Question

Quizplus · Accepted Answer

An illusion is a distorted perception of an actual stimulus, meaning it is not an accurate representation of reality. It differs from a hallucination, which is a perception of something that is not actually present and only exists in the mind of the viewer. Therefore, choice A is incorrect. Illusions also involve the interpretation of sensory input by the brain, but they are not limited to brain cells and can involve environmental factors as well. Therefore, choice B is also incorrect. Choice D is incorrect because illusions do not correspond directly to reality.
