The Study

Magnitude of Reward and Preference in a Delayed-Reward Situation

In simple terms

This study watched kids choose between getting a small treat now or a bigger one later, and found that bigger treats made them more likely to wait. But it didn’t change anything on purpose—it just watched what happened, so we can’t say the bigger treat made them wait.

Kids were given a choice: a small treat now, or a bigger one later. When the later treat was much bigger, they picked it more often.

Key takeaways

Summary

Based on the study abstract and findings.

  1. 1Yes — this shows that making the future reward much bigger helps kids wait, even if they're young.
  2. 2When the delayed reward was large, kids chose it more than when it was only medium-sized.
  3. 3Age didn't matter — 6-year-olds and 12-year-olds chose similarly.
