Final answer:
According to the social-cognitive theory of hypnosis, those who consider hypnosis a social phenomenon would contend that hypnosis is an altered state of consciousness, hypnotic phenomena are unique to hypnosis, and hypnotized subjects are no longer motivated to act as instructed.
Step-by-step explanation:
The social-cognitive theory of hypnosis sees people in hypnotic states as performing the social role of a hypnotized person. This theory suggests that a hypnotized person's behavior is not an altered state of consciousness, but rather the fulfillment of social expectations. Therefore, those who consider hypnosis a social phenomenon would contend that all of these statements are true - hypnosis is an altered state of consciousness, hypnotic phenomena are unique to hypnosis, and hypnotized subjects are no longer motivated to act as instructed.
