Document Summary
Can help you become more aware of the nature of your own perceptual experiences. Perception depends on the properties of the sensory receptors (senses) Begins with the stimulus in the environment. Ends with conscious experiences of perceiving of the stimulus. 7 steps plus knowledge summarize major events occurring between time person looks at stimulus, perceives what it is and recognizes it. Neural processing understanding how neurons work -- how they interact with each other and operate within different areas of brain. When reflected light reaches the eye, its transformed as it is focused by the eye"s optical system (cornea front of eye) and lens (behind cornea) Information about tree (stimulus) is carried by light. Sensory receptors cells specialized to respond to environmental energy, with each receptors specialized to respond to a specific type of energy: visual respond to light. When they receive light reflected from tree transform environmental (light) energy into electrical energy.
