3、ess refers to the inner subjective state of individual when he is aware of himself. And it can influence emotion experience, making emotion experience more intensive or dull. In addition, self-awareness effect in emotion

4、 experience is modulated by standards, such as emotion standard and individual standard. The present study aimed to investigate how emotion experience changed in the condition of self-awareness or standards, especially t

5、he neural mechanism. Therefore, the present study included three ERP experiments, adopting a mirror to manipulate self-awareness. There were two groups (high self-awareness, low self-awareness) in Experiment 1, which wer

6、e asked to access their emotion experience after seeing emotional pictures. The purpose of Experiment 1 was to examine whether self-awareness strengthened emotion experience or not. Then, based on Experiment 1, Experimen

7、t 2 was used to discover how self-awareness effect changed when there was an emotional standard. Experiment 3 was to explore the role of social standard in emotion experience, trying to expose the essence of standards. T

8、he results were as follows: (1) The scores in high self-awareness, which came from subjective reporting, was significantly higher than that in low self-awareness. And, there was also a corresponding increase in amplitude

9、 of a frontal late positive potential component (LPP) in high self-awareness, which was compared with low self-awareness. (2) When setting up an emotional standard, neither behavior data nor frontal LPP showed significan

10、t difference between high self-awareness and low self-awareness. (3) Self-awareness induced larger frontal LPP amplitude relative to social standard. (4) In the early attentional stage, high self-awareness elicited large

11、r P2 than low self-awareness and other awareness, while low self-awareness and other awareness induced greater N2. (5) No matter what context was, negative emotion elicited larger P300 amplitude than positive and neutral

12、 emotion, and this effect on parietal LPP amplitude was also pronounced. In summary, whatever the condition was, individuals are able to code and process emotional stimuli effectively. Moreover, self-awareness can enhanc

13、e the intensity of emotion experience because it facilitates individual to focus on his subjective behavior. However, due to self- regulation and emotional regulation, emotional standard and social standard will impair e
