Combining social cues in attention: Looking at gaze, head, and pointing cues

Social cues bias covert spatial attention. In most previous work the impact of different social cues, such as the gaze, head, and pointing cue, has been investigated using separated cues or making one cue explicitly task relevant in response-interference tasks. In the present study we created a novel cartoon figure in which unpredictive gaze and head and pointing cues could be combined to study their impact on spatial attention. In Experiment 1, gaze and pointing cues were either presented alone or together. When both cues were present, they were always directed to the same location. In Experiment 2, gaze and pointing cues were either directed to the same location (aligned) or directed to different locations (conflicted). Experiment 3 was like Experiment 2, except that the pointing cue was tested alongside a head-direction cue. The results of Experiment 1 showed that the effect of the gaze cue was reliably smaller than the pointing cue, and an aligned gaze cue did not have an additive benefit for performance. In Experiments 2 and 3, performance was determined by the pointing cue, regardless of where they eyes were looking, or the head was directed. The present results demonstrated a strong dominance of the pointing cue over the other cues. The child-friendly stimuli present a versatile way to study the impact of the combination of social cues, which may further benefit developmental research in social attention, and research in populations whose members might have atypical social attention.
