本研究では随伴色残効が顔表情に対して生起するかどうかを調べた．実験の順応フェーズでは被験者は怒り表情の顔刺激に赤，喜び表情の顔刺激に緑で色順応する．順応前フェーズと順応後フェーズで2つの表情の顔刺激の色の見えを比較し，順応後に，顔表情に随伴した色の見えの変化，すなわち色残効の有無を調べた．その結果，順応の前後における色の見えの測定結果に有意な差はみられず，本実験の条件では顔表情に随伴する色残効は生起しないことが示された．%We examined whether contingent color aftereffect occurred for facial expression. In the adaptation phase the observer adapted to red when an angry face was presented and adapted to green when a happy face was presented. Color appearance of stimuli was compared between the pre-adaptation phase and the post-adaptation phase for both expressions to test any contingent color after effects for facial expression. The results showed that no significant difference was found in color appearance between the pre- and post-adaptation phases, in the present experimental conditions no contingent color aftereffect occurred for facial expression.
