Looming fear stimuli broadens attention in a local-global letter task.

Abstract

This chapter provides an overview of the literature on emotion and global/local processing and presents an empirical study exploring how the combination of motion and emotion influences the focus of attention. In two experiments, fear-related pictures either loomed toward the observer or were stationary, and in one of these experiments the emotional content was masked (i.e., scrambled pictures). In the context of fearful pictures, it was expected that the additional element of looming motion would further focus attention based on looming motion's behaviorally urgent properties. However, the combination of a fearful image and looming motion was shown to broaden as opposed to narrow attention. This effect did not occur with simply neutral/looming or fearful/static images. Further, the separation of the emotional content from looming motion (scrambled pictures) revealed no effect on attentional breadth. This suggests that it is the unique combination of the fear-related content and the looming motion, which is broadening attention.
