As if cell phone use in cars isn’t bad enough, car manufacturers are building distractions into our automobiles, which I affectionately call Built-in Automotive Driving Distraction Systems TM . Automakers now include more options to allow drivers to use social media, email and text. The technology is also becoming more complicated to use. Cars used to have a few buttons and knobs. Some vehicles now have as many as 50 buttons on the steering wheel and dashboard that are multi-functional. There are touch screens, voice commands, writing pads, heads-up displays on windshields and mirrors and 3-D computer-generated images (Lowy, 2017). In an attempt to save lives, I have been hammering pretty hard on our inability to multi-task in my Intro Psych course. While this topic comes up in greater detail when I cover consciousness, I also embed examples of attention research in my coverage of research methods. Correlation example After I introduce the concept of correlations, I give my students 5 correlations, and ask them to identify the correlation as positive, negative, or no correlation. One of those correlations comes from a 2009 Stanford study reported by NBC News: people who multitask the most are the worst at it (“memory, ability to switch from one task to another, and being able to focus on a task”) (“Multitaskers, pay attention -- if you can,” 2009). Experiment example In talking about experimental design, I discuss David Strayer’s driving simulation research at the University of Utah. His lab’s research is easy for students to understand and the results carry a punch. I give this description to my students and ask them to identify the independent variable and the dependent variables. In an experiment, "[p]articipants drove in a simulator while either talking or not talking on a hands-free cell phone." Those who were talking on a cell phone made more driving errors, such as swerving off the road or into the wrong lane, running a stoplight or stop sign, not stopping for a pedestrian in a crosswalk, than those who were not talking on a cell phone. Even more interestingly, those who were talking on a cellphone rated their driving in the simulator as safer as compared to those who weren't talking on a cellphone. In other words, those talking on the cellphone were less likely to be aware of the driving errors they were making (Sanbonmatsu, Strayer, Biondi, Behrends, & Moore, 2016).   Class demo When Yana Weinstein of LearningScientists.org posted a link to a blog she wrote on a task switching demo (Weinstein, 2017) to the Society for the Teaching of Psychology Facebook page, I thought, “Now this is what my research methods lecture was missing!” I encourage you to read Weinstein’s original demo once you’re done reading mine.   I randomly divided my class into two groups. To do that I used a random team generator for Excel, but use whatever system you’d like. Weinstein does this demo with a within subjects design which, frankly, makes more sense than my between subjects design, but in my defense I’m also using this demo to help students understand the value of random assignment.   One group of students recited numbers and letters sequentially (1 to 10 and then A to J). The other group recited them interleaved (1 A 2 B 3 C, etc.). In your instructions, be clear that students cannot write down the numbers/letters and just read them. That’s a different task! Students worked in small groups. While one student recited, another student timed them with a cellphone stopwatch app. (You don’t have to know anything about cellphone stopwatch apps. Your students can handle it.) I didn’t bother dividing students into groups by task. In one group, there might have been three students who recited sequentially and a fourth student who recited interleaved. I asked students to write down their times, and then I came around to each group and asked for those times. I just wrote the times on a piece of paper, and displayed the results using a doc camera. Almost everyone in the sequential condition recited the numbers/letters in under 6 seconds. Almost everyone in the interleaved condition took over 13 seconds. In addition to talking about the independent variable (and experimental and control conditions) and the dependent variable, we talked about the value of random assignment. I had no idea who could do these tasks quickly or slowly. If 20% of them could do these tasks quickly, then random assignment would likely create two groups where the percentage of fast-task participants would be the same in each group. Is it possible that all of the fast-task participants ended up in the sequential task condition? Yep. And that’s one reason replication is important. Oh. And when you’re studying or writing a paper, students, this is why you should keep your phone on silent and out of sight. If you keep looking at your phone for social media or text notifications, it’s going to take you a lot longer to finish your studying or finish writing your paper. Perhaps even twice as long. And driving? As you switch back and forth from driving to phone (or from driving to Built-in Automotive Driving Distraction Systems TM ), it’s not going to take you twice as long to get to your destination. You’re traveling at the same speed, but you’re working with half the attention. That increases the chances that you will not get to your destination at all.   A lot of what we cover in Intro Psych is important to the quality of students’ lives. Helping students see our inability to multitask is important in helping our students – and the people they are near them when they drive – stay alive.   References Lowy, J. (2017, October 5).

