Mean girls and queen bees: Females threatened by social exclusion will reject others first

2011-02-28
(Press-News.org) Many studies have suggested that males tend to be more physically and verbally aggressive than females. According to a new study, to be published in Psychological Science, a journal of the Association for Psychological Science, it may not be the case that women are less competitive than men—they may just be using a different strategy to come out ahead. Specifically, women may rely more on indirect forms of aggression, such as social exclusion.

To investigate how men and women respond when faced with a social threat, psychological scientist Joyce F. Benenson of Emmanuel College and Harvard University, along with her colleagues, asked volunteers to play a game against two hypothetical partners in which they accumulated points for money. Volunteers had the option of playing by themselves (compete-alone option), forming an alliance with one of the opponents, or cooperating with both of the opponents (in this strategy, they would avoid competition but split profits three ways).

During the game, some of the volunteers were confronted with the possibility of social exclusion. When the compete-alone option was described, volunteers were told that by selecting this option, they would "run the risk of being excluded by the two others." The description of the alliance option included the statement, "If you and your partner win, then the third player will be excluded and will not win any points."

The results revealed that when volunteers received the standard instructions—without the social exclusion clauses—there was no difference among male and female volunteers in the number of times they chose to form an alliance with another player. However, when the exclusionary instructions were used, female participants chose the alliance option more often than did male volunteers.

"As their primary competitive strategy to combat any social threat, females may attempt to form an exclusionary alliance, whereas males may endeavor to unilaterally and directly dominate an opponent," the authors write. Women may be more sensitive than men to social exclusion, and when they feel threatened by the prospect of being left out, a woman's first response may be to socially exclude a third party.

Preemptive social exclusion appears to be a valuable strategy for women because it allows them to protect their relationships by keeping an outsider at bay. Benenson points out that this may require a re-evaluation of presumed sex differences in competitiveness. She comments, "The same-sex social worlds of boys and girls and men and women then differ in that females have to worry about alienating others, whereas males worry about getting beaten up."

Rare gene glitch may hold clues for schizophrenia -- NIH-funded study

Rare gene glitch may hold clues for schizophrenia -- NIH-funded study
2011-02-28
Scientists are eyeing a rare genetic glitch for clues to improved treatments for some people with schizophrenia – even though they found the mutation in only one third of 1 percent of patients. In the study, funded in part by the National Institutes of Health, schizophrenia patients were 14 times more likely than controls to harbor multiple copies of a gene on Chromosome 7. The mutations were in the gene for VIPR2, the receptor for vasoactive intestinal peptide (VIP) – a chemical messenger known to play a role in brain development. An examination of patients' blood ...

GPs take more than a month to record ovarian cancer diagnosis in one in 10 cases

2011-02-28
Family doctors can take more than a month to record ovarian cancer, once diagnosed by a specialist, in one in 10 cases, indicates research published in the launch issue of the new online journal BMJ Open. Ovarian cancer was also incorrectly or prematurely classified in 11% of cases, the data show. The authors base their findings on the "free text" data available in patient records, which are submitted to the General Practice Research Database (GPRD). The GPRD contains long term anonymised medical data on more than four million patients on the lists of a representative ...

Most 'locked-in syndrome' patients say they are happy

2011-02-28
Most "locked-in syndrome" patients say they are happy, and many of the factors reported by those who say they are unhappy can be improved, suggest the results of the largest survey of its kind, published in the launch issue of the new online journal BMJ Open. The findings are likely to challenge the perception that these patients can no longer enjoy quality of life and are candidates for euthanasia or assisted suicide, say the authors. The research team quizzed 168 members of the French Association for Locked in Syndrome on their medical history and emotional state, ...

2011-02-28
SAN ANTONIO (Feb. 24, 2011) — Mouse models are yielding important clues about the nature of autism spectrum disorders, which impact an estimated one in 110 children in the U.S.[1] In labs at the UT Health Science Center San Antonio, researchers are studying strains of mice that inherently mimic the repetitive and socially impaired behaviors present in these disorders. Georgianna Gould, Ph.D., research assistant professor of physiology in the Graduate School of Biomedical Sciences, is eyeing the role that serotonin plays in autism spectrum disorders. Serotonin is known ...

Antioxidants in pecans may contribute to heart health and disease prevention

2011-02-28
Loma Linda, California – A new research study from Loma Linda University (LLU) demonstrates that naturally occurring antioxidants in pecans may help contribute to heart health and disease prevention; the results were published in the January 2011 issue of The Journal of Nutrition. Pecans contain different forms of the antioxidant vitamin E—known as tocopherols, plus numerous phenolic substances, many of them with antioxidant abilities. The nuts are especially rich in one form of vitamin E called gamma-tocopherols. The findings illustrate that after eating pecans, gamma-tocopherol ...

Researcher lists more than 4,000 components of blood chemistry

2011-02-28
After three years of exhaustive analysis led by a University of Alberta researcher, the list of known compounds in human blood has exploded from just a handful to more than 4,000. "Right now a medical doctor analyzing the blood of an ailing patient looks at something like 10 to 20 chemicals," said U of A biochemist David Wishart. "We've identified 4,229 blood chemicals that doctors can potentially look at to diagnose and treat health problems." Blood chemicals, or metabolites, are routinely analyzed by doctors to diagnose conditions like diabetes and kidney failure. ...

Redesign of US donor-liver network could boost transplants by several hundred per year

Redesign of US donor-liver network could boost transplants by several hundred per year
2011-02-28
PITTSBURGH—A redesign of the nation's donor-liver distribution network developed by University of Pittsburgh researchers could result in several hundred more people each year receiving the transplants they need. The team reports in the journal INFORMS Management Science that donor livers currently are doled out to 11 national regions that evolved with little regard for geography and demographics, an arrangement that prevents many livers from getting to prospective recipients in time. The Pitt researchers instead trimmed the network down to six regions that better account ...

New study shows ability of transgenic fungi to combat malaria and other bug-borne diseases

2011-02-28
COLLEGE PARK, Md. - New findings by a University of Maryland-led team of scientists indicate that a genetically engineered fungus carrying genes for a human anti-malarial antibody or a scorpion anti-malarial toxin could be a highly effective, specific and environmentally friendly tool for combating malaria, at a time when the effectiveness of current pesticides against malaria mosquitoes is declining. In a study published in the February 25 issue of the journal Science, the researchers also say that this general approach could be used for controlling other devastating ...

Multiple childbirth linked to increased risk of rare, aggressive 'triple-negative' breast cancer

2011-02-28
SEATTLE – Full-term pregnancy has long been associated with a reduced risk of breast cancer, but a new study finds that the more times a woman gives birth, the higher her risk of "triple-negative" breast cancer, a relatively uncommon but particularly aggressive subtype of the disease. Conversely, women who never give birth have a 40 percent lower risk of such breast cancer, which has a poorer prognosis than other types of breast cancer and doesn't respond to hormone-blocking therapies such as tamoxifen. These findings, from a study led by Amanda Phipps, Ph.D., a postdoctoral ...
