Abstract
To interact with others, one needs to infer other people’s intentions and actions. In order to do this, we have to rely on a set of social skills usually referred to the theory of mind, social attention, and social cognition. According to Baron-Cohen (1995), people are highly adept at using gaze cues to decode the behavioural intentions of others. Previous behavioural studies have shown that people have a tendency to attend to the location where another person is attending to (e.g. Driver et al. 1999). Our study investigates the role of auditory and visual cues within the initial stages of processing of socially relevant information. The aim of our study was to assess the individual contributions of the human voice and the body orientation to the direction of attention while perceiving other people. The study used adapted versions of Posner’s central and lateral cueing paradigms, which in previous studies have demonstrated that such social cues (gaze direction, head orientation) efficiently triggered shifts of a viewer’s visual attention (Driver et al. 1999; Langton & Bruce, 1999). Our study investigates how attention is oriented while perceiving human action and voice. Result will be discussed on the conference.
