2. Psychological Theories of Deja Vu
Several psychological theories have been proposed to explain the causes of deja vu. These theories can be broadly classified into three categories:
Memory-Based Theories
These theories suggest that deja vu is caused by a temporary malfunction in the memory system. Specifically, they propose that deja vu occurs when a new experience is mistakenly recognized as an old memory.
Perception-Based Theories
These theories propose that deja vu is caused by a temporary mismatch between the way the brain perceives and processes new information. Specifically, they suggest that deja vu occurs when the brain receives conflicting sensory information, leading to a feeling of familiarity.
Neurobiological Theories
These theories propose that deja vu is caused by abnormal activity in certain brain regions, particularly the hippocampus and the temporal lobes. These brain regions are involved in memory, perception, and the sense of familiarity.
