then perhaps the book is no different than the paperback we picked up last week from our local bookseller. If you’d like to expand this discussion into one of ethics, ask your students if some of their ‘common sense’ knowledge comes from what they’ve seen in movies or television shows. Do producers and writers have an ethical obligation to present accurate information or to note when they are not? What about the creators of YouTube or TikTok videos? If the content creators do not have such an ethical obligation, does the responsibility then lie with the viewer to sort out what is fact and what is fiction? If so—and if we choose not to expend the time and energy to do so—then are we at risk for spreading misinformation? This could be a good opportunity to launch a discussion on the importance of information literacy.   References Schuessler, J. (2021, May 25). A lost Brontë library surfaces.

The following would fit well with a discussion research methods, but would also work as a research methods booster in the social or emotion chapters. In a series of studies conducted under different field and lab conditions, researchers gave participants opportunities to engage in random act of kindness to evaluate the impact that kindness had on both the giver and the recipient (Kumar & Epley, 2022) (freely available). For the purpose of this blog post, I want to focus on study 2a: hot chocolate at the skating rink. After reading several of Kumar and Epley’s studies in this article, it makes me want to do random acts of kindness research. I want to spend a chunk of my day brainstorming random acts of kindness that I could encourage participants to do. I’m picturing Amit Kumar and Nicholas Epley sitting around on a cold day, and one of them saying, “You know what makes me happy? A hot beverage on a cold day.” And the other saying, “Especially if I’m really cold and the hot beverage is extra tasty.” It’s a short leap from there to an outdoor skating rink and hot chocolate. With the permission of the skating rink operators, researchers approached people, told them that they were conducting a study, and gave them a choice. Here’s a cup of hot chocolate. You can keep it for yourself or you can point out anyone here, and we’ll deliver it to the person. The researchers made deliberate use of demand characteristics to encourage giving away the hot chocolate. I’m picturing something like this spiel, “The entire reason we’re out here, bub, is to investigate the effects of random acts of kindness, so we’d really love it if you’d give this hot chocolate away. But, hey, if you want to keep it, you selfish lout, there’s nothing we can do about it.” Okay, they probably didn’t call them selfish louts, although that would have upped the demand characteristics ante. While 75 people agreed to give the hot chocolate away, nine (very cold people with low blood sugar perhaps) opted to keep it. The givers each identified one person at the outdoor skating rink to receive a hot chocolate delivery. For the dependent variables, each hot chocolate donor was asked three questions: how big do they think this act of kindness is (scale of 0 to 10), what’s your mood now having made the decision to give away the hot chocolate compared to normal (-5 to +5, where 0 is normal), and what they thought the mood of the recipient would be upon receiving the hot chocolate (same scale, -5 to +5 where 0 is normal).   Next, the researchers approached the identified recipients, explained that they were conducting a study, and that they gave people the choice to keep or give away a cup of hot chocolate. They further explained that a person chose to give away their cup of hot chocolate to them. At this point, I’m a little sorry that this was not a study of facial expressions. I would imagine that looks of confusion would dominate, at least at first. Imagine standing at an outdoor ice skating rink when a complete stranger comes up to you, says they’re conducting a study, and, here, have a cup of hot chocolate. After confusion, perhaps surprise or joy. Or perhaps skepticism. The researchers did not report how many hot chocolate recipients actually drank their beverage. Also no word on how happy the researchers were since they were the ones who were actually giving away hot chocolate. After being handed the cup of hot chocolate, each recipient was asked to rate how big this act of kindness was (0 to 10 scale) and to report their mood (scale of -5 to +5, where 0 is normal). The design of this study makes the data analysis interesting. The mood of the givers and the mood of the recipients was each treated as a within participants comparison. The reported mood (-5 to +5) was compared against 0 (normal mood). The givers, on average, reported a net positive mood of +2.4 (with +5 being the maximum). The recipients, on average, reported a net positive mood boost to +3.52. In a between participants comparison, givers and recipients were compared on the mood of recipients. When the givers were asked what the mood would be of the participants, they underestimated. They guessed an average of +2.73 as compared the actual rating the recipients gave their own mood of +3.52. As another between participants comparison, the ratings of how big the givers thought their act of kindness was (3.76 on an 11-point scale) were compared to how big the recipients thought the act of kindness was (7.0 on an 11-point scale).   Studies reported later in this article provide evidence that suggests that the difference in perspective between the givers of a random act of kindness and their recipients is that the givers attend to the act itself—such as the value of the hot chocolate—and not on the additional value of being singled out for kindness, no matter what that kindness is. To give students some practice at generating operational definitions, point out that Kumar and Epley operationally defined a random act of kindness as giving away hot chocolate. Ask students to consider some other operational definitions—some other ways Kumar and Epley could have created a random act of kindness situation but using the same basic study design. Point out that researchers could use these other operational definitions to do a conceptual replication of this study—same concepts, but different definitions. Maybe some of your students will even choose to engage in some of those random acts of kindness.   Reference Kumar, A., & Epley, N. (2022).

