Pack Up Your Troubles And (Apparently) Smile: Physical Enclosure Helps Psychological Closure
Read the original research paper HERE (Free PDF-internal link)
ScienceDaily (Mar. 25, 2010) — Finding it hard to get over a failed love interest? Just can’t get details of a bad financial move out of your head.
A new study from the Rotman School of Management suggests you might want to stick something related to your disappointment in a box or envelope if you want to feel better. In four separate experiments researchers found that the physical act of enclosing materials related to an unpleasant experience, such as a written recollection about it, improved people’s negative feelings towards the event and created psychological closure. Enclosing materials unrelated to the experience did not work as well.
“If you tell people, ‘You’ve got to move on,’ that doesn’t work,” said Dilip Soman, who holds the Corus Chair in Communication Strategy at the Rotman School and is also a professor of marketing, who co-wrote the paper with colleagues Xiuping Li from the National University of Singapore and Liyuan Wei from City University of Hong Kong. “What works is when people enclose materials that are relevant to the negative memories they have. It works because people aren’t trying to explicitly control their emotions.”
While the market implications might not be immediately obvious, Prof. Soman believes the findings point to new angles on such things as fast pick-up courier services and pre-paid mortgage deals that relieve people’s sense of debt burden. If people realize that the memory of past events or tasks can be distracting, perhaps there is a market for products and services that can enclose or take away memories of that task.
The paper is to be published in Psychological Science.

Game On: The Decline of Backyard Play
I found this post from Peter G. Stromberg @ Psychology Today. It really got me thinking about kids and the pressure that we may put on them as parents…What do you think?
A few weeks ago I flew to Denver with my younger daughter so that she could participate in a volleyball tournament; she has been travelling to tournaments for the last two years but this is the first time we had to fly. My daughter is 11 years old.
Shouldn’t my daughter be riding her bike around the neighborhood and jumping rope with her friends? Why is she, at age 11, playing on a team coached by a former Olympic-level athlete and competing against nationally-ranked teams based thousands of miles from our home? There is research to suggest that unstructured play and basic movement activities (running, jumping, balancing) are more beneficial for children of her age than specialized training in one particular sport. Why in the world should an 11 year old child be in year-round volleyball training? Well, let me explain.
I would guess that many readers who are older than 30 will share my own experience: at my daughter’s age and into my early teens, I spent every possible minute getting into pick-up games of basketball and football with my friends or just roaming around outside. This approach didn’t produce a skilled athlete, but it sure was fun (and cheap). Today, in most areas of the country, such activities are simply less available. One reason my daughter doesn’t head down to the park to play with her friends is that they aren’t there-they are at soccer practice, or piano lessons, or having pre-arranged play dates.
There has been a recent and enormous shift in the way children play in our society, away from unstructured outside play and towards organized competition under adult supervision. Why? One reason that will come quickly to mind is stranger danger. Many parents (including me, by the way) now believe it is unsafe for children-perhaps particularly girls-to be outside without adult supervision. Although neighborhoods vary, statistics that I have seen on this issue do not support the belief that in general accidents or attacks on children are more frequent now than, say, 30 years ago. It seems more likely that what has changed is extensive news coverage of issues such as attacks on children, which often fosters the belief that such events are frequent.
In short, actual danger from strangers is probably not the real reason for the decline in outside play. Well, how about this? Public funding for playgrounds, parks, and recreation centers has been declining since the 1980s. There aren’t as many places to go for public play anymore, and the ones that persist are likely not as well-maintained.
That’s relevant, but it still isn’t really at the heart of why my daughter plays highly competitive volleyball at such a young age. The fact is that if she doesn’t play now and decides to take up the sport at 14 or 15, the train will have left the station. Unless a child has extraordinary athletic gifts, she will be so far behind by that age that she will not be able to find a place on a team. It isn’t only that opportunities for unstructured public play have declined, it’s that opportunities for highly competitive play have expanded to such an extent that in some sports that is all that exists. There are simply no possibilities in my part of the country for recreational volleyball for children 10-18. And the situation is similar for many other sports as well: our focus on producing highly competitive teams with highly skilled participants leads to a lack of focus on producing opportunities for children who simply want to play a sport casually.
This, I think, gets us close to probably the most important reason that highly competitive sport for the few has begun to replace recreational sport for the many among children today. We as a society don’t care about recreational sport for the many. The logic of entertainment has come to control youth sports. Parents, kids, and the society as a whole are excited by the possibility of championships, cheering spectators, and (for the really elite) media coverage. And we aren’t really excited by our children playing disorganized touch football until they have to come in for dinner. What’s the point of that? Nobody is watching.
This isn’t anyone’s fault, it’s just the way our society works. I really wish my kids could play pick up games and intramurals the way their not-so-athletically-talented dad did. But the intramurals and pick up games are far fewer now. Strangely enough, childhood obesity rates have skyrocketed as they have faded. Or maybe that’s not strange at all.
This post reflects on issues I have been thinking about for years, but it is also heavily influenced by a recent book called Game On by ESPN writer Tom Farrey. To learn more about play in general, visit my website

