Abstract
Children aged 5 and 8 years and adults were tested on a temporal generalization task with a standard duration of 600 ms in a condition with or without corrective feedback. In all conditions, the participants produced orderly temporal generalization gradients, although these were flatter in the younger children, especially in the no-feedback condition. Nevertheless, the results show that the feedback increased the steepness of the generalization gradient in all age groups and in a greater extent in the younger children. Our clock-based model suggested that feedback reduces the variability of the memory representation of the standard duration but also the probability of random responses in the 5-year-olds.
Notes
Previous ANOVAs revealed neither significant main effects of gender or press button order, nor significant interactions involving these factors. Therefore, they were excluded from subsequent statistical analyses.
The ANOVA with the stimulus durations as repeated measures showed evidence of a departure from the sphericity assumption (Mauchly sphericity test, W = .27, p < .001). As required in this case, the reported probability levels have been adjusted by means of Greenhouse-Geisser corrections.
