Abstract

The purpose of this study was to examine the application and acquisition of strategy in enumeration tasks. For this purpose, counting time of stimuli set size in various enumeration conditions was measured. In Experiment 1, the effect of knowledge of stimuli set size on enumeration time was examined. It was confirmed after the experiment that providing the information of stimuli set size in advance helped the participants to develop a counting strategy. In Experiment 2, the effect of the counting strategy acquired by enumeration practice without explicit verbal cueing on enumeration time was analyzed. The results showed that enumeration practice induced the acquisition of a counting strategy, which in turn produced the similar results to Experiment 1(subitizing was also observed in each session). In sum, the knowledge of set size affected on counting strategy which in turn reduced counting time for relatively larger set size of 7 to 9 items. In addition, this tendency was repeatedly observed in the experimental conditions varied by stimuli discriminability as well as amount of counting practice.
