Question

Quizplus · Accepted Answer

Sensations occur when a stimulus activates a receptor, causing an impulse that is processed by the brain. This is the basic process of sensation, which leads to perception and eventually to the experience of conscious awareness. Option B is incorrect as illusions are not true sensory experiences. Option C is also incorrect as perception is the processing of sensory information, which is already a step beyond basic sensation. Option D is incorrect as the reaction comes after sensation, not before.
