Mere Exposure Effect Is Sometimes Insensitive to Mood Inductions

Abstract. The mere exposure effect (MEE) is defined as repeated exposures to a stimulus enhancing affective evaluations of that stimulus (Zajonc, 1968). The three prominent explanations of the MEE are Zajonc's “neophobia” account, the uncertainty reduction account, and the perceptual fluency approach. Zajonc's “neophobia” account posits that people have an inherent low level of fear of novel objects and exposure to the objects partially extinguishes this novelty-based fear. The uncertainty reduction account asserts that people find uncertainty aversive and habituation reduces uncertainty. The fluency account postulates that people “like” representations of things with which they are fluent. In four experiments, we induced positive and negative moods before or after target exposures. In addition to assessing the MEE in each condition, we assessed the mood induction. The central hypothesis assessed in this series was that there would be an interaction between mood and the MEE. Although the three accounts of the MEE generated divergent predictions, none of the accounts were well supported by the data. Tests for mood induction demonstrated the efficacy of the induction procedures and the MEE was consistently observed, but Bayesian analysis indicated that at least in the present preparation mood had no effect on the MEE.
