Women and body dissatisfaction: Does sexual orientation make a difference?

In this study, heterosexual (n=95) and nonheterosexual (n=84) women were asked to rate figure drawings and computer-generated images of women that varied in body fat, waist-to-hip ratio, and breast size in terms of self, ideal, and cultural ideal; discrepancy indices, indicating body dissatisfaction, were created for each body aspect. Nonheterosexual women had significantly higher body mass indices (BMIs) than heterosexual women, but when the effects of BMI were controlled, participants evidenced similar perceptions of their bodies, their ideal bodies, and the female cultural ideal, as well as similar levels of body dissatisfaction for body fat, waist-to-hip ratio, and breast size. The results of this study suggest that being a member of a society that highly values a thin, curvaceous, relatively large-breasted body puts women, regardless of sexual orientation, at risk for body dissatisfaction.

Sleep debt and depression in female college students.

The objective of the study was to evaluate relationships between sleep habits and depressive symptoms. Pilot study data were collected about sleep schedules, related factors and depression in female college students to find whether their sleep schedules correlate with affective symptoms. In the subsequent main study, similar information was collected under more controlled conditions.

Pilot study of relationship between fertility risk and bargaining.

Competition for resources to support a healthy pregnancy and later offspring was likely very important for ancestral women. Therefore, it was predicted that women evolved a propensity for intrasexual competition over resources during times of their highest conception risk. To investigate this hypothesis, women played a series of ultimatum games, bargaining games that test participants' willingness to share a monetary stake.

Inference of mental states in patients with Alzheimer's disease.

Introduction: The ability to determine what someone thinks or knows often requires an individual to infer the mental state of another person, an ability typically referred to as one's "theory of mind". The present study tests this ability in patients with mild-to-moderate Alzheimer's disease (AD).

Methods: Three theory of mind tests and three standardised neuropsychological tests were presented to a group of patients with AD (n = 25) and a group of healthy elderly controls (n = 15).

Inference of beliefs and emotions in patients with Alzheimer's disease.

The present study compared 20 patients with mild to moderate Alzheimer's disease with 20 older controls (ages 69-94 years) on their ability to make inferences about emotions and beliefs in others. Six tasks tested their ability to make 1st-order and 2nd-order inferences as well as to offer explanations and moral evaluations of human action by appeal to emotions and beliefs. Results showed that the ability to infer emotions and beliefs in 1st-order tasks remains largely intact in patients with mild to moderate Alzheimer's.
