Abstract
Using event-related potentials, this study investigated the interplay between self-deception and varying motivations in influencing deceptive behavior. Participants in either the self-deception or nonself-deception condition were instructed to make deceptive decisions under different motivational contexts. Behavioral responses and neural activity were recorded throughout the decision-making process. Behaviorally, there were no significant differences in deception proportions between the self-deception and nonself-deception conditions under egoistic or mixed motivations. However, under altruistic motivation, participants in the self-deception condition engaged in more deceptive behavior compared to those in the nonself-deception condition. Event-related potential results revealed no significant differences in P2 and N2 amplitudes between the self-deception and nonself-deception conditions under egoistic or mixed motivations. However, under altruistic motivation, the self-deception condition was associated with reduced P2 amplitudes and more negative N2 amplitudes relative to the nonself-deception condition. Additionally, no significant interaction in P3 amplitudes was found between self-deception and different motivations. These findings suggest that the effect of self-deception on deceptive behavior is modulated by different motivations. Specifically, egoistic or mixed motivations might be associated with a self-serving tendency in deceptive behavior, while altruistic motivation appeared to enhance deceptive behavior in the self-deception condition, potentially to foster a prosocial image.