When I discuss experimental design in Intro Psych, I usually focus on the independent variable and dependent variable and how they are operationally defined as well as design considerations such as the experimenters and participants being blind to conditions. (I’ve read some articles where the authors say that the experimenters and participants were blinded. It brings me up short every time.) It wouldn’t hurt me to spend a little time talking about external validity, especially how we may sacrifice external validity in a lab study as a sort of proof of concept, and then follow up with a study that has more external validity. A recent JAMA article provides a nice illustration of how this can work—and gives students some experimental design practice. After covering experimental design, describe this freely available study on fast food menu choices (Wolfson et al., 2022). The researchers hypothesized that the study “participants would be more likely to select sustainable options when viewing menus with positive or negative framing compared with control labels.” In an online questionnaire, 5,049 “[p]articipants were shown a fast food menu and prompted to select 1 item they would like to order for dinner.” The independent variable was menu labeling. “Participants were randomized to view menus with 1 of 3 label conditions: a quick response code label on all items (control group); green low–climate impact label on chicken, fish, or vegetarian items (positive framing); or red high–climate impact label on red meat items (negative framing).” The primary dependent variable was the number of participants who selected a menu item that was not red meat. In the control condition, 49.5% of participants selected something other than red meat. In the positive framing condition (green labels on non-red meat items), 54.4% selected something other than red meat. In the negative framing condition (red labels on red meat items), 61.1% selected something other than red meat. All differences were statistically significant. In the limitations section of the article, the researchers acknowledge that this study assessed hypothetical food purchases rather than actual food purchases. As such, the study lacks external validity. They also acknowledge that social desirability may have also influenced the results, but they think that the anonymity of the online study may have mitigated the effects. I’m less convinced. Participants may have been more likely to select non-red meat options partly to look like better people to themselves and partly because they guessed the hypothesis and wanted to help out the researchers. In any case, this study found positive results that may be worth investigating further. The challenge for your students is to design a study that has greater external validity. How could the same research hypothesis be tested in real world conditions? Give students a couple minutes to think about this on their own and then ask students to discuss in small groups. What problems can students envision in conducting such a study? For example, would a local fast food restaurant be okay with putting red or green labels on their menu boards? One last comment about social desirability. In a real fast food restaurant, if someone chose to order a green-labeled item, for the purpose of the hypothesis, does it matter if they ordered it because they wanted to have a positive impact (or less negative impact) on the planet, because they wanted to think of themselves as a good person, or because they wanted to look good to others?   References Wolfson, J.

“Older adults report surprisingly positive affective experience. The idea that older adults are better at emotion regulation has emerged as an intuitively appealing explanation for why they report such high levels of affective well-being despite other age-related declines” (Isaacowitz, 2022). Our schemas and the assumptions that come with them influence how we see the world and, in turn, influence how we talk about the world. As instructors and researchers we need to consider how our assumptions can weasel their way into what we say and what we write. I’ve been thinking a lot lately about ageism. Certainly, how we think about aging varies by culture. In some cultures, for example, elders are revered for their knowledge and wisdom. In others, aging is viewed as a gradual decline into an inevitable physical and cognitive wasteland. Unfortunately for me, my dominant culture is the latter. This schema that has been drilled into my head, however, has amassed so many exceptions that I’m not sure that I still have the schema. I have many friends who are in their 70s and 80s. They are all physically active and intellectual powerhouses. Every one of them. When I read the opening two sentences of Isaacowitz’s aging and emotion regulation article in Perspectives on Psychological Science quoted at the beginning of this blog post, I was first puzzled. “Older adults report surprisingly positive affective experience.” Surprisingly? You’re surprised that older adults are happy? Why is this surprising? “The idea that older adults are better at emotion regulation has emerged as an intuitively appealing explanation for why they report such high levels of affective well-being despite other age-related declines.” Oh. You’re surprised because you believe that older adults live in a physical and cognitive wasteland, so how could they possibly be happy. This needs an explanation! It even has a name: the paradox of aging. “There is an extensive, robust literature suggesting that older adults self-report quite positive emotional lives; sometimes they even report being more emotionally positive than their younger counterparts” (Isaacowitz, 2022). [Gasp!] The question is not why younger people aren’t happier. The question is why older adults are. Some researchers think that older adults are happier because older adults are better at regulating emotions. Isaacowitz’s article provides a nice summary of the research into this explanation and concludes that the evidence is inconclusive. The article ends with this: “the robust finding of older adults’ positive affective experience remains to be well-explained. This is a mystery for future researchers still to unravel” (Isaacowitz, 2022). This article was a nice reminder for me to consider my own schemas and assumptions when I talk with my students about any psychological topic. For example, I knew an instructor who would talk about people who were diagnosed with a psychological disorder as suffering from the disorder. I know people with a variety of diagnoses who manage, live with, and experience psychological disorders. The word suffer brings with it a set of assumptions that I don’t share. I admit that I have my own baggage here. I have a chronic physical condition that if not well-managed could kill me which I manage, live with, and experience. I most certainly do not suffer from it. Maybe we should be also asking how I—a person with such a condition—could possibly be so gosh darn happy. If in the Intro Psych research methods chapter you discuss how a researcher’s values affect the topics they choose to research, discussion of this article may be a good example. It’s a nice illustration of why researchers from a diversity of backgrounds is so important to science. Would, for example, a researcher from a culture that reveres older adults wonder why older adults are happy? If you’d like to explore more about cultural ageism and its impact, I highly recommend Becca Levy’s 2022 book, Breaking the Age Code. It will change how you think about—and talk about—aging.   Reference Isaacowitz, D. M. (2022). What do we know about aging and emotion regulation?

