A further investigation of the filled-duration illusion with a comparison between children and adults.
This study investigated the filled duration illusion in children in comparison to adults, using a temporal bisection task with two ranges of anchor durations (1 vs. 4s and 2 vs. 8s). The results revealed a marked filled duration effect when filled and empty durations were presented in the same session (within-subjects condition), with the filled durations being judged to be longer than the empty durations in all age groups. However, the magnitude of this effect appeared to be larger in the children than in the adults. Furthermore, the filled duration effect decreased with the longest duration stimuli, and apparent reversals of this effect were observed with the empty durations being judged longer. In the between-subjects experiment, the filled duration effect disappeared in all age groups. However, in the children, the variability in the temporal judgment appeared to be greater for the empty than for the filled durations, thus indicating a lower sensitivity to empty durations.
