New Findings…Group Settings Can Diminish Expressions of Intelligence

Research led by scientists at the Virginia Tech Carilion Research Institute found that small-group dynamics — such as jury deliberations, collective bargaining sessions, and cocktail parties — can alter the expression of IQ in some susceptible people. “You may joke about how committee meetings make you feel brain dead, but our findings suggest that they may make you act brain dead as well,” said Read Montague, director of the Human Neuroimaging Laboratory and Computational Psychiatry Unit at the Virginia Tech Carilion Research Institute, who led the study.

The scientists used functional magnetic resonance imaging (fMRI) to investigate how the brain processes information about social status in small groups and how perceptions of that status affect expressions of cognitive capacity.

“We started with individuals who were matched for their IQ,” said Montague. “Yet when we placed them in small groups, ranked their performance on cognitive tasks against their peers, and broadcast those rankings to them, we saw dramatic drops in the ability of some study subjects to solve problems. The social feedback had a significant effect.”

“Our study highlights the unexpected and dramatic consequences even subtle social signals in group settings may have on individual cognitive functioning,” said lead author Kenneth Kishida, a research scientist with the Virginia Tech Carilion Research Institute. “And, through neuroimaging, we were able to document the very strong neural responses that those social cues can elicit.”

The researchers recruited subjects from two universities and administered a standard test to establish baseline IQ. The results were not viewed until after a series of ranked group IQ tasks, during which test takers, in groups of five, received information about how their performances compared to those of the other group members.

Although the test subjects had similar baseline IQ scores — a mean of 126, compared to the national average of 100 — they showed a range of test performance results after the ranked group IQ tasks, revealing that some individuals’ expressed IQ was affected by signals about their status within a small group.

The researchers wanted to know what was happening in the brain during the observed changes in IQ expression. The subjects were divided into two groups based on the results of their final rank — the high performers, who scored above the median, and the low performers, who scored at or below the median. Two of every group of five subjects had their brains scanned using fMRI while they participated in the task.

Among the researchers’ findings:

1. Dynamic responses occurred in multiple brain regions, especially the amygdala, the prefrontal cortex, and the nucleus accumbens — regions believed to be involved in emotional processing, problem solving, and reward and pleasure, respectively.

2. All subjects had an initial increase in amygdala activation and diminished activity in the prefrontal cortex, both of which corresponded with a lower problem-solving ability.

3. By the end of the task, the high-performing group showed a decreased amygdala activation and an increased prefrontal cortex activation, both of which were associated with an increased ability to solve more difficult problems.

4. Positive changes in rank were associated with greater activity in the bilateral nucleus accumbens, which has traditionally been linked to learning and has been shown to respond to rewards and pleasure.

5. Negative changes in rank corresponded with greater activity in the dorsal anterior cingulate cortex, consistent with a response to conflicting information.

6. Neither age nor ethnicity showed a significant correlation with performance or brain responses. A significant pattern did emerge along gender lines, however. Although male and female participants had the same baseline IQ, significantly fewer women (3 of 13) were in the high-performing group and significantly more (10 of 13) fell into the low-performing group.

“We don’t know how much these effects are present in real-world settings,” Kishida said. “But given the potentially harmful effects of social-status assignments and the correlation with specific neural signals, future research should be devoted to what, exactly, society is selecting for in competitive learning and workplace environments. By placing an emphasis on competition, for example, are we missing a large segment of the talent pool? Further brain imaging research may also offer avenues for developing strategies for people who are susceptible to these kinds of social pressures.”

“This study tells us the idea that IQ is something we can reliably measure in isolation without considering how it interacts with social context is essentially flawed,” said coauthor Steven Quartz, a professor of philosophy in the Social Cognitive Neuroscience Laboratory of Caltech. “Furthermore, this suggests that the idea of a division between social and cognitive processing in the brain is really pretty artificial. The two deeply interact with each other.”

“So much of our society is organized around small-group interactions,” said Kishida. “Understanding how our brains respond to dynamic social interactions is an important area of future research. We need to remember that social dynamics affect not just educational and workplace environments, but also national and international policy-making bodies, such as the U.S. Congress and the United Nations.”

