Peeking behavior
Overall, due to the highly tempting nature of the game, 73% (122/168) of children peeked at the toy
in the experimenter’s absence, including 70% (40/57) of 3-year-olds, 80% (41/51) of 4-year-olds, and
68% (41/60) of 5-year-olds. A logistic regression was performed with age and gender as the predictors
and peeking behavior as the predicted variable (where 1 = peeked and 0 = did not peek). No significant
effect of age or gender was found.