Money & Happiness: Higher Income Only Increases Contentment If You’re ‘Keeping Up With The Jones’s’
Read the original research paper HERE (Free PDF internal link)
Source :ScienceDaily (Mar. 22, 2010)
A study by researchers at the University of Warwick and Cardiff University has found that money only makes people happier if it improves their social rank. The researchers found that simply being highly paid wasn’t enough — to be happy, people must perceive themselves as being more highly paid than their friends and work colleagues.
The researchers were seeking to explain why people in rich nations have not become any happier on average over the last 40 years even though economic growth has led to substantial increases in average incomes.
Lead researcher on the paper Chris Boyce from the University of Warwick’s Department of Psychology said: “Our study found that the ranked position of an individual’s income best predicted general life satisfaction, while the actual amount of income and the average income of others appear to have no significant effect. Earning a million pounds a year appears to be not enough to make you happy if you know your friends all earn 2 million a year.”
The study entitled “Money and Happiness: Rank of Income, Not Income, Affects Life Satisfaction” will be published in the journal Psychological Science. The researchers looked at data on earnings and life satisfaction from seven years of the British Household Panel Survey (BHPS), which is a representative longitudinal sample of British households.
First they examined how life satisfaction was related to how much money each person earned. They found however that satisfaction was much more strongly related to the ranked position of the person’s income (compared to people of the same gender, age, level of education, or from the same geographical area).
The results explain why making everybody in society richer will not necessarily increase overall happiness — because it is only having a higher income than other people that matters.
The three authors of the paper were Chris Boyce, Gordon Brown (both of the University of Warwick’s Department of Psychology), and Simon Moore of Cardiff University.

Improve Self Control and Impulsivity Through Abstract Thinking
Read Original Research Paper HERE (Free PDF internal link)
[A] New study shows that self-control can be automatically, unconsciously bolstered by abstract thinking.
Wouldn’t it be great if we could just spontaneously and automatically exercise self-control, without all that painful back-and-forth battle with ourselves?
Just automatically resist that cake and choose the apple; or suddenly find ourselves out jogging without resorting to self-blackmail […]
Unfortunately so often temptation wins. And experiments show that when we are run down from exercising self-discipline all day, we become even more likely to give in to temptation.
Apple or candy bar?
[Previous studies suggest ]that self-control can be increased by thinking abstractly about our goals. This suggests we should see our actions as just one part of a larger plan, rather than focusing on the details of what we’re doing. The power of abstract thinking may offer a way for us to increase our self-control without really trying.
But how does thinking abstractly about our goals increase our self-control? In a recent article published in Psychological Science, Fujita and Han (2009) wondered if our unconscious mind is somehow pitching in to help out. They used an implicit association test as a way of measuring people’s unconscious thoughts about eating either an apple or a tempting candy bar.
Before taking this test people were put into either an abstract or concrete mode of thinking. Participants were split into two groups with each asked to think about maintaining good personal relationships, but in different ways. One group thought about why we need to maintain good relationships (abstract, high-level) while the other focused on how we maintain good relationships (concrete, low-level).
As you can see, for the purposes of this experiment, the reason participants were thinking abstractly didn’t matter so much. That’s because when we think abstractly about one thing, we tend to carry on thinking in an abstract mode about anything else that’s put in front of us, including the choice between an apple and a candy bar.
Automatic, unconscious self-control
The results showed that, when participants were thinking concretely, they tended to unconsciously see candy bars in a positive light and apples in a negative light. But this was reversed when participants were thinking abstractly. Just as predicted, abstract thinking automatically made people unconsciously think of candy bars as the devil’s own food.
To back this up they asked participants in the two conditions whether they would like an apple or a candy bar, right now. They found that when participants were thinking in a concrete low-level way, they chose the apple over the candy bar only 50% of the time. But when they were thinking abstractly this percentage shot up to 76%. Not bad for such a simple manipulation.
So it seems you can bolster resistance to temptation by thinking abstractly about the goal you want to obtain because it causes your mind to automatically associate temptations with negativity. Hey presto, more self-control and thank you unconscious mind.
Why not try applying this to whatever you are finding difficult to achieve?

