Following the self-regulation, sleep, and temperament measures used in our current study of toddler sleep, we will follow children into pre-K. New collections of data will include:

• Measures of pre-K teachers’ perceptions of children’s temperament
• Behavior
• Academic progress
• Parents’ perceptions of children’s temperament and sleep characteristics
• Children’s performance in self-regulation tasks
• Observations of pre-K classroom processes and children’s engagement in the pre-K classroom

The follow-up project seeks to investigate how children’s self-regulation development and sleep can predict academic and social adjustment in pre-kindergarten (pre-K); and how positive pre-K classroom experiences can benefit children’s academic and social adjustment.
