Evaluative Conditioning (EC) refers to changes in attitude towards a conditioned stimulus (CS) due to its pairing with a positive or negative unconditioned stimulus (US). In this symposium, we discuss various context-related and cognitive factors that may influence EC effects and shape the resulting conditioned attitudes. The first talk will explore whether letting participants rate a CS both before and after conditioning - rather than only afterward - impacts EC effects. The second talk centers around valence asymmetries resulting from differences in the frequency of positive and negative USs during EC. Whereas prior research has focused on valence asymmetries for individual stimuli, this talk extends the analysis to groups, demonstrating that rare group members can disproportionately affect overall group evaluations. Focusing on instances of EC with multiple, simultaneously appearing USs, the third talk presents evidence that adding weakly positive (negative) USs to a highly positive (negative) US diminishes EC effects. The fourth talk investigates the role of language for the conditioning process, testing whether a native vs. a secondary language context during EC leads to different outcomes. The last talk examines autonomous sampling during EC, asking whether merely instructing participants to sample certain stimuli more frequently is sufficient to achieve the effect that autonomous sampling has on conditioned attitudes. In summary, these talks offer valuable insights into how contextual and cognitive processes shape EC effects, enhancing our understanding of EC and highlighting promising directions for future research.

Research on Evaluative Conditioning (EC), that is, changing attitudes towards a Conditioned Stimulus (CS) by pairing it with a positive or negative Unconditioned Stimulus (US), has recently begun investigating stimulus-rich contexts with multiple USs appearing simultaneously. Evidence suggests that in these situations, conditioned attitudes follow the average valence of the simultaneously paired USs. One crucial yet unexplored consequence of this averaging pattern is the occurrence of a dilution effect: adding less positive (negative) USs to a situation with a highly positive (negative) US should diminish attitudes towards the paired CS, despite the less positive (negative) USs on their own being able to influence CS attitudes. To investigate this consequence, we conducted three experiments (N = 1100) in which CSs appeared with different combinations of USs with varying positive (negative) valence levels. Overall, the results confirm the averaging pattern observed in previous studies, which indeed led to a dilution effect in our EC paradigm: CSs simultaneously paired with a highly positive (negative) US and less positive (negative) USs were rated less positive (negative) compared to CSs that exclusively appeared with a highly positive US. The results suggest that when changing attitudes via EC in stimulus-rich contexts, US valence is more important than US quantity.
