Document Summary
Practical reasons: prosthetic devices repair damaged sense organs build artificial realities design sensory environments make technology easier to use engineering. The road begins with stimuli in the environment and ends with the behavioural responses of perceiving, recognizing, and taking action. We begin with an environmental stimulus; the object that the person is perceiving is about the light that is being reflected. When the reflected light reaches the eye it is transformed as it is focused by the eyes optical system, which is the cornea at the front of the eye, and the lens directly behind it. The principle of representation: states that everything a person perceives is based not on direct contact but stimuli but on representations of stimuli that are formed on the receptor and the activity of the persons nervous system. Sensory receptors are cells specialized to respond to environmental energy with each sensory systems receptors specialized to respond to a specific type of energy.