The research appears in the Jan. 23, 2012 issue of the journalPhilosophical Transactions of the Royal Society B in the article, “Implicit signals in small group settings and their impact on the expression of cognitive capacity and associated brain responses,” by Kenneth Kishida; Dongni Yang, a former postdoctoral researcher in the Department of Neuroscience at Baylor College of Medicine; Karen Hunter Quartz, a director of research in the Graduate School of Education and Information Studies of the University of California, Los Angeles; Steven Quartz; and Read Montague, corresponding author, who is also a professor of physics at Virginia Tech. The research was supported by grants from the Wellcome Trust and the Kane Family Foundation to Montague and the National Institutes of Health to Montague and Kishida.

Museum to Visitors: Please Do Touch, for Scientific Purposes

Photo Credit: The Walters Art Museum, Modest Venus, or Venus Pudica, a 10.5-inch bronze statuette cast around 1500 by an anonymous Italian artist, is one of the pieces replicated for museum goers to caress for science at an exhibition in Baltimore.

Newswise — It’s the first rule at any art museum: Do not touch the artifacts. Except at this museum and at this one time.

At the “Touch and the Enjoyment of Sculpture: Exploring the Appeal of Renaissance Statuettes” exhibition — at the Walters Art Museum in Baltimore through April 15 — visitors are invited to disregard that decree and to hold, stroke and even caress the pieces.

In fact, handling the objects d’arts — replicas of famous 16th century statuettes held by the Walters — is one of the reasons for the exhibition, explains neuroscientist Steven Hsiao, a researcher at the Johns Hopkins Brain Science Institute. The institute is partnering with the Walters on the show, the fourth in a series of projects between the museum and Johns Hopkins.

“We’re challenging people to think about why physical contact with works of art can be so satisfying,” says Hsiao, whose work includes exploring many aspects of humans’ sense of touch. “In fact, as people browse the exhibition, we will be asking them to react to what they are seeing and feeling.”

The installation incorporates 12 works of art from the Walters collection, along with 22 replicas for visitors to touch and rate, providing data for ongoing research.

The project melds the research interests of Hsiao, who specializes in many facets of touch, and those of Joaneath Spicer, the Walters’ curator of Renaissance and Baroque art, who studies the Renaissance penchant for collecting and commissioning small statuettes and other luxury goods that were satisfying to touch and handle.

But the special appeal of this exhibition lies in the opportunity to join in comparative experiments with the statuettes (well, the replicas, actually).

“We’ll be asking visitors to handle them and to tell us what sculptures they prefer and to rate how they like sculptures that have been modified in their shape and texture. This exhibition allows us to dissect why some objects feel better than others” Hsiao says.

Visitors will register these preferences, and other reactions, on Apple iPads, and visitors will be able to see a dynamic display of their responses. The data will be used in Hsaio’s and Spicer’s research on tactile aesthetics. (Visitors will not be handling the original 16th century artwork; they will only be permitted to touch replica art exclusively fashioned for the show.)

The Walters Art Museum is open from 10 a.m. to 5 p.m. Wednesdays through Sundays and is located at 600 North Charles St. in Baltimore.

Imagine That: How You Envision Others Says a Lot About You in Real Life

Newswise — Quick, come up with an imaginary co-worker.

Did you imagine someone who is positive, confident and resourceful? Who rises to the occasion in times of trouble? If so, then chances are you also display those traits in your own life, a new study finds.

University of Nebraska-Lincoln researchers have found that study participants who conjured positive imaginary co-workers contributed more in the actual workplace, both in job performance and going above and beyond their job descriptions to help others.

The results showed that your perceptions of others – even ones that are made up – says a lot about what kind of person you really are, said Peter Harms, UNL assistant professor of management and the study’s lead author.

Imagining coworkers instead of reporting on how you perceive your actual coworkers produces more accurate ratings of having a positive worldview, he said, because it strips away the unique relational baggage that one may have with the people they know.

