Self-affirmation may break down resistance to medical screening
People resist medical screening, or don't call back for the results, because they don't want to know they're sick or at risk for a disease. But many illnesses, such as HIV/AIDS and cancer, have a far a better prognosis if they're caught early. How can health care providers break down that resistance?

Faster progress through puberty linked to behavior problems
Children who go through puberty at a faster rate are more likely to act out and to suffer from anxiety and depression, according to a study by researchers at Penn State, Duke University and the University of California, Davis. The results suggest that primary care providers, teachers and parents should look not only at the timing of puberty in relation to kids' behaviour problems, but also at the tempo of puberty -- how fast or slow kids go through puberty.

Study shows how context dictates what we believe we see
Scientists at UCL (University College London) have found the link between what we expect to see, and what our brain tells us we actually saw. The study reveals that the context surrounding what we see is all important – sometimes overriding the evidence gathered by our eyes and even causing us to imagine things which aren’t really there.

New Insights Into the Nature of Pride as a Social Function
Pride has perplexed philosophers and theologians for centuries, and it is an especially paradoxical emotion in American culture. We applaud rugged individualism, self-reliance and personal excellence, but too much pride can easily tip the balance toward vanity, haughtiness and self-love. Scientists have also been perplexed by this complex emotion, because it is so unlike primary emotions like fear and disgust.

There are limited gender differences in cognitive function than previously thought. Income does affect cognitive performance but less than expected when only healthy children are considered. And while basic cognitive skills steadily improve in middle childhood, they then seem to level off questioning the idea of a burst of brain development in adolescence.

Virtual racing seems to lead to aggressive driving
Psychologists have taken the âmedia primingâ effects of popular video console and PC-based games on the road, finding that virtual racing seems to lead to aggressive driving and a propensity for risk taking. Extending prior findings on how aggressive virtual-shooter games increase aggression-related thoughts, feelings and behaviors, researchers at Munich's Ludwig-Maximilians University and the Allianz Center for Technology found that of 198 men and women, those who play more virtual car-racing games were more likely to report that they drive aggressively and get in accidents. Less frequent virtual racing was associated with more cautious driving.

Mice that couldn't be dissuaded from the object of their attention by a piece of sweet, crunchy cereal may help researchers find new treatments and cures for human disorders like autism and Parkinson's disease. For the first time, a psychiatric test for monitoring many human mental abnormalities has been adapted for use in mice, according to researchers at Purdue University, University of California-Davis and Justus-Liebig University in Giessen, Germany. The test involves the ability to switch attention from one task to another, a skill often impaired in people with autism and similar illnesses.

How behaviors can be changed or created
UC Riverside researchers have made a major leap forward in understanding how the brain programs innate behavior. The discovery could have future applications in engineering new behaviors in animals and intelligent robots. Innate or "instinctive" behaviors are inborn and do not require learning or prior experience to be performed. Examples include courtship and sexual behaviors, escape and defensive maneuvers, and aggression. Using the common fruit fly as a model organism, the researchers found through laboratory experiments that the innate behavior is initiated by a "command" hormone that orchestrates activities in discrete groups of peptide neurons in the brain. Peptide neurons are brain cells that release small proteins to communicate with other brain cells and the body.

People more likely to help others they think are 'like them'
Feelings of empathy lead to actions of helping but only between members of the same group according to a recent study. The research, led by Stefan Stürmer of the University of Kiel, is presented in the article "Empathy-Motivated Helping: The Moderating Role of Group Membership." The article discusses two different studies, one using a real-world, intercultural scenario and the other using a mixture of people with no obvious differences besides gender. Researchers concluded that, while all the people felt empathy for someone in distress, they only tended to assist if the needy person was viewed as a member of their own "in-group."

Avoiding Punishment Is Its Own Reward
For my now-departed, wonderful old cat named Bear, life didn't get any better than raw shrimp. Seeing the little white package emerge from the fridge always caught his attention, but what set him into high-shriek mode was the sound of shrimp being peeled under running waterhe knew culinary bliss was at hand. Bear's behavior was perfectly in keeping with the theory of reinforcement learning: through instrumental conditioning, animals learn to choose responses associated with producing favorable outcomes and avoiding unpleasant onestypically by learning to associate two normally unrelated stimuli. The shrimp reward reinforced associations between stimulus (the sound of peeling and washing, rather than the sight of shrimp) and response (expectant wailing).

Does psychological treatment for adult sex offenders work?
Psychological treatment for adult sex offenders can reduce reoffending rates but does not provide a cure, say experts in an editorial in this week's BMJ. Sexual offending is a public health issue and a social problem. Psychological treatment is widely used and is often mandated in the sentencing decision for sexual offenders. But just how effective are psychological treatment programmes? Are they too readily accepted uncritically? Specialists in psychology and criminology review the evidence from published studies. In an analysis of randomised controlled trials on behavioural treatments, they found that most studies were too small to be informative, although statistically significant improvements were recorded across some groups of offenders.

Broca's area also organizes behavioral hierarchies
Researchers have discovered that Broca's area in the brain--best known as the region that evolved to manage speech production--is a major "executive" center in the brain for organizing hierarchies of behaviors. Such planning ability, from cooking a meal to organizing a space mission, is considered one of the hallmarks of human intelligence. The researchers found that Broca's area--which lies on the left side of the brain about in the temple region--and its counterpart on the right side activate when people are asked to organize plans of action. They said their finding of the general executive function of Broca's area could explain its key role in language production. Importantly, the researchers found that this executive function of these cortical regions was distinct from the organization of temporal sequences of actions.

Men infer sexual interest before women do
In the latest issue of Psychology of Women Quarterly, researchers find that men rate themselves and the women they just interacted with higher on sexual traits, such as flirtatiousness, than women rate men. The authors find that after a five-minute conversation with a stranger of the opposite gender, men were more likely to interpret ambiguous or friendly behavior as indicating sexual interest. "The findings suggest that men generally think in more sexual terms than women," the authors explain.

Vision, hearing and touch all develop during such critical periods, while other senses, such as the olfactory system, maintain lifelong plasticity.

Older people with stronger cognitive skills walk at a safer pace
Psychologists wanting to help old people safely cross the street and otherwise ambulate around this busy world have found that from age 70 and up, safe walking may require solid "executive control" (which includes attention) and memory skills. For the old, slow gait is a significant risk factor for falls, many of which result in disabling fractures, loss of independence or even death. The finding may help explain why cognitive problems in old age, including dementia, are associated with falls. Cognitive tests could help doctors assess risk for falls; conversely, slow gait could alert them to check for cognitive impairment. The findings are in the March issue of Neuropsychology, which is published by the American Psychological Association (APA).
