PS101 Chapter Notes - Chapter 6: Telepathy, Inattentional Blindness, Taste
Document Summary
Sensation: the detection of physical energy emitted or reflected by physical objects: occurs when energy in the external environment or the body stimulates receptors in the sense organs. Perception: process by which the brain organizes and interprets sensory information. Doctrine of specific nerve energies (m ller): principle that different sensory modalities exist because signals received by the sense organs stimulate different nerve pathways leading to different areas of the brain. If possible, allows for sensory substitution: sensory crossover also occurs in synesthesia where stimulation of one sense consistently evokes a sensation in another. Sensation begins with the sense receptors, which convert the energy of a stimulus into electrical impulses that travel along nerves to the brain. Separate sensations can be accounted for by anatomical codes (as set forth by the doctrine of specific nerve energies) and functional codes in the nervous system.