We humans have an overwhelming fear of death. That’s the core assumption of “terror management theory.” It presumes that, when confronted with reminders of our mortality, we display self-protective emotional and cognitive responses. Made to think about dying, we self-defensively cling tightly to our worldviews and prejudices.   On the assumption that dying is terrifying—that death is the great enemy to be avoided at all costs—medicine devotes enormous resources to avoiding death, even to extending life by inches. And should we be surprised? I love being alive and hope to have miles of purposeful life to go before I sleep.   So, do we have the worst of life yet to come? Are we right to view life’s end with despair?   Two psychological science literatures reassure us:   The first: The stability of well-being. Across the life span, people mostly report being satisfied and happy with their lives. Subjective well-being does not plummet in the post-65 years. In later life, stresses also become fewer and life becomes less of an emotional roller coaster.   The second: Human resilience. More than most people suppose, we humans adapt to change. Good events—even a lottery win—elate us for a time, but then we adapt and our normal mix of emotions returns. Bad events—even becoming paralyzed in an accident—devastate us, but only for a while. Both pleasures and tragedies have a surprisingly short half-life. Facing my increasing deafness, the reality of resilience is reassuring.   And now comes a third striking finding: Dying is less traumatic than people suppose. Amelia Goranson and her colleagues examined      blog posts of terminally ill cancer and ALS patients, and      last words of death row inmates before their execution. Others, asked to simulate those posts and words, overly expressed messages filled with despair, anger, and anxiety. More than expected—and increasingly as death approached—the actual words of the dying expressed social connection, love, meaning, and faith.   Goranson and her colleagues presume (though it remains to be shown) that the same acceptance and positivity will be exhibited by those dying at the more expected time on the social clock—very late in life, when people (despite stereotypes of grumpy old men) tend to focus on the positive. Thus, conclude the researchers, “death is more positive than people expect: Meeting the grim reaper may not be as grim as it seems.” ... View more

As y’all know, females and males are mostly alike—in overall intelligence, in physiology, and in how we perceive, learn, and remember. All but one of our chromosomes is unisex. Yet gender differences in mating, relating, and suffering are what grab our attention. And none more than the amazingly widespread and reliably observed gender difference in vulnerability to depression.   In this new Psychological Bulletin meta-analysis, Rachel Salk, Janet Hyde, and Lyn Abramson digest studies of gender and depression involving nearly 2 million people in 90 countries. The overall finding—that women are nearly twice as likely as men to be depressed—is what textbooks have reported. What’s more noteworthy and newsworthy, in addition to the universality of women’s greater risk of depression, is the even larger risk for girls during adolescence. As their figure, below, shows, the gender difference in major depression begins early—by puberty—and peaks in early adolescence. The take-home lesson: For many girls, being 13- to 15-years-old can be a tough time of life. ... View more

As is plain to see, Americans are living in a politically polarized era. “Partisan animus is at an all-time high,” reports Stanford political scientist Shanto Iyengar. Nearly 6 in 10 Republicans and Democrats have “very unfavorable” opinions of the other party, and most engaged party adherents feel “angry” about the other party. “Partisans discriminate against opposing partisans, doing so to a degree that exceeds discrimination based on race,” conclude Iyengar and Sean Westwood from their study of “Fear and Loathing Across Party Lines.” If you are American, do you find yourself disdaining those with opposing political views more than those in any other social category (including race, gender, and sexual orientation)? Would you want your child to marry someone aligned with the other party?   Americans on both sides also tend to see the other side (compared to their own) as more extreme in its ideology. It’s hard not to agree that those in the other party seem more extreme and biased.   But are they? Multiple research teams—at Tillburg University, the University of Florida, the College of New Jersey, and the University of California, Irvine—have found similar bias and willingness to discriminate among both conservatives and liberals. At the latter university, a forthcoming meta-analysis of 41 studies by Peter Ditto and his colleagues “found clear evidence of partisan bias in both liberals and conservatives, and at virtually identical levels.” When evidence supports our views, we find it cogent; when the same evidence contradicts our views, we fault it.   We can see equal opportunity bias in opinion polls. Last December, 67 percent of Trump supporters said that unemployment had increased during the progressive Obama years. (It actually declined from 8 to less than 5 percent.) And at the end of the conservative Reagan presidency, more than half of self-identified strong Democrats believed inflation had risen under Reagan. Only 8 percent thought it had substantially dropped—as it did, from 13 to 4 percent.   Peter Ditto’s conclusion: “Bias is bipartisan.” This humbling finding is a reminder to us all of how easy it is (paraphrasing Jesus) to “see the speck in your neighbor’s eye” while not noticing the sometimes bigger speck in our own. ...

