In this experiment, one digit arithmetical problems followed by a masking sound were given auditorily from a computer. Three types of calculation tasks; addition tasks, multiplication tasks, and kuku tasks, were tested under two conditions that varied depending on the position of the masked sound in a given formula. For example, when a left side of a calculating formula consisted of number 6 and 7, the addition task was conducted as “6 + X (masking sound) = 13 (roku, tasu, X, wa, juusan)”, or as “X + 7 = 13”, and the multiplication task was presented as “6 × X = 42 (roku, kakeru, X, wa, yonjuuni)”, or “X × 7 = 42”, while the kuku task was presented as “roku, X, shijuuni”, or as “X, shichi, shijuuni”. When each stimulus was presented, each of the participants of 10 men and 10 women was required to respond by answering with what was missing. The results revealed that they answered faster in the kuku tasks than in addition tasks. The results indicate the possibility that calculation by kuku was mostly executed through a process similar to a playback of verbal memory stored as linguistic representation, and when we could ascertain the kuku tasks, the quantitative representation of numbers almost do not come to the surface. Thus, Japanese adults answered faster in the kuku tasks than in the addition tasks.

現在、発達障害児童の割合は多くなってきており、その理解と対応は急務となってきている。こういった割合の高さからも教育的なニーズが高まっており、その機序の解明は重要である。これまで自閉症に関して認知科学の視点からコネクショニスト・モデルが提唱されており、特に線形分離できない課題が自閉症者で難しいことが指摘されている。しかし、論理演算を組み込んだ行動実験はこれまでないためおもちゃに論理演算を組み込んだ実験を行い、自閉症児と定型発達児で比べてみる研究を行った。
