The Smile: A Super-Powered Facial Expression
John M Grohol PsyD http://www.psychcentral.com
What’s In a Smile? For decades, psychology and its researchers have focused on the negative side of humanity — the things that bring dysfunction into our lives. Depression, sadness, anxiety, you name it. More recently, psychologists have also begun to better understand the value of positive emotions too. This understanding has resulted in a new field of research called “positive psychology” or “happiness research.”
So how do we recognize a positive emotion? Or put more simply, “What’s in a smile?”
A new paper just published by Disa Sauter (2010) helps us answer this question.
Happiness is In Your Smile
Psychological research into happiness has, for the most part, focused on facial expressions. It’s no wonder: most of our communication — both verbal and nonverbal — comes from our face. People across cultures understand the value of a smile and other facial expressions that point toward the emotion we call “being happy” or happiness. And we know that smiling itself can help increase positive, pro-social behaviors.
But how much research has examined more specific positive emotions in facial expressions? Surprisingly, only one study has been conducted that examined how the face displays specific positive emotions. The researchers in that study found:
[…] that displays of amusement and pride were signaled by smiles, but that amused smiles tended to be open-mouthed, whereas smiles of pride had compressed lips. In contrast, awe was typically expressed with raised eyebrows and a slightly open mouth, but not with smiles.
This study highlights that there is likely more than one kind of smile and that different smile configurations may communicate different affective states.
Smiles are more complicated that the simple communication of happiness. They can communicate a wide range of positive emotions, depending upon their specific makeup.
What about expressions of pride? Pride is considered a “secondary emotion” behind more basic emotions such as happiness and fear. Surprisingly, expressions of pride across cultures shares some specific characteristics:
Using photographs of participants from over 30 nations, Tracy and Matsumoto showed that individuals who won a fight produced a number of behaviors typically associated with pride expressions, including raising their arms, tilting their head back, smiling, and expanding their chest. This configuration of cues is recognized by observers as communicating pride.
Happy Noises & Touching
Just as with pride, there are apparently a number of universally recognized human sounds that express positive emotion. Research has shown that specific emotions recognized from sounds alone include amusement, triumph, sensual pleasure (the one we’re all most familiar with!) and relief.
You’d think that touch would be a sense that has been well-studied, given how important touch is to our emotional needs. But there has been very little research conducted examining the effects of human touch. What little research that has been done has found that certain positive emotions can sometimes be detected through touch:
They found that participants from two cultures (USA and Spain) could decode affective states from tactile stimulation on the arm. Emotions that were well recognized included several positive states, such as love, gratitude, and sympathy. Hertenstein et al. also showed that love was typically signaled with stroking, gratitude was communicated with a handshake, and sympathy was expressed with a patting movement.
Of course, some positive emotions are not well communicated through touch, including the general sense of “happiness.” Notice that only specific positive emotions — and only certain ones — are well-communicated through touch. Pride is an example of a positive emotion that has no equivalent touch sense.
Conclusions
What’s in a smile? A lot of information, telling the receiver of the smile whether you meant you were happy, amused, or proud. Research into human expression of positive emotions is ongoing and will explore more of these areas in years to come.
What we have found so far is that not every specific positive emotion — for instance, pride — is expressed through every type of sense.
As the researcher notes, “It will be interesting to consider whether ease of communication via different types of signals may relate to different “families” of emotions, such as self-conscious emotions including pride, and prosocial emotions like love.” If happiness can only be communicated through facial expressions, and not through touch, that’s good information to know when we think we’re communicating our happiness to a loved one through a specific gesture.
Happiness is a core component of life and living, and is associated with helping protect us against heart disease and enhancing our overall health. We also know that gratitude tends to lead to more happiness. The better we understand how happiness is expressed to others, perhaps the more clearly we’ll be able to communicate such emotions in the future.

An HBO biopic about Temple Grandin starring Claire Danes, and a new Jodi Picoult novel bring the issues and experiences of people with ASD to the general public this month. Reviews below:
Temple Grandin
By ALESSANDRA STANLEY http://www.nytimes.com Published: February 4, 2010
In her autobiography, “Thinking in Pictures: My Life With Autism,” Temple Grandin explains that she values “positive, measurable results more than emotion.” The HBO movie “Temple Grandin” honors its heroine’s priorities, stressing deeds over tearful setbacks and joyous breakthroughs.
