Meta-analyses of sex differences in physical aggression to heterosexual partners and in its physical consequences are reported. Women were slightly more likely (d = -.05) than men to use one or more act of physical aggression and to use such acts more frequently. Men were more likely (d = .15) to inflict an injury, and overall, 62% of those injured by a(More)
Research on testosterone-behavior relationships in humans is assessed in relation to a version of the challenge hypothesis, originally proposed to account for testosterone-aggression associations in monogamous birds. Predictions were that that testosterone would rise at puberty to moderate levels, which supported reproductive physiology and behavior. Sexual(More)

Animal studies show clear evidence for a causal link between testosterone and aggression. This review assesses studies involving androgens, principally testosterone, and human aggression. Evidence for a possible effect of prenatal androgens is inconclusive. In adults, higher testosterone levels are found in groups selected for high levels of aggressiveness.(More)
Over the last decade, researchers have found that girls may be just as aggressive as boys when manipulative forms of aggression, such as gossiping and spreading rumors, are included. These forms of aggression are known by 3 different names: indirect aggression, relational aggression, and social aggression. This review examines their commonalities and(More)
Meta-analyses are reported of sex differences in acts of physical aggression to heterosexual partners, derived from the Conflict Tactics Scale (CTS) [J Marriage Fam 8 (1979) 75], using methods based on standardized mean differences, and on odds ratios. Women were more likely than men to throw something at the other, slap, kick, bite, or punch, and hit with(More)
In Study 1, a 40-item questionnaire measuring instrumental and expressive beliefs about aggression, along a five-point scale, was developed. It was based on a 20-item questionnaire (Campbell, Muncer & Coyle, 1992) where the two alternatives were forced choices for each item. In the present study the two sets of beliefs were only moderately correlated(More)
This study sought to both replicate and considerably extend the findings of Johnson (1999) that there are two distinct subgroups of physical aggression within relationships: intimate terrorism and common couple violence. The present sample consisted of women residing at Women's Aid shelters and their partners (N=86), male and female students (N=208), men(More)
OBJECTIVES The effect of testosterone (T) on sexual function in men is well established. However, less is known about its effects on cognitive function. The aim of this study is to investigate the relationship between T levels and sex-typed cognitive abilities in both eugonadal and hypogonadal men. DESIGN A single-blind placebo-controlled design was(More)
A 40-item questionnaire based on reactions following human bereavement was used to investigate the occurrence of grief following death of a pet in a sample of 88 people. Items indicating initial numbness or disbelief, preoccupation with the loss, a loss of part of themselves and being drawn towards reminders were endorsed by half to four-fifths of the(More)