I think of the Intro Psych course as an owner’s manual for being human. Throughout the course, we explore the multitude of ways we are influenced to think, feel, or behave a certain way that happens without our conscious awareness. Here’s one such example we can use to give our students some experimental design practice. It’s suitable for the methods chapter or, if you cover drugs, in that chapter after discussing caffeine. Caffeine, as a stimulant, increases arousal. It’s plausible that consumers who are physiologically aroused engage in more impulsive shopping and, thus, spend more money than their uncaffeinated counterparts. Give students this hypothesis: If shoppers consume caffeine immediately before shopping, then they will spend more money. Ask students to take a couple minutes thinking about how they would design this study, and then invite students to share their ideas in pairs or small groups. Ask the groups to identify their independent variable (including experimental and control conditions) and their dependent variable. If you cover operational definitions, ask for those, too. Invite groups to share their designs with the class. Emphasize that there is no one right way to conduct a study. Each design will have its flaws, so using different designs to test the same hypothesis will give us greater confidence in the hypothesis. Share with students the first two of five experiments reported in the Journal of Marketing (Biswas et al., 2022). In study 1, researchers set up a free espresso station just inside the front door of a store. As shoppers entered, they were offered a cup of espresso. The experiment was conducted at different times of day over several days. At certain times, shoppers were offered a caffeinated espresso. At other times, they were offered a decaffeinated espresso. As the espresso drinkers left the store after having completed their shopping, researchers asked if they could see their receipts. Everyone said yes. Researchers recorded the number of items purchased and the total purchase amount. (Ask students to identify the independent and dependent variables.) As hypothesized, the caffeinated shoppers purchased more items (2.16 vs. 1.45) and spent more money (€27.48 vs. €14.82) than the decaffeinated shoppers. Note that participants knew whether they were consuming a caffeinated or decaffeinated beverage, but did not know when they accepted that they were participating in a study. There are a few ethical questions about study 1 worth exploring with your students. First, this study lacked informed consent. Participants were not aware that they were participating in a study when they accepted the free espresso. As participants were leaving, it became clear to them that they were participating in a study. Given the norm of reciprocity, did participants see not handing over their receipts as a viable option? Lastly, the researchers expected that caffeine would increase consumer spending. In fact, it nearly doubled it. Was it ethical for the researchers to put unwitting shoppers in a position to spend more money than they had intended? In study 2, students from a marketing research class “in exchange for course credit” were asked to recruit family or friends to participate. The volunteers, who were told that this was a study about their shopping experience, were randomly assigned to an espresso or water condition which were consumed in a cafeteria next to a department store. After consuming their beverages, the volunteers were escorted to the department store and were asked to spend two hours in the store “shopping or looking around.” As in study 1, caffeinated shoppers spent nearly twice as much money (€69.91 vs. €39.63). Again, we have the ethical question of putting unwitting shoppers in the position to spend more money than they would have. We also have the ethical question of students recruiting friends and family to participate as course requirement. And then from a design perspective, how certain can we be that the students didn’t share the hypothesis with their family and friends? Is it possible that some of the students thought that if the study’s results didn’t support the hypothesis, their grade would be affected? As a final ethics question, what should we do with the knowledge that we are likely to spend (much) more money when shopping when we are caffeinated? As a shopper, it’s easy. I’m not going stop on the coffee shop on my way to the store. For a store manager whose job it is to maximize, it’s also easy. Give away cups of coffee as shoppers enter the store. The amount of money it costs to staff a station and serve coffee will more than pay for itself in shopper spending. Here’s the bigger problem. Is it okay to manipulate shoppers in this way for financial gain? Advertising and other persuasive strategies do this all the time. Is free caffeine any different? Or should coffee cups carry warning labels? To close this discussion, ask students in what other places or situations can impulsive behavior encouraged by being caffeinated be problematic. Casinos come readily to my mind. Are caffeinated people likely to bet more? Would that study be ethical to conduct?   Reference Biswas, D., Hartmann, P., Eisend, M., Szocs, C., Jochims, B., Apaolaza, V., Hermann, E., López, C. M., & Borges, A. (2022).

