About

To be aware of oneself as a unique entity in the world occurs early in human development and is the prerequisite of normal social functioning. The disturbance of self representation characterizes a variety of mental disorders such as autism and schizophrenia. Negative self-bias was found to serve as the core cognitive mechanism of depression disorder. However, there was no evidence to show the reason lead to negative bias. In the current study, investigators hypothesized that the blurring self representation was the neural correlates in depression disorder.
