At the crossroads: Attention, contingency awareness, and evaluative conditioning

Evaluative conditioning (EC) refers to changes in the evaluation of a conditioned stimulus (CS) due to its repeated pairing with an unconditioned stimulus (US). One of the most debated topics in EC research is whether or not EC is dependent on contingency awareness. In this study, we go beyond this debate by examining whether contingency awareness mediates the impact of attentional resources and goal-directed attention on EC. Attentional resources were manipulated by presenting CSs and USs either within the same modality or in different modalities. Goal-directed attention was manipulated by asking participants to respond to the CSs or to the USs. Results indicate that the effect of goal-directed attention on EC is mediated by contingency awareness, whereas the effect of attentional resources on EC is not.

► Awareness mediates the impact of goal-directed attention on evaluative conditioning.
► Awareness does not mediate the effect of attentional resources on evaluative conditioning.
► Attention towards the CS determines the extent to which CS–US contingencies are processed.
