Originally posted on May 7, 2014. The Iran and Afghanistan Wars introduced a new and troubling picture on the relationship between traumatic brain injury and mental health. Multiple deployments exposed soldiers to more frequent risks. New combat gear helped them survive blasts. Suicide, substance use, and strained relationships often followed. But according to an Ontario study, we shouldn’t forget another vulnerable group: adolescents who have experienced at least one traumatic brain injury, defined as a head injury that caused either 5 minutes of unconsciousness or an overnight hospital stay. By comparison, the severity of the soldier injuries probably trumped those of the Toronto teens. Yet the two groups experienced similar consequences. In a study of almost 5000 Canadian students Grades 7-12, those who experienced a traumatic brain injury, compared those who didn’t, were nearly three times more likely to attempt suicide. The brain injured adolescents were also more likely to engage in antisocial behavior and experience anxiety and depression. Here is the most stunning statistic of all: roughly 20% of Ontario adolescents have a lifetime history of traumatic brain injury. Part of this makes sense. Think back to when you were a teenager. Perhaps you skateboarded, played soccer, hockey, football, or roughhoused with your siblings. Learning how to drive, you might have been injured in a car accident. Our teenage years are often filled with risk because the teenage brain is hypersensitive to reward. (To watch some videos of a true genius on the topic of the teenage brain, click here). Yet the drive for reward can come at the greatest cost of all. By risking their bodies, adolescents risk their brains. And when that piece of equipment doesn’t run on all cylinders, life becomes more of a slog than a sweet dream. The next time you think of brain injury, think of those who put themselves in harm’s way. For some of us, risk if part of our job. For others, it’s part of our development. For all of us, it’s time to reconsider who needs help.      ... View more

Originally posted on July 22, 2014. Social support can take many forms. A helpful tweet, the annual Facebook birthday barrage of well wishes, and long conversations with friends and family can put things in perspective and reduce our stress. But, according to recent research from Renison University, Wilfrid Laurier University, and the University of Waterloo, these acts of kindness backfire when interacting with people who have low self-esteem. People with low self-esteem have social support preferences that often put them on a collision course with their friends and family. They desire information that validates their negative self-feelings. When their friends offer positive feedback, people with low self-esteem don’t accept it. This aversion to positivity causes low self-esteem spillover: Their friends begin to feel bad about themselves, too. What is the moral of the story? Find someone who has a similar self-concept as you do. Birds of a feather should often flock together. Although it might be hard to imagine wanting information that validates our negative self-feelings, it is unwise to force people to enjoy something they dislike. Knowing yourself and what you like is the first step in building a successful relationship. The next step is finding someone who shares your preferences, no matter how sunny or gloomy they might be. ... View more

The development of adolescent impulse control lags sensation-seeking.  That’s the bottom line result of Laurence Steinberg’s report from surveys of more than 7000 American 12- to 24-year-olds, as part of the National Longitudinal Study of Youth and Children and Young Adults. Sensation-seeking behaviors peak in the mid teens, with impulse control developing more slowly as frontal lobes mature. These trends fit nicely with data from longitudinal studies that, after following lives through time, find that most people become more conscientious, stable, agreeable, and self-confident in the years after adolescence.  The encouraging message for parents of 15-year-olds: you may be pleasantly surprised at your more self-controlled 25-year-old offspring to come.  And for courts, says Steinberg, the brain development and behavioral data together should inform decisions about the criminal sentencing of juveniles. ...

Originally posted on December 2, 2014. As I explain in a recent APS Observer essay (here), my short list of psychology’s greatest research programs includes the 250+ scientific publications that have followed Scottish lives from childhood to later life.  The studies began with all Scottish 11-year-olds taking intelligence tests in 1932 and in 1947 (the results of which Ian Deary and his team discovered many years later).  After meeting Deary at an Edinburgh conference in 2006 and hearing him describe his tracking these lives through time, I have followed his team’s reports of their cognitive and physical well-being with great fascination. Last April, some 400 alums of the testing—now 93 or 78 years old (including those shown with Deary below)—gathered at the Church of Scotland’s Assembly Hall in Edinburgh, where Deary regaled them with the fruits of their participation. One of his conclusions, as reported by the October 31st Science​, is that “participants’ scores at age 11 can predict about 50% of the variance in their IQs at age 77.” I invited Professor Deary to contribute some PowerPoint slides of his studies for use by teachers of psychology.  He generously agreed, and they may be found here.

