Childhood ADHD predicts risky sexual behavior in young adulthood.

This study compared young adults (ages 18 to 26) with and without childhood attention deficit hyperactivity disorder (ADHD) on self-reported risky sexual behaviors. Participants were 175 men with childhood ADHD and 111 demographically similar men without ADHD in the Pittsburgh ADHD Longitudinal Study (PALS). Childhood ADHD predicted earlier initiation of sexual activity and intercourse, more sexual partners, more casual sex, and more partner pregnancies.

A representative measure of psychological aggression and its severity.

Surveys of psychological aggression have been plagued by a variety of conceptual and measurement problems. A new measure was devised to more systematically cover a full range of psychologically aggressive actions; to include items for each dimension/category at a milder, moderate, and severe level; to be applicable to dating as well as marital relationships; and to utilize items that were broader in nature to capture all instances of particular types of psychological aggression. Three hundred and eighty-three college students rated the 51 items as to their degree of "psychological abusiveness.

Bias in spatial memory: a categorical endorsement.

Two experiments investigated how angular estimates reflect bias as a function of response mode, geometric plane of variation, number of implicit categories, memory load and intervening task conditions. In Experiment 1, participants made motor and verbal estimates of incline and azimuth from memory. Estimates in both response modes showed signs of bias predicted by a single-category adaptation of Huttenlocher et al.

Verbal coercive sexual behavior among college students.

Coercive sexual behavior exists at alarming rates on college campuses. Researchers attempting to identify factors related to sexual coercion have primarily investigated either the coercing college male or the coerced college female, independent of relationship factors. The present study investigated the prevalence of verbal sexual coercion, the beliefs and attitudes of sexually coercive and noncoercive men, and the differences in affective states between groups and at different stages of relationship development.

Changes in the muscarinic cholinergic receptors in the hippocampus of rats exposed to ethyl alcohol during the brain growth spurt.

Rats were exposed to ethanol from postnatal day 4 to day 10, using an artificial rearing procedure. One group received ethanol administered by a cyclic regimen, which resulted in high peak blood ethanol concentrations (BACs). Another group received the same daily dose of ethanol using a regimen which resulted in stable, moderate BACs.
