title: Repetition blindness for faces reflects identity coding but not emotion coding.
abstract: Repetition blindness for visually presented stimuli occurs when only one of two similar items is available to a viewer's conscious awareness. The objective of this experiment was to investigate repetition blindness for faces and to observe whether encoding of similar emotions displayed on different individuals' faces produced repetition blindness. A further aim was to assess whether such an effect could be modulated by attentional task demands (sex judgment or expression judgment). Faces were presented so that four within-participant conditions could be compared: Complete repetition, same emotion/different Identity repetition, same identity/different Emotion repetition, and No repetition trials. The data revealed repetition blindness for Complete and same identity/different Emotion repetitions, but not for same emotion/different Identity repetitions. The lack of an "emotion blindness" effect supports previous reports that emotional expressions do not necessarily lead to automatic attentional biases.
