Goal-Based Binding of Irrelevant Stimulus Features for Action Slips

Abstract

Binding between representations of stimuli and actions and later retrieval of these compounds provide efficient shortcuts in action control. Recent observations indicate that these mechanisms are not only effective when action episodes go as planned, but they also seem to be at play when actions go awry. Moreover, the human cognitive system even corrects traces of error commission on the fly because it binds the intended but not actually executed response to concurrent task-relevant stimuli, thus enabling retrieval of a correct, but not actually executed response when encountering the stimulus again. However, a plausible alternative interpretation of this finding is that error commission triggers selective strengthening of the instructed stimulus-response mapping instead, thus promoting its efficient application in the future. The experiment presented here makes an unequivocal case for episodic binding and retrieval in erroneous action episodes by showing binding between task-irrelevant stimuli and correct responses.
