Provides overview of attachment theory as parented by John Bowlby in "Attachment and Loss". Uses two major concepts from this work to interpret refinements and elaborations of attachment theory attibuted to Mary Ainsworth. Considers how recent insights into development of socioemotional understanding and development of event…

Examines the meaning of reaction time (RT) and the possibility that it may predict other cognitive and motor skills in the first year of life. Considers two competing models that specify the information-processing components underlying RT performance. Describes the neural data needed to definitively choose between the models and considers…

A reanalysis of recent clinical research suggests that three different neural processes or brain mechanisms may underlie the regulation of emotion: (1) contralateral disinhibition of cortical centers; (2) ipsilateral disinhibition of subcortical centers; and (3) excitation of specific subcortical or neocortical centers. (MDM)

In 2 studies, subjects between 7 and 16 years of age indicated predictions for the water level in a tilted container or the position of a plumb line. Found that sex differences were evident at all ages; task performance improved with age according to a discrete stage process; and task performance was determined by field effects and rule strategy.…

This essay asserts that clinical conceptualizations of emotion that stress its disruptive influences and functional models of emotion that emphasize its adaptive aspects can be integrated into a developmental psychopathology framework. Under certain conditions, emotion regulation may develop dysregulatory aspects that can become a characteristic…

Speculates on underlying processes for the reaction time variance and age differences in anticipation latency using the Visual Expectation Paradigm. Discusses the dichotomization of reactive and anticipatory behavior, limitations of longitudinal designs, drawbacks in using standard procedures and materials, and inferences that can be made…

This essay discusses the evaluation of the relationship between the nervous system and emotion regulation, introducing vagal tone as a measurable organismic variable that contributes to individual and developmental differences in the expression and regulation of emotion. (MDM)

Analyzed 1.5- and 2.5-year-olds' problem solving and learning. Found that changes in toddlers' strategies could be assessed reliably on a trial-by-trial basis, that changes followed the basic form predicted by the overlapping waves model, and that analyses could reveal information about the qualitative and quantitative aspects of their learning.…

This essay argues that the activity of the hypothalamic-pituitary-adrenocortical (HPA) system does not appear to be related to emotion regulation processes in children, although individual differences in emotion processes related to negative emotion temperaments appear to be associated with individual differences in HPA reactivity among normally…

This essay examines the development of individual differences in emotion regulation and the role that specific styles of emotion regulation and dysregulation play in affecting young children's interactive behavior with peers. It advances a general developmental pathway that conceptualizes individual variations in terms of both infant traits and…

Identifies contributions of Liben and Bigler's studies to gender development related to measuring self and other sex typing, developing a theoretical account of the self-other relation, and incorporating individual differences. Raises questions about measures used and interpretations of the findings. Suggests issues for future research:…
