Feature binding and episodic retrieval in blindness for congruent stimuli: evidence from analyses of sequential congruency.

Targets are identified more poorly when presented during a congruent cued response than during an incongruent cued response (blindness effect). The authors investigated sequential trial dependencies in the blindness effect. The results show that the size of the blindness effect depends both on the previous cued response-target congruency relationship and on repetition of events from the preceding trial. This finding suggests that cued responses and targets become linked together in a single episodic trace; repeating one of these events from the preceding trial activates the other. Depending on whether the activated representation matches or conflicts with events on the current trial, target identification performance is either facilitated or impaired. Implications for action planning and feature binding are discussed.