Pay It Forward: Research Proves That Acts Of Kindness From A Few Cascade On To Dozens
Read The Original Research Paper HERE (Free PDF)
ScienceDaily (Mar. 10, 2010) — For all those dismayed by scenes of looting in disaster-struck zones, whether Haiti or Chile or elsewhere, take heart: Good acts — acts of kindness, generosity and cooperation — spread just as easily as bad. And it takes only a handful of individuals to really make a difference.

This diagram illustrates how a single act of kindness can spread between individuals and across time. Cooperative behavior spreads three degrees of separation
In a study published in the March 8 early online edition of the Proceedings of the National Academy of Sciences, researchers from the University of California, San Diego and Harvard provide the first laboratory evidence that cooperative behavior is contagious and that it spreads from person to person to person. When people benefit from kindness they “pay it forward” by helping others who were not originally involved, and this creates a cascade of cooperation that influences dozens more in a social network.
The research was conducted by James Fowler, associate professor at UC San Diego in the Department of Political Science and Calit2’s Center for Wireless and Population Health Systems, and Nicholas Christakis of Harvard, who is professor of sociology in the Faculty of Arts and Sciences and professor of medicine and medical sociology at Harvard Medical School. Fowler and Christakis are coauthors of the recently published book Connected: The Surprising Power of Our Social Networks and How They Shape Our Lives.
In the current study, Fowler and Christakis show that when one person gives money to help others in a “public-goods game,” where people have the opportunity to cooperate with each other, the recipients are more likely to give their own money away to other people in future games. This creates a domino effect in which one person’s generosity spreads first to three people and then to the nine people that those three people interact with in the future, and then to still other individuals in subsequent waves of the experiment.
The effect persists, Fowler said: “You don’t go back to being your ‘old selfish self.”’ As a result, the money a person gives in the first round of the experiment is ultimately tripled by others who are subsequently (directly or indirectly) influenced to give more. “The network functions like a matching grant,” Christakis said.
“Though the multiplier in the real world may be higher or lower than what we’ve found in the lab,” Fowler said, “personally it’s very exciting to learn that kindness spreads to people I don’t know or have never met. We have direct experience of giving and seeing people’s immediate reactions, but we don’t typically see how our generosity cascades through the social network to affect the lives of dozens or maybe hundreds of other people.”
The study participants were strangers to each other and never played twice with the same person, a study design that eliminates direct reciprocity and reputation management as possible causes.
In previous work demonstrating the contagious spread of behaviors, emotions and ideas — including obesity, happiness, smoking cessation and loneliness — Fowler and Christakis examined social networks re-created from the records of the Framingham Heart Study. But like all observational studies, those findings could also have partially reflected the fact that people were choosing to interact with people like themselves or that people were exposed to the same environment. The experimental method used here eliminates such factors.
The study is the first work to document experimentally Fowler and Christakis’s earlier findings that social contagion travels in networks up to three degrees of separation, and the first to corroborate evidence from others’ observational studies on the spread of cooperation.
The contagious effect in the study was symmetric; uncooperative behavior also spread, but there was nothing to suggest that it spread any more or any less robustly than cooperative behavior, Fowler said.
From a scientific perspective, Fowler added, these findings suggest the fascinating possibility that the process of contagion may have contributed to the evolution of cooperation: Groups with altruists in them will be more altruistic as a whole and more likely to survive than selfish groups.
“Our work over the past few years, examining the function of human social networks and their genetic origins, has led us to conclude that there is a deep and fundamental connection between social networks and goodness,” said Christakis. “The flow of good and desirable properties like ideas, love and kindness is required for human social networks to endure, and, in turn, networks are required for such properties to spread. Humans form social networks because the benefits of a connected life outweigh the costs.”
The research was funded by the National Institute on Aging, the John Templeton Foundation, and a Pioneer Grant from the Robert Wood Johnson Foundation.

