As of June 2023, recreational cannabis use is legal Canada (Department of Justice, Canada, 2021) and in 23 U.S. states, the District of Columbia, Guam, and the Northern Mariana Islands (Reuters, 2023). Not that it has to be legal for people to use it. In a 2022 national survey, researchers asked people about their marijuana use. Of full-time college students between the ages of 19 and 22, 22.1% reported that they used marijuana at least once in the last 30 days, whereas only 4.7% reported that they used it daily. Both numbers were lower than for age-matched non-college students (28.2% monthly and 14.5% daily). That 30-day percentage of 22.1% for college students is about where the numbers have been since 2013. To see these kind of numbers for marijuana use, we have to go back to the early 1980s. In 1980, a whopping one-third (34.8%) of college students reported using marijuana in the previous 30 days (Patrick et al., 2023). Why do college students use marijuana? In one qualitative study, one reason participants gave was that they used it for a boost in creativity (Kilwein et al., 2022). But does marijuana actually make users more creative? Or do they just think they are more creative? After covering experimental design, give your students this hypothesis: Cannabis use increases creativity. Ask students for the independent variable (including an experimental group and a control group) and the dependent variable(s). For all variables, ask for operational definitions. After students have had a couple minutes to consider this on their own, ask students to work in small groups to create their experimental design. If time allows, ask students how or where they would find volunteers for their study. What are the ethical concerns that they need to take into consideration? After group discussion dies down, ask a volunteer from each group to share their design. Now share with students how researchers investigated this same question (Heng et al., 2023). To recruit participants, researchers posted flyers in recreational cannabis dispensaries in Washington (a state where such use is legal) and on Craigslist. Users who smoked one joint no more than a few times a week were selected to participate. Anyone who reported being pregnant was excluded. Participants were mailed cannabis test kits and emailed the study information. Participants who successfully completed the study received a $25 gift card. Participants were randomly assigned to one of two conditions: high during the creativity test or not high during the creativity test. “High” was operationally defined as having used marijuana in the last 15 minutes. The researchers note that the participants had to supply their own cannabis. “Instead of stipulating a specific time to complete the study, participants were asked to begin the study within 15-min of their volitional cannabis use. This addressed the IRB restriction of not instructing cannabis use” (Heng et al., 2023, p. 637). Now we need an operational definition for creativity. “Participants were asked to generate as many creative uses as they could for a brick in 4 min” (Heng et al., 2023, p. 637). They also rated their brick ideas based on how creative, original, and novel they thought they were on a 5-point scale. Then they used the saliva test kit and mailed it back to the researchers. What did the researchers find? Participants who used cannabis before doing the creativity task thought they were more creative than did those in the control group. But were they really more creative” The researchers asked a couple research assistants who were blind to conditions to evaluate the creativity of the answers, and they also asked participants on Prolific to do the same. Neither the research assistants nor the Prolific participants saw any difference in creativity between the groups. There was a bit more to the research design if you’d like to share this with your students as a way to conclude this activity. The researchers also asked the participants how happy and joyful they were. The researchers found that it was this mood state that mediated creativity evaluations. Cannabis use was more likely to result in higher creativity ratings if the person was happy while high. References Department of Justice, Canada. (2021, July 7).

The Introduction to Psychology course is the hardest course to teach because we do not have expertise in the vast majority of the material. When you teach Intro Psych for the very first time, you get used to saying, “I don’t know.” As the years have rolled by, I’ve accepted that “I don’t know” is just part of my Intro Psych teaching lexicon. For me, however, it’s not the not knowing that’s problematic. It’s all of the information that I thought I knew, but, alas, did not. Finding out that I’ve gotten something wrong makes me wish I could contact all of my previous students and say, “Hey! Remember that thing I told you about? No, you don’t remember? Well, anyway, it turns out I was wrong. Here’s the right information. Or at least here’s the right information as we know it today.” Okay, maybe it’s best that I can’t contact my previous students. In some cases, the scientific research has given us updated information. For example, research published a week ago in Nature reveals that the motor cortex is not all about motor control (Gordon et al., 2023). There are pockets of neurons in between the motor control sections of the motor cortex that connect with other parts of the body. “As a result, the act of, say, reaching for a cup of coffee can directly influence blood pressure and heart rate. And the movement is seamlessly integrated into brain systems involved in planning, goals and emotion” (Hamilton, 2023). This is a beautiful example of the first of APA’s overarching themes for Intro Psych: “Psychological science relies on empirical evidence and adapts as new data develop” (Halonen et al., 2022) In some cases what I got wrong was me just not understanding. For example, if you used to teach that the cat running to the sound of the can opener was classical conditioning, you can identify with what I’m saying. (See this 2016 blog post for the explanation as to why this is not classical conditioning, but operant conditioning.) While I don’t have any suggestions on how we can speed up science, I do have some suggestions on how we can mitigate how much stuff we don’t understand, and, thus, mis-teach to our students. Here are some excellent books that will expand your Intro Psych knowledge. Most are written by experts in the field. Others were written by people who got deeply interested in the topic. If you have books that you have found useful for expanding your Intro Psych knowledge, please add them to the comments. Thanks!

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). Caffeine’s Effects on Consumer Spending.

