Early Quantitative Characterization of Reciprocal Social Behavior (ERSB)
The ERSB study was focused on the development, validation, and standardisation of quantitative methods to measure core components of variation in the social development of young children. Participants were parent-child dyads including toddler-aged twins born from 2011 to 2013, recruited from birth registries in Missouri and California, the United States of America. Around 300 participants in Missouri and 400 participants in California completed a baseline assessment beginning in 2013. Participants were assessed when children were 18, 24, 36, and 48 months of age.
