A s t a f f development model to encourage the use of microcomputers in science teaching in rural schools.

Play is a conspicuous behavior in primates, yet there are few detailed species-specific accounts of primate play. This article presents the results of a 1-year study of play in red colobus monkeys (Procolobus rufomitratus). Descriptions of play frequencies and types of play are provided from infancy through adulthood. Age and sex comparisons are discussed in light of other research and hypotheses that may explain these observations.