Men in the United States are four times more likely to die by suicide than are women (Curtin et al., 2022), and men are almost half as likely to receive mental health treatment than are women (Terlizzi & Norris, 2021). This is seriously problematic, as pointed out by a December 2022 New York Times article (Smith, 2022). In the Intro Psych therapy chapter, share the above statistics with students. Ask your students to discuss in small groups why they think men are less likely to receive mental health treatment. (While what is described here is for a face-to-face class, the discussion can be adapted for asynchronous discussions.) To take away some of what could be very personal, ask students to consider why their male friends or male relatives might not be inclined to seek mental health treatment. If your male students choose to share their own thoughts, that’s fine; just don’t pressure them to do so. Invite the groups to share the reasons they generated with the class. Record the reasons in a way that students can view them. Next invite your students to visit the Man Therapy website (mantherapy.org). What are their favorite article titles? I’m partial to “Sometimes a man needs a pork shoulder to cry on” and “Anxiety: When worry grabs you by the [nether parts]” with an honorable mention for “Sleep: When catching z’s is harder than catching a 20lb trout.” Do your students think that the messaging about mental health on this website would resonate with the men in their lives? Why or why not? Do your students think different messaging would work better for different cultural or ethnic groups? If so, what might that look like? If you’d like to extend this discussion, ask students if they were interested in sharing the mantherapy.org link with their male friends and relatives. For your students who are game, ask them to send out texts right now while in class. If texts come back while you are still in class, invite students to share them. Check back in with students during the next class for reactions that students received after class. If time allows and you are so inclined, ask students to work in small groups to design an experiment that would evaluate the effectiveness of a website such as mantherapy.org. What would their hypothesis be? What would be their measure of effectiveness? What would be their control condition? How would they identify and recruit participants. If your class, department, psych club, or psych honor society thinks that mantherapy.org could be effective at increasing men’s access to mental healthcare, you can “become a champion” by visiting this page and completing the form at the bottom. You will receive a “shipment of printed collateral including posters, wallet cards, and stickers to help get the word out and drive traffic to the site.” There is no mention of a cost for these materials.   References Curtin, S.

The Intro Psych therapy chapter is a good place to reinforce what students have learned about research methods throughout the course. In this freely available 2022 study, researchers wondered about the effectiveness of a particular medication (naltrexone combined with bupropion) and a particular type of psychotherapy (behavioral weight loss therapy) as a treatment for binge-eating disorder (Grilo et al., 2022). First, give students a bit of background about binge-eating disorder. If you don’t have the DSM-V (with or without the TR) handy, this Mayo Clinic webpage may give you what you need (Mayo Clinic Staff, 2018). Next, let students know that naltrexone-bupropion work together on the hypothalamus to both reduce how much we eat and increase the amount of energy we expend (Sherman et al., 2016). It’s a drug combination approved by the FDA for weight loss. Lastly, behavioral weight loss therapy is all about gradual changes to lifestyle. That includes gradual decreases in daily calories consumed, gradual increases in nutritional quality, and gradual increases in exercise.   Invite students to consider how they would design an experiment to find out which treatment is most effective for binge-eating disorder: naltrexone-bupropion, behavioral weight loss (BWL) therapy, or both. In this particular study ("a randomized double-blind placebo-controlled trial"), researchers used a 2 (drug vs. placebo) x 2 (BWL vs no therapy) between participants design. In their discussion, they note that, in retrospect, a BWL therapy group alone would have been a good thing to have. The study was carried out over a 16-week period. Participants were randomly assigned to condition. Researchers conducting the assessments were blind to conditions. Next ask students what their dependent variables would be. The researchers had two primary dependent variables. They measured binge-eating remission rates, with remission defined as no self-reported instances of binge eating in the last 28 days. They also recorded the number of participants who lost 5% or more of their body weight. Ready for the results? Percentage of participants who had no binge-eating instances in the last 28 days   Placebo Naltrexone-Bupropion No therapy 17.7% 31.3% BWL therapy 37.