The interplay of multiple unconditioned stimuli in evaluative conditioning: A weighted averaging framework for attitude formation via stimulus co-occurrences.

Evaluative conditioning (EC) is a key effect in attitude formation, leading to changes in the liking of neutral attitude objects due to their pairing with positive or negative stimuli. Despite EC's significance, current theories and most empirical findings are limited to stimulus pairings with a single affective stimulus at a time. In contrast, social environments often involve more complex combinations of affective stimuli.
