The International Affective Picture System (IAPS) is widely used in studies of emotion and has been $\backslash$ncharacterized primarily along the dimensions of valence, arousal, and dominance. Even though $\backslash$nresearch has shown that the IAPS is useful in the study of discrete emotions, the categorical structure $\backslash$nof the IAPS has not been characterized thoroughly. The purpose of the present project was to collect $\backslash$ndescriptive emotional category data on subsets of the IAPS in an effort to identify images that elicit $\backslash$none discrete emotion more than others. These data reveal multiple emotional categories for the images $\backslash$nand indicate that this image set has great potential in the investigation of discrete emotions. This $\backslash$narticle makes these data available to researchers with such interests.