“When you make up imaginary peers, they are completely a product of how you see the world,” Harms said. “Because of that we can gain better insight into your perceptual biases. That tells us a lot about how you see the world, how you interpret events and what your expectations of others are.”

The study consisted of hundreds of working adults in a range of fields, Harms said. It specifically targeted their “psychological capital,” a cluster of personality characteristics associated with the ability to overcome obstacles and the tendency to actively pursue one’s goals.

After asking participants to conjure up imaginary workers in a series of hypothetical situations, they were then asked to make ratings of the individuals they imagined on a wide range of characteristics.

Those who envisioned workers as engaging in proactive behaviors or readily rebounding from failures were actually happier and more productive in their real-life work, the researchers found.

Researchers have long acknowledged the benefits of having a positive mindset, but getting an accurate assessment has always been difficult because people are typically unwilling or unable to make accurate self-appraisals, Harms said.

Through the use of projective storytelling, the UNL researchers were able to predict real-life work outcomes above and beyond other established measures.

“We’ve known that workplace relations are a self-fulfilling prophecy for some time,” Harms said. “If a manager believes that their workers are lazy and incompetent, they will elicit those patterns in their employees.

“It’s hard to be motivated and enthusiastic for someone you know doesn’t think of you very highly. But most people don’t want to disappoint someone who sincerely believes in them.”

The study, which will appear in a forthcoming edition of theJournal of Organizational Behavior, was co-authored by Fred Luthans, the George Holmes Distinguished Professor of Management at UNL.

We May Be Less Happy, but Our English Language Isn’t

Newswise — “If it bleeds, it leads,” goes the cynical saying with television and newspaper editors. In other words, most news is bad news and the worst news gets the big story on the front page.

So one might expect the New York Times to contain, on average, more negative and unhappy types of words — like “war,” ” funeral,” “cancer,” “murder” — than positive, happy ones — like “love,” “peace” and “hero.”

Or take Twitter. A popular image of what people tweet about may contain a lot of complaints about bad days, worse coffee, busted relationships and lousy sitcoms. Again, it might be reasonable to guess that a giant bag containing all the words from the world’s tweets — on average — would be more negative and unhappy than positive and happy.

But new research shows just the opposite.

“English, it turns out, is strongly biased toward being positive,” said Peter Dodds, an applied mathematician at the University of Vermont.

The UVM team’s study “Positivity of the English Language,” is presented in the Jan. 11 issue of the journal PLoS ONE.

This new study complements another study the same Vermont scientists presented in the Dec. 7 issue of PLoS ONE, “Temporal Patterns of Happiness and Information in a Global Social Network.”

That work attracted wide media attention showing that average global happiness, based on Twitter data, has been dropping for the past two years.

Combined, the two studies show that short-term average happiness has dropped — against the backdrop of the long-term fundamental positivity of the English language.

In the new study, Dodds and his colleagues gathered billions of words from four sources: twenty years of the New York Times, the Google Books Project (with millions of titles going back to 1520), Twitter and a half-century of music lyrics.

“The big surprise is that in each of these four sources it’s the same,” says Dodds. “We looked at the top 5,000 words in each, in terms of frequency, and in all of those words you see a preponderance of happier words.”

Or, as they write in their study, “a positivity bias is universal,” both for very common words and less common ones and across sources as diverse as tweets, lyrics and British literature.

Why is this? “It’s not to say that everything is fine and happy,” Dodds says. “It’s just that language is social.”

In contrast to traditional economic theory, which suggests people are inherently and rationally selfish, a wave of new social science and neuroscience data shows something quite different: that we are a pro-social storytelling species. As language emerged and evolved over the last million years, positive words, it seems, have been more widely and deeply engrained into our communications than negative ones.

“If you want to remain in a social contract with other people, you can’t be a…,” well, Dodds here used a word that is rather too negative to be fit to print — which makes the point.

This new work adds depth to the Twitter study that the Vermont scientists published in December that attracted attention from NPR, Time magazine and other media outlets.

“After that mild downer story, we can say, ‘But wait — there’s still happiness in the bank,” Dodds notes. “On average, there’s always a net happiness to language.”

