The influence of stress on distractor-response bindings.

Stimuli and responses that occur in close temporal contiguity are bound to each other and stored in short-term episodic traces or event files. A repetition of any of the features within an event file results in the retrieval of the entire event file and can influence responding. Along with task-relevant features, event files also contain task-irrelevant features, which are also bound to responses - distractor-response binding. In the present study, the distractor-response binding effect was examined under stress. Stress was induced via a Cold Pressor Test (CPT) and was manipulated between subjects. Distractor-response binding effects were measures at pre- and post-intervention. The CPT produced reliable effects on cortisol measurements and subjective ratings, however, no difference in the distractor-response binding effects between the groups was observed. Results are discussed against the background of the inconsistent results in the literature with respect to stimulus-response binding and stress.
