Discusses the conflict between situational influences and stable individual differences in attachment behavior and attempts to resolve this conflict by examining the functions, outcomes, and context sensitivity of attachment behavior and the underlying behavioral control systems that organize it.

Reviews Greenough, Black, and Wallace's (1987) conceptual framework for understanding the effects of early experience and sensitive periods on development, and illustrates the applicability of their model with recent data on the consequences for animals and human infants of the acquistion of self-produced locomotion.

The role of experience in the developing brain is considered. A categorization scheme based upon the type of information stored and the brain mechanisms involved in storing the information is proposed. Experience-expectant and experience-dependent information storage are differentiated. (BN)

The developmental pattern of concurrent synaptogenesis in rhesus monkeys is consistent with a straightforward model of relations between brain and cognitive development. Concurrent synaptogenesis is hypothesized to lay the primary cortical foundation for a series of developmental levels in middle infancy that have been empirically documented in…

Points out the need for and proposes a developmental model of self-understanding (the cognitive basis for self-conception), analyzing the self as a cognitive concept and giving a chronological account of developmental trends in self-understanding. (RH)

Presents French-speaking researchers' contribution to differential developmental psychology. Traces methodological and theoretical transformations necessary for understanding individual differences within a general theory of cognitive development. Provides overview of pluralistic and multidimensional model of cognitive functioning/development…

Examined predictors and sequelae of homesickness in 293 boys, ages 8 to 16 years, who spent two weeks at an overnight camp. Found that the "homesick disposition" and little prior separation together accounted for 69% of the variance in self-reported homesickness. Interpersonal attitudes and perceived control predicted 70% of the variance…
