Attentional Selection of Social Features Persists Despite Restricted Bottom-Up Information and Affects Temporal Viewing Dynamics.


ABSTRACT: Previous studies have shown an attentional bias towards social features during free-viewing of naturalistic scenes. This social attention seems to be reflexive and able to defy top-down demands in form of explicit search tasks. However, the question remains whether social features continue to be prioritized when peripheral information is limited, thereby reducing the influence of bottom-up image information on gaze orienting. Therefore, we established a gaze-contingent viewing paradigm, in which the visual field was constrained and updated in response to the viewer's eye movements. Participants viewed social and non-social images that were randomly allocated to a free and a gaze-contingent viewing condition while their eye movements were tracked. Our results revealed a strong attentional bias towards social features in both conditions. However, gaze-contingent viewing altered temporal and spatial dynamics of viewing behavior. Additionally, recurrent fixations were more frequent and closer together in time for social compared to non-social stimuli in both viewing conditions. Taken together, this study implies a predominant selection of social features when bottom-up influences are diminished and a general influence of social content on visual exploratory behavior, thus highlighting mechanisms of social attention.