In an earlier blog post, I reported on an analysis of 34,000+ Americans’ health interviews with the Centers for Disease Control and Prevention (CDC). To my astonishment, Megan Traffanstedt, Sheila Mehta, and Steven LoBello found no evidence that depression rises in wintertime, or that wintertime depression is greater in higher latitudes, in cloudy rather than sunny communities, or on cloudy days. Moreover, they reported, even the wintertime “dark period” in northern Norway and Iceland is unaccompanied by increased depression. Given the effectiveness of light therapy and the acceptance of major depressive disorder “with seasonal pattern” (DSM-5), I suspected that we have not heard the last word on this. Indeed, criticism (here and here) and rebuttals (here and here) have already appeared. Reading Seth Stephens-Davidowitz’s wonderful new book on big data mining inspired me to wonder if Google depression-related searches increase during wintertime. (To replicate the CDC result, I focused on the United States, though further replications with Canada and the UK yielded the same results.) First, I needed to confirm that Google Trends does reveal seasonally-related interests. Would searches for “basketball” surge in winter and peak during March Madness? Indeed, they do: We know that Google searches also reveal seasonal trends in physical illnesses. And sure enough, “flu” searches increase during the winter months. So, do searches for “depression” (mood-related) and “sad” similarly surge during wintertime? Nope, after a summer dip, they remain steady from mid-September through May: Ditto for Google entries for “I am depressed” and “I am sad.” My surprise at the disconfirmation of what I have taught—that wintertime depression is widespread—is like that experienced by my favorite detective, Agatha Christie’s Miss Marple: “It wasn’t what I expected. But facts are facts, and if one is proved to be wrong, one must just be humble about it and start again.”  [Note to teachers: you can generate these data in class, in real time, via Trends.Google.com.] ...

When biking we hardly notice the wind at our back, until we change directions and try riding against its force. Likewise, we may hardly notice the cultural winds that carry us until we step outside our boundaries. That’s one reason I benefit from the privilege of spending time each year visiting other countries. With each visit I am reminded that cultural norms—from how we meet and greet on the street to how we eat (fork in left hand or right? chopsticks?) to how we weave the social safety net—varies from my place to other places.   I write from Scotland, where my wife and I have frequently returned since taking a long-ago sabbatical year here at the University of St. Andrews. The last several days provide two examples of things many Americans take for granted, without realizing how culturally American they are.   Example #1: American supermarkets now have “foreign” food sections, where people can buy their favorite international items. Here in St. Andrews the largest foreign food section is “American.” And what foreign foods might you expect to find here (foods that, during our long-ago sabbatical were not available)?  In this American section one can find peanut butter, pancake syrup, canned pumpkin, baking soda, popcorn, sugary cereals, Oreos, Pop Tarts, and Twinkies. American foods! Example #2: The university’s library is a place of study for students from many countries, including cultures with squat toilets.  For me, the way to use a Western flush toilet seems obvious—it’s the way we do it (and I’m unbothered by what might seem gross to others—sitting on a toilet seat that has recently been sat on by others). But for some, a flush toilet needs explanation, just as I might need toileting instruction when visiting their cultures. Thus, this sign appears in the library bathrooms:    Our culture’s widely accepted behaviors, ideas, attitudes, values, and traditions may seem so natural and right to us that we fail to notice them as cultural. Experiencing other cultures’ ways of acting and thinking helps us to see what’s distinctive about our own. ... View more

As Nathan DeWall and I explain in Psychology, 11 th Edition, “Young infants lack object permanence—the awareness that objects continue to exist even when not perceived. By 8 months, infants begin exhibiting memory for things no longer seen.”   Given the early age at which infants display object permanence by looking for a hidden toy after a several second wait do developing primates also display a recall for objects no longer seen?   Research suggests that orangutans possess object permanence. . . . a point illustrated in this hilarious 38-second YouTube video pointed out to me by a Facebook engineer who happens to be one of my former students (and also one of my children ). ...

