Two roads leading to the same evaluative conditioning effect? Stimulus-response binding versus operant conditioning.

Abstract

Evaluative Conditioning (EC) refers to changes in our liking or disliking of a stimulus due to its pairing with other positive or negative stimuli. In addition to stimulus-based mechanisms, recent research has shown that action-based mechanisms can also lead to EC effects. Research, based on action control theories, has shown that pairing a positive or negative action with a neutral stimulus results in EC effects (Stimulus-Response binding). Similarly, research studies using Operant Conditioning (OC) approaches have also observed EC effects. The aim of the present study is to directly compare EC effects elicited by two different response-based approaches - S-R bindings and OC. To this end, participants were randomly assigned to an S-R binding procedure and an OC procedure. EC effects were measured in conditions and compared. Implications for EC theory are discussed.
