Exemplification theory has wide use in news and health communication studies with test messages in text, video, and still images. The theory promises to aid in crafting influential messages in mass communication. However, the mechanics of exemplification need clarification. Most studies that use photographs manipulate contextual text rather than images. Furthermore, half of the hypotheses in 20 years of exemplification research have not been supported. To clarify the visual manipulation of emotion in exemplification, a 4 x 4 within-subjects experiment manipulated only the image condition across four mobile news topics. These conditions were no photograph, a relevant photograph without a face, a photograph with a negative affect display, and a photograph with a positive affect display. Two hundred sixty-eight university LISTSERV respondents and 50 Prolific international research panel respondents each judged four randomized unique image and topic combinations for emotion, news report value, perceived novelty, and report feature salience. Participants identified faces as the most salient feature of mobile news reports. Reports with an affect display were judged to have more emotion and perceived novelty than reports without an image, though they were viewed for less time. Positive affect displays were perceived to have greater emotion and report value. Perceived novelty predicted most of the variance of report value. Mobile news reports that included a photograph without a face were no different from no image in emotion or perceived novelty. They had only slightly greater report value. These results suggest that including innocuous images in mobile news may not increase reader interest in the related story topic. Faces are critically important to mobile news readers, and affect displays convey significant meaning for their viewers. Furthermore, positive affect may be more powerful than negative affect. Therefore, news and health communication may benefit from prioritizing positive visual messaging.
