Sensation and Perception

Sensation and perception are interrelated processes that are developed throughout the lifespan. Although they have a close relationship, sensation and perception have discrete qualities that differentiate one from the other. Sensation is defined as the process in which a sensory receptor is stimulated, producing nerve impulses that travel to the brain, which in turn interprets such impulses as a visual image, a sound, taste, odor, touch, or pain. The physical stimulus present in the environment emits energy that is absorbed by a sensory organ known as transduction , causing sensation. Perception refers to the occurrence when the brain performs organization of information it obtains from the neural impulses, and then begins the process of translation and interpretation. It is a vital process that helps us rationalize or make sense of the information related to the physical stimulus.

All perception involves signals that go through the nervous system , which in turn result from physical or chemical stimulation of the sensory system.
