Study: Off-Campus College Party Hosts Drink More Than Attendees

COLUMBUS, Ohio – On any given weekend, at least 10 percent of students at a single college could be hosting a party, and on average, party hosts who live off campus are drinking more and engaging in more alcohol-related problem behaviors than are the students attending their bashes, research suggests.

In contrast, hosts of parties held on campus tend to drink less than do the students attending their gatherings, according to the study. (more…)

A Scarcity of Women Leads Men to Spend More, Save Less

*University of Minnesota Research Finds Sex Ratios Influence Financial Decisions*

MINNEAPOLIS / ST. PAUL — The perception that women are scarce leads men to become impulsive, save less, and increase borrowing, according to new research from the University of Minnesota’s Carlson School of Management.

“What we see in other animals is that when females are scarce, males become more competitive. They compete more for access to mates,” says Vladas Griskevicius, an assistant professor of marketing at the Carlson School and lead author of the study. “How do humans compete for access to mates? What you find across cultures is that men often do it through money, through status and through products.” (more…)

Helping Your Fellow Rat: Rodents Show Empathy-Driven Behavior

*Rats free trapped companions, even when given choice of chocolate instead*

The first evidence of empathy-driven helping behavior in rodents has been observed in laboratory rats that repeatedly free companions from a restraint, according to a new study by University of Chicago neuroscientists.

The observation, published today in Science, places the origin of pro-social helping behavior earlier in the evolutionary tree than previously thought. Though empathetic behavior has been observed anecdotally in non-human primates and other wild species, the concept had not previously been observed in rodents in a laboratory setting. (more…)

Violent Video Games Reduce Brain Response to Violence and Increase Aggressive Behavior, University of Missouri Study Finds

*Parental moderation encouraged for children*

COLUMBIA, Mo. – Scientists have known for years that playing violent video games causes players to become more aggressive.  The findings of a new University of Missouri (MU) study provide one explanation for why this occurs: the brains of violent video game players become less responsive to violence, and this diminished brain response predicts an increase in aggression.

“Many researchers have believed that becoming desensitized to violence leads to increased human aggression. Until our study, however, this causal association had never been demonstrated experimentally,” said Bruce Bartholow, associate professor of psychology in the MU College of Arts and Science. (more…)

Contact With Dads Drops When Women Ovulate

*Evidence of evolutionary protection against inbreeding in women?*

Through an innovative use of cell phone records, researchers at UCLA, the University of Miami and Cal State, Fullerton, have found that women appear to avoid contact with their fathers during ovulation. 

“Women call their dads less frequently on these high-fertility days and they hang up with them sooner if their dads initiate a call,” said Martie Haselton, a UCLA associate professor of communication in whose lab the research was conducted.  (more…)

Researchers Find Cancer News May Contribute to Confusion About Cancer

New research from North Carolina State University shows that most online news stories about cancer contain language that likely contributes to public uncertainty about the disease – a significant finding, given that at least one-third of Americans seek health information online.

“Previous studies show that more than 100 million Americans seek health information online, and that their findings affect their health decisions,” says Dr. Kami Kosenko, an assistant professor of communication at NC State and co-author of a paper describing the study. “But, while people facing uncertainty about cancer issues are likely to seek out additional information, we’ve found that there are features of the information they’re seeking that may actually exacerbate the uncertainty.” (more…)
