PSYA01H3 Study Guide - Final Guide: Episodic Memory, Explicit Memory, Operant Conditioning
Document Summary
Sensation detection of simple properties of stimuli (brightness, colour, warmth, sweetness) Perception detection of objects, locations, movements and backgrounds. Transduction sense organs convert energy from environmental events into neural activity, sense organs convert into neural firing. Receptor cells release chemical transmitter substances that stimulate other neurons, altering the rate of firing. Distinguish between 7. 5 different colours action potentials cannot be altered. Anatomical coding brains has no direct information about physical energy, it uses anatomical coding: interpret location and type of sensory stimulus when nerve fibers are active body surface coding is anatomical. Temporal coding coding of information in terms of time rate of firing at a faster/slower rate according to intensity of the stimulus, axon can communicate quantitative information to the brain. Anatomical location of stimulus temporal intensity of stimulus. Weight factor 1 in 40, brightness of white light 1 in 60 weber fractions. Gustav fechner used jnd to measure peoples sensations.