% 57.1%   Number of participants who lost 5% or more of their body weight   Placebo Naltrexone-Bupropion No therapy 11.8% 18.8% BWL therapy 31.4% 37.1%   As studies that have evaluated treatments for other psychological disorders have found, medication and psychotherapy combined are more effective than either alone. If time allows, you can help students gain a greater appreciation for how difficult getting participants for this kind of research can be. Through advertising, the researchers heard from 3,620 people who were interested. Of those, 972 never responded after the initial contact. That left 2,648 to be screened for whether they would be appropriate for the study. Following the screening, only 289 potential participants were left. Ask students why they think so few participants remained. Here are the top reasons: participants did not meet the criteria for binge-eating disorder (715), participants decided they were not interested after all (463), and participants were taking a medication that could not be mixed with naltrexone-bupropion (437). Other reasons included but not limited to having a medical condition (could impact study’s results), they were already in a treatment program for weight loss or binge-eating disorder (would not be a sole test of these treatments), or they were pregnant or breast-feeding (couldn’t take the drugs). After signing the consent form and doing the initial assessment, another 153 were found to have not met the inclusion criteria. That left 136 to be randomly assigned to conditions. Over the 16 weeks of the study, 20 participants dropped out on their own, and four were removed because of medical reasons. It took 3,620 people who expressed interest to end up with data from 112 participants. There is no information in the article about whether participants who were not in the drug/psychotherapy group were offered—after the study was over—the opportunity to experience the combined treatment that was so effective. Ethically, it would have been the right thing to do.   References Grilo, C. M., Lydecker, J. A., Fineberg, S. K., Moreno, J. O., Ivezaj, V., & Gueorguieva, R. (2022).

I have had occasion to send out emails with some sort of inquiry. When I don’t get any response, it ticks me off. I don’t do well with being ignored. I’ve learned that about me. Even a short “I’m not the person to help you. Good luck!” would be welcome. I mention that to acknowledge that I brought that particular baggage with me when I read an article in the Journal of Counseling Psychology about counselors ignoring email messages from people seeking a counselor (Hwang & Fujimoto, 2022). As if the bias this study revealed was not anger-inducing enough. The results are not particularly surprising, but that does not make me less angry. I’ve noticed that as I’m writing this, I’m pounding on my keyboard. Wei-Chin Hwang and Ken A. Fujimoto were interested in finding out how counselors would respond to email inquiries from potential clients who varied on probable race, probably gender, psychological disorder, and inquiry about a sliding fee scale. The researchers used an unidentified “popular online directory to identify therapists who were providing psychotherapeutic services in Chicago, Illinois” (Hwang & Fujimoto, 2022, p. 693). From the full list 2,323 providers, they identified 720 to contact. In the first two paragraphs of their methods section, Hwang and Fujimoto explain their selection criteria. The criterion that eliminated the most therapists was that the therapist needed to have an advertised email address. Many of the therapists listed only permitted contact through the database. Because the researchers did not want to violate the database’s terms of service, they opted not to contact therapists this way. They also excluded everyone who said that they only accepted clients within a specialty area, such as sports psychology. They also had to find a solution for group practices where two or more therapists from the same practice were in the database. Hwang and Fujimoto did not want to risk therapists in the same group practice comparing email requests with each other, so they randomly chose one therapist in a group practice to receive their email. This experiment was a 3x3x2x2 (whew!). Inquirer’s race: White, African American, Latinx American (the three most common racial groups in Chicago, where the study was conducted). Researchers used U.S. Census Bureau data to identify last names that were most common for each racial group: Olson (White), Washington (African American), and Rodriguez (Latinx). Inquirer’s diagnosis: Depression, schizophrenia, borderline personality disorder (previous research has shown that providers find people with schizophrenia or borderline personality disorder less desirable to work with than, say, depression) Inquirer’s gender: Male, female. (Male first names: Richard, Deshawn, José; female first names: Molly, Precious, and Juana) Inquirer’s ability to pay full fee: Yes, no. In their methods section, Hwang and Fujimoto include the scripts they used. Each script includes this question: “Can you email me back so that I can make an appointment?” The dependent variable was responsiveness. Did the provider email the potential client back within two weeks? If not, that was coded as “no responsiveness.” (In the article’s Table 1, the “no responsiveness” column is labeled as “low responsiveness,” but the text makes it clear that this column is “no responsiveness.”) If the provider replied but stated they could not treat the inquirer, that was