Document Summary

Perception does not just happen end result of complex processes. Perception of world = small part of what is happening as you perceive. Perceptual process sequence of processes that work together to determine experience of and reaction to stimuli in environment (stimulus, electricity, and experience and action) Stimulus what is in the environment, what we pay attention to, what stimulates our receptors. Environmental all things in environment that we can potentially perceive. Attended changes from moment to moment shift of attention: on receptors image of immediate surroundings created on receptors of retina (0. 4 mm thick network of light-sensitive receptors + other neurons lining back of eye) Stimulus transformed into another form image in retina representation. Electricity electrical signals (in nervous system) created by receptors and transmitted to the brain. Transduction transformation of 1 form of energy into another form. In nervous system when energy in environment (i. e. light energy, mechanical pressure, chemical energy) transformed into electrical energy.
