Affective Priming Enhances Gaze Cueing Effect

Other's gaze direction triggers a reflexive shift of attention known as the gaze cueing effect. Fearful facial expressions are further reported to enhance the gaze cueing effect, but it remains unclear whether this facilitative effect is specific to gaze cues or the result of more general increase in attentional resources resulting from affective arousal. We examined the effects of affective priming on the cueing effects of gaze and arrow stimuli in the Posner cueing task. Participants were primed with two types of briefly presented affective stimuli (neutral, threatening), and the target location was cued either by an arrow or a gaze cue in a neutral face. Gaze cues were preceded by the same face with its eyes closed or directed to the viewer. Study 1 (n = 26) assessed the cueing effect using manual key press, and Study 2 (n = 30) employed gaze-contingent eye tracking techniques to assess the cueing effect using time to first fixate the cued target location. Both studies found that threatening priming significantly enhanced the cueing effects of eye gaze but not arrow stimuli. The results therefore suggest that affective priming does not facilitate general attentional orienting, but the facilitation is more specific to social cues such as eye gaze.

Automated summary

The study found that threatening priming significantly enhanced the cueing effects of eye gaze but not arrow stimuli, suggesting that affective priming does not facilitate general attentional orienting, but the facilitation is more specific to social cues such as eye gaze.
