Document Summary
The perception of the tree is based on light reflected from the tree which introduces a central property of perception: light is reflected and transformed. Principle of transformation: stimuli and responses created by stimuli/ transformed between the environmental stimulus and perception. When the reflected light reaches the eye it is transformed as it is focused by the eyes optic system which forms a sharp image of the tree on the receptors of the retina: The cornea (at the front of the eye) Sensory receptors: cells specialized to respond to: receptor processes and transduction environmental energy with each sensory systems receptors specialized to respond to a specific type of energy: Auditory receptors to pressure changes in the air. Smell and taste receptors to chemicals entering the the skin nose and mouth. 2 things happen when visual receptors receive light. They transform environmental energy into electrical energy. They shape perception by the way to respond to stimuli.