coded as “some responsiveness.” If the provided replied with the offer of an appointment or an invitation to discuss further, that was coded as “high responsiveness.” There were main effects for inquirer race, diagnosis, and ability to pay the full fee. The cells refer to the percentage of provider’s email messages in each category. Table 1. Responsiveness by Race of Inquirer Name No responsiveness Some responsiveness High responsiveness Molly or Richard Olson 15.4% 33.2% 51.5% Precious or Deshawn Washington 27.4% 30.3% 42.3% Juana or José Rodriguez 22.3% 34% 43.7%   There was one statistically significant interaction. Male providers were much more likely to respond to Olson than they were to Washington or Rodriguez. Female providers showed no bias in responding by race. If a therapist does not want to work with a client based on their race, then it is probably best for the client if they don’t. But at least have the decency to reply to their email with some lie about how you’re not taking on more clients, and then refer them to a therapist who can help. Table 2. Responsiveness by Diagnosis Diagnosis No responsiveness Some responsiveness High responsiveness Depression 17.9% 20% 62.1% Schizophrenia 25.8% 43.8% 30.4% Borderline Personality Disorder 21.3% 33.8% 45%   Similar thoughts here. I get that working with a client diagnosed with schizophrenia or borderline personality disorder takes a very specific set of skills that not all therapists have, but, again, at least have the decency to reply to the email saying that you don’t have the skills, and then refer them to a therapist who does. Table 3. Responsiveness by Inquirer’s Ability to Pay Full Fee Ability to pay full fee No responsiveness Some responsiveness High responsiveness No 22.4% 39.7% 38% Yes 21% 25.4% 53.6%   While Hwang and Fujimoto interpret these results to mean a bias against members of the working class, I have a different interpretation. The no response rate was the same with about 20% of providers not replying at all. If there were an anti-working-class bias, I would expect the no responsiveness percentage to those asking about a sliding fee scale would be much greater. In both levels of this independent variable, about 80% gave some reply. It could be that the greater percentage of “some responsiveness” in reply to those who inquired about a sliding fee scale was due to the providers being maxed out on the number of clients they had who were paying reduced fees. One place to discuss this study and its findings with Intro Psych students is in the therapy chapter. It would work well as part of your coverage of therapy ethics codes. Within the ethics code for the American Counseling Association, Section C on professional responsibility is especially relevant. It reads in part: Counselors facilitate access to counseling services, and they practice in a nondiscriminatory manner…Counselors are encouraged to contribute to society by devoting a portion of their professional activity to services for which there is little or no financial return (pro bono publico) (American Counseling Association, 2014, p. 😎 Within the ethics code of the American Psychological Association, Principle 😧 Social Justice is particularly relevant. Psychologists recognize that fairness and justice entitle all persons to access to and benefit from the contributions of psychology and to equal quality in the processes, procedures, and services being conducted by psychologists. Psychologists exercise reasonable judgment and take precautions to ensure that their potential biases, the boundaries of their competence, and the limitations of their expertise do not lead to or condone unjust practices (American Psychological Association, 2017). Principle E: Respect for People's Rights and Dignity is also relevant. It reads in part: Psychologists are aware of and respect cultural, individual, and role differences, including those based on age, gender, gender identity, race, ethnicity, culture, national origin, religion, sexual orientation, disability, language, and socioeconomic status, and consider these factors when working with members of such groups. Psychologists try to eliminate the effect on their work of biases based on those factors, and they do not knowingly participate in or condone activities of others based upon such prejudices (American Psychological Association, 2017). This study was conducted in February 2018—before the pandemic. Public mental health has not gotten better. Asking for help is not easy. When people muster the courage to ask for help, the absolute least we can do is reply. Even if we are not the best person to provide that help, we can direct them to additional resources, such as one of these crisis help lines. For a trained and licensed therapist who is bound by their profession’s code of ethics to just not reply at all to a request for help, I just don’t have the words. Again, I should acknowledge that I have my own baggage about having my email messages ignored. For anyone who wants to blame their lack of responding on the volume of email you have sort through (I won’t ask if you are selectively not responding based on perceived inquirer personal characteristics), I have an hour-long workshop that will help you get your email under control and keep it that way.   References American Counseling Association.

