Abstract:I argue that theorizing in evaluative conditioning has paid insufficient attention to distinguishing what is learned (operating principles) from how and when the learning takes place (operating conditions). In terms of its operating principles, EC effects can be established both via stimulus -stimulus (S -S) and via stimulus -evaluative response (S -R) associations. Operating conditions of EC that have received a lot of attention are the famous features of automaticity (awareness, intentionality, controllability, resource efficiency). A lot of research in our field has focused on investigating operating conditions, without specifying operating principles, which limits the interpretability of previous work, especially if conflicting findings arise. I call for putting the principles before the conditions, and to approach EC theorizing in a more piecemeal manner, from the ground up. I believe for now we should treat the operating principles and operating conditions as orthogonal, and do not assume that only certain processes can lead to certain representations. Evidently, this calls for a lot of future research, and theorizing that is more focused and precise. By specifying and testing clearly both operating principles and conditions, our theories will be (initially) smaller in scope, but likely more verifiable.
