This study mainly discusses the influence of feedback type and feedback valence on self-deception. Experiment 1 uses prospective paradigm to explore the influence of different valence of fuzzy feedback on self-deception. The results show that compared with the group without answer prompt, the participant in the group with answer prompt significantly improve the prediction scores in the second stage of test 2 under the condition of positive fuzzy feedback (the degree of self-deception is aggravated). Experiment 2 explored the influence of accurate feedback with different valence on self-deception. The results showed that compared with the group without answer prompt, the participants in the group with answer prompt significantly reduced the prediction scores in the second stage of test 2 under negative accurate feedback conditions. Experiment 3 uses ERP technology to explore the internal mechanism of feedback type and feedback valence affecting self-deception. The results show that self-deception under fuzzy feedback conditions induces larger P2 components and smaller N1 and N400 components. The research found that self-deception has a greater effect in the frontal area. These results show that positive feedback may promote the generation of the self-deception, while negative feedback weakens the generation of the self-deception. Positive fuzzy feedback can further promote the generation of individual self-deception. These findings also indicate that the mechanism behind self-deception may be self-expansion.