Both studies drew on a service from Amazon called Mechanical Turk. On this website, the UVM researchers paid a group of volunteers to rate, from one to nine, their sense of the “happiness” — the emotional temperature — of the 10,222 most common words gathered from the four sources. Averaging their scores, the volunteers rated, for example, “laughter” at 8.50, “food” 7.44, “truck” 5.48, “greed” 3.06 and “terrorist” 1.30.

The Vermont team — including Dodds, Isabel Kloumann, Chris Danforth, Kameron Harris, and Catherine Bliss — then took these scores and applied them to the huge pools of words they collected. Unlike some other studies — with smaller samples or that elicited strong emotional words from volunteers — the new UVM study, based solely on frequency of use, found that “positive words strongly outnumber negative words overall.”

This seems to lend support to the so-called Pollyanna Principle, put forth in 1969, that argues for a universal human tendency to use positive words more often, easily and in more ways than negative words.

Of course, most people would rank some words, like “the,” with the same score: a neutral 5. Other words, like “pregnancy,” have a wide spread, with some people ranking it high and others low. At the top of this list of words that elicited strongly divergent feelings: “profanities, alcohol and tobacco, religion, both capitalism and socialism, sex, marriage, fast foods, climate, and cultural phenomena such as the Beatles, the iPhone, and zombies,” the researchers write.

“A lot of these words — the neutral words or ones that have big standard deviations — get washed out when we use them as a measure,” Dodds notes. Instead, the trends he and his team have observed are driven by the bulk of English words tending to be happy.

If we think of words as atoms and sentences as molecules that combine to form a whole text, “we’re looking at atoms,” says Dodds. “A lot of news is bad,” he says, and short-term happiness may rise and and fall like the cycles of the economy, “but the atoms of the story — of language — are, overall, on the positive side.”

Some Like it Hot: Popular Yoga Style Cranks up the Heat

What You Need to Know to Prevent Injuries

Photo Credit, Hospital for Special Surgery. People practicing hot yoga should take certain precautions, said certified yoga instructor Diana Zotos of Hospital for Special Surgery.

Newswise — Yoga is one of the hottest fitness trends and a style known as “hot yoga” is gaining in popularity.

Hot yoga refers to yoga practiced in a heated environment, with the room temperature generally reaching 90 to 105 degrees. The theory behind it is that hot yoga helps the body to sweat out toxins while allowing the practitioner to safely achieve deeper poses. Bikram is a common form of hot yoga.

Almost 16 million Americans practice some form of yoga, according to a 2008 study in the Yoga Journal.

While the practice can offer health benefits and a sense of well-being, people practicing hot yoga, especially beginners, should take certain precautions, according to Diana Zotos, a certified yoga instructor and physical therapist in the Rehabilitation Department at Hospital for Special Surgery in Manhattan.

“Yoga of any type is physically challenging, and the heated environment of hot yoga makes the practice especially demanding,” Zotos says. “The heat makes people feel as if they can stretch deeper into poses and can give them a false sense of flexibility. This can lead to muscle strains or damage to the joint, including ligaments and cartilage.”

Zotos says people over 40 who have never done Bikram yoga may be at greater risk of injury, and she recommends they familiarize themselves with it prior to trying a class. “There are many books and videos that describe this style and can demonstrate the poses and techniques,” she says. “Since classes are constructed of the same 26 poses, people can become familiar with them beforehand.”

Beginners should keep in mind that poses will require a certain level of leg, core and upper body strength, as well as balance, according to Zotos. People should also have a tolerance for stretching and moderate flexibility in their legs and spine.

“The heat factor also puts more strain on the heart and challenges endurance. That being said, people should be of good cardiovascular health; have healthy hip, knee, spine and shoulder joints; shouldn’t have balance or neurological issues; and should have a general tolerance for excessive heat,” she advises.

