Soldiers Who Desecrate the Dead See Themselves as Hunters

By Good German on May 21, 2012 in News 6

Modern day soldiers who mutilate enemy corpses or take body-parts as trophies are usually thought to be suffering from the extreme stresses of battle. But, research funded by the Economic and Social Research Council (ESRC) shows that this sort of misconduct has most often been carried out by fighters who viewed the enemy as racially different from themselves and used images of the hunt to describe their actions.

“The roots of this behaviour lie not in individual psychological disorders,” says Professor Simon Harrison who carried out the study, “but in a social history of racism and in military traditions that use hunting metaphors for war. Although this misconduct is very rare, it has persisted in predictable patterns since the European Enlightenment. This was the period when the first ideologies of race began to appear, classifying some human populations as closer to animals than others.”

European and North American soldiers who have mutilated enemy corpses appear to have drawn racial distinctions of this sort between close and distant enemies.

The Trust Molecule

By majestic on April 29, 2012 in News 11

Paul J. Zak, author of The Moral Molecule: The Source of Love and Prosperity, asks “Could a single molecule—one chemical substance—lie at the very center of our moral lives?” in the Wall Street Journal:

Research that I have done over the past decade suggests that a chemical messenger called oxytocin accounts for why some people give freely of themselves and others are coldhearted louts, why some people cheat and steal and others you can trust with your life, why some husbands are more faithful than others, and why women tend to be nicer and more generous than men. In our blood and in the brain, oxytocin appears to be the chemical elixir that creates bonds of trust not just in our intimate relationships but also in our business dealings, in politics and in society at large.

Known primarily as a female reproductive hormone, oxytocin controls contractions during labor…

It’s Not Only Beeps and Vibrations: Learn How to Focus From Within

By Larry D. Rosen on April 10, 2012 in News 4

Recently my research team observed nearly 300 middle school, high school and university students studying something important for a mere 15 minutes in their natural environments. We were interested in whether they could maintain focus and, if not, what might be distracting them. Every minute we noted exactly what they were doing, whether they were studying, if they were texting or listening to music or watching television in the background, and if they had a computer screen in front of them and what websites were being visited.

The results were startling. First, these students were only able to focus and stay on task for an average of three minutes at a time and nearly all of their distractions came from technology. [By the way, other researchers have found similar attention spans with computer programmers and medical students.] The major culprit: their smartphone and their laptop were providing constant interruptions. We also looked at whether these distractors might predict who was a better student.… Read the rest

Young Drug Users Ingest ‘Mystery White Powders’

By majestic on March 15, 2012 in News 5

A poll by The Guardian and Mixmag magazine reveals that in many cases people have no idea what drugs they are taking:

A fifth of young drug users admit to taking “mystery white powders” without any idea what they contain, according to an international Guardian survey that reveals the extent of reckless behaviour among a new generation of high-risk drug takers.

The poll of 15,500 people by the Guardian and Mixmag magazine also found that more respondents in the UK and US admitted taking cannabis than either tobacco or energy drinks. Those who defined themselves as clubbers were more likely to take ecstasy than smoke cigarettes…

Cellphone Use Linked To Selfish Behavior

From ScienceDaily:

Though cellphones are usually considered devices that connect people, they may make users less socially minded, finds a recent study from the University of Maryland’s Robert H. Smith School of Business.

Marketing professors Anastasiya Pocheptsova and Rosellina Ferraro, with graduate student, Ajay T. Abraham, conducted a series of experiments on test groups of cellphone users. The findings appear in their working paper, “The Effect of Mobile Phone Use on Prosocial Behavior.”

Prosocial behavior, as defined in the study, is action intended to benefit another person or society as a whole.

The researchers found that after a short period of cellphone use the subjects were less inclined to volunteer for a community service activity when asked, compared to the control-group counterparts. The cell phone users were also less persistent in solving word problems — even though they knew their answers would translate to a monetary donation to charity.

Psychopathy: A Misunderstood Personality Disorder

By Good German on December 22, 2011 in News 12

Via ScienceDaily:

Psychopathic personalities are some of the most memorable characters portrayed in popular media today. These characters, like Patrick Bateman from American Psycho, Frank Abagnale Jr. from Catch Me If You Can and Alex from A Clockwork Orange, are typically depicted as charming, intriguing, dishonest, guiltless, and in some cases, downright terrifying.