One of the great joys of attending conferences – in this case, the American Psychological Association convention – is the conversations with both new and old friends. This morning I had breakfast with Linda Woolf (Webster University; an old friend). She posed an interesting question, and before my first full cup of coffee, it was a little unfair. She noted that in our professional circles we frequently talk about psychology books we think psychology majors should read. She wondered what non-psychology books I’d recommend. That’s both an easy and a difficult question. It’s easy to find book that contain psychology, but difficult in deciding of all the books out there, what books I’d recommend. The two that came pretty quickly to mind were: The Boys in the Boat by Daniel Brown. About the University of Washington men’s crew who rowed in the 1936 Olympics in Berlin, the book gives us a healthy does of prejudice and perseverance. The Day the World Came to Town by Jim DeFede. On 9/11/2001 when the U.S. airspace closed, planes flying west across the Atlantic had to land in Canada. Thirty-eight of them landed in Gander, Newfoundland. Almost 7,000 visitors literally dropped into a town of 9,000 for five days. DeFede restores our faith in humanity with story after story of altruism. The musical Come From Away expands on those stories including coverage of prejudice, stress and coping, and ingroups/outgroups. (Honestly, the book may do the same, but it’s been years since I’ve read it.) After having had my full dose of coffee and a few more hours to reflect – and a chance to review my Goodreads books, here are some more non-psychology books recommended for psychology majors. Born a Crime by Trevor Noah Noah grew up in South African as “colored,” the South African term for half white/half black. His experience gets wrapped up in ingroups/outgroups, both sorting out what that means for him and being on the receiving end of other people’s assumptions about his group membership. The Warmth of Other Suns by Isabel Wilkerson Starting with World War I, African Americans started in earnest to move out of the south to points west and north. Spotlighting three people who left different places at different times for different locales, Wilkerson helps her readers understand the prejudice and discrimination that drove African Americans from the south to the different-looking prejudice and discrimination of their new homes. Sally Ride by Lynn Sherr Becoming the first U.S. woman in space had its challenges. More prejudice, discrimination, and perseverance in this book. When asked at a crew press conference in 1982 “Dr. Ride, apart from the obvious differences, how do you assess the differences in men and women astronauts?” Dr. Ride replied, “Aside from the obvious differences, I don’t think there are any.” Grandma Gatewood’s Walk by Ben Montgomery Emma Gatewood in 1955 and at the age of 67 decided to hike the 2,050-mile Appalachian Trail. Alone. This one will make students rethink their assumptions about gender and age. The Man Who Loved Only Numbers by Paul Hoffman Paul Erdös (pronounced air-dish) was a mathematical genius. But his biography is less about intelligence than it is about… well, it’s tough to describe. Being comfortable in your own skin, may be a good descriptor. Erdös was unapologetically Erdös. He couch-surfed from the home of one mathematician to another. His hosts didn’t know when he was coming until he appeared on their doorsteps, and they didn’t know when he was leaving until he left. He would ask strangers to tie his shoes. He offered cash to grad students to solve mathematical problems. The more difficult the problem, the greater the cash award. And Erdös published prolifically. Mathematicians have an Erdös number. If you published a paper with Erdös, your number is one. If you published with someone who published a paper with Erdös, your number is two. And so on. Addiction by Design by Natasha Dow Schüll [This book may not technically meet the requirements of the category given the amount of psychology in it.] This book contains everything you wanted to know about slot machines and then some. If you’re teaching that pushing buttons on a slot machine is an example of positive reinforcement, you’re wrong for a healthy chunk of slot machine users. Negative reinforcement would be a better characterization. Regular users of slot machines play not to win but play to enter the zone where they don’t have to think about problems at work, with their spouse, or with their kids. Winning just means being able to not think even longer. I managed to give you a list that is all nonfiction. Please share your recommendations in the comments – and I’d love to see some fiction in the list! ... View more