Zotos has these additional tips:

• Be well-prepared. Bring a mat and towel, and
wear shorts and a tank top. If possible, bring a buddy. It can be more fun and less intimidating if you take your first class with a friend.
• Make sure you drink plenty of fluids well before class (but not coffee or soda). Don’t eat anything too heavy (more than 200 calories) two to three hours prior to class.
• Make sure the studio and teachers have a good reputation. Ask about their experience and credentials. The teacher should be certified in Bikram or another form of yoga.
• Try to arrive early. This way you can introduce yourself and speak with the instructor, pick a good spot in the studio to set up your mat and get comfortable with your surroundings and the heat.
• Start slowly and learn the basics. Never push yourself to the point of pain while stretching or assuming a position.
• Listen to your body. Stop at the first sign of discomfort. If you are extremely fatigued, take a break. Do not try yoga poses beyond your experience or comfort level.
• Don’t get discouraged if you can’t reach a pose. It’s not a competition.
• Ask questions if you’re not sure how to perform a pose.
• If you get dizzy, lightheaded, overheated or experience chest pain, STOP immediately. Seek medical assistance if necessary.

Anyone who questions whether hot yoga is safe for them should consult their physician, Zotos says. “If you have sensitivity to heat, if you’ve ever had heat stroke or tend to get fatigued, dizzy or dehydrated quickly, you should ask your doctor before starting hot yoga. Anyone with osteoarthritis, any rheumatologic arthritis, pain in muscles or a joint, or any kind of previous injury should check with their doctor.”

Zotos says it’s especially important that anyone who has hypertension, low blood pressure or heart disease check with their cardiologist before trying hot yoga.

Ring in a New Healthier You in 2012!

Newswise — BOSTON— With the start of a new year, Dana-Farber Cancer Institute experts are encouraging people to ring in new healthy habits and offer a number of free and low-cost strategies to help people maintain good health and possibly reduce various cancer risks.

Get moving!
Staying fit and healthy can be as simple as lacing up a pair of sneakers and going for a walk. Moderate to intensive aerobic exercise, according to studies, can reduce the risk of recurrence of several cancers, including colon and breast.

“You don’t have to be a marathon runner, but the more you exercise, typically the greater the beneficial effect,” says Jeffrey Meyerhardt, MD, MPH, a Dana-Farber gastrointestinal cancer specialist.

Here are some inexpensive ways to workout, but consult a doctor first.
– Using the stairs rather than an elevator.
– Walking or riding a bike rather than driving.
– Taking an exercise break or quick walk at work.
– Using a stationary bicycle or treadmill while watching TV.

Color Your World…and your shirt?
It doesn’t cost anything to walk by the cookie aisle and into a store’s produce section. And, taking that little detour can provide many health benefits. A diet low in processed sugars, red meat and calories, but high in fruits and vegetables and loaded with antioxidants is one of the simplest ways to help maintain a healthy weight and reduce the risk of certain cancer.
The overall key is to look for colorful produce like pomegranates, tomatoes, eggplant, grapes, cherries, and turnip. The brighter and richer the pigment, the higher the level of nutrients.
“In the nutrition world, we like to say if it comes from the ground and it stains your shirt, you want to be eating it,” says Stephanie Meyers, MS, RD/LDN, a nutritionist at Dana-Farber.

Skip that cocktail
Limiting alcohol consumption can save money and it may lower the risk of developing some cancers. Dana-Farber researchers found that women who consume one alcoholic drink a day may increase their risk for breast cancer. “Women need to consider the possible effects of alcohol on breast cancer risk when weighing the risks and benefits of alcohol consumption,” says Wendy Chen, MD, PhD, a breast cancer expert. “Our findings indicate that in some women, even modest levels of alcohol consumption may elevate their risk of breast cancer.”

Save money and lives – quit smoking
Buying cigarettes and other tobacco products can really take a bite out of a budget. Kicking the habit can result in both a healthier lifestyle and significant financial savings.
According to the American Cancer Society, smoking is the most preventable cause of death in the United States. It also causes more than 80 percent of all cases of lung cancer and increases the risk of oral, throat, pancreatic, uterine, bladder, and kidney cancers.

“Even though there have been many recent advances in lung cancer treatments, the most effective way to eradicate lung cancer is to prevent it from ever happening,” explains Bruce Johnson, MD, director of Dana-Farber’s Lowe Center for Thoracic Oncology. Johnson emphasizes that it is never too late to quit.

