Prosopagnosia – face blindness – used to be thought a rare condition caused only by head trauma. We now know that is not that rare – 2% in the U.S., perhaps (Radden Keefe, 2016) – and that the cause can also be genetic. It also used to be thought that you were either normal or had prosopagnosia. We now know that facial recognition falls on a spectrum. If there is an end of the spectrum where faces are not recognized, it stands to reason that there is another end of the spectrum where faces are easily recognized. And there is research to back up that reasoning. They are called super-recognizers. For your students who are 18+, invite them to take the Cambridge Face Memory Test.  “The average score on this test is around 80% correct responses for adult participants.” The page gives 60% as the cut-off for potential face blindness. I came in at 68%. I should add that this test uses only Caucasian males.  Those of you familiar with the other-race effect may wonder about that. And you are right to wonder. They created a Chinese version and compared performance of participants of European descent and participants of Asian descent on both the Chinese version and the European version. As predicted by the other-race effect, participants of Asian descent did well on the Chinese version (average of 85% correct) but less well on the European version (average of 73% correct). Participants of European descent did well on the European version (76%), but less well on the Chinese version (average of 66%) (McKone, et.al., 2012). Developmental psychologists may be wondering how kids perform. A separate study with five- to twelve-year-olds found that kids develop better facial memory as they age. For example, five-year-olds got 66% correct, 8-year-olds got 76% correct, and 12-year-olds got 85% correct (Croydon, et.al., 2014).  While we’re in the middle of this topic, I might as well throw in how good crows are at recognizing human faces (see this article for more information). Don’t ever tick off a crow. What about those super-recognizers, though? How do they perform? Russell, Duchaine, and Nakayama (2009) found four people who were likely candidates for super-recognizer status. They tested them using the Cambridge Face Memory Test. Three of them earned perfect scores; one person missed one. And what are super-recognizers looking at when they look at a face? The eyes? Nope. The nose. It’s unlikely that that’s because the nose has some sort of special significance. It’s more likely that it’s because the nose is in the center of the face, allowing the super-recognizer to take in the whole face (Bobak & Bate, 2016). The forensically-minded may be wondering if the power of super-recognizers could be harnessed to fight crime. Yes, yes it can. New Scotland Yard created the Super-Recogniser Unit comprised of seven (as of August, 2016) police officers who are, well, super-recognizers. What do they do? Most commonly they look at closed circuit television (CCTV) video of crime suspects, and they look at photos of people who have been arrested. They are looking for a match. “It is not uncommon for a super-recognizer, out on the town with friends, to bolt off after spotting someone with an outstanding warrant.” One officer, James Rabbett, “since joining the team full time, six months ago… has made nearly six hundred identifications.” Yeah, but can’t computer recognition software do the same thing? Following riots in London, computers pegged one rioter. How did a super-recognizer do? He identified 190. Are they sometimes wrong? Yep. About 13% of the time. Their identifications alone are not enough to convict, though. Instead their identifications “help direct the investigation” (Radden Keefe, 2016). After sharing this information with students, ask students where else the power of super-recognizers could be put to good use. If students need a hint, point out that looking at ID and looking then looking at someone’s face requires some facial recognition power. Shout out to Ruth Frickle (Highline College) for posting the Radden Keefe New Yorker article to the STP Facebook page, an act that sent me down this research rabbit hole. References Bobak, A.

