五十音の順序判断にあらわれる心的機制の検討

抄録

To examine the underlying processes in the order judgments of Japanese syllabary, two experiments were conducted. In both experiments, subjects indicated by a binary motor response whether a pair of syllables were in proper order or not. In Experiment I syllables were paired in each row, and in Experiment II they were paired in each column of Japanese syllabary. Time to make such judgments was shorter for greater separation between two syllables (with the exception of Experiment I), and shorter for syllable pairs in proper order than for reversed order pairs. And depending on the conditions, serial position effect (SPE) showed varieties of patterns such as bowed SPE, monotonically increasing SPE, and disappearance of bowed SPE.
