Quizplus · Accepted Answer

The drug most likely interfered with size constancy, which is the ability to perceive the size of an object accurately regardless of its distance from the observer. Therefore, the student perceived their hand as giant even though it was only close to their face. This distortion of perception is consistent with the effects of drugs that alter depth perception.
