It was confirmed using the reproduction method and using both children of 8 to 13 years and adults as subjects that the anti-kappa effect could occur even for static stimuli under the specific condition where subjects were induced to form the set to use velocity rather than spatial separation as the cue for the time estimation. The present finding concerning the effects of the spatial separation of successively presented static stimuli on the time estimation was in line with the hypothesis of “cue-selection sets” which was drawn from the results of the first author's previous studies on a moving stimulus. But the developmental tendency of the anti-kappa effect still needs to be examined further.
