Affective matching moderates S-R binding.

We investigated the moderating influence of affective matching on S-R binding processes in a sequential priming study in which positive and negative nouns had to be categorised as referring to a person or to an object. Irrelevant positive and negative distractor words (adjectives) were integrated with responses into S-R episodes if they had the same valence as the target (affective match condition). In this case, repeating the prime distractor in the probe led to a retrieval of the prime response, which facilitated performance for response repetition sequences but had no effect on performance when responses changed between prime and probe. However, if target and distractor had different valences (affective mismatch condition), no interaction of distractor relation and response relation occurred, indicating that distractors were less likely to be associated with responses into event files during the prime trial episode. Findings reveal that affective mismatches are detected automatically and modulate a binding of irrelevant information with responses.
