Repetition blindness for faces: A comparison of face identity, expression, and gender judgments
Repetition blindness (RB) refers to the impairment in reporting two identical targets within a rapid serial visual presentation stream. While numerous studies have demonstrated RB for words and picture of objects, very few studies have examined RB for faces. This study extended this research by examining RB when the two faces were complete repeats (same emotion and identity), identity repeats (same individual, different emotion), and emotion repeats (different individual, same emotion) for identity, gender, and expression judgment tasks. Complete RB and identity RB effects were evident for all three judgment tasks. Emotion RB was only evident for the expression and gender judgments. Complete RB effects were larger than emotion or identity RB effects across all judgment tasks. For the expression judgments, there was more emotion than identity RB. The identity RB effect was larger than the emotion RB effect for the gender judgments. Cross task comparisons revealed larger complete RB effects for the expression and gender judgments than the identity decisions. There was a larger emotion RB effect for the expression than gender judgments and the identity RB effect was larger for the gender than for the identity and expression judgments. These results indicate that while faces are subject to RB, this is affected by the type of repeated information and relevance of the facial characteristic to the judgment decision. This study provides further support for the operation of separate processing mechanisms for face gender, emotion, and identity information within models of face recognition.
