Preschool teachers' perceptions about relationships with students (teacher-child relationships [TCRs]) predict children's subsequent social competence (SC) and academic progress. Why this is so remains unclear. Do TCRs shape children's development, or do child attributes influence both TCRs and subsequent development? Relations between TCRs and…

Guided by family risk and allostasis theoretical frameworks, the present study utilized a prospective longitudinal design to examine associations among family risk experiences, basal cortisol patterns, and cognitive functioning in children. The sample included 201 low-income children living within a midsize city in the Northeastern United States.…

This study examined longitudinal trajectories of parental involvement across middle and high school, and how these trajectories related to adolescents' academic, behavioral, and emotional adjustment. In addition, ethnic and socioeconomic status differences in longitudinal associations and the potential moderating role of parental warmth were…

Retrospective studies indicate 2 major classes of autism spectrum disorder (ASD) onset: early and later, after a period of relatively healthy development. This prospective, longitudinal study examined social, language, and motor trajectories in 235 children with and without a sibling with autism, ages 6-36 months. Children were grouped as: ASD…

A critique of research examining whether early experiences with primary caregivers are reflected in adaptation is that relevant longitudinal studies have generally not employed genetically informed research designs capable of unconfounding shared genes and environments. Using the twin subsample (N = 485 pairs) of the Early Childhood Longitudinal…

The association among mothers', fathers', and infants' risk and cognitive and social behaviors at 24 months was examined using structual equation modeling and data on 4,200 on toddlers and their parents from the Early Childhood Longitudinal Study, Birth Cohort. There were 3 main findings. First, for cognitive outcomes, maternal risk was directly…

Examined fetal heart rate and movement in 31 healthy fetuses from 20 weeks through birth and at age 6 months. Found that more active fetuses were more difficult, unpredictable, unadaptable, and active as infants that were less active fetuses, and that higher fetal heart rate was associated with lower emotional tone, activity level, and…

Examined relationship of emotion regulation and emotionality to social functioning in 77 children followed from age 4 to age 10. Found that high-quality social functioning was predicted by high emotion regulation and low nonconstructive coping, negative emotionality, and emotional intensity. Measures of regulation and emotionality frequently…

Investigated genetic change and continuity within the domains of temperament, emotion, and cognition and language for 200 pairs of twins assessed at 14 and 20 months of age. Correlations of measures at the two ages indicated that individual differences in the second year of life showed greater change than continuity on most measures. (MDM)

Data were examined to determine (1) the stability of negative emotional characteristics from early life through adolescence; (2) the degree of relation between these emotional characteristics and adjustment in childhood and adolescence; and (3) the degree to which the characteristics differentially predict multiple adjustment dimensions in…

Examined relations between maternal control and evaluative feedback during the second year of life and children's mastery motivation and expressions of self-evaluative affect a year later. Found that negative maternal evaluations at 2 years related to children's later shame, especially when linked to children's actions or products. Positive…

Examined the relations of teachers' and parents' reports of children's shyness at ages 6-8, 8-10, and 10-12 years to dispositional regulation, emotionality, and coping. The overall pattern of findings was partially consistent with the conclusion that parent-rated shyness reflected primarily social wariness with unfamiliar people, whereas…

Observed 193 children at 4.5 years who had been classified at 4 months as high or low reactive to stimulation for signs of inhibited or uninhibited behavior. Children classified as high reactive were less spontaneous and less sociable than low-reactive children, but only a small proportion maintained a consistently inhibited or uninhibited…

Examined continuity, stability, and change in behaviors reflecting infant reactivity and regulation. Subjects were 100 infants of 5 and 10 months old. Found that infant behaviors during frustrating situations showed both change and continuity, but the relationship between reactivity and regulation changed in that both factors became more…

Examined multiple measures of 82 young children's emotionality, regulation, and social functioning over a 2-year period, finding that social functioning was predicted by low negative emotionality and high levels of regulation. Also found that vagal tone was positively related to competent social functioning and emotionality/regulation for boys,…
