While Matt is under hypnosis, the hypnotist tells him that he remembers being lost in a shopping mall as a young child. After being brought out of hypnosis, Matt is completely convinced that the incident occurred and describes it in detail. The hypnotist has successfully created _______. a. a posthypnotic suggestion b. posthypnotic amnesia c. a hidden observer who accurately reported a longrepressed memory d. a pseudomemory

Before choosing the correct option, let's make sure we understand the meaning of each term: a. A posthypnotic suggestion refers to a suggestion made to a person while they are under hypnosis, which is expected to influence their behavior after they are brought out of hypnosis. b. Posthypnotic amnesia occurs when a person under hypnosis is unable to recall specific information or events that took place during hypnosis after they are brought out of the hypnotic state. c. A hidden observer refers to a part of one's consciousness that is not directly controlled by the hypnotic process but can observe and report about experiences during hypnosis. This concept is often used in describing the phenomenon of individuals remembering repressed memories during hypnosis. d. A pseudomemory is a fabricated or distorted memory that a person believes to be true, even though it did not actually happen. This can happen during a hypnotic session when a person is highly suggestible and might adopt a suggested memory as their own.

In the given situation, Matt is under hypnosis and the hypnotist tells him about an incident from his childhood. After being brought out of hypnosis, Matt believes that the incident occurred and can describe it in detail. It seems that the hypnotist has successfully influenced Matt's memory.

Considering the meanings of each term and evaluating the situation, it becomes clear that the hypnotist has successfully created a pseudomemory (option d). Matt is recalling a fabricated memory, which he believes to be true but did not actually happen. The other options do not accurately describe this situation.
