title: When irrelevance matters: Stimulus-response binding in decision making under uncertainty.
abstract: According to distractor-based response retrieval (Frings, Rothermund, & Wentura, 2007), irrelevant information will be integrated with the response to the relevant stimuli and further, the immediate repetition of irrelevant information can retrieve the previously executed response thereby influencing responding to the current target (leading either to benefits or costs if the retrieved response is compatible or incompatible, respectively, to the currently demanded response). We analyzed whether this effect also holds for decisions rather than simple motoric reactions. The hypothesis was tested in 4 experiments in which participants had to decide as fast as possible which disease an imagined patient suffered from. The decisions were based on 2 cues; 1 did not give any hint for a disease (the irrelevant cue), whereas the other did (the relevant cue). We found a significant influence of repeating the irrelevant cue on decision behavior. That is, participants tended to repeat their decision if the irrelevant cue was repeated in the following decision situation. Thus, stimulus-response binding which typically is discussed in basic processes of perception and action has also implications for arguably more deliberative cognitive processes in decision making under uncertainty.
