Gaze orientation induces activation of relevant brain regions,presents differences in specificity and time course,and is exhibited in patients with brain injury.However,the components of activated event-related potential remain controversial.Previous studies of behavior and cognitive neuroscience related to gaze orientation investigated conscious attention of visual orientation.The present study explored gaze orientation processing-induced event-related potential components and changes with time using reflective orientation of visual attention under a reflective attention cue paradigm.Visual attention processing of gaze orientation was recorded using event-related potential and electroencephalographic recording.Results demonstrated that the reflective attention cue task evoked early directing attention negativity and anterior directing attention negativity,but did not trigger late directing attention positivity.These results suggest that reflective attention occurs over a short time of visual stimulus presentation.During the early stage of attention processing,early directing attention negativity and anterior directing attention negativity were detected,but late directing attention positivity did not occur.These results confirmed reflectivity and time-course superiority of gaze orientation attention processing.