On rare occasion, I have reported startling findings that challenge current wisdom: Brain training games do NOT boost intelligence. Traumatic experiences are NOT often repressed. Seasonal affective disorder (wintertime blues) is NOT widespread.   The just-arrived lectures from the 2016 Bial Symposium on Placebo Effects, Healing and Meditation, offers another shocker: In an update on his meta-analyses, Irving Kirsch concludes that antidepressant drug effects are close to nil.   Here’s Kirsch’s gist: Many, many studies, including unpublished drug trials made available by the FDA, consistently show that Antidepressants work. They produce clinically significant benefits (using a standard depression scale). Placebos work, too. In two large meta-analyses, placebos produced 82 percent of the antidepressant effect. Moreover, “the difference between drug and placebo is . . . so small that clinicians cannot detect it.” Side effects can “unblind” a drug. The statistically (but not clinically) detectable drug effect may be attributable to antidepressants’ detectable side effects. The FDA only counts “successful trials.” Kirsch reports that despite meager evidence of antidepressant efficacy, the drugs gain approval because of a stunning FDA policy—which ignores trials that find no drug effect and reports only successful trials. “All antidepressant drugs seem to be equally effective.” As one would expect from a placebo effect, the benefits of various antidepressant drugs are “exactly the same regardless of type of drug.” Various serotonin-increasing drugs relieve depression, but so does a drug that decreases serotonin! “What do you call pills, the effects of which are independent of their chemical composition?,” asks Kirsch. “I call them ‘placebos.’”   Given that antidepressants work, even if they are hardly more than active placebos, what’s a clinician to recommend? Kirsch notes three considerations: Antidepressants have side effects, which can include sexual dysfunction, weight gain, insomnia, and diarrhea. Antidepressant use increases the risk of relapse after recovery. Cognitive behavioral therapy, acupuncture, and physical exercise also effectively treat depression. Ergo, “When different treatments are equally effective, choice should be based on risk and harm, and of all of these treatments, antidepressant drugs are the riskiest and most harmful. If they are to be used at all, it should be as a last resort.” But surely this is not the last word. Stay tuned for more findings and debate. ... View more

I am blessed to be collaborating with two incredibly high-achieving people. My introductory text co-author, Nathan DeWall, tells the story (here) of how he harnessed his own latent power of self-control. As research has shown and Nathan has experienced, self-control is like a muscle that can be temporarily depleted with use, but that gains strength with exercise—and with spillover benefits into other aspects of one’s life. Men’s Fitness has also just told the story of how Nathan became one of the world’s elite ultra marathoners. Jean Twenge, my co-author for new Social Psychology editions, has also made national news for her books, Generation Me and The Narcissism Epidemic. And she’s about to do so again with the late-August release of iGen: Why Today’s Super-Connected Kids Are Growing Up Less Rebellious, More Tolerant, Less Happy--and Completely Unprepared for Adulthood--and What That Means for the Rest of Us. The book, which no doubt will spark debate, will be featured in the September Atlantic. ... View more

After covering the therapy chapter in Intro Psych, students should have some tools to help them find a psychologist for themselves, family members, or friends when the time arises. The American Psychological Association (APA) has a “How to Choose a Psychologist” webpage. Ask students to read that page and then, working in pairs, small groups, or as a written assignment, answer the following questions. Under what circumstances does the APA suggest you should consider therapy? APA provides several suggestions for finding a psychologist. Which avenue would you try first and which would you try last? Why? Identify a potential issue that someone may have, such as high levels of anxiety. For each of the “Questions to ask,” what are some sample responses you would like to hear from a psychologist you are considering working with? [For the “What kinds of treatments” question, use what you learned from the therapy chapter to provide a sample response.] Next, ask students to read this New York Times Article, “How to find the right therapist.” Ask students to match the steps the author took to find a therapist with the steps the APA recommends. Using the APA recommendations, what else should the author have done? If doing this as part of a discussion, ask volunteers to report out. ... View more

Do you remember life before the Internet? Do you remember when you first got dial up? And then when cable internet first came along? And each time we were so excited. And then the excitement faded. Whatever change we experienced soon became the new normal. This is called adaptation-level phenomenon.  In 2015, Louis C. K., on Conan, gave us several good examples of adaptation-level phenomenon. He said, “Everything is amazing right now, and nobody‘s happy.” He blames it on the current generation. I blame it on being human. After playing this 4-minute clip for your students, ask your students to work in pairs or small groups to generate other examples that illustrate adaptation-level phenomenon.