That restraint, unusual in a portrait of a person who heroically overcomes a handicap, is oddly captivating and makes the story all the more touching. “Temple Grandin,” which has its debut on Saturday and stars Claire Danes in the title role, is a made-for-television biopic that avoids the mawkish clichés of the genre without draining the narrative of color and feeling.
Ms. Grandin was born in 1947 in Boston, and her autism was diagnosed when she was a child. At that time most psychiatrists considered it a mental disorder caused by cold, withholding “refrigerator mothers.” Helped by a mother who was anything but, Ms. Grandin was nurtured at home and by a few farsighted teachers who helped her unlock her talents. Most comfortable around animals, she grew up to become a sought after animal behaviorist and livestock consultant, world famous for designing humane slaughterhouses.
In some ways her story is harder to tell than other, similar tales of valor, be they “The Miracle Worker,” “My Left Foot” or “The Diving Bell and the Butterfly,” in which success is so intimately linked to disability. Helen Keller, Christy Brown and Jean-Dominique Bauby, the subjects of those movies, became famous because of their extraordinary personal histories; in all three cases their most lasting work is autobiographical.
Ms. Grandin credits autism for her achievements, arguing that she would never have been so attuned to animal sensibilities or the fine points of agricultural engineering without the distinctive vision and hypersensitivity that comes with autism.
But to the outside world her eminence and inner workings are incongruent. Ranchers don’t commission her stockyard designs because they are moved by her life story; parents and teachers of autistic children don’t care about her theories on curved cattle chutes, but view her accomplishments as a yardstick for their own hopes.
“Temple Grandin” fuses the two with a wonderstruck look at feedlots and loading ramps and a practical, pragmatic view of autism.
Viewers are thrown into the mindset of the teenage Temple with little introduction or fanfare, experiencing the world as she does: in blisteringly vivid images that pop into her head faster than a Google search and that she describes in her book as “full-color movies, complete with sound, which run like a VCR tape in my head.” In that sense, at least, her condition is ideally suited to moviemaking.
In an early scene in which Temple goes to visit her aunt on a ranch in Arizona, she gets off the airplane as startled and fearful as a feral animal. Sounds and sights are heightened — the screeching whirr of the propeller, shouted greetings, the flaming desert heat — to capture how overwhelming and unbearable they are to an autistic girl who flinches at the squeak of a felt-tip marker and cannot bear to be touched.
Ms. Danes is completely at ease in her subject’s lumbering gait and unmodulated voice. She makes Temple’s anxiety as immediate and contagious as her rarer bursts of merriment, laughing too loudly and over and over, as she re-enacts a scene from a favorite television show, “The Man From U.N.C.L.E.” And as the character ages and learns more social graces, Ms. Danes seamlessly captures Temple’s progress.
Julia Ormond looms surprisingly large in the small role of Eustacia, Temple’s mother, a fighter who insists that people treat her daughter as “different, but not less.” Ms. Grandin’s autobiography didn’t go into the family background — proper Bostonians with old money. Eustacia Cutler gives an account of it in her own, highly emotive autobiography, “A Thorn in My Pocket,” which has all the makings of a more lurid Lifetime movie and is perhaps wisely left out of the HBO film. But Ms. Ormond conveys the back story elliptically, adding a slight upper class inflection to her voice and showing Yankee stubbornness just beneath her sorrowed beauty. When a psychiatrist patronizingly tells Eustacia that her child has infantile schizophrenia brought on by maternal coldness, she snaps, “I’m supposed to have done this, well then, I can undo it.”
She sends Temple, who loves horseback riding, to Arizona for a summer, which introduces her to her life’s work, as well as a device to relieve her panic and anxiety: seeing how cows appear to calm down in squeeze chutes — metal stalls that press against the sides of animals to still them for inoculation — Temple tries it on herself, and finds comfort in the pressure. She designs a squeeze chute for herself, and that plywood contraption is just one of the many eccentricities that set her apart.
