What would large women think if a dress sold for lower cost to women of smaller sizes?

Common sense says this would turn them off.

But swimmers react well to items claimed to improve speed if they know the product is given away free to Olympic swimmers.

If you perceive the person getting the good deal as being smarter than you, you are okay with it. You are even more likely to pay full price.

This post is about an article by Schacter et al (pdf) regarding how the constructiveness of memories may crucially be due to the need to simulate future scenarios. But before I go to the main course, I would like to touch upon a starter: Jeff Hawkins Heirarchical Temporla Memory (HTM) hypothesis.

Psychiatric researchers at The Zucker Hillside Hospital campus of The Feinstein Institute for Medical Research have uncovered evidence of a new gene that appears to increase the risk of developing schizophrenia, a disorder characterized by distorted thinking, hallucinations and a reduced ability to feel normal emotions..

Working in conjunction with researchers at the Harvard Medical School Partners Center for Genetics and Genomics in Boston, MA, the Zucker Hillside team utilized a cutting-edge technology called whole genome association (WGA) to search the entire human genome in 178 patients with schizophrenia and 144 healthy individuals.

Playground roughhousing has long been a tradition of children and adolescents, much to the chagrin of several generations of parents who worry that their child will be hurt or worse, become accustom to violence and aggression. But animal research may paint a different portrait of rough and tumble play; one that suggests that social and emotional development may rely heavily on such peer interaction.

Research by the World Health Organization (WHO) has suggested that the course and symptomatic expression of schizophrenia is relatively more benign in developing societies. However, a new study from Current Anthropology challenges this assumption, comparing biological and cultural indicators of schizophrenia in urban, Western societies with study data from the island of Palau, which has one of the highest rates of schizophrenia diagnosis in the world today.

“A 1% average worldwide population prevalence of schizophrenia is routinely interpreted in the medical literature as implying a uniform distribution,” write Roger J. Sullivan (California State University, Sacramento), John S. Allen (University of Southern California), and Karen L. Nero (University of Canterbury, New Zealand).

Sexual victimization can mean several things -- verbal coercion to have sex with an intimate partner, rape by a stranger, a woman fondled in a bar or forced intercourse when a woman is too intoxicated to consent or object.

Researchers at the University at Buffalo's Research Institute on Addictions report that 18 percent of young women recruited into a study experienced sexual victimization in a two-year period. Victimization was defined as unwanted sexual contact, verbally coerced sex, rape or attempted rape. Among this group, the majority (approximately 66 percent) stated that their victimization was perpetrated by an intimate partner.

ver wonder why some women seem to be more ill-tempered than others? University of Pittsburgh researchers have found that behaviors such as anger, hostility and aggression may be genetic, rooted in variations in a serotonin receptor gene. Indrani Halder, Ph.D., of the Cardiovascular Behavioral Medicine Program at the University of Pittsburgh, will present the findings today at the American Psychosomatic Society's Annual Meeting, held in Budapest, Hungary.

Previous studies have associated the hormone serotonin with anger and aggression in both humans and animals and have shown that increased serotonin activity is related to a decrease in angry and aggressive behaviors.

Omega-3 fatty acids, found in fatty fish like salmon, are associated with increased grey matter volume in areas of the brain commonly linked to mood and behavior according to a University of Pittsburgh study.

Findings will be presented today by Sarah M. Conklin, Ph.D., postdoctoral scholar at the Cardiovascular Behavioral Medicine Program in the department of psychiatry at the University of Pittsburgh, at the American Psychosomatic Society’s Annual Meeting, held in Budapest, Hungary.

Animal research has shown that raising omega-3 intake leads to structural brain changes. In a separate study presented by Dr.

A few days ago on the Dean Edell radio show, I’m told, Dean Edell told his listeners that nicotine patches don’t cause any addiction problems; people just don’t get addicted to them. To anyone who has read The Shangri-La Diet this will sound eerily familiar: Dr. William Jacobs, a professor of psychiatry and addiction researcher at the University of Florida, told me that no one gets addicted to unflavored sugar water, although lots of people get addicted to Coke, Pepsi, and other forms of flavored sugar water.

Speed daters who romantically desired most of their potential partners were rejected quickly and overwhelmingly, according to a new Northwestern University study.

Conventional wisdom has long taught that one of the best ways to get someone to like you is to make it clear that you like them. Now researchers have discovered that this law of reciprocity is in dire need of an asterisk in the domain of romantic attraction.