People who stop and remain nonsmokers for at least 10 to 20 years can cut their risk of developing lung cancer in half.
– Plan the quit day
– Follow the four D’s: Deep breaths, Drink lots of water, Do something to avoid focusing on cravings, Delay reaching for a cigarette – the urge will pass.
– Avoid triggers: Get rid of cigarettes, lighters, matches, and ashtrays.

Sunscreen ‘applies’ year round
Sunscreen shouldn’t be packed away after summer ends. Skin can be exposed to harmful rays all year long. Snow, ice and water can all reflect the ultraviolet (UV) radiation that causes sunburn, which, in turn increases the risk of developing skin cancer. Some experts say winter sports enthusiasts can face just as much risk of getting sunburn as summer sunbathers. Dana-Farber experts remind to protect year round.
– Wear sunscreen, lip balm and makeup with an SPF of 15 or higher.
– Use UV-blocking eye protection, especially for skiing.
– In a tropical setting, wear a broad brimmed hat and UV-blocking sunglasses.
– Avoid excessive exposure to the sun, especially between 10 a.m. and 4 p.m. when the sun is at its strongest.

Don’t forget your dentist
Visiting the dentist is not just about clean and healthy teeth. Dentists also are on the front lines of detecting cancer in the mouth. Research shows more than half of all smokeless tobacco users have non-cancerous or pre-cancerous lesions in their mouth. In addition to the increased risk of cancer, smoking and chewing tobacco erodes teeth and gums. “The treatment for this type of head and neck cancer can be a radical and deforming surgery,” warns Robert Haddad, MD, disease center leader of the head and neck oncology program at Dana-Farber. He stresses, “The changes in the cells never go away once they happen. So don’t start using tobacco and if you have, get help to stop.”

Low Vitamin D Levels Linked to Depression

DALLAS – Jan. 5, 2012 – Low levels of vitamin D have been linked to depression, according to UT Southwestern Medical Center psychiatrists working with the Cooper Center Longitudinal Study. It is believed to be the largest such investigation ever undertaken.

Low levels of vitamin D already are associated with a cavalcade of health woes from cardiovascular diseases to neurological ailments. This new study – published in Mayo Clinic Proceedings – helps clarify a debate that erupted after smaller studies produced conflicting results about the relationship between vitamin D and depression. Major depressive disorder affects nearly one in 10 adults in the U.S.

“Our findings suggest that screening for vitamin D levels in depressed patients – and perhaps screening for depression in people with low vitamin D levels – might be useful,” said Dr. E. Sherwood Brown, professor of psychiatry and senior author of the study, done in conjunction with The Cooper Institute in Dallas. “But we don’t have enough information yet to recommend going out and taking supplements.”

UT Southwestern researchers examined the results of almost 12,600 participants from late 2006 to late 2010. Dr. Brown and colleagues from The Cooper Institute found that higher vitamin D levels were associated with a significantly decreased risk of current depression, particularly among people with a prior history of depression. Low vitamin D levels were associated with depressive symptoms, particularly those with a history of depression, so primary care patients with a history of depression may be an important target for assessing vitamin D levels. The study did not address whether increasing vitamin D levels reduced depressive symptoms.

The scientists have not determined the exact relationship – whether low vitamin D contributes to symptoms of depression, whether depression itself contributes to lower vitamin D levels, or chemically how that happens. But vitamin D may affect neurotransmitters, inflammatory markers and other factors, which could help explain the relationship with depression, said Dr. Brown, who leads the psychoneuroendocrine research program at UT Southwestern.

Vitamin D levels are now commonly tested during routine physical exams, and they already are accepted as risk factors for a number of other medical problems: autoimmune diseases; heart and vascular disease; infectious diseases; osteoporosis; obesity; diabetes; certain cancers; and neurological disorders such as Alzheimer’s and Parkinson’s diseases, multiple sclerosis, and general cognitive decline.

