Predicting Positive Affect in Infancy.

Developmental science - 1 May 2026

Grossmann Tobias, Miller Halle, Allison Olivia

Abstract excerpt

Positive affect (PA) is integral to health and development, yet its early origins remain largely unexplored. In this pre-registered study (N = 78), we investigated whether infant-specific biological and social-behavioral factors predict PA in early development. Seventy-eight typically developing infants and their mothers from a longitudinal cohort contributed complete data. At 5 months, infant CD38 rs3796863...
