Higher Self-Control, Less Deception: The Effect of Self-Control on Deception Behaviors.

The self-control ability and self-control resources have a different influence on deception, but the cognition mechanism of this different influence has not been described yet. In this study, the event-related potentials (ERPs) technique was utilized to conduct two experiments exploring the effects of self-control ability and self-control resources on deception from two approaches. In Experiment 1, participants with different levels of self-control ability performed a visual perception task to measure deception and deception tendencies. The results revealed that individuals with low self-control ability exhibited more deceptive behaviors than did individuals with high self-control ability. Furthermore, individuals with high self-control ability evoked larger N2 and smaller P3 amplitudes than did individuals with low self-control ability. Experiment 2 involved selecting individuals with medium self-control ability. The Stroop task and a visual perception task were employed to investigate the influence of self-control resources on deception. The results showed that the depletion of self-control resources facilitated smaller N2 and larger P3 amplitudes than did non-depletion of self-control resources. In conclusion, these results suggest that individuals with high self-control ability are less likely to deceive others in order to obtain more benefits. When individuals have sufficient self-control resources, they resist temptation and reduce deception behaviors. Deception and deception tendencies may be more likely in people with low of self-control and whose self-control resources are depleted. In people with moderate self-control, deception was still regulated by self-depletion.