Investigators used information gathered by the institute, which has 40 years of data on runners and other fit volunteers. UT Southwestern has a partnership with the institute, a preventive medicine research and educational nonprofit located at the Cooper Aerobics Center, to develop a joint scientific medical research program aimed at improving health and preventing a wide range of chronic diseases. The institute maintains one of the world’s most extensive databases – known as the Cooper Center Longitudinal Study – that includes detailed information from more than 250,000 clinic visits that has been collected since Dr. Kenneth Cooper founded the institute and clinic in 1970.

Other researchers involved in the study were Dr. Myron F. Weiner, professor of psychiatry and neurology and neurotherapeutics; Dr. David S. Leonard, assistant professor of clinical sciences; lead author MinhTu T. Hoang, student research fellow; Dr. Laura F. DeFina, medical director of research at The Cooper Institute; and Benjamin L. Willis, epidemiologist at the institute.

Research Indicates Humble People are More Likely to Lend a Helping Hand

Newswise — Humble people are more likely to offer time to someone in need than arrogant people are, according to findings by Baylor University researchers published online inThe Journal of Positive Psychology.

“The findings are surprising because in nearly 30 years of research on helping behavior, very few studies have shown any effect of personality variables on helping,” said lead author Jordan LaBouff, Ph.D., a lecturer in psychology at the University of Maine, who collaborated on the research while a doctoral candidate at Baylor. “The only other personality trait that has shown any effect is agreeableness, but we found that humility predicted helping over and above that.”

In most cases, a person’s decision to help someone in need is influenced by temporary personal or situational factors such as time pressure, number of bystanders, momentary feelings of empathy or a person’s own distress, said Wade C. Rowatt, Ph.D., associate professor of psychology and neuroscience in Baylor’s College of Arts & Sciences, who led the study and co-authored the article.

“The research indicates that humility is a positive quality with potential benefits,” Rowatt said. “While several factors influence whether people will volunteer to help a fellow human in need, it appears that humble people, on average, are more helpful than individuals who are egotistical or conceited.”

The research involved three studies of college students:

• In Study 1, participants who reported themselves as humble also generally reported that they were helpful, even when other important personality factors, such as agreeableness, were statistically controlled. Because people can easily under-report or exaggerate their humility to create a desired impression, the subsequent studies used an implicit measure of humility.

• In Study 2, students evaluated a recording they were told might be broadcast later on the campus radio station. The recording described a fellow student who had injured a leg and could not attend class regularly. Each participant was asked how many hours over the next three weeks they would be willing to meet with the injured student to provide aid. Humble persons offered more time to help than less humble ones.

• In Study 3, both implicit and self-report measures of humility were used. Students were asked to associate as quickly as possible traits that applied to themselves. Among stimulus words in the humility association test were humble, modest, tolerant, down to earth, respectful and open-minded. Stimulus words in the arrogance portion included arrogant, immodest, egotistical and conceited. Again, humility was associated with amount of time offered to help a student in need, especially when pressure to help was low.

“Our discovery here is that the understudied trait of humility predicts helpfulness,” Rowatt said. “Important next steps will be to figure out whether humility can be cultivated and if humility is beneficial in other contexts, such as scientific and medical advancements or leadership development.”

Other research collaborators are Baylor doctoral candidate Megan K. Johnson and Jo-Ann Tsang, Ph.D., associate professor of psychology and neuroscience at Baylor.

Top 5 Winter Activities that Land You In The Emergency Room

Newswise — The first day of winter is Wednesday, December 21, and many states are bracing for a season of snow and ice. Broken bones from snowboarding and sledding top the list of common visits to the Emergency Department (ED) during the winter months. According to the Centers for Disease Control and Prevention, one-quarter of all emergency hospital visits are attributed to snowboarding accidents, and half of all cases were for broken bones and sprains.

“Chicagoans embrace winter with gusto largely because of the great love for hockey, sledding and ice skating,” said Gottlieb Memorial Hospital orthopaedic surgeon Daryl O’Connor, who formerly cared for U.S. Olympic ski and winter sports athletes in Salt Lake City, Utah. Dr. O’Connor is board certified in orthopaedic surgery and now specializes in sports medicine in the Orthopaedic Department at Gottlieb Memorial Hospital, part of Loyola University Health System.

