Biopsychosocial processes in early development: Using large-scale longitudinal studies to uncover interacting developmental mechanisms

Fri, March 24, 3:30 to 5:00pm, Salt Palace Convention Center, Floor: 3, Meeting Room 355 B

Session Type: Paper Symposium

Abstract

The many multi-faceted mechanisms that shape early socioemotional development have often been assessed as individual processes in isolation to boost power and experimental control. However, human development is embedded within the environment, such that cognitive and emotional mechanisms are always interacting with factors like parenting and the broader neighborhood to shape patterns of behavior. Addressing the complexity of development requires large-scale studies, often longitudinal, that can track change across multiple levels of analysis to discern core developmental mechanisms that shape change over time. In 2016, we presented a symposium at ISDP on the first large cross-sectional study (N=261) of infants' age-related differences from 4 to 24 months of age in both cognitive (i.e., attention bias to threat) and emotional (i.e., temperament) mechanisms thought to shape development and risk for anxiety. Here, we present a new, larger, and diverse longitudinal (N=357) dataset from the Longitudinal Attention and Temperament Study (LANTS), extending the cross-sectional work to describe how the inter-relations between our initial measures, in the context of broader developmental forces, emerge and change between 4 and 24 months of age, to shape early developmental trajectories across multiple domains. The four talks assess normative patterns of attention, the interaction between the environment and the infant, and the unexpected impact of COVID in the first two years of life.
