Five studies demonstrated that private self-consciousness is associated with nonconscious, automatic behaviors. In 2 studies, high but not low self-conscious individuals walked more slowly following exposure to an implicit elderly prime. In a 3rd study, high but not low self-conscious individuals showed improved performance following exposure to a subliminal success prime relative to a subliminal failure prime. In a 4th study, subliminal exposure to an angry prime was shown to increase blood pressure relative to a relax prime. In a final study, the latter effect was shown to be true only for high self-conscious individuals and only for subliminal presentations. Results are discussed in terms of their implications for understanding a variety of effects associated with self-consciousness and self-awareness.
