Development, Attention, and Inhibition Study

This study is looking at how young children's early experiences with waiting affect their ability to delay gratification (waiting for a desired reward) and how this relates to their development later in life. Researchers want to understand if waiting experiences predict how well children can delay gratification in different situations, and if social rules, effort, or choices impact these connections. Children will complete tasks involving delaying a sweet or a gift, play "Simon says"-like games, and answer questions about school readiness and social rules. Parents will also answer questions about their child's behavior and experiences with waiting. This study is for typically developing children aged 4 to 7 years old. The study aims to enroll 200 children.

Study design
This interventional study plans to enroll 200 children aged 4 to 7. Children will be randomly assigned to one of two groups for a delay of gratification task.
What's involved
You and your child will participate in two sessions initially, and then a third session one year later. These sessions involve your child completing various tasks and games, while parents complete questionnaires.
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed for one year after the initial intervention, with a third session repeating measurements from the first two sessions.