Temple finds a mentor, her high school science teacher, Dr. Carlock (David Strathairn), one of the first to train Temple to expand her intellect rather than merely control her impulses.
Students and other teachers were less kind. So were many of the ranchers and meat growers who stood in Temple’s way — and threw bull testicles at her car — when she began her studies in animal husbandry.
Hers is a tale that could be easily be played up for drama, intrigue and weepy reconciliations, but this narrative is loyal to Ms. Grandin’s credo: emotions are secondary to tangible results. And the result is a movie that is funny, instructive and also intangibly charming.
HBO, Saturday night at 8, Eastern and Pacific times; 7, Central time.
Directed by Mick Jackson; written by Christopher Monger and William Merritt Johnson; based on the books “Emergence” by Temple Grandin and Margaret Scariano, and “Thinking in Pictures” by Ms. Grandin; Emily Gerson Saines, Gil Bellows, Anthony Edwards, Dante Di Loreto, Paul Lister and Alison Owen, executive producers; Scott Ferguson, producer.

House Rules

Love the One You’re With: The Pitfalls of Seeking a “Soul Mate”
Has the quest for that one perfect partner, the never-ending search for the ideal done us more harm than good? There is growing evidence that an idealistic search for love can hinder the enjoyment and fulfilment of what you already have. The following is excerpted from Polly Schulman’s article at Psychology Today (http://psychologytoday.com ).
The divorce rate has stayed constant at nearly 50 percent for the last two decades. The ease with which we enter and dissolve unions makes marriage seem like a prime-time spectator sport, whether it’s Britney Spears in Vegas or bimbos chasing after the Bachelor.
Long live the new marriage! We once prized the institution for the practical pairing of a cash-producing father and a home-building mother. Now we want it all—a partner who reflects our taste and status, who sees us for who we are, who loves us for all the “right” reasons, who helps us become the person we want to be. We’ve done away with a rigid social order, adopting instead an even more onerous obligation: the mandate to find a perfect match. Anything short of this ideal prompts us to ask: Is this all there is? Am I as happy as I should be? Could there be somebody out there who’s better for me? As often as not, we answer yes to that last question and fall victim to our own great expectations.
That somebody is, of course, our soul mate, the man or woman who will counter our weaknesses, amplify our strengths and provide the unflagging support and respect that is the essence of a contemporary relationship. The reality is that few marriages or partnerships consistently live up to this ideal. The result is a commitment limbo, in which we care deeply for our partner but keep one stealthy foot out the door of our hearts. In so doing, we subject the relationship to constant review: Would I be happier, smarter, a better person with someone else? It’s a painful modern quandary. “Nothing has produced more unhappiness than the concept of the soul mate,” says Atlanta psychiatrist Frank Pittman [….
… ] Many of us either dodge the decision to commit or commit without fully relinquishing the right to keep looking—opting for an arrangement psychotherapist Terrence Real terms “stable ambiguity.” “You park on the border of the relationship, so you’re in it but not of it,” he says. There are a million ways to do that: You can be in a relationship but not be sure it’s really the right one, have an eye open for a better deal or something on the side, choose someone impossible or far away.
Yet commitment and marriage offer real physical and financial rewards. Touting the benefits of marriage may sound like conservative policy rhetoric, but nonpartisan sociological research backs it up: Committed partners have it all over singles, at least on average. Married people are more financially stable, according to Linda Waite, a sociologist at the University of Chicago and a coauthor of The Case for Marriage: Why Married People Are Happier, Healthier, and Better Off Financially Both married men and married women have more assets on average than singles; for women, the differential is huge.
The benefits go beyond the piggy bank. Married people, particularly men, tend to live longer than people who aren’t married. Couples also live better: When people expect to stay together, says Waite, they pool their resources, increasing their individual standard of living. They also pool their expertise—in cooking, say, or financial management. In general, women improve men’s health by putting a stop to stupid bachelor tricks and bugging their husbands to exercise and eat their vegetables. Plus, people who aren’t comparing their partners to someone else in bed have less trouble performing and are more emotionally satisfied with sex. The relationship doesn’t have to be wonderful for life to get better, says Waite: The statistics hold true for mediocre marriages as well as for passionate ones.
