This study utilized data from the Avon Longitudinal Study of Parents and Children (N = 14,860) to examine whether early-life family income (age 0-5) predicted long-term academic achievement (age 16-18) and to investigate the role of executive function (EF) assessed multiple times across age 7-11 in explaining this association. Task-based EF was a…

This study examined whether changes in children's self-reported Big Five dimensions are represented by (developmental) personality types, using a cohort-sequential design with three measurement occasions across 5 years (four cohorts, 9-12 years at T1; N = 523). Correlates of, and gender differences in, type membership were examined. Latent…

Eighty-eight children, ranging in age from 2 years 8 months to 4 years 5 months, participated. Measures…

This study examined early observed parenting and child-care experiences in relation to functioning of the hypothalamic-pituitary-adrenocortical axis over the long term. Consistent with the attenuation hypothesis, individuals (n = 863) who experienced: (a) higher levels of maternal insensitivity and (b) more time in child-care centers in the first…