Here are Dr. O’Connor’s evaluations of the top five winter sports:

1. Sledding – “More than 700,000 injuries are reported each year in the United States due to sledding. More than 30 percent are head injuries, caused by collisions,” O’Connor said.

2. Hockey – “Lacerations, as well as neck, shoulder and knee injuries are common in hockey. Many injuries are caused through contact with another player, the ice, a puck or actual skate blade,” he said.

3. Ice skating – “Injuries to the wrist as well as head and neck are most common and most injuries are caused by falls,” he said.

4. Snowboarding – “Wrist and elbow injuries are caused by falls on outstretched hands,” he said.

5. Skiing – “Knees really take a pounding and injury is often caused by extreme twisting force-propelled by the skis,” he said.

Snitching on Skitching

“This is not even a sport; it’s just being foolish,” said Dr. O’Connor of the practice in neighborhoods of daredevil teens grabbing a car’s rear bumper and sliding on their feet, or being pulled by ropes on inner tubes or sleds through icy streets. “In addition to broken bones, neck and shoulder injuries, young people can suffer fatal head trauma. Please, resist the skitch at all costs.”

Resolution Solution: How Making a Plan Can Help You Meet New Year’s Goals

When making New Year’s resolutions this year, committing to a specific plan for when and where you are going to accomplish each goal will make you more likely to succeed, says psychologist E.J. Masicampo. In a recent study published in the Journal of Personality and Social Psychology, he found that committing to a specific plan to accomplish a goal not only makes it more likely to be done, but also gets it off your mind so you can think about other things.

Newswise — When making New Year’s resolutions this year, committing to a specific plan for when and where you are going to accomplish each goal will make you more likely to succeed, says a Wake Forest University psychology professor.

In a recent study published in the Journal of Personality and Social Psychology, Assistant Professor E.J. Masicampo found that committing to a specific plan to accomplish a goal not only makes it more likely to be done, but also gets it off your mind so you can think about other things.

“Once a plan is made, we can stop thinking about that one goal,” says Masicampo, who studies goal setting and will power. “This frees our minds to focus on other tasks or simply enjoy the current moment.”

But, not just any plan will work, he says. “The ones that work specify exactly what you are going to do, including when and where you are going to do it.”

He describes four essential elements of a successful plan:

1. Specifies exactly what you’re going to do and in what situation (where and when)
2. Is under your control and not dependent on someone else’s actions
3. Includes specific opportunities to meet the goal in situations likely to occur
4. Focuses on a goal you are motivated to accomplish

Most importantly, he says, “You have to picture yourself carrying out your plan. That’s where the power of the plans lie, in imagining yourself completing the tasks.”

Imagining doing something has a similar effect on the brain as really doing it. Since keeping resolutions is often about creating new habits, this gives you a head start on developing the desired behavior.

“It’s all about making a habit out of the goal. A plan is like creating a habit ahead of time,” says Masicampo, “before you have actually done anything.”

This sort of planning works best for less complex goals. He suggests breaking down New Year’s resolutions into steps, so the overall goal can more likely be attained. Someone with a goal to lose weight, for example, should make “if, then” plans for specific situations that can help them accomplish the overall goal. “An ‘if, then’ plan pre-decides how you will act in a given situation,” Masicampo says. For example, if you visit a particular restaurant, then you will order a salad instead of the cheeseburger and onion rings. The plan gives you a cue to act. If you commit to the plan, all you have to do is wait for the cue. When the situation arises, you just do it because you already know what you’re going to do.

“Making a plan is like setting an alarm because you don’t have to think about it until the alarm sounds and then you’ll act.”

A typical person is juggling as many as 15 different goals at one time. Planning makes it possible to stop thinking about one goal until the planned time and place.

“Every time you make a plan, you tether a goal to a future context, and it can stop floating around in your head and distracting you from your other goals,” Masicampo says.

So, with good planning, this may be the year to check more than one New Year’s resolution off the list.
