Evaluative conditioning may incur attentional costs.
Evaluative conditioning (EC) refers to changes in the liking of an affectively neutral stimulus (conditioned stimulus, or CS) after pairing this stimulus with an affect-laden stimulus (unconditioned stimulus, or US). Several authors proposed that EC incurs little or no attentional cost. Using a rigorous design, we provide evidence that a reduction in attentional resources may have a negative impact on EC. Additional analyses also revealed that participants correctly encoded fewer CS-US pairings when their attentional resources were depleted. Replicating Pleyers, Corneille, Luminet, and Yzerbyt's (2007) findings, EC was also obtained only for CSs that could be correctly linked to their associated US in the context of an identification task. This research clarifies the role of higher order processes in EC and has significant practical implications.
