Does promising facilitate children's delay of gratification in interdependent contexts?

Area of Science:

• Developmental Psychology
• Behavioral Economics
• Social Psychology

Background:

• Cooperation often requires delaying gratification for future rewards.
• Understanding factors that promote self-control in children is crucial for social development.

Purpose of the Study:

• To investigate if a promise to wait influences children's self-control in a cooperative task.
• To examine the impact of explicit promises versus social risk on delaying gratification.

Main Methods:

• An online cooperative marshmallow test with 5- to 6-year-old children (n=66).
• Children interacted via video call with a confederate child.
• Two conditions: a promise to wait vs. a social risk of the confederate eating their treat.

Main Results:

• Children in the promise condition waited significantly longer to eat their treat compared to the social risk condition.
• Younger children demonstrated improved delay of gratification in the promise condition.
• Results held across the full and a reduced dataset (n=48) excluding interruptions.

Conclusions:

• Explicit promises can enhance children's motivation to delay gratification in interdependent tasks.
• Even one-sided communication, like a promise, can support cooperative behavior and self-control.
• Findings highlight the role of social cues in developing children's self-regulation skills.
