Abstract
Cambridge, Mass., Perseus, 2002. $26.0-7382-0278-9 Students who read about Harry Harlow in textbooks of psychology or animal behavior are usually presented with two impressions: appealing pictures of young rhesus monkeys clinging tightly to cloth- or wire-covered mother surrogates equipped with small nursing bottles for feeding, and the almost obligatory, sanctimonious comments about the alleged cruelty of Harlow's monkey experiments (Figure ). The surrogate studies were quickly followed by others on the effects of social isolation on behavioral development and maternal behavior, including demonstrations that the depression sometimes observed in human children who had been separated from their mothers could be reproduced in young rhesus monkeys.
