Revisiting the Marshmallow Test: A Conceptual Replication Investigating Links Between Early Delay of Gratification and Later Outcomes

Tyler W. Watts, Greg J. Duncan, Haonan Quan · 2018 · Psychological Science

Children
About 900 children
Where
Ten places across the United States
Ages
4½ years
How
Researchers timed how long children waited for a bigger treat
What it found
At 4½, about half of the children waited the full 7 minutes. How long children waited was linked with later school results, but much less than earlier studies had suggested.
Limits
Tested only one age, so it can't show when children start being able to wait.
