As a terrestrial animal, the environment provides abundant resources for the survival and reproduction of human beings. In the process of survival and reproduction, the human ability of space perception plays an important role. In the environment with abundant perception cues, space perception depends more on external cues; in the environment with limited cues, individuals’ space perception can also be accurate. Researchers have found that it is intrinsic bias, which is the internal cues that help individuals perceive surrounding environment. Based on the review of human perception cues, this paper will review the proposal, influence and influence factors of intrinsic bias and discuss it at the end of the paper.
