Evaluative conditioning (EC) impacts both valence and arousal. Affective responses condition on two dimensions, with arousal influencing memory and extinction differently than valence.
Area of Science:
- Psychology
- Cognitive Science
- Affective Science
Background:
- Evaluative conditioning (EC) modifies stimulus valence via unconditioned stimulus (US) pairing.
- Core affect involves valence and arousal, yet EC research often overlooks arousal.
- Understanding EC's dual dimensions is crucial for affective response origins.
Purpose of the Study:
- Investigate EC's impact on both valence and arousal dimensions.
- Examine the relationship between conditioned arousal, valence, and memory.
- Assess the differential extinction of conditioned valence and arousal.
Main Methods:
- Two experiments measured subjective feelings elicited by conditioned stimuli (CS).
- Paired CS with high/low arousal positive/negative USs.
- Analyzed changes in CS valence and arousal, memory recall, and extinction patterns.
Main Results:
- EC pairings altered both CS valence and arousal.
- Conditioned arousal, not valence, correlated with memory for CS-US pairings.
- Conditioned valence extinguished more readily than conditioned arousal.
- EC effects were more pronounced with high-arousal USs.
Conclusions:
- Affective responses condition along independent valence and arousal dimensions.
- Arousal plays a distinct role in EC, influencing memory and extinction.
- Future EC research should consider both valence and arousal for a comprehensive understanding.
