Preferences in Recall of Pleasant and Unpleasant Images

摘要

The role of emotional state on memory has been well established. How emotion provoking stimuli influence the cognitive processes is, however, not well understood. Our broad objective was to see the impact of emotion provoking visual stimulus on memory. Sixty images were generated using Indian version of the Geneva Affective Picture Database (GAPED). Four categories of images (child, adult, animal and landscape) were either pleasant or unpleasant in nature. These images were shown to thirty participants following a repeated measure design. Immediate free recall of the images was recorded to see the effect of type of image on recall. Bayesian inference was used to analyze the data. Results show evidence for effect of type of image on recall by 120:1 against the null. The model of image category was also preferred to the null by 35:1.
