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.

What do football and alcohol have to do with being a man?
Men across the world will be getting the pints in and staring at the big screen this month as the World Cup kicks off in Germany. But what do football and alcohol have to do with being a man? A recent psychological study by the University of Sussex reveals that the roaring crowds may be drinking their way through the game in an effort to compensate for not being man enough to play in it.

'Executive' monkeys influenced by other executives, not subordinates
When high-ranking monkeys are shown images of other monkeys glancing one way or the other, they more readily follow the gaze of other high-ranking monkeys, Duke University Medical Center neurobiologists have discovered. By contrast, they tend to ignore glance cues from low-status monkeys; while low-status monkeys assiduously follow the gaze of all other monkeys.

Morphine addiction and the tendency to explore linked
A team of researchers from the UAB has found experimental evidence in rats showing a link between addiction to morphine and the tendency to explore perseveringly. This is the first time a direct relationship has been found without other psychological characteristics, such as anxiousness, that might affect results. Published in Behavioural Brain Research, the results of this study are useful for planning preventative strategies in the risk population.

New study shows how self-prophecies may help
By now, most of us have probably forgotten about our New Year's resolutions. But there's still hope: New research from the March 2006 issue of the Journal of Consumer Research shows that when people predict that they will do a socially good deed (such as recycling), the chances of them actually doing the good deed increases.

Loneliness might be Explained by Genes
Heredity helps determine why some adults are persistently lonely, research co-authored by psychologists at the University of Chicago shows. Working with colleagues in The Netherlands, the scholars found about 50 percent of identical twins and 25 percent of fraternal twins shared similar characteristics of loneliness. Research on twins is a powerful method to study the impact of heredity because twins raised together share many of the same environmental influences as well as similar genes, thus making it easier to determine the role of genetics in development. "An interesting implication of this research is that feelings of loneliness may reflect an innate emotional response to stimulus conditions over which an individual may have little or no control," the research team writes in the article, "Genetic and Environmental Contributors to Loneliness in Adults: The Netherlands Twin Register Study" published in the current issue of the journal Behavior Genetics. Psychologists had previously thought loneliness was primarily caused by shyness, poor social skills, or inability to form strong attachments with other people. Scholars are becoming increasingly interested in the role loneliness plays in health. Other work by John Cacioppo, the Tiffany & Margaret Blake Distinguished Service Professor in Psychology at the University of Chicago and a member of the research team, shows that loneliness is a risk factor for heart disease. Loneliness is also at the base of a number of emotional conditions, such as self-esteem, mood, anxiety, anger and sociability.
