Two independent cohorts (N = 155, N = 126) of infants at high and low risk for autism spectrum disorder (ASD) were followed prospectively between 6 and 36 months of age, when n = 46 were diagnosed with ASD. Gaze to adult faces was coded--during a developmental assessment (Cohort 1) or a play interaction (Cohort 2). Across both cohorts, most…

Individuals with sex chromosome trisomies (SCTs) have an increased risk of language delays and impairments. However, there are only a few data relative to their language development in early childhood. The present study aimed to investigate the preverbal skills shown by a group of 8-month-old children with SCTs to assess the presence of a possible…

We examined the associations between language skills and concern and disregard for others in young children assessed longitudinally at ages 14, 20, 24, and 36 months, testing the hypothesis that language skills have a specific role (distinct from that of general cognitive ability) in the development of concern and disregard for others. We found…

This study examined identity development in a 5-wave study of 923 early-to-middle and 390 middle-to-late adolescents thereby covering the ages of 12-20. Systematic evidence for identity progression was found: The number of diffusions, moratoriums, and searching moratoriums (a newly obtained status) decreased, whereas the representation of the…

Identifying early precursors of body mass index (BMI) and sports participation represents an important concern from a public health perspective and can inform the development of preventive interventions. This article examines whether kindergarten child self-regulation, as measured by classroom engagement and behavioral regulation, predicts healthy…

The Taiwan Birth Cohort Study (TBCS) is the first nationwide birth cohort database in Asia designed to establish national norms of children's development. Several challenges during database development and data analysis were identified. Challenges include sampling methods, instrument development and statistical approach to missing data. The…

The purpose of this paper is to provide a comprehensive review of the empirical findings on the stability of attachment from infancy through adulthood. More specifically, the paper discusses the longitudinal research concerning the continuity of attachment from infancy to adulthood as well as those studies that have assessed stability within a…

Developmental and life course studies of young adult identities have focused on 2 dimensions: subjective age and psychosocial maturity. This study examines the developmental synchrony of these 2 processes. In a longitudinal sample of young adults from Add Health (ages 18-22), a person-centered analysis of indicators of these dimensions identified…

Developmental needs should be assessed in early infancy and followed longitudinally to improve identification, prevention and intervention efforts.The objective was to examine the relationship between competencies and areas of need in toddlers' development, and to describe the properties and utility of the Brief Infant Toddler Social-Emotional…

The goal of this longitudinal study is to examine the relationships between early child factors (i.e., age at identification, enrollment in early intervention, oral language skills) and school readiness skills (i.e., conceptual knowledge) in a group of young children with hearing loss (HL). Standardized language, cognition, and conceptual…

There is a long-standing lack of integration between the fields of child development and health and health services research. In this brief, we review scientific evidence from all these literatures as they relate to early school readiness, focusing on results from large longitudinal studies. The review does not cover the substantial literature in…
