The aims of this study were to investigate the differences in responses for varied self-control experiment paradigms, and to explain these differences on the basis of social cognitive semantic conflicts and social cognitive reaction conflicts. Using two mixed experimental designs, the study incorporated the stop signal and single-attribute implicit association test paradigms into a self-control experiment paradigm to investigate self constructs. Social cognitive semantic conflicts and social cognitive reaction conflicts were significant at 250 - 300 ms post-stimulus. According to different genders, self-control mechanism has universal significance.