Happiness: Why It’s Harder to Find in Depression’s “Shrinking World”
http://www.PsychologicalScience.org via http://www.psychcentral.comA new research study investigated whether happy and unhappy people differ in the types of conversations they tend to engage in.
For a four-day period, psychological scientists from the University of Arizona and Washington University in St. Louis had volunteers equipped with an unobtrusive recording device called the Electronically Activated Recorder (EAR).
This device periodically records snippets of sounds as participants go about their lives. For this experiment, the EAR sampled 30 seconds of sounds every 12.5 minutes yielding a total of more than 20,000 recordings.
Researchers then listened to the recordings and identified the conversations as trivial small talk or substantive discussions. In addition, the volunteers completed personality and well-being assessments.
An analysis of the recordings revealed some very interesting findings.
Greater well-being was related to spending less time alone and more time talking to others: The happiest participants spent 25 percent less time alone and 70 percent more time talking than the unhappiest participants.
In addition to the difference in the amount of social interactions happy and unhappy people had, there was also a difference in the types of conversations they took part in: The happiest participants had twice as many substantive conversations and one third as much small talk as the unhappiest participants.
These findings suggest that the happy life is social and conversationally deep rather than solitary and superficial.
The researchers surmise that — though the current findings cannot identify the causal direction — deep conversations may have the potential to make people happier.
They note, “Just as self-disclosure can instill a sense of intimacy in a relationship, deep conversations may instill a sense of meaning in the interaction partners.”
The findings are reported in the latest issue of Psychological Science, http://www.psychologicalscience.orgViva 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 latest 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.

Say you want to create a new habit, whether it’s taking more exercise, eating more healthily or writing a blog post every day, how often does it need to be performed before it no longer requires Herculean self control?
Clearly it’s going to depend on the type of habit you’re trying to form and how single-minded you are in pursuing your goal. But are there any general guidelines for how long it takes before behaviours become automatic?
Ask Google and you’ll get a figure of somewhere between 21 and 28 days. In fact there’s no solid evidence for this number at all. The 21 day myth may well come from a book published in 1960 by a plastic surgeon. Dr Maxwell Maltz noticed that amputees took, on average, 21 days to adjust to the loss of a limb and he argued that people take 21 days to adjust to any major life changes.
Unless you’re in the habit of sawing off your own arm, this is not particularly relevant.
Doing without thinking
Now, however, there is some psychological research on this question in a paper recently published in the European Journal of Social Psychology. Phillippa Lally and colleagues from University College London recruited 96 people who were interested in forming a new habit such as eating a piece of fruit with lunch or doing a 15 minute run each day Lally et al. (2009). Participants were then asked daily how automatic their chosen behaviours felt. These questions included things like whether the behaviour was ‘hard not to do’ and could be done ‘without thinking’.
When the researchers examined the different habits, many of the participants showed a curved relationship between practice and automaticity of the form depicted below (solid line). On average a plateau in automaticity was reached after 66 days. In other words it had become as much of a habit as it was ever going to become.
This graph shows that early practice was rewarded with greater increases in automaticity and gains tailed off as participants reached their maximum automaticity for that behaviour.
Although the average was 66 days, there was marked variation in how long habits took to form, anywhere from 18 days up to 254 days in the habits examined in this study. As you’d imagine, drinking a daily glass of water became automatic very quickly but doing 50 sit-ups before breakfast required more dedication (above, dotted lines). The researchers also noted that:
- Missing a single day did not reduce the chance of forming a habit.
- A sub-group took much longer than the others to form their habits, perhaps suggesting some people are ‘habit-resistant’.
- Other types of habits may well take much longer.
No small change
What this study reveals is that when we want to develop a relatively simple habit like eating a piece of fruit each day or taking a 10 minute walk, it could take us over two months of daily repetitions before the behaviour becomes a habit. And, while this research suggests that skipping single days isn’t detrimental in the long-term, it’s those early repetitions that give us the greatest boost in automaticity.
Unfortunately it seems there’s no such thing as small change: the much-repeated 21 days to form a habit is a considerable underestimation unless your only goal in life is drinking glasses of water.
