The sense of social agency in gaze leading
- 21 Downloads
Social interactions entail reciprocal reactions where one’s communicative acts triggers responses in others. Fluent interpersonal exchange relies on the ability to discriminate behaviors produced by others that are responses to one’s actions, thus involving a social sense of agency. Given the pivotal role of gaze in human communication, we propose to use gaze following as a model for studying the sense of agency in social actions. The experiment investigates the influence of sensory expertise and timing of the action’s effects by comparing feedback provided by a human avatar versus a nonfigurative animated object (an arrow) and by varying the control exerted by participants’ gaze on the feedback (avatar vs arrow). Results revealed a linear relationship between the judgement of agency and feedback latencies and higher agency discriminating performances with the avatar. These outcomes suggest that classical cognitive accounts of the sense of agency can be expanded to the realm of social actions and provide important information for designing virtual agents to train social gaze interactions.
