In an experiment, hypnotized subjects are told to scratch their ear if they hear the word "psychology" mentioned later. The fact that they do so only if they think the experiment is still under way most clearly supports the theory that hypnosis involves:a. dissociation.
b. neuroadaptation.
c. role playing.
d. hypnagogic sensations.

The correct answer is C. Role Playing.

Explanation:

Role Playing in psychology is used to enhance certain skills to handle difficult situations. In other words, role playing can be defined as changing one's behavior to adapt to a new role.

This theory was first introduced in 1941 by RW White. This man said that hypnosis is basically like a role that people are playing i.e. they are acting if they are being hypnotized.
