Studies of whether an infant's concept of object permanence develops at different rates for different objects have generally confounded the familiarity and motivational properties of test objects. To separate these factors, infants' search behavior for an unfamiliar control object was compared with that for (a) a familiar object and (b) an "attached" object reported to comfort the infant in times of stress. As compared to unfamiliar objects, no increase in search behavior was found for familiar objects. Whether or not it significantly increased for attached objects depended on which of 2 examiners administered the object-permanence test. It is concluded that the results are best explained by motivational factors and that this has important implications for object-permanence testing.
