Abstract: | Previous research has suggested that a singly presented facial stimulus having a direct gaze holds spatial attention. This study examined whether facial stimulus having a direct gaze can also capture spatial attention in a relative dot-probe paradigm (facial stimulus having a direct gaze was presented concurrently with that having an averted gaze). The results showed that participants oriented their spatial attention to a facial stimulus having a direct gaze rather than to that with an averted gaze. This attentional bias depended on gaze-perception mechanisms as observed in the lack of attentional bias to a direct gaze from unnatural-looking eyes (i.e., white pupil/iris and black sclera). These findings raise the possibility that the attentional effect implicated in the perception of a direct gaze is induced regardless of the stimulus context. |
