PS101 Study Guide - Olfactory Bulb, Neuroticism, Synesthesia
Document Summary
Sensation: the detection of physical energy emitted or reflected by physical objects, occurs when energy in the external environment or the body simulates receptors in the sense organs. Perception: process by which the brain organizes and interprets sensory information. Doctrine of specified nerve energies (muller: principle that different sensory modalities exist because signals received by the sense organs stimulate different nerve pathways leading to different areas of the brain. Could essentially if technology existed allow you to see things as a result to noise. If possible allows for sensory substitution: sensory crossover also occurs in synesthesia where simulation of one sense consistently evokes the sensation of another. Psychophysics: field concerned with how the physical properties of stimuli are related to our psychological experience of them. Absolute threshold: the smallest quantity of physical energy that can be reliably detected by an observer (50% of the time, senses are sharp but only tuned into narrow band of physical energies.
