Answer:
Hypnotherapy.
Step-by-step explanation:
Hypnosis can be defined as a mental state that is trance-like and it is typically characterized by minimal peripheral awareness, vivid fantasy, highly focused attention (concentration) and an increased level of suggestibility.
Simply stated, hypnosis is a sleep-like state and as such can be used by psychologist or therapist to reduce the sense of pain, induce relaxation, strengthen certain behaviors etc.
Hence, one of the ways in which hypnosis can be administered by psychologists or therapists is through Hypnotherapy.
The use of hypnosis in psychotherapy and is practiced by licensed physicians and psychologists to treat conditions including depression, anxiety, post-traumatic stress disorder (PTSD), and eating disorders is referred to as Hypnotherapy.