The pragmatic benefits of partnership used to be foremost in our minds. The idea of marriage as a vehicle for self-fulfillment and happiness is relatively new, says Paul Amato, professor of sociology, demography and family studies at Penn State University. Surveys of high school and college students 50 or 60 years ago found that most wanted to get married in order to have children or own a home. Now, most report that they plan to get married for love. This increased emphasis on emotional fulfillment within marriage leaves couples ill-prepared for the realities they will probably face.
Because the early phase of a relationship is marked by excitement and idealization, “many romantic, passionate couples expect to have that excitement forever,” says Barry McCarthy, a clinical psychologist and coauthor—with his wife, Emily McCarthy—of Getting It Right the First Time: Creating a Healthy Marriage. Longing for the charged energy of the early days, people look elsewhere or split up.
Flagging passion is often interpreted as the death knell of a relationship. You begin to wonder whether you’re really right for each other after all. You’re comfortable together, but you don’t really connect the way you used to. Wouldn’t it be more honest—and braver—to just admit that it’s not working and call it off? “People are made to feel that remaining in a marriage that doesn’t make you blissfully happy is an act of existential cowardice,” says Joshua Coleman, a San Francisco psychologist.
Coleman says that the constant cultural pressure to have it all—a great sex life, a wonderful family—has made people ashamed of their less-than-perfect relationships and question whether such unions are worth hanging on to. Feelings of dissatisfaction or disappointment are natural, but they can seem intolerable when standards are sky-high. “It’s a recent historical event that people expect to get so much from individual partners,” says Coleman, author of The Marriage Makeover: Finding Happiness in Imperfect Harmony in which he advises couples in lackluster marriages to stick it out—especially if they have kids. “There’s an enormous amount of pressure on marriages to live up to an unrealistic ideal.” […
…] In fact, argue psychologists and marital advocates, there’s no such thing as true compatibility. “Marriage is a disagreement machine,” says Diane Sollee, founder of the Coalition for Marriage, Family and Couples Education. “All couples disagree about all the same things. We have a highly romanticized notion that if we were with the right person, we wouldn’t fight.” Discord springs eternal over money, kids, sex and leisure time, but psychologist John Gottman has shown that long-term, happily married couples disagree about these things just as much as couples who divorce.
“There is a mythology of ‘the wrong person,'” agrees Pittman. “All marriages are incompatible. All marriages are between people from different families, people who have a different view of things. The magic is to develop binocular vision, to see life through your partner’s eyes as well as through your own.”
The realization that we’re not going to get everything we want from a partner is not just sobering, it’s downright miserable. But it is also a necessary step in building a mature relationship, according to Real, who has written about the subject in How Can I Get Through to You? Closing the Intimacy Gap Between Men and Women
. “The paradox of intimacy is that our ability to stay close rests on our ability to tolerate solitude inside a relationship,” he says. “A central aspect of grown-up love is grief. All of us long for—and think we deserve—perfection.” We can hardly be blamed for striving for bliss and self-fulfillment in our romantic lives—our inalienable right to the pursuit of happiness is guaranteed in the first blueprint of [..modern] society.
This same respect for our own needs spurred the divorce-law reforms of the 1960s and 1970s. During that era, “The culture shifted to emphasize individual satisfaction, and marriage was part of that,” explains Paul Amato, who has followed more than 2,000 families for 20 years in a long-term study of marriage and divorce. Amato says that this shift did some good by freeing people from abusive and intolerable marriages. But it had an unintended side effect: encouraging people to abandon relationships that may be worth salvaging. In a society hell-bent on individual achievement and autonomy, working on a difficult relationship may get short shrift, says psychiatrist Peter Kramer, author of Should You Leave?
“So much of what we learn has to do with the self, the ego, rather than giving over the self to things like a relationship,” Kramer says. In our competitive world, we’re rewarded for our individual achievements rather than for how we help others. We value independence over cooperation, and sacrifices for values like loyalty and continuity seem foolish. “I think we get the divorce rate that we deserve as a culture.”