Did you ever wish you had access to a searchable database of twin correlations and trait heritability statistics? If not, once you see this, you will wonder why you hadn’t been looking for this kind of resource. Shout out to David Myers (Hope College) for pointing me toward MaTCH. Let’s take height as an example. From the first drop-down menu, select “ICF/ICD10 Subch” and then from the second drop-down menu, select “Height (297). The number in parentheses refers to the number of studies included in the displayed data. This is the first chart that is generated. If one identical (mz = monozygotic) twin is tall, there is a very good chance the other will be as well. If one is short, there is a very good chance the other will be as well. The correlation between being a twin and height is .91. The chart also gives correlations for just male identical twins (mzm = monozygotic male) and female identical twins (mzf = monozygotic female). If one fraternal (dz = dizygotic) twin is tall, there is a smaller chance the other will be as well – correlation of .54. Correlations are also given for all same-sex fraternal twins (dzss), just male fraternal twins (dzm), just female fraternal twins (dzf), and all other-sex fraternal twins (dos). Below the chart is this table. “Est.” is the estimated correlation based on the data from all of the studies included in the dataset. These are the correlations reported in the bar chart. “SE” is the standard error – the smaller the number, the more confident we are that the data reflect what’s true in the population. “Ntraits” are the number of studies in the dataset. “Npairs” are how many pairs of twins were included. While the correlations are interesting – and can certainly provide you with some interesting correlations when covering research methods – the real interesting stuff in this website comes from the last chart. This is where we get the “Reported ACE” – the heritability data. ACE is a model used among heritability researchers. A is additive genetics (the contribution of genes), C is common environment (the contribution of experiencing a shared environment), and E is [unique] environment (the contribution of our own, individual experiences). Before we get into the data, let’s a do a quick refresher of what heritability – and the ACE model – is. Within a population, people vary, say, in height. In the United States, the average height for adult females is about 5’ 4” (Onion, 2016). Some women are taller than that average, while others are shorter. It’s that difference between the shortest and the tallest – the variance – that ACE addresses. Let’s look at the “Reported ACE” chart for height. Picture this. Let’s say that we got all of the women in the United States together in one space. We measured each of their heights. A few would be less than 3 feet tall and a few would be more than 8 feet tall. Most would probably fall between 4’ 6” and 6’ 3 inches. The ACE model addresses where those differences in height come from. We are all going to be of some height just by virtue of being born. But what explains the differences in height among us? This article provides a nice explanation of heritability (Adam, 2012). “h2_all” is the heritability estimate for everybody based on the twin data. This means that 63% of the difference (the variability) in the height among all of us is due to genetics. “c2_all” is the estimate of the role played by a shared, common environment. This means that 30% of the difference in the height among all of us is due to a shared environment. Those two variables, genetics and common environment, together account for 93% (63% plus 30%) of the differences in our heights. The remaining 7%? That’s due to our unique environmental experiences. Please note that this says nothing about our own individual height. As a 5’ 4” female from the United States, this does NOT mean that 63% of my height is due to genetics. These numbers are only meaningful in explaining the differences in our heights across a population. To emphasize how population-driven heritability estimates are, on MaTCH’s left navigation menu, click on “Country.” Here you will see the data for height (if you were looking at the height variable) broken down by country. The ‘r’s are the correlations. Scroll to the right to see the heritability and common environment numbers. Canada, for example, shows 34% heritability for height and 60% for common environment, leaving 6% for unique environment. These numbers are very different from, say, the data for the United States. The U.S. shows 85% for heritability and 8% for common environment, leaving 7% for unique environment. Why might this be? Maybe Canadians are more genetically alike than are people in the U.S., thus differences amongst Canadians in their height must be more due to environment. Or maybe there just isn’t enough Canadian data. In the second column of that table, we see that three studies were used to calculate the Canadian estimates whereas 29 studies were used to calculate the U.S. data. There is much data here to explore. Before you dive too deeply into this website, watch this 15-minute tutorial video. Video Link : 1731 If you want to tackle this with your Intro Psych students, perhaps wherever you cover genetics, send your students to the MaTCH website to choose a psychologically relevant trait. Give your students a template like this to complete. The correlation for identical twins (mzall) on ______________ (enter trait name) is ________ (first line in the blue chart). The correlation for fraternal twins (dzall) on ______________ (enter trait name) is ________ (fourth line in the blue chart). The differences in  ______________ (enter trait name) within a population are _____% (h2_all) due to genetics, _____% (c2_all) due to a shared environment, and _____% (100 minus h2_all minus c2_all) due to a unique environment.   If students can’t find the trait they are interested in from the drop-down menu, they can click on “Find my Trait” in the top navigation bar. Searching on “intelligence” for example, tells us that that trait is lumped under “Higher-Level Cognitive Functions”. References Adam, G. (2012, September 6). What is heritability?

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

Originally posted on June 26, 2014. 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

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.

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).

Whatever words researchers have chosen to use to refer to people with intellectual disability have been turned into pop culture insults, such as idiot, imbecile, and moron. In more recent decades when researchers favored the term mentally retarded, “retard” became the preferred insult. In fact I heard a student utter this in my class just a couple weeks ago. The student, I am sure, did not intend to offend an entire group of people. Instead, she was using a word she learned to be a good stand-in for asinine. Personally, I’d like to see asinine make a comeback. It’s a good word. It nicely calls out asinine behavior without denigrating a group of people. In the fall of 2012, after a presidential debate, Ann Coulter tweeted “I highly approve of Romney’s decision to be kind and gentle to the retard” (https://twitter.com/AnnCoulter/status/260581147493412865). On the Special Olympics website the next day John Franklin Stephens responded. “I’m a 30 year old man with Down syndrome who has struggled with the public’s perception that an intellectual disability means that I am dumb and shallow. I am not either of those things, but I do process information more slowly than the rest of you. In fact it has taken me all day to figure out how to respond to your use of the R-word last night.” His time was well-spent; he wrote a beautiful, well-crafted response. He closed with this, “Well, Ms. Coulter, you, and society, need to learn that being compared to people like me should be considered a badge of honor. No one overcomes more than we do and still loves life so much. Come join us someday at Special Olympics. See if you can walk away with your heart unchanged.” He signed it, “A friend you haven’t made yet.” More recently, a New York Times article (May 7, 2016) reflected on the use of the term intellectual disability, the favored term for the last decade. The article provides a nice historical summary of both the language used and how people with intellectual disabilities were treated. Michael Wehmeyer (director of the University of Kansas Beach Center on Disability) notes that intellectual disability is “the first term that doesn’t refer to the condition as a defective mental process – slow, weak, feeble… Intellectual disability conveys that it is not a problem within a person, but a lack of fit between that person’s capacities and the demands of the environment in which the person is functioning.” Although he personally prefers cognitive disability (and so do I, not that I really get to have an opinion on the matter). It is difficult to imagine how “intellectual disability” could be twisted into an insult. While those who think of such things work on that, the rest of us can work on helping our students understand how offensive it is to casually toss around the word retarded as an insult. This is an easy topic to tackle when covering development, intelligence, or perhaps even better, stereotyping and prejudice. We seem to have largely moved past “that’s so gay” as an insult. We can do the same with “that’s so retarded.” Signed, The niece of a woman with an intellectual disability ... View more

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