Originally posted on July 21, 2015. From the daily information stream that flows across my desk or up my computer screen, here is a recent news flash: Money matters more to midlife folks than to those younger and older. There’s a modest correlation between income and life satisfaction, note Felix Cheung and Richard Lucas. Their analyses of three national data pools found that correlation to be strongest for people in their 30s to 50s. It makes sense, they reflect: midlife adults have more financial responsibility for their children and sometimes their aging parents. College students and older adults more often enjoy financial support apart from income. ... View more

Originally posted on August 4, 2015. From the daily information stream that flows across my desk or up my computer screen, here is a recent news flash: With age we mellow. A European research team led by Annette Brose sampled people’s emotions across 100 days. One finding: young adults’ self-reported emotions were more variable. This reminds me of Mihaly Csikszentmihalyi and Randy Larson’s long-ago sampling, using pagers, of people’s experience. Young teenagers, they found, typically descend from elation or ascend from gloom in less than an hour. Adult moods are less extreme but more enduring. Having survived past sufferings and enjoyed past thrills, mature people look beyond the moment. ... View more

Theresa Wadkins (University of Nebraska – Kearney) has a quick, but powerful way to demonstrate schemas in action. On the day she covers schemas, Wadkins walks into class, approaches a student, and asks, “How are you? Are you having a good day?” After the student responds, sometimes in befuddlement, she returns to the front of the room and begins her lecture. A few minutes later, she returns to the student and asks, “How is everything?” Again, the student responds, even more perplexed. And then back to the lecture. For the third and final time, she returns to the same student and asks, “Can I get you anything?” Wadkins then explains to her students that we have different schemas for what happens in a classroom and what happens in a restaurant. While being asked such questions is peculiar for a classroom, we would be put off if we weren’t asked these very same questions by a server in a restaurant. If you’d like to expand on this activity, ask students – in small groups or through an online discussion board – to identify the schema characteristics of what happens when a customer visits a sit-down restaurant and the schema characteristics of what happens when a customer visits a fast-food restaurant. Invite students to share the characteristics of each that they generated. Summarize the responses into a coherent schema for each type of restaurant. Ask students to reflect – in small groups, through an online discussion board, or as a written assignment – on what would happen if they had no schema for a sit-down restaurant when they walked into one. Or if they had no schema for a fast-food restaurant when they walked into one. Or if they walked into one type of restaurant with the schema for the other type of restaurant in mind. For added discussion or writing assignment, invite students to identify times when a schema they had did not match the situation. ... View more

If you make candy bars and sell them through vending machines, you can use operant conditioning principles to get people to do all sort of things. In this case, Nestlé, the maker of Kit Kat bars in Brazil, put special vending machines on two different college campuses in the same Brazilian city. The machines streamed video to each other. Players stepped up to each machine and pressed play (“jogar” in Portuguese). The goal? To win a staring contest. The winner earned a Kit Kat Chunky chocolate bar. Video Link : 1628 Bonus: If you’d like to expand your coverage of schemas to talk about differences in food preferences around the world, tell your students about the phenomenon that is Kit Kat, the most popular candy, in Japan. Ask your students to guess how many flavors of Kit Kat there are in Japan. The answer: almost 300 (Goldman, 2016). Some of the flavors: grilled potato, cherry blossom, soybean, blueberry cheesecake, chocobanana, white peach, green tea, pumpkin, apple, mango, lemon, red bean paste, apple vinegar, pineapple, kiwi, cappuccino, jasmine tea (The weird and wacky…, n.d.). Want to try out some of these flavors yourself? You can order some here. Why is Kit Kat so popular in Japan? One factor is probably because its name is similar to the Japanese phrase kitto katsu – good luck (literally, surely win) (Goldman, 2016). Goldman, R. (2016, May 13).

Patty Duke, who portrayed a young Helen Keller in The Miracle Worker in the play and later in the movie, died on March 29, 2016. Her obituary in The Telegraph discussed her less-than-pleasant relationship with her guardians. For example, “For 18 months before the audition for the Broadway production of The Miracle Worker, the Rosses spent some time each day treating their protegée as if she were deaf and blind, banging pots and pans behind her until she no longer reacted and making her do household chores blindfold.” This is quite an example of habituation. “[S]ome time each day” for a year and a half Duke’s guardians made sudden, loud noises. Sure enough, she eventually would not respond to those sounds. If you have the time, you can do a quick classroom demonstration. Start the demonstration by asking students to write down something, like the names of five friends. As students look down to write, slam a book on a table. Ask students, “Raise your hand if you jumped.” Briefly tell your students who Helen Keller was and show a short clip from The Miracle Worker. Now ask your students to consider the challenges faced by Patty Duke playing someone who is both deaf and blind. “If you were Patty Duke, what could you do to prepare for this role so that you wouldn’t respond to sudden, loud noises?” After students share their ideas, reveal how Duke’s guardians prepared her. ...

