NCT06605001

Brief Summary

The goal of this clinical trial is to test the associations of young children's early life experiences with delaying behaviors and links with later life outcomes. The main questions it aims to answer are:

  • Do experiences with waiting in early childhood predict delaying behavior in context-specific ways?
  • Are links between delaying behavior and life outcomes impacted by social conventions, effort and choices around delaying, or other behaviors? Participants will:
  • Complete two delaying tasks with either a sweet or wrapped gift
  • Complete three "Simon says"-like games that measure inhibition, cognitive flexibility and proactive control
  • Answer a set of questions about academic readiness
  • Answer a set of questions about social conventions
  • Complete a waiting game on the computer while a camera records eye movements
  • Parents will answer questions about their child's behaviors and experiences at home
  • Participants will return after 1 year to repeat a subset of these measures
