TIME Magazine on the nature of masculinity

TIME Magazine reports:

Manhood is a social status, something a guy earned historically, through brutal tests of physical endurance or other risky demonstrations of toughness that mark the transition from boyhood to manhood. But while that masculinity is hard-won, it can be easily lost.

Once earned, men have to continue proving their worth through manly action. In modern society, that may no longer mean, say, killing the meatiest wooly mammoth, but there are equivalent displays of masculinity: earning a decent living or protecting one’s family. One misstep — losing a job, for instance, or letting someone down — and that gender identity slips away.

The phenomenon helps explain why men are so touchy about their masculinity. Women don’t have the same problem, of course. Womanhood is largely seen as something innate, immutable: girls become women through puberty; once achieved, womanhood sticks.

In a series of studies, psychologists Jennifer K. Bosson and Joseph A. Vandello at the University of South Florida decided to probe this idea further. Specifically, they wanted to know, do modern men still use physical action and aggression to prove their manhood?

The psychology of belief and perception

Writing for Wired.com, Jonah Lehrer reviews research on belief and perception:

It turns out that the human mind is a marvelous information filter, adept at blocking out those facts that contradict what we’d like to believe. Just look at this experiment, which was done in the late 1960’s, by the cognitive psychologists Timothy Brock and Joe Balloun. They played a group of people a tape-recorded message attacking Christianity. Half of the subjects were regular churchgoers while the other half were committed atheists. To make the experiment more interesting, Brock and Balloun added an annoying amount of static – a crackle of white noise – to the recording. However, they allowed listeners to reduce the static by pressing a button, so that the message suddenly became easier to understand. Their results were utterly predicable and rather depressing: the non-believers always tried to remove the static, while the religious subjects actually preferred the message that was harder to hear.

New research on the relationship between sleep and weight

Reuters reports:

Sleep deprivation makes the day drag and appears to put a drag on metabolism too, causing the body to use less energy, according to a European study.

The results, reported in the American Journal of Clinical Nutrition, add to evidence that sleep loss can promote weight gain — not just by boosting hunger but also by slowing the rate at which calories are burned.

The study suggests that getting plenty of sleep might prevent weight gain, said Christian Benedict of Uppsala University in Sweden, who led the study.

Researchers confirm existence of genes linked to depression

The Financial Times reports:

Scientists have for the first time confirmed a specific genetic link to depression, according to new evidence published in the American Journal of Psychiatry on Monday.

The discovery, made independently by research teams in the UK and US, is expected to lead to a better biological understanding of the condition and eventually to more effective antidepressants.