Imagine that you and a colleague (or spouse) have been at odds. You have argued and fought, each trying to persuade the other. Alas, there has been no meeting of the minds. What might you do next to create an opportunity for conflict resolution? To “put behind” where you have been stuck, to “move on” from your standstill, to “get beyond” your impasse, one simple, practical strategy is literally to take steps forward—to go for a walk. In a new American Psychologist article, Christine Webb, Maya Rossignac-Milon, and E. Tory Higgins argue “that walking together can facilitate both the intra- and interpersonal pathways to conflict resolution.” At the individual level, they report, walking supports creativity. It boosts mood. It embodies notions of forward progress. At the interpersonal level, walking does more. Walkers’ synchronous movements, as they jointly attend to their environment and coordinate their steps, increases mutual rapport and empathy. It softens the boundary between self and other. And it engenders cooperation beyond the shared walking cadence. If, indeed, synchronous walking increases rapport and prosociality, might there be a similar effect of synchronized singing? Does group singing help unify a diverse audience? The question crossed my mind as folk singer Peter Yarrow (of “Peter, Paul and Mary”) rose near the beginning of a recent small group retreat of diverse people and invited us to join him in singing “Music Speaks Louder Than Words.” Yarrow, now age 79, has spent his career—from the civil rights and anti-war movements of the ´60s to today—in engaging audiences in synchronized singing of prosocial poetry. Photo courtesy Byron Buck What do you think? Does music speak louder than words alone? Do synchronized walking and group singing have overlapping psychological effects? Can both lift us beyond where words, in isolation, can take us? ... View more

Social psychologist Robert Cialdini has identified six principles of persuasion: scarcity, authority, consistency, reciprocity, consensus, and liking. In this post, we’ll give you examples of Cialdini’s principles of persuasion, as well as a quick classroom exercise to help you prepare for your lecture. Examples of Cialdini’s Persuasion Principles Here are some examples for your next social psychology lecture. Scarcity In 2015, Leslie, an employee at Food52, gave us a beautiful example of scarcity at work. “My mom brainwashed me as a kid. She put all of the candy out in the open and told me I could eat it whenever I wanted, but she'd hide the vegetables and tell me I could only eat them as a special treat at dinner. It worked. When I was six, I asked if I could have a bowl of brussels sprouts for my birthday instead of a cake” (Petertil, 2015). This is a good example of Cialdini’s scarcity principle, as the child’s perception of the vegetables as scarce influenced them to desire them more than they would have otherwise. This shows the power that scarcity can have in action. Authority Authority isn’t that hard to pull off if you’re a grandmother trolling your grandchildren. Reddit user pillowcurtain wrote in 2014 “My grandma told us that smelling each others [sic] farts would make us stronger. Worst Christmas ever for us, funniest Christmas for her.” Consistency Consistency is the principle that makes the foot-in-the-door technique work. A month ago I wrote a blog post explaining how airlines use foot-in-the-door to get us to pay more money to fly. Reciprocity Speaking of flying, reciprocity works with flight attendants, because, well, they’re human. Treats for flight attendants often result in reciprocated kindnesses (Strutner, 2016). I truly appreciate the work that flight attendants do, and I know that some of my fellow passengers can be challenging. I often bring baked goods to show a little love. But I don’t mind the reciprocity. On one flight, we were in the very last row. We brought Starbucks chocolate chunk muffins for the flight attendants. Not only did we get served food and adult beverages first (instead of last), we got them for free. And the flight attendants were very happy! Goodness all around. Consensus A couple of days ago I bought a new computer monitor for my home office. Do you have any idea how many different models of monitors are out there? Me neither, but the number has to be in the hundreds if not thousands. How in the world can I possibly get the best one for my price range? I started by reading reviews on sites like PCMagazine and CNET to narrow the field. And then I relied on consensus. The monitor I chose had 71% of the 232 customer reviews giving it 5 stars; another 15% gave it 4 stars. With 86% of the reviewers being pretty pleased with this particular monitor, well, that’s good enough for me. I’m looking at it now as I type. Likeable The more likable you are, the more likely you are to get what you want. Or even avoid something you don’t want. Malpractice attorney Alice Burkin said, “People just don't sue doctors they like. In all the years I've been in this business, I've never had a potential client walk in and say, ‘I really like this doctor, and I feel terrible about doing it, but I want to sue him.’ We've had people come in saying they want to sue some specialist, and we'll say ‘We don't think that doctor was negligent. We think it's your primary care doctor who was at fault:' And the client will say ‘I don't care what she did. I love her, and I'm not suing her’" (Rice, 2000). And I’m willing to bet it’s not just true for physicians. I recently heard from a department chair who had a student come by to vent about a policy her professor had that the student didn’t like. The chair asked the student if he would like to file a formal complaint against the professor. The student replied, “No! I like him!” Principles of Persuasion Classroom Exercise There you have it, six roads to persuasion. After covering these in class, ask students to work in pairs or small groups to generate their own examples. You can either assign a particular principle or two to each group or you can ask each group to generate at least one example for each principle. Afterward, ask volunteers to share their examples.  References Petertil, H. (2015, May 1). Remembering mom's best weird foods.