I have been doing a bit of digging into the research databases, and I came across a Journal of Eating Disorders article with a 112-word “Plain English summary” (Alberga et al., 2018). I love this so much I can hardly stand it. Steven Pinker (2014) wrote an article for The Chronicle of Higher Education titled “Why academics’ writing stinks.” Pinker does not pull any punches in his assessment. Let’s face it. Some academic writing is virtually unreadable. Other academic writing is actually unreadable. Part of the problem is one of audience. If a researcher is writing for other researchers in their very specific corner of the research world, of course they are going to use jargon and make assumptions about what their readers know. That, though, is problematic for the rest of us. I have spent my career translating psychological science as an instructor and, more recently, as an author. This is what teaching is all about: translation. If we are teaching in our particular subdiscipline, translation is usually not difficult. If we are teaching Intro Psych, though, we have to translate research writing that is miles away from our subdiscipline. This is what makes Intro Psych the most difficult course in the psychology curriculum to teach. I know instructors who do not cover, for example, biopsychology or sensation and perception in their Intro Psych courses because they do not understand the topics themselves. Additionally, some of our students have learned through reading academic writing to write in a similarly incomprehensible style. Sometimes I feel like students initially wrote their papers in plain English, and then they threw a thesaurus at it to make their writing sound more academic. We have certainly gone wrong somewhere if ‘academic’ has come to mean ‘incomprehensible.’ I appreciate the steps some journals have taken to encourage or require article authors to tell readers why their research is important. In the Society for the Teaching of Psychology’s journal Teaching of Psychology, for example, the abstract ends with a “Teaching Implications” section. Many other journals now require a “Public Significance Statement” or a “Translational Abstract” (what the Journal of Eating Disorders calls a “plain English summary”). I have read my share of public significance statements. I confess that sometimes it is difficult—impossible even—to see the significance of the research to the general public in the statements. I suspect it is because the authors themselves do not see any public significance. That is probably truer for (some areas of) basic research than it is for any area of applied research. Translational abstracts, in contrast, are traditional abstracts rewritten for a lay audience. APA’s page on “Guidance for translational abstracts and public significance statements” (APA, 2018) is worth a read. An assignment where students write both translational abstracts and public significance statements for existing journal articles gives students some excellent writing practice. In both cases, students have to understand the study they are writing about, translate it for a general audience, and explain why the study matters. And maybe—just maybe—as this generation of college students become researchers and then journal editors, in a couple generations plain English academic writing will be the norm. This is just one of several windmills I am tilting at these days.   The following is a possible writing assignment. While it can be assigned after covering research methods, it may work better later in the course. For example, after covering development, provide students with a list of articles related to development that they can choose from. While curating a list of articles means more work for you up front, students will struggle less to find article abstracts that they can understand, and your scoring of their assignments will be easier since you will have a working knowledge of all of the articles students could choose from. Read the American Psychological Association’s (APA’s) “Guidance for translational abstracts and public significance statements.” Chose a journal article from this list of Beth Morling’s student-friendly psychology research articles (or give students a list of articles). In your paper: Copy/paste the article’s citation. Copy/paste the article’s abstract. Write your own translational abstract for the article. (The scoring rubric for this section will be based on APA’s “Guidance for translational abstracts and public significance statements.”) Write your own public significance statement. (The scoring rubric for this section will be based on APA’s “Guidance for translational abstracts and public significance statements.”)   References Alberga, A. S., Withnell, S. J., & von Ranson, K.

Here is another opportunity to give students practice in experimental design. While this discussion (synchronous or asynchronous) or assignment would work well after covering research methods, using it in the Intro Psych social psych chapter as a research methods refresher would work, too. By way of introduction, explain to your students how double-blind peer review works and why that’s our preferred approach in psychology. Next, ask students to read the freely-available, less-than-one-page article in the September 16, 2022 issue of Science titled “Reviewers Award Higher Marks When a Paper’s Author Is Famous.” While I have a lot of love for research designs that involves an entire research team brainstorming for months, I have a special place in my heart for research designs that must have occurred to someone in the middle of the night. This study has to be the latter. If you know it is not, please do not burst my bubble. A Nobel Prize winner (Vernon Smith) and his much lesser-known former student (Sabiou Inoua) wrote a paper and submitted it for publication in a finance journal. The journal editor and colleagues thought, “Hey, you know what would be interesting? Let’s find out if this paper would fly if the Nobel Prize winner’s name wasn’t on it. Doesn’t that sound like fun?” The study is comprised of two experiments (available in pre-print). In the first experiment, the experimenters contacted 3,300 researchers asking if they would be willing to review an economics paper based on a short description of the paper. Those contacted were randomly assigned to one of three conditions. Of the one-third who were told that the author was Smith, the Nobel laureate, 38.5% agreed to review the paper. Of the one-third who were told that the author was Inoua, the former student, 28.5% agreed to review. Lastly, of the one-third who were given no author names, 30.7% agreed to review. Even though there was no statistical difference between these latter two conditions as reported in the pre-print, the emotional difference must be there. If I’m Inoua, I can accept that many more people are interested in reviewing a Nobel laureate’s paper than