Document Summary
Jan 12/2016: overview: processes involved in perception, transduction. Changing energy from one form to another. When talking about vision, we have light energy which is a form of electromagnetic radiation. Distal stimulation: light fell on box, is bounced into our eye, bla(cid:272)k thi(cid:374)gs do(cid:374)"t refle(cid:272)t a(cid:374)(cid:455)thi(cid:374)g, (cid:449)hite refle(cid:272)ts e(cid:448)er(cid:455)thi(cid:374)g. Proximal stimulation: we respond to the light that is on our eye, not the light bouncing off the box, you respond to light reflecting in your eye. Hearing: when a molecule bounces off of another molecule causing energy (mechanical energy, mechanical energy becomes electrical energy, interpretation. A (your toe) to point b (your mind)) The physiology of perception: overview: the neuron and its parts. Axon: ascend electric message down the cell (sending message away, width of axon (narrow or big) Size of the axon determines how quickly the electric charge can travel down the axon. Sometimes the body has to prioritize because of this.