The steadfast focus on our own potential may turn a partner into an accessory in the quest for self-actualization, says Maggie Robbins, a therapist in New York City. “We think that this person should reflect the beauty and perfection that is the inner me—or, more often, that this person should compensate for the yuckiness and mess that is the inner me,” says Robbins. “This is what makes you tell your wife, ‘Lose some weight—you’re making me look bad,’ not ‘Lose some weight, you’re at risk for diabetes.'” […
…] The urge to find a soul mate is not fueled just by notions of romantic manifest destiny. Trends in the workforce and in the media create a sense of limitless romantic possibility. According to Scott South, a demographer at SUNY-Albany, proximity to potential partners has a powerful effect on relationships. South and his colleagues found higher divorce rates among people living in communities or working in professions where they encounter lots of potential partners—people who match them in age, race and education level. “These results hold true not just for unhappy marriages but also for happy ones,” says South.
The temptations aren’t always living, breathing people. According to research by psychologists Sara Gutierres and Douglas Kenrick, both of Arizona State University, we find reasonably attractive people less appealing when we’ve just seen a hunk or a hottie—and we’re bombarded daily by images of gorgeous models and actors. When we watch Lord of the Rings, Viggo Mortensen’s kingly mien and Liv Tyler’s elfin charm can make our husbands and wives look all too schlumpy.
Kramer sees a similar pull in the narratives that surround us. “The number of stories that tell us about other lives we could lead—in magazine articles, television shows, books—has increased enormously. We have an enormous reservoir of possibilities,” says Kramer.
And these possibilities can drive us to despair. Too many choices have been shown to stymie consumers, and an array of alternative mates is no exception. In an era when marriages were difficult to dissolve, couples rated their marriages as more satisfying than do today’s couples, for whom divorce is a clear option, according to the National Opinion Research Center at the University of Chicago.
While we expect marriage to be “happily ever after,” the truth is that for most people, neither marriage nor divorce seem to have a decisive impact on happiness. Although Waite’s research shows that married people are happier than their single counterparts, other studies have found that after a couple years of marriage, people are just about as happy (or unhappy) as they were before settling down. And assuming that marriage will automatically provide contentment is itself a surefire recipe for misery.
“Marriage is not supposed to make you happy. It is supposed to make you married,” says Pittman. “When you are all the way in your marriage, you are free to do useful things, become a better person.” A committed relationship allows you to drop pretenses and seductions, expose your weaknesses, be yourself—and know that you will be loved, warts and all. “A real relationship is the collision of my humanity and yours, in all its joy and limitations,” says Real. “How partners handle that collision is what determines the quality of their relationship.”
Such a down-to-earth view of marriage is hardly romantic, but that doesn’t mean it’s not profound: An authentic relationship with another person, says Pittman, is “one of the first steps toward connecting with the human condition—which is necessary if you’re going to become fulfilled as a human being.” If we accept these humble terms, the quest for a soul mate might just be a noble pursuit after all.
source: PsychologyToday.comSex: Is that all that men want?…NOPE!
A study from the Kinsey Institute strongly challenges the myth that men value sex more highly than other things. The findings relating to what men value and how they rate their sense of masculinity are robust across age, nationality and erectile function. Diana KirschnerPhD. has summarised the findings on the Psychology Today site (http://psychologytoday.com ) as follows:
View The Original Research Paper HERE (Free PDF -internal link)
“(The) data … came out of an eight country random survey of 27,839 men ages 20-752. Using a questionnaire called the Men’s Attitudes to Life Events and Sexuality(MALES), the authors found men’s attitudes towards two key areas, masculinity and quality of life, differed markedly from the cultural stereotypes of guys as shallow creatures who are driven primarily by lust.
In the masculinity section of the study and across all countries, being seen as a “man of honor” was the single highest ideal for men, far more important than “being physically attractive,” “having success with women,” or “having an active sex life.” Together with “being in control of your own life” these two attributes accounted for about 60% of the responses. These findings held across all nationalities and across all age groups.