The coverage of epigenetics in Intro Psych textbooks appears to be slowly on the rise. And with good reason. If you're not familiar with epigenetics, this 9-minute student-friendly video is a nice introduction Video Link : 1576 For a more scholarly introduction to epigenetics, this 2016 article from Child Development will get you up to speed. In Intro Psych, your textbook may give an overview of the topic wherever it covers genetics and revisit epigenetics again during coverage of psychology disorders. Research is stacking up. Our experiences influence the turning on and off of genes that are linked to psychological disorders. For example, "Exposure to stressful or traumatic life events, especially early in life (early life stress (ELS)), is one of the strongest risk factors for a number of psychiatric disorders, ranging from post-traumatic stress disorder (PTSD) over depression to bipolar disorder and schizophrenia. Over the past decade, an ever growing body of evidence indicates that exposure to stressful life events can lead to long lasting changes in a number of systems including the endocrine system, the immune system and brain structure and function" (Provencal & Binder, 2015). If a cause of psychological disorders is related to epigenetics, the effectiveness of treatments may also reside in epigenetics. Electroconvulsive therapy, for example, may alter epigenetic tags (Jong, et.al., 2014). Psychiatric drugs may also work this way (Boks, et.al., 2012). For Intro Psych, the specifics of epigenetics is probably not that important, but a broad overview and the implications of the research are certainly worth the time. References Boks, M.

I admit it. Development is not my favorite Intro Psych chapter. That makes me extra thankful to Intro Psych textbook authors who put one of my favorite cognitive psych concepts in this chapter. Understanding schemas can help students get inside their own heads and realize that how they think the world works may not actually be how the world works. Also, and I have no evidence for this, understanding schemas may help students be more patient with others. “Oh! I can see what schema you’re working from. It’s wrong, but I can see it.” The website Not Always Right gives those working in customer service an opportunity to share some of their more frustrating or baffling interactions with customers. Not Always Learning does the same for education with both those working in education and students sharing their experiences. We have schemas for social interactions. We carry a set of assumptions for how different social interactions will go. Probably every barista has greeted a customer with “Good morning. How are you?” only to have the customer respond with “I’ll have a tall coffee” (I’m Feeling Pretty Coffee Myself Too). The customer’s schema for barista-interaction has the barista asking, “What can I get you?” (or, more  and more frequently, what Starbucks has brought us, “What can I get started for you?”), so that is the question that is answered. In a noisy coffee shop with a sleep-deprived and not-yet-caffeinated customer, the actual question, “How are you?” may not have even been heard, and if it was, not processed. The customer relies on his or her schema to drive the interaction. We have schemas for how technology works. When a customer purchased a portable gaming system, the customer assumed that the system came with its own ability to connect to the Internet (Wireless, Clueless, Hopeless, Part 24). Through the interaction with the salesperson at the video game store, it becomes clear that the customer doesn’t have an accurate e schema for how the Internet works. While we’re not privy to the customer’s Internet experience, it’s reasonable to assume that the customer has a smartphone that doesn’t require anything special to connect to the Internet. It just does it. The customer’s schema for “connecting to the Internet” may include the idea that small electronics all come with an automatic ability to access the Internet. We have schemas for something as simple as how to make copies. A library patron has something in print, perhaps pages from a book, and wants a physical copy of it (Sloppy Copy). For those of us who spent too much of our time in college and grad school in front of copiers, our schemas for how to get a physical copy of book pages includes taking the book to the copier and, well, copying it. For those who grew up in a digital age, they are very familiar with printing, but probably not so much with copying. This patron was trying to figure out how to scan the book and then print it, not recognizing that photocopying directly was a possibility. And then try explaining mimeographs. As an out-of-class assignment or an in-class small group activity, send students to these websites, and ask them to find other examples of schemas gone awry. ... View more