are interested in reviewing mine. What’s harder to accept is that my paper appears even less interesting when my name is on it than when my name is not on it. I know. I know. Statistically, there is no difference. But, dang, if I were in Inoua’s shoes, it would be hard to get my heart to accept that. Questions for students: In the first experiment, what was the independent variable? Identify the independent variable’s experimental conditions and control condition. What was the dependent variable? Now let’s take a look at the second experiment. For their participants, the researchers limited themselves to those who had volunteered to review the paper when they had not been given the names of either of the authors. They randomly divided this group of reviewers into the same conditions as in the first experiment: author identified as Vernon Smith, author identified as Sabiou Inoua, and no author name given. How many reviewers recommended that the editor reject the paper? With Smith’s name on the paper, 22.6% said reject it. With Inoua’s name on the paper, 65.4% said reject. With no name on the paper, 48.2% said reject. All differences are statistically significant. Now standing in Inoua’s shoes, the statistical difference matches my emotional reaction. Thin comfort. Questions for students: In the second experiment, what was the independent variable? Identify the independent variable’s experimental conditions and control condition. What was the dependent variable? The researchers argue that their data reveal a status bias. If you put a high status name on a paper, more colleagues will be interested in reviewing it, and of those who do review it, more will advocate for its publication. Double-blind reviews really are fairer, although the researchers note that in some cases—especially with pre-prints or conference presentations—reviewers may know who the paper belongs to even if the editor conceals that information. With this pair of experiments, the paper sent out for review was not available as a pre-print nor had it been presented at a conference. The stickier question is how to interpret the high reject recommendations for Inoua as compared to when no author was given. While the experimenters intended to contrast Smith’s status with Inoua’s, there is a confounding variable. Reviewers who are not familiar with Sabiou Inoua will not know Inoua’s race or ethnicity for certain, but they might guess that Inouan is a person of color. A quick Google search finds Inoua’s photo and CV on Chapman University’s Economic Science Institute faculty and staff page. He is indeed a person of color from Niger. Is the higher rejection rate for when Inoua’s name was on the paper due to his lower status? Or due to his race or ethnicity? Or was it due to an interaction between the two? Questions for students: Design an experiment that would test whether Inoua’s higher rejection rate was more likely due to status or more likely due to race/ethnicity. Identify your independent variable(s), including the experimental and control conditions. Identify your dependent variable. If time allows, give students an opportunity to share other contexts where double-blind reviews are or would be better.     ... View more

In an example of archival research, researchers analyzed data from the U.S. National Health and Nutrition Examination Survey for the years 2007 to 2012 (Hecht et al., 2022). They found that after controlling for “age, gender, race/ethnicity, BMI, poverty level, smoking status and physical activity,” (p. 3) survey participants “with higher intakes of UPF [ultra-processed foods] report significantly more mild depression, as well as more mentally unhealthy and anxious days per month, and less zero mentally unhealthy or anxious days per month” (p. 7). So far, so good. The researchers go on to say, “it can be hypothesised that a diet high in UPF provides an unfavourable combination of biologically active food additives with low essential nutrient content which together have an adverse effect on mental health symptoms” (p. 7). I don’t disagree with that. It is one hypothesis. By controlling for their identified covariates, they address some possible third variables, such as poverty. However, at no place in their article do they acknowledge that the direction can be reversed. For example, it can also be hypothesized that people who are experiencing the adverse effects of mental health symptoms have a more difficult time consuming foods high in nutritional quality. Anyone who battles the symptoms of mental illness or who is close to someone who does knows that sometimes the best you can do for dinner is a hotdog or a frozen pizza—or if you can bring yourself to pick up your phone—pizza delivery.   They do, however, include reference to an experiment: “[I]n one randomized trial, which provides the most reliable evidence for small to moderate effects, those assigned to a 3-month healthy dietary intervention reported significant decreases in moderate-to-severe depression.” The evidence from that experiment looks pretty good (Jacka et al., 2017), although their groups were not equivalent on diet at baseline: the group that got the dietary counseling scored much lower on their dietary measure than did the group that got social support. Also, those who received social support during the study did, in the end, have better mental health scores and better diet scores than they did at baseline, although all we have are the means. I don’t know if the differences are statistically significant. All of that is to say is that the possibility remains that reducing the symptoms of mental illness may also increase nutritional quality. Both the Jacka et al. experiment and the Hecht et al. correlational study are freely available.   You may also want to read the Science Daily summary of the Hecht et al. study where the author (or editor?) writes, “Do you love those sugary-sweet beverages, reconstituted meat products and packaged snacks? You may want to reconsider based on a new study that explored whether individuals who consume higher amounts of ultra-processed food have more adverse mental health symptoms.” If you’d like to use this in your Intro Psych class, after covering correlations and experiments, ask your students to read the Science Daily summary. Ask your students two questions. 1) Is this a correlational study or an experiment? 2) From this study, can we conclude that ultra-processed foods negatively affect mental health? These questions lend themselves well for use with in-class student response systems (e.g., Clickers, Plickers). Lastly, you may want to share with your students more information about both the Hecht et al. study and the Jacka et al. experiment. If time allows, give your students an opportunity to design an experiment that would test this hypothesis: Improved mental health symptoms causes better nutritional consumption.   References Hecht, E.