In the MALES section called Quality of Life, men were asked to rate the following seven
• Being in good health
• Satisfying sex life
• Harmonious family life
• Good relationship with partner/wife
• Enjoying life to the fullest
• Satisfying
• Having a nice home
Again, the findings were quite surprising. The top three answers were: “being in good health”; “a harmonious family life”; and “good relationship with partner/wife.” “A satisfying sex life” was last, tied with “a nice home.” While there was definitely variability in the top answersdepending on country, “a satisfying sex life” always came last. Even more astonishing were the findings in regard to age and marital/partner status. Younger men, age 20-39 still rated the same three goals as most important. When comparing single vs. married men, the only difference was that singles rated “enjoying live to the fullest” in second placealong with “a harmonious family life”-while “a good relationship with their partner” was ranked fourth. Again “a satisfying sex life” was rated last.
Amazingly enough men who had erectile dysfunction (ED) as well as those who did not, still rated “a satisfying sex life” the same way-dead last. Understandably, men with ED reported having a less satisfying sexual life than those without ED.”

Here’s the abstract:
Introduction. The Men’s Attitudes to Life Events and Sexuality (MALES) study assessed the prevalence of erectile dysfunction, and examined men’s attitudes and behavior in relation to this dysfunction.
Aim. To report on the attitudes of men, with and without self-reported erectile dysfunction, concerning masculine identity and quality of life.
Methods. The MALES Phase I study included 27,839 randomly selected men (aged 20–75 years) from eight countries (United States, United Kingdom, Germany, France, Italy, Spain, Mexico, and Brazil) who responded to a standardized computer-assisted telephone interview.Main Outcome Measure. Perceptions of masculinity and quality of life in men with and without erectile dysfunction.
Results. Men’s perceptions of masculinity differed substantially from stereotypes in the literature. Men reported that being seen as honorable, self-reliant, and respected by friends were important determinants of self-perceived masculinity. In contrast, factors stereotypically associated with masculinity, such as being physically attractive,sexually active, and successful with women, were deemed to be less important to men’s sense of masculinity. These findings appeared consistently across all nationalities and all age groups studied. For quality of life, factors that men deemed of significant importance included good health, harmonious family life, and a good relationship with their wife/partner. Such factors had significantly greater importance to quality of life than concerns such as having a good job, having a nice home, living life to the full, or having a satisfying sex life. Of note, rankings of constructs of masculinity and quality of life did not meaningfully differ in men with or without erectile dysfunction, and men with erectile dysfunction who did or did not seek treatment for their sexual dysfunction.
Conclusions. The present findings highlight the significance of partnered relationships and interpersonal factors in the management of erectile dysfunction, and empirically challenge a number of widely held stereotypes concerning men, masculinity, sex, and quality of life.

Facebook: Is it Really your Face or Someone Else’s?
Do people display their actual or idealised personalities on social networking sites? This interesting article from PsyBlog reports that recent research addressed this issue with surprising results. I wonder if similar research on role playing and avatar based environments like World of Warcraft and Second Life would yield different findings…
There are now over 700 million people around the world with profiles on social networking sites like Facebook and MySpace. In the US 75% of those between 18 and 24 who have access to the internet use social networking sites. And over the past four years, across all adult age-groups, their use has quadrupled.
But do these profiles tell us anything about people’s real-life personalities? Online it is very easy to display an idealised version of the self to others so surely the temptation to exaggerate or even give a completely misleading impression is just too great?
Actual versus idealised personality
To find out psychologists recruited 236 US and German students who use social networking sites and had them complete personality measures (Back et al., 2010).
These measured first their actual personalities on what psychologists call the ‘Big 5‘ personality traits (extraversion, agreeableness, conscientiousness, neuroticism and openness to experience).
Secondly it measured their idealised personalities: who they would like to be. Then independent observers were shown their real social networking profiles and asked to rate participants’ personalities.
The surprising truth
After comparing the actual personalities with the idealised and observed, the researchers found that, on average, people were much more likely to display their real personality on the social networking sites rather than their idealised selves.
Overall people were remarkably honest in representing themselves. People were honest—we don’t read those words often enough.
In line with other findings, this study found that, when looking at a stranger’s profile for the first time, some aspects of personality are more difficult to discern. Neuroticism in others is particularly difficult to gauge, whereas people find extraversion and openness to experience relatively easily to assess, even in strangers.
Lying online?
