Rational snacking: Young children's decision-making on the marshmallow task is moderated by beliefs about environmental reliability
Kidd, Palmeri and Aslin, Cognition 126(1), 2013, 109-114. Twenty-eight children aged 3.5 to 5.8 years were split into two groups of 14. A researcher either kept or broke a promise about art supplies before the marshmallow task. Mean wait was about 722 seconds in the reliable group and about 182 seconds in the unreliable group; 9 of 14 reliable-group children and 1 of 14 unreliable-group children waited the full 15 minutes. Age and gender did not predict waiting.