Last week I wrote about how it is I came to wear psychology-related t-shirts to my Intro Psych classes. That post included nine t-shirts. [Read that post.] This week I have ten to share. Vision – Childish Side of the Moon This is a pretty straight-forward illustration of how white is the presence of all wavelengths of light. And the Pink Floyd fans in your class will enjoy the reference. Sleep – Big Fan I hammer pretty hard the importance of sleep. Too many students think that staying up all night studying is a good idea, and I present the landslide of evidence that says it’s not. In case they miss my message, perhaps due to sleep deprivation, this t-shirt drives home the point. Sleep – Counting Sheep If I’m feeling more whimsical, I will go with this shirt depicting counting sheep – on a calculator, on “fingers,” on an abacus. Psychoanalysis – Devil and angel bunnies If you talk about the id, ego, and superego, this shirt is a must. Wear a shirt over top, like a denim shirt or a light fleece. As you describe the conflict between the id and the superego, if you’re lucky, a student will say something like, “Oh! Like the devil and angel on your shoulders!” That’s your cue to remove your outer layer, revealing the devil and angel bunnies on your shoulders. Research methods – Science of the Lambs When introducing research methods in Intro, I sometimes talk about how people think that what determines what is a science and what is not are the apparatuses that are used. “If there are flasks and Bunsen burners, then it is science.” If class time allows, I ask students to consider that question: What makes a science a science? This makes for a nice think (on your own for a minute or two), pair (talk with the person next to you for a minute or two), share (ask for volunteers to share their responses) activity. Personality – Introverting When covering the Big Five personality traits, I use this shirt to come out as an introvert. The best metaphor I have heard for introversion and extraversion says that which way you lean is determined by what recharges your batteries most of the time. If your batteries recharge when you are with people, you are more extraverted. If your batteries recharge when you are alone, you are more introverted (see this blog post for example). The message in this shirt is “back off; I’m recharging.” Sensation — Hello? Can anybody hear me? I use this shirt to introduce the idea that sound and color only exist in our brains. Sound waves and light waves exist outside of us, but what we describe as sound and what we describe as color don’t. They are sensations created by our brains, a conversion of those waves into something we can experience. Development – Donkey Kong and Mario  This shirt’s a nod to the gamers in your class. If you’d like to use this shirt for discussion, ask students questions like: Given that Mario is walking, how old would you guess he is? [2-ish] What reflex is Donkey Kong exhibiting with the baby bottle? [grasping] Years later, do you expect them to remember this event? Why? [nope, infantile amnesia] You can also reprise this shirt for the social psych chapter. What are some ways in which Donkey Kong and Mario could work to resolve their conflict? [e.g., superordinate goals].            Optimism/pessimism – Which glass are you? When covering optimists and pessimists, this shirt provides an opportunity to introduce students to some other -ists, such as utopists and surrealists. Be prepared to explain some of these; students will ask. Final exam day – Pencils Since students are required to bring a Number 2 pencil to take the final exam, this handy shirt depicts pencil numbers 1 through 12. ... View more

As a psychology instructor it is clear to you the myriad ways in which psychology can be used to both understand social issues and speak to solutions. In fact, the APA Guidelines for the Major (2013; see below) encourages us to help our students see the same. Debra Mashek (2016) suggests a few assignments that provide our students opportunities to connect psychology with today’s social issues. Integrative essay The instructor chooses three articles (interesting, nifty methodology, and not too difficult for students to understand – but on the surface may not have anything obviously to do with each other), and assigns one of those articles to each student, i.e. 1/3 of the class gets article A, 1/3 gets article B, and 1/3 gets article C. Each student writes a one-page summary of their assigned article and brings that with them to class. The class breaks up into groups of three, where the groups are composed of students who have all read different articles. In a jigsaw classroom format, the students tell the others in their three-person group about their article. Students then “articulate an applied question that invites application of ideas from all the articles.” Each 3-person group then co-authors a short paper (two to three pages) that identifies their applied question and how each of the three articles speak to that question. Persuasion research activity Right after Hurricane Katrina, Mashek decided she wanted her Intro Psych students to experience psychological research firsthand while also contributing to the relief effort. Mashek gave a brief lecture on foot-in-the-door, door-in-the-face, and reciprocity. She randomly assigned ¼ of students to foot-in-the-door, ¼ to door-in-the-face, ¼ reciprocity (she gave these students lollipops to hand to people before asking for a donation), and ¼ to a command condition (“give money”). During that same class period students were sent out in pairs to different areas of campus to return an hour later. Thirty-five students collected $600. Students reported a greater connection to the victims of Katrina after they returned than they reported before they left. Mashek used this experience as a leaping off point for discussing research methodology in the next class session. Current headline classroom discussion Pick a current headline. Break students into small groups, perhaps as an end of class activity, and give them one or two discussion questions based on the current chapter you are covering that are relevant to the headline. For example, if you are covering the social psychology chapter in Intro Psych, give students this headline from the January 9, 2016 New York Times: “Gov. Paul LePage of Maine Says Racial Comment Was a ‘Slip-Up’.” This is a short article, so you could ask students to read the article itself. Sample discussion questions: (1) What evidence is there of ingroup bias? (2) Do Gov. LePage’s comments illustrate stereotyping, prejudice, and/or discrimination? Explain. If time allows, student groups can report out in class. Alternatively, this could be a group writing assignment or a scribe for the group could post a summary of the group’s responses to a class discussion board. Students will gain an appreciation of the scope of psychology and how it is relevant to today’s social issues. This activity throughout the course should help students, after the course, to continue to see psychology at play. The APA Guidelines for the Major (2013) include these indicators related to social issues: 1.3A Articulate how psychological principles can be used to explain social issues, address pressing societal needs, and inform public policy 3.3c Explain how psychology can promote civic, social, and global outcomes that benefit others 3.3C Pursue personal opportunities to promote civic, social, and global outcomes that benefit the community. 3.3d Describe psychology-related issues of global concern (e.g., poverty, health, migration, human rights, rights of children, international conflict, sustainability) 3.3D Consider the potential effects of psychology-based interventions on issues of global concern American Psychological Association.

