Evaluated respiratory sinus arrhythmia (RSA) and heart period in 5-month-olds during interaction challenges. Found that during object-mediated challenge, RSA increases were uniquely related to positive engagement. During person-mediated challenge, subjects showed more complex integration of autonomic and behavioral responses such that only infants…

This comprehensive study of mutual responsiveness examined 102 mothers and 102 fathers interacting with their children at 7 and 15 months. Responsiveness was studied from developmental and individual differences perspectives, and assessed using macroscopic ratings and microscopic event coding. The latter captured parents' reactions to children's…

Although the identity formation model is widely used to assess adolescent ethnic identity development, the model propositions have rarely been tested. The existence of the identity statuses (diffuse, foreclosed, moratorium, achieved), the proposed developmental trajectories, and whether youth in the achieved status report higher levels of…

Eight reflective and eight impulsive preschool children were tested in a forced-choice recognition memory task. Reflective children made more correct recognition choices than did impulsive children under all experimental conditions. (ST)

Investigated birth-order differences in children's early vocabulary development. Compared the composition and age of acquisition of the first 50 and 100 words of 9 firstborns and their younger siblings, using a longitudinal maternal diary methodology.

Highlights three longitudinal studies examining the hypothesis that attachment security during infancy influences individual differences and adult representations of attachment. Notes that attachment security was significantly stable in two studies, with discontinuity in all three studies related to negative life events and circumstances.…

Assessed attachment security in 60 white middle-class infants at 12 months and conducted Adult Attachment Interview 20 years later. Found that 72 percent of infants received same attachment classification in early adulthood. Forty-four percent of infants whose mothers reported negative life events changed attachment classifications by adulthood,…

Examined development of child and adolescent self-concept in two overlapping age cohorts as a function of the self-concept domain, social/developmental/educational transitions, and gender. Structural equation modeling addressed questions about stability of individual differences over time. Multilevel modeling addressed questions about mean-level…
