The power of (surreptitiously) mentioning your mentor’s name: Subliminal priming of mentor’s name modulates N170 responses to blurred faces

Using the event-related potentials (ERPs) technique and subliminal priming paradigm, the present study examined the influence of mentioning a mentor's name on graduate students. Fifty-eight graduate students were subliminally primed by mentor and stranger names before making pressure judgments of a series of unrelated blurred facial photos with neutral emotion. The face-sensitive N170 components were analyzed according to the pressure judgment × name prime conditions. The results showed that relative to stranger names, subliminal priming of mentor's name could modulate students' N170 reactions during facial processing. Specifically, the mentor-name priming attenuated N170 amplitudes for high-pressure judgment trials on the right hemisphere but heightened the overall N170 responses on the left hemisphere. Behavioral results also showed that the mentor-name priming slowed students' reaction time during pressure judgments; in addition, students' attitudes towards mentors were correlated with N170 amplitudes on high-pressure judgment conditions. These findings provided neuroscientific evidence demonstrating the psychological significance of mentors to graduate students. Theoretical and practical implications were also discussed.
