Abstract(in English) Facial gaze seems to be very important for understanding others' mind in human communication. Automatic or reflexive attentional shift in response to another individual's gaze direction has been reported. In this study, we examined temporal thresholds to be seen whether direction cue in line drawing stimuli shows right or left side, in face gaze cue, horizontal line cue, and arrow cue, by presenting in different stimulus durations (Experiment 1). This showed the temporal limit in face gaze was much faster than one in line cue and arrow cue. Also, we tried to determine temporal point supraliminally or subliminally that the cue direction can be perceived with or without awareness. We next examined whether automatic attentional shift to a target can occur with or without awareness of the gaze direction, as a function of presentation duration of face gaze cue (Experiment 2). The reaction time needed to localize the target was consistently shorter for valid than invalid gaze cues, but the reaction times were almost constant both in subliminal and suplaliminal duration times.