This study is another blow for that old stereotype that the web is some kind of scary hinterland, an untrustworthy place where anything goes and nothing is what it appears, peopled by adolescent boys pretending to be anything but adolescent boys.
Contrary to the received wisdom, as well as academic theorising that the internet encourages people to project an idealised self, this research suggests that people are remarkably honest in displaying their true personalities online.
Whatever the cause, this fact may help to explain the phenomenal popularity of social networking sites: the truth draws people in.

Viva La Siesta!: A Nap Significantly Boosts the Brain’s Learning Capacity
BERKELEY — If you see a student dozing in the library or a co-worker catching 40 winks in her cubicle, don’t roll your eyes. New research from the University of California, Berkeley, shows that an hour’s nap can dramatically boost and restore your brain power. Indeed, the findings suggest that a biphasic sleep schedule not only refreshes the mind, but can make you smarter.
Conversely, the more hours we spend awake, the more sluggish our minds become, according to the findings. The results support previous data from the same research team that pulling an all-nighter — a common practice at college during midterms and finals — decreases the ability to cram in new facts by nearly 40 percent, due to a shutdown of brain regions during sleep deprivation.
“Sleep not only rights the wrong of prolonged wakefulness but, at a neurocognitive level, it moves you beyond where you were before you took a nap,” said Matthew Walker, an assistant professor of psychology at UC Berkeley and the lead investigator of these studies.
In the recent UC Berkeley sleep study, 39 healthy young adults were divided into two groups — nap and no-nap. At noon, all the participants were subjected to a rigorous learning task intended to tax the hippocampus, a region of the brain that helps store fact-based memories. Both groups performed at comparable levels.
At 2 p.m., the nap group took a 90-minute siesta while the no-nap group stayed awake. Later that day, at 6 p.m., participants performed a new round of learning exercises. Those who remained awake throughout the day became worse at learning. In contrast, those who napped did markedly better and actually improved in their capacity to learn.
Matthew Walker, assistant psychology professor, has found that a nap clears the brain to absorb new information.
These findings reinforce the researchers’ hypothesis that sleep is needed to clear the brain’s shor
t-term memory storage and make room for new information, said Walker, who presented his preliminary findings on Sunday, Feb. 21, at the annual meeting of the American Association of the Advancement of Science (AAAS) in San Diego, Calif.
Since 2007, Walker and other sleep researchers have established that fact-based memories are temporarily stored in the hippocampus before being sent to the brain’s prefrontal cortex, which may have more storage space.
“It’s as though the e-mail inbox in your hippocampus is full and, until you sleep and clear out those fact e-mails, you’re not going to receive any more mail. It’s just going to bounce until you sleep and move it into another folder,” Walker said.
In the late
st study, Walker and his team have broken new ground in discovering that this memory-refreshing process occurs when nappers are engaged in a specific stage of sleep. Electroencephalogram tests, which measure electrical activity in the brain, indicated that this refreshing of memory capacity is related to Stage 2 non-REM sleep, which takes place between deep sleep (non-REM) and the dream state known as Rapid Eye Movement (REM). Previously, the purpose of this stage was unclear, but the new results offer evidence as to why humans spend at least half their sleeping hours in Stage 2, non-REM, Walker said.
“I can’t imagine Mother Nature would have us spend 50 percent of the night going from one sleep stage to another for no reason,” Walker said. “Sleep is sophisticated. It acts locally to give us what we need.”
Walker and his team will go on to investigate whether the reduction of sleep experienced by people as they get older is related to the documented decrease in our ability to learn as we age. Finding that link may be helpful in understanding such neurodegenerative conditions as Alzheimer’s disease, Walker said.
In addition to Walker, co-investigators of these new findings are Bryce A. Mander and psychology undergraduate Sangeetha Santhanam.

More than Words: The Importance of Physical Touch
Psychologists have long studied the grunts and winks of nonverbal communication, the vocal tones and facial expressions that carry emotion. A warm tone of voice, a hostile stare — both have the same meaning in Terre Haute or Timbuktu, and are among dozens of signals that form a universal human vocabulary.
