Research in the field of positive psychology has revealed many advantages of positive emotions. According to the undoing hypothesis (Fredrickson & Levenson, 1998), positive affect can undo the physiological effects of negative emotion. The present study examined whether positive emotions could undo the cognitive effects of negative emotion. A categorization task was used to measure changes in cognitive processing, as measured by reaction time and accuracy, of 69 college students who were induced into a positive, negative, or neutral affective state by viewing various film clips. The results of this study did not support the extension of the undoing hypothesis to cognitive processing.