In the June 2022 edition of the APA Monitor on Psychology is an excellent article on the psychology of traffic safety. The article features David Strayer’s “four horsemen of death”: speed, impairment, fatigue, and distraction. Given the number and breadth of psychological concepts covered, this article provides fodder for a good end-of-term assignment. It may also save the lives of your students. Note that the journalist uses the term “crash” rather than “accident.” “Crash” is the preferred term by U.S. government agencies, such as the CDC and the National Highway Traffic Safety Administration (NHTSA). The word “accident” implies an incident that could not be avoided. The word “crash” does not carry that connotation. Giving the causes of traffic fatalities are due to driver decision-making, whether it be the driver of the vehicle or the driver of another vehicle, “crash” is a better descriptor than “accident.” Ask students to read the article “Improving Traffic Safety” (Pappas, 2022), and then answer the following questions. How many people died on U.S. roadways in 2020? Speed. What percentage of the 2020 traffic fatalities were estimated to be caused by excessive speed? The article describes three ways that our environment can contribute to unsafe driving. Take a photo of a road in your area that illustrates one or more of these environmental hazards. Explain. The article also describes three ways that our environment can contribute to safe driving. Take a photo of a road in your area that illustrates one or more of these environmental benefits. Explain. In a survey of drivers at the beginning of the pandemic, researchers “saw an increase in respondents saying they were more likely to break the law because they knew they were less likely to be caught.” Explain this finding in terms of operant conditioning. With fewer people on the roads during the pandemic shut-down, researchers speculate that street racing may have increased. What Ontario law led to a reduction in street racing? Explain this effect in terms of operant conditioning. If you are primarily a driver, what can you do to reduce your chances of dying in a car crash due to speed? If you primarily a passenger, what can you do to reduce your chances of dying in a car crash due to speed? Impairment. What percentage of the 2020 traffic fatalities were estimated to be caused by impaired driving? Based on your reading of the article, describe the relationship between stress, alcohol, and driving while impaired. What Big Five personality trait is associated with a history of driving while impaired and reckless driving? Given your knowledge of this trait, why might that association exist? Fatigue. What percentage of the 2020 traffic fatalities were estimated to be caused by fatigue? Why might this number be an underestimation? Summarize what you learned in this course about the effects of sleep deprivation. Choose five effects, and for each, briefly explain how it could negatively effect driving. According to the article, what have Australian highway authorities done to combat boredom on empty stretches of highway? Distraction. What percentage of the 2020 traffic fatalities were estimated to be caused by distracted driving? Explain how stress may contribute to distracted driving. Explain how the design of cars may contribute to distracted driving. Give at least one example. Conclusion. What was the most surprising thing you learned in this article? Explain. Identify at least one concept you learned in this course that could apply to speed, impairment, fatigue, or distraction but was not discussed in the article. Briefly describe the concept, and then explain how it could be a contributor to car crashes. Reference Pappas, S. (2022, June). Improving traffic safety. Monitor on Psychology, 53(4), 46–55.

In 2017, I wrote a blog post about an activity designed to help students see how the number of drug overdose deaths have changed since 1968 using this interactive article from the New York Times. Carolyn Brown Kramer, via the Society for the Teaching of Psychology Facebook group, asked for updated drug overdose statistics. After having your students complete the activity from that initial blog post, provide students with the most current drug overdose death data presented below. The Centers for Disease Control and Prevention (CDC) provides a “Drug Overdose Deaths” statistics dashboard that is updated monthly based on the best available data. Keep in mind that the best available data are several months old. As I write this in March 2021, the latest data are for July 2020. Line graph Each data point in the line graph is a 12-month rolling total. For example, the number of drug overdose deaths reported for July 2020 are the number of drug overdose deaths that occurred between August 1, 2019 and July 31, 2020. The number of such deaths reported for June 2020 occurred between July 1, 2019 and June 30, 2020. Mouse over a data point to see the numbers. In the line graph you will see both “predicted” data (circles) and “reported” data (solid line). As they explain on the dashboard page, “Drug overdose deaths often require lengthy investigations, and death certificates may be initially filed with a manner of death ‘pending investigation’ and/or with a preliminary or unknown cause of death.” For “reported” data, the investigation is complete. The “predicted” data include deaths that are “pending investigation.” Both reported and predicted data will change as those investigations are completed. Ask your students to predict how the number of drug overdose deaths have changed in your state or District of Columbia, then change the jurisdiction to your location to show students the data. Map For easy visual comparisons between states/District of Columbia, the map displays data by location based on the number of drug overdose deaths for the most recent month for which data are available compared to the data from a year earlier. At the time of this writing, the comparison is between July 2019 and July 2020. The colors depict percentage change between those two months. North Dakota and North Carolina were the only two states with a decrease in the number of reported drug overdose deaths, down 2.3% and 1.7%, respectively. Alaska reported no change. All other states reported an increase. The District of Columbia had the biggest change during that time period with an increase of 56.8% in number of reported drug overdose deaths (308 to 483). Data Tables Sortable data tables of the line graph data and the map data are available directly below the map. Whatever you have selected as the jurisdiction for the line graph, those are the data that will be displayed in the first data table. A word of caution As you cover this very important topic with your students, remember that some—perhaps many—of your students has had someone they know die from a drug overdose. Or perhaps some of your students themselves came close to dying from a drug overdose. Always remembering that I’m talking about experiences my students have had helps me use language that is sensitive to the people behind the statistics.
