Study summary

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.

Read the detailed description

To test investigators' hypothesis, investigators adopted the self-referential task and fMRI to investigate the neural representation of self in depression patients, and compared with healthy control.

What researchers measure

Primary outcomes

  1. Neural representation of self

    We adopted the self referential task. In the task, participants were asked to judge whether a given word was appropriate to describe oneself (self-judgement condition), a celebrity (other-judgement condition) by pressing one of the two buttons with the index or middle finger. For judgments of each target person (i.e, self and celebrity), there were 3 categories of words describing the mental (personality traits, such as hard-working, friendly), physical (physical attributes, such as black hair, big eyes) and social (social roles, such as student, American) dimension of person knowledge. The fMRI task contained 6 runs, with 4.6 minutes per run. This paradigm and task allowed us to investigated the neural representation of self by comparing the BOLD activity under self-judgement condition with BOLD activity under other-judgement condition.
