Average (triangles) and individual (dots) looking times to trials consistent with the first trial type (light gray) compared with inconsistent trials (dark gray) in experiment 2. (Left) Looking times in the nap group. (Right) Looking times in the wakefulness group. All infants in experiment 2 were 18 mo of age. An ANOVA revealed a significant delay type × trial type interaction, with infants in the nap group looking longer to trials consistent with the first test trial type, while wakefulness infants showed no difference in looking between trial types.
