Developmental Implications of Early Childhood Sleep

In this study, we are investigating whether naturally-occurring sleep patterns affect children's cognitive development and temperamental self-regulation.

Toddler participants will be tested three times over the course of one year, at ages 30 months (2.5 years), 36 months (3 years), and 42 months (3.5 years).; Participation at each age involves two home visits and a visit to the EDL laboratory, each lasting approximately 1-2 hours. Parents will be asked to fill out questionnaires about their toddlers’ sleep habits, temperament, behaviors, routines, social supports, and recent family events.  Toddlers will also be given a watch-like device to wear over the course of two weeks that measures their motor activity.