But in recent years some researchers have begun to focus on a different, often more subtle kind of wordless communication: physical contact. Momentary touches, they say — whether an exuberant high five, a warm hand on the shoulder, or a creepy touch to the arm — can communicate an even wider range of emotion than gestures or expressions, and sometimes do so more quickly and accurately than words.
“It is the first language we learn,” said Dacher Keltner, a professor of psychology at the University of California, Berkeley, and the author of “Born to Be Good: The Science of a Meaningful Life” (Norton, 2009), and remains, he said, “our richest means of emotional expression” throughout life.
The evidence that such messages can lead to clear, almost immediate changes in how people think and behave is accumulating fast. Students who received a supportive touch on the back or arm from a teacher were nearly twice as likely to volunteer in class as those who did not, studies have found. A sympathetic touch from a doctor leaves people with the impression that the visit lasted twice as long, compared with estimates from people who were untouched. Research by Tiffany Field of the Touch Research Institute in Miami has found that a massage from a loved one can not only ease pain but also soothe depression and strengthen a relationship.
In a series of experiments led by Matthew Hertenstein, a psychologist at DePauw University in Indiana, volunteers tried to communicate a list of emotions by touching a blindfolded stranger. The participants were able to communicate eight distinct emotions, from gratitude to disgust to love, some with about 70 percent accuracy.
“We used to think that touch only served to intensify communicated emotions,” Dr. Hertenstein said. Now it turns out to be “a much more differentiated signaling system than we had imagined.”
To see whether a rich vocabulary of supportive touch is in fact related to performance, scientists at Berkeley recently analyzed interactions in one of the most physically expressive arenas on earth: professional basketball. Michael W. Kraus led a research team that coded every bump, hug and high five in a single game played by each team in the National Basketball Association early last season.
In a paper due out this year in the journal Emotion, Mr. Kraus and his co-authors, Cassy Huang and Dr. Keltner, report that with a few exceptions, good teams tended to be touchier than bad ones. The most touch-bonded teams were the Boston Celtics and the Los Angeles Lakers, currently two of the league’s top teams; at the bottom were the mediocre Sacramento Kings and Charlotte Bobcats.
The same was true, more or less, for players. The touchiest player was Kevin Garnett, the Celtics’ star big man, followed by star forwards Chris Bosh of the Toronto Raptors and Carlos Boozer of the Utah Jazz. “Within 600 milliseconds of shooting a free throw, Garnett has reached out and touched four guys,” Dr. Keltner said.
To correct for the possibility that the better teams touch more often simply because they are winning, the researchers rated performance based not on points or victories but on a sophisticated measure of how efficiently players and teams managed the ball — their ratio of assists to giveaways, for example. And even after the high expectations surrounding the more talented teams were taken into account, the correlation persisted. Players who made contact with teammates most consistently and longest tended to rate highest on measures of performance, and the teams with those players seemed to get the most out of their talent.
The study fell short of showing that touch caused the better performance, Dr. Kraus acknowledged. “We still have to test this in a controlled lab environment,” he said.
If a high five or an equivalent can in fact enhance performance, on the field or in the office, that may be because it reduces stress. A warm touch seems to set off the release of oxytocin, a hormone that helps create a sensation of trust, and to reduce levels of the stress hormone cortisol.
In the brain, prefrontal areas, which help regulate emotion, can relax, freeing them for another of their primary purposes: problem solving. In effect, the body interprets a supportive touch as “I’ll share the load.”
“We think that humans build relationships precisely for this reason, to distribute problem solving across brains,” said James A. Coan, a a psychologist at the University of Virginia. “We are wired to literally share the processing load, and this is the signal we’re getting when we receive support through touch.”
The same is certainly true of partnerships, and especially the romantic kind, psychologists say. In a recent experiment, researchers led by Christopher Oveis of Harvard conducted five-minute interviews with 69 couples, prompting each pair to discuss difficult periods in their relationship.
The investigators scored the frequency and length of touching that each couple, seated side by side, engaged in. In an interview, Dr. Oveis said that the results were preliminary.
“But it looks so far like the couples who touch more are reporting more satisfaction in the relationship,” he said. Again, it’s not clear which came first, the touching or the satisfaction. But in romantic relationships, one has been known to lead to the other. Or at least, so the anecdotal evidence suggests.
