Final answer:
Hypnotic amnesia is the phenomenon where individuals cannot recall what transpired during hypnosis, despite hypnosis typically allowing clear memory recall.
Step-by-step explanation:
After being hypnotized in a therapy session, Juan says that he can't remember what went on. This phenomenon is known as hypnotic amnesia. Hypnosis is a state of extreme self-focus and attention, often used in a therapeutic setting to alter thoughts and perceptions. It's important to differentiate between hypnosis as an empirically based therapeutic approach and its portrayal in entertainment. Although people often recall the hypnotic experience, hypnotic amnesia can occur when suggestions made during hypnosis lead to the subject not remembering certain events or information. This can happen due to the heightened suggestibility of individuals under hypnosis.