This piece was originally published on April 17th, 2008   Throughout the world, boys and girls prefer to play with different types of toys. Boys typically like to play with cars and trucks, while girls typically choose to play with dolls. Why is this? A traditional sociological explanation is that boys and girls are socialized and encouraged to play with different types of toys by theirparents, peers, and the “society.” Growing scientific evidence suggests, however, that boys’ and girls’ toy preferences may have a biological origin. In 2002, Gerianne M. Alexander of Texas A&M University and Melissa Hines of City University in London stunned the scientific world by showing that vervet monkeys showed the same sex-typical toy preferences as humans. In an incredibly ingenious study, published in Evolution and Human Behavior, Alexander and Hines gave two stereotypically masculine toys (a ball and a police car), two stereotypically feminine toys (a soft doll and a cooking pot), and two neutral toys (a picture book and a stuffed dog) to 44 male and 44 female vervet monkeys. They then assessed the monkeys’ preference for each toy by measuring how much time they spent with each. Their data demonstrated that male vervet monkeys showed significantly greater interest in the masculine toys, and the female vervet monkeys showed significantly greater interest in the feminine toys. The two sexes did not differ in their preference for the neutral toys. Alexander and Hines’s article contains a wonderful picture (reproduced here in full living color, courtesy of Gerianne M. Alexander) of a female vervet monkey conducting an anogenital inspection (examining the genital area of the doll in an attempt to determine whether it is male or female), as a girl might, and a male vervet monkey pushing the police car back and forth, as a boy might. If children’s toy preferences were largely formed by gender socialization, as traditional sociologists claim, in which their parents give “gender-appropriate” toys to boys and girls, how can these male and female vervet monkeys have the same preferences as boys and girls? They were never socialized by humans, and they had never seen these toys before in their lives. Yet, not only did male and female vervet monkeys show the identical sex preference for toys, but how they played with these toys was also identical to how boys and girls might. As stunningly ingenious and spectacular Alexander and Hines's initial study was, it stood alone in the scientific literature for a while. All new scientific discoveries must be replicated to make sure that the findings are both genuine and generalizable. Well, it took the field six years, but the original findings have now been replicated. In a forthcoming article in Hormones and Behavior, Janice M. Hassett, Erin R. Siebert, and Kim Wallen, of Emory University, replicate the sex preferences in toys among members of another primate species (rhesus monkeys). Their study shows that, when given a choice between stereotypically male “wheeled toys” (such as a wagon, a truck, and a car) and stereotypically female “plush toys” (such as Winnie the Pooh, Raggedy Ann, and a koala bear hand puppet), male rhesus monkeys show strong and significant preference for the masculine toys. Female rhesus monkeys show preference for the feminine toys, but the difference in their preference is not statistically significant. We do not yet know exactly why males of different primate species prefer wheeled toys and other vehicles, or why females of different primate species prefer plush toys and other dolls (except for their vague resemblance to babies, for which females are evolutionarily designed to care). However, it is becoming less and less likely that “gender socialization” is the reason why boys and girls prefer different toys, and more and more likely that there are some genetic, hormonal, and other biological reasons for the observed sex differences in toy preference. ...
