Attention meets binding: Only attended distractors are used for the retrieval of event files

Response-irrelevant stimuli can be encoded with, and later on retrieve, a response given to a relevant stimulus, an effect that is called distractor–response binding. In three experiments using a prime–probe design, we investigated whether the allocation of attention modulates the processes contributing to distractor–response binding. Participants identified letters via keypresses while attending to one of two sets of simultaneously presented but response-irrelevant number stimuli. In different experiments, both spatial attention and feature-based attention were allocated to the response-irrelevant stimuli. The results showed that only attended response-irrelevant stimuli elicited effects of distractor–response binding. In particular, while the encoding of response-irrelevant stimuli and responses was not particularly affected by attention during prime processing, only attended response-irrelevant stimuli in the probe retrieved previous responses. Hence, we show that attention affects action regulation due to modulating the influence of stimulus–response binding on behavior.
