Group work is the name of the game in many companies. The thinking is that workers will learn more and help each other when they are put into groups composed of people with a variety of expertise. But does this always happen? Some recent research suggests that it may not … at least not always.

In the Thoroughman laboratory, volunteers play games on a computer screeen using a robotic arm so that Thoroughman and his colleagues can study how people learn motor skills.Central to being human is the ability to adapt: We learn from our mistakes. Previous theories of learning have assumed that the size of learning naturally scales with the size of the mistake. But now biomedical engineers at Washington University in St. Louis have shown that people can use alternative strategies: Learning does not necessarily scale proportionally with error.

Deanna Barch (center) discusses brain imaging techniques used in the experiment, which used the functional magnetic resonance imaging (fMRI) machine (shown at right).When encouraged to use memorization strategies commonly employed by healthy individuals, people with schizophrenia can be helped to remember information just as well as their healthy counterparts, a process that in itself seems to spur a normalization of memory-related activities in the brains of people with schizophrenia, suggests new research from Washington University in St. Louis.

Adolescence can be a trying time for the whole family.Adolescence is characterized by dramatic physical changes as young people grow from childhood to physical maturity. During adolescence, we gain 50 percent of our adult weight and 20 percent of adult height while going through puberty and developing the ability to reproduce. With so many physical and emotional changes occurring at the same time, Washington University adolescent medicine researchers at St. Louis Children’s Hospital say it’s important for parents to be prepared for change. They also must be ready to listen to their children at any time, day or night, and do as much as possible to stay involved in their lives.

Adults of all ages are being invited to become volunteer participants in research conducted by faculty and students connected with the Aging and Development Program of the Department of Psychology in Arts & Sciences. Some of the studies deal with practical problems, others with basic abilities such as thinking, memory and perception. Current projects range […]

Are humans inherently good? The prevailing view in popular and scientific literature is that humans and animals are genetically driven to compete for survival, thus making all social interaction inherently selfish. According to this line of reasoning, known as sociobiology, even seemingly unselfish acts of altruism merely represent a species’ strategy to survive and preserve its genes. But Robert W. Sussman, Ph.D., a professor of anthropology in Arts & Sciences at Washington University in St. Louis, argues that this is a narrow and simplistic view of evolutionary theory that fails to explain many aspects of sociality among mammals in general and primates in particular. In “The Origins and Nature of Sociality,” a new book Sussman co-edited, he and other researchers challenge the proponents of sociobiology. “The ‘selfish gene’ hypothesis is inadequate,” Sussman says.

A psychologist at Washington University in St. Louis says that people who suffer from social anxiety disorders can receive help through cognitive behavior therapy.Citing statistics that show that many people fear public speaking more than death, comedian Jerry Seinfeld once joked that if you’re at a funeral, you’re better off in the casket than doing the eulogy. But for people who suffer from social anxiety disorders, one of which is public speaking, it’s no laughing matter. These people’s personal lives and careers can be sidelined by fear of certain social situations, such as speaking with a boss or authority figure, making telephone calls or attending parties. The good news is that these disorders are highly treatable through cognitive behavior therapy, in particular, group therapy, according to a psychologist at Washington University in St. Louis.

Photo by Joe Angeles/WUSTL PhotoAre gamblers impulsive?Why do people engage in behaviors they know are harmful to them in the long run? Why do we give in to that incredible chocolate cake even though we’re trying to lose weight and stay fit? The answer, suggests a recent study on the psychology of gambling and impulsive behavior, is a simple economic phenomenon known as discounting. While good health may be its own reward, research suggests that the value of that reward diminishes as it’s delayed; and the longer it’s delayed, the less it controls your present behavior. Although gamblers may deserve their reputations as notorious risk-takers, they often do better than non-gamblers at delaying gratification to maximize long-term rewards.
