Abstract

<p>本研究では自閉スペクトラム症児を対象に、選択後に提示する強化子の量や強化子の違いが選択に与える影響を検討した。実験では2 つの選択肢を提示し、一方は相対的に強化子の量が多く、もう一方は相対的に強化子の量が少ない選択肢であった。強化子を提示する量を操作し、両選択肢に強化子を提示する条件と一方の選択肢には強化子が提示しない条件の2 つの条件を設定した。また実験ではキャラクターの画像とお菓子を強化子として用いた。実験の結果、両選択肢に強化子が提示される条件よりも、一方の選択肢には強化子が提示されない条件において、量の多い強化子が得られる選択肢の選択率が高い傾向が見られた。また強化子の種類によっても量の多い強化子が得られる選択肢の選択率に違いが見られた。提示される選択肢の量の違いが明確であることが選択に影響し、強化子の種類は強化子の量の弁別に影響する可能性が示唆された。</p>

<p>In this study, we examined the effects of the reinforcer amount presented after choice and the impact of reinforcers on choice in children with autism spectrum disorder. Two alternatives were presented in the experiment: One with a relatively large number and the other with a relatively small number of reinforcers. By manipulating reinforcer amount presented, two conditions were set: One where the reinforcers were presented for both alternatives and the other where they were not presented for one alternative. Character image and food were used as reinforcers. The results revealed the rate of choice for the alternative with many reinforcers was higher in the condition where the reinforcers were not presented in one alternative than when the reinforcers were presented in both options. In addition, there was a difference in the rate of choice of options from which many reinforcers were obtained depending on the type of reinforcer. In conclusion, it was suggested that when the difference in the reinforcer amount of choices presented was clear, which influenced the choice was influenced. Furthermore, the type of reinforcers influenced the choice of reinforcer amount.</p>
