Abstract: Perspective taking refers to the mental process in which an individual image or speculates the views and attitudes of others from the perspective of others or their situation. A review of relevant studies found that: (1) Whether there is egocentrism bias in perspective taking is still controversial; (2) The egocentrism bias of perspective taking does not always exist, which may be due to the time pressure and the requirement of specific types of tasks; (3) The presence of others affects the egocentrism of perspective taking, and the effect is automatic and independent of task type; (4) The cognitive mechanism of perspective taking mainly includes interactive alignment, memory extraction and probability calculation. Future research needs :(1) Integration of the existing computational models; (2) To further explore the relationship between perspective taking ability and Theory of Mind; (3) Explore the role of private information in the perspective taking; (4) To improve the ecological validity of opinion selection research; (5) Using different technical means for convergence verification.