But scientific research suggests that psychopathy is a personality disorder that is widely misunderstood.”Psychopathy tends to be used as a label for people we do not like, cannot understand, or construe as evil,” notes Jennifer Skeem, Professor of Psychology and Social Behavior at the University of California, Irvine. Skeem, Devon Polaschek of Victoria University of Wellington, Christopher Patrick of Florida State University, and Scott Lilienfeld of Emory University are the authors of a new monograph focused on understanding the psychopathic personality that will appear in the December issue of Psychological Science in the Public Interest, a journal of the Association for Psychological Science.

Was Darwin Wrong About Emotions?

By Good German on December 18, 2011 in News 15

Via ScienceDaily:

Contrary to what many psychological scientists think, people do not all have the same set of biologically “basic” emotions, and those emotions are not automatically expressed on the faces of those around us, according to the author of a new article published in Current Directions in Psychological Science, a journal published by the Association for Psychological Science.

This means a recent move to train security workers to recognize “basic” emotions from expressions might be misguided.”What I decided to do in this paper is remind readers of the evidence that runs contrary to the view that certain emotions are biologically basic, so that people scowl only when they’re angry or pout only when they’re sad,” says Lisa Feldman Barrett of Northeastern University, the author of the new paper.

The commonly-held belief is that certain facial muscle movements (called expressions) evolved to express certain mental states and prepare the body to react in stereotyped ways to certain situations.

Why Do People Defend Unjust, Inept, and Corrupt Systems?

By Good German on December 15, 2011 in News 12

Detail from Corrupt Legislation. Mural by Elihu Vedder (1896).

Via ScienceDaily:

Why do we stick up for a system or institution we live in — a government, company, or marriage — even when anyone else can see it is failing miserably? Why do we resist change even when the system is corrupt or unjust?

A new article in Current Directions in Psychological Science, a journal published by the Association for Psychological Science, illuminates the conditions under which we’re motivated to defend the status quo — a process called “system justification.”System justification isn’t the same as acquiescence, explains Aaron C. Kay, a psychologist at Duke University’s Fuqua School of Business and the Department of Psychology & Neuroscience, who co-authored the paper with University of Waterloo graduate student Justin Friesen. “It’s pro-active. When someone comes to justify the status quo, they also come to see it as what should be.”

Reviewing laboratory and cross-national studies, the paper illuminates four situations that foster system justification: system threat, system dependence, system inescapability, and low personal control …

A Vaccination Against Social Prejudice

By Good German on December 10, 2011 in News 9

Via ScienceDaily:

Evolutionary psychologists suspect that prejudice is rooted in survival: Our distant ancestors had to avoid outsiders who might have carried disease. Research still shows that when people feel vulnerable to illness, they exhibit more bias toward stigmatized groups. But a new study in Psychological Science, a journal published by the Association for Psychological Science suggests there might be a modern way to break that link.

“We thought if we could alleviate concerns about disease, we could also alleviate the prejudice that arises from them,” says Julie Y. Huang of the University of Toronto, about a study she conducted with Alexandra Sedlovskaya of Harvard University; Joshua M. Ackerman of the Massachusetts Institute of Technology; and Yale University’s John A. Bargh. The group found that the sense of security derived through measures such as vaccination and hand washing can reduce bias against “out” groups, from immigrants to the obese.

The Neuroeconomics Revolution

By Good German on November 30, 2011 in News 2

The left/right paradigm is coming to a quicker end than I thought. Robert Schiller writes at Al Jazeera:

Economics is at the start of a revolution that is traceable to an unexpected source: medical schools and their research facilities. Neuroscience — the science of how the brain, that physical organ inside one’s head, really works — is beginning to change the way we think about how people make decisions. These findings will inevitably change the way we think about how economies function. In short, we are at the dawn of “neuroeconomics”.

Efforts to link neuroscience to economics have occurred mostly in just the last few years, and the growth of neuroeconomics is still in its early stages. But its nascence follows a pattern: revolutions in science tend to come from completely unexpected places. A field of science can turn barren if no fundamentally new approaches to research are on the horizon.
