Deja vu is a French word, which literally means? Have you seen it? There are several varieties, including Degas Viku (experienced), Degas Senti (thought) and Degas Vesit (visited). French scientist Emily? Pollack was one of the first people to study this strange phenomenon. He named this theme in 1876.
People often say that they have experienced hallucinatory memories, but they are not really hallucinatory memories. Researchers have their own definitions, but hallucinatory memory is usually described as a feeling, that is, knowing that they have never seen or experienced something, but they always feel that they have seen or experienced it. The most common misuse of the term "hallucinatory memory" seems to be related to a hunch that someone feels that something is about to happen, but in fact it has already happened. A very important difference between them is that hallucinatory memory is experienced during the event, not before. Pre-impressions (if they are true) indicate what will happen in the future, not what has been experienced. Hallucinations caused by diseases or drug abuse sometimes enhance people's consciousness and are confused with hallucination memory. False memory caused by schizophrenia may also be confused with hallucinatory memory. Unlike real hallucinatory memories (usually lasting only 10 to 30 seconds), these false memories or hallucinations may last longer.
It is difficult to define the type of hallucinatory memory. People who have studied hallucinatory memory apply their own classifications and differences? Each usually relies on a specific theory about the causes of hallucinatory memory. Allen? Brown, a professor of psychology at Southern Methodist University and the author of Illusory Memory Experience: Miscellanies of Cognitive Psychology, divides hallucination memory into three categories. He believes that there are three reasons for inducing hallucination memory, namely, biological dysfunction (such as epilepsy, implicit familiarity and separation perception). In 1983, Dr. Vernon Nepp, director of the Pacific Neuropsychiatric Institute in Seattle, proposed that hallucinatory memory should be divided into four subcategories, including epilepsy, subjective abnormality, schizophrenia and association.
We can divide hallucinatory memories into two categories:
Associative hallucination memory
In fact, the most common type of hallucination memory that normal healthy people can experience is associative hallucination memory. What you see, hear, smell or experience will stimulate your feelings and make you associate it with what you have seen, heard, smelled or experienced before. Many researchers believe that this type of hallucinatory memory is based on the experience of memory and assume that it is caused by the memory center of the brain.
Biological hallucination memory
Patients with temporal lobe epilepsy also have a high frequency of hallucinatory memories. Before the attack, they usually have strong hallucinatory memories. This provides a slightly more reliable method for researchers to study hallucinatory memory, and they have been able to determine the areas in the brain that produce these hallucinatory memory signal types. However, some researchers say that this type of hallucinatory memory is completely different from typical hallucinatory memory. People with this experience may really believe that they have experienced the same situation before, instead of getting a fleeting feeling. When hallucinatory memories appear, there are also some signs of major mental disorders, including anxiety, depression, dissociative disorder and schizophrenia.
