Evaluative conditioning refers to a change in one's like or dislike of a stimulus when the stimulus is paired with other positive or negative stimuli. Evaluative conditioning is thought to be a major cause of the development of the like or dislike of innately neutral things including odors. The current study examined whether a group exposed to an explicit relationship by picture (unconditioned stimulus; US) - odor (conditioned stimulus; CS) memory tasks would undergo more evaluative conditioning than a group exposed to no explicit relationship. In Experiment 1, the US-CS pairing was repeated five times because past research revealed robust evaluative conditioning occurred after five repetitions. In Experiment 2, the US-CS pairing was repeated only once. In both experiments, evaluative conditioning was observed. The results showed that repetition of the pairings slightly strengthened the effects of evaluative conditioning.
