Mere repeated exposure and experimental stress as determiners of stimulus evaluations

From Berlyne's theorizing concerning the determinants of hedonic value of a stimulus it was hypothesized that importance of evaluative judgments and frequency of exposure would interact in determining the favorability of affective ratings. This prediction was confirmed by the data. Increasing the importance of the rating task decreased the favorability of the ratings of low-frequency stimuli but enhanced the ratings of high-frequency stimuli.The experiments reported here were conducted at the Laboratorium voor Experimentele Sociale Psychologie at Leuven. This article is based on the author's doctoral dissertation, which was supervised by J. M. Nuttin, Jr. I would also like to thank J. M. Nuttin, Jr., E. Van Avermaet, and J. Hatcher for their helpful comments on a previous draft.
