Show answer and explanation

Correct answer: (A) Erroneous perceptions; (D) Incorrect perceptual hypothesis

Explanation

An illusion is a misperception of a real stimulus. It can be described as an erroneous perception, and in Gregory's view it arises from an incorrect perceptual hypothesis. Schemas and perceptual constancies are normal mental structures and processes, not illusions.
