Behavioral effects of cyclic changes in serotonin during the human menstrual cycle.

Many cyclic changes during the menstrual cycle (temperature, depression, motor activity, pain sensitivity, etc.) are closely paralleled by changes in brain serotonin level. These changes, in turn, are associated with peripheral hormone levels which are comparatively regular and easily measured. Their measurement may be useful both in predicting behavior and in accounting for atypical menstrual-related behavior.

The role of hyperdipsia in aggression following septal lesions in rats.

Lesions of the septum in animal subjects are known to produce an increase in aggressiveness and an increase in water intake. A series of experiments was carried out to examine the possibility that aggression was secondary to hyperdipsia. When rats with septal lesions were restricted to preoperative levels of water intake, aggression scores declined significantly. When animals without lesions were preloaded, with either water or saline, aggression increased. Neither decreased shock threshold nor increased cell hydration provided a full explanation for the results. It is suggested that the aversive nature of the stomach turgescence caused by increased water intake may be an additional mediating factor in septal aggression.

Psychiatric consultation in an HMO: a model for education in primary care.

The authors describe a program based on a biopsychosocial model of illness, which uses a liaison-consultation approach in an outpatient setting. It is directed toward integrating psychiatric education and services with primary care in a health maintenance organization. This program can serve as a useful model for studying the validity and effectiveness of integrating psychiatric concepts with primary health care.

The size-color illusion.

Slides were made from Munsell color chips in three sizes, four hues, and two chromas; all had the same intensity. A direct-comparisons, forced-choice procedure was used with 100 male and female volunteers from psychology courses. When pairs of slides had the same size and chroma, the order of decreasing apparent size was red-purple, yellow-red, purple-blue, and green. At chroma/8, all comparisons were significant except yellow-red over purple-blue. At chroma/4, the same order was found, but the effect was not pronounced. When pairs were made up of identical hues but different chromas, the square with chroma/4 (less saturation) appeared significantly larger.
