PSYA01H3 : Quick-review of chapter 5 terms
Document Summary
The detection of the elementary properties of a stimulus. Perception detection of the more complex properties of a stimulus, including its location and nature, involving learning. The conversion of physical stimuli into changes in the activity of receptor cells of sensory organs. Neuron that directly responses to a physical stimuli. Anatomical coding a means by which the nerves system represents information; different features are coded by the activity of different neurons. A means by which the nervous system represents information; different features are coded by the pattern of activity of neurons (firing faster/slower) Just-noticeable difference (jnd) the smallest difference between two similar stimuli that can be disguised; also called threshold. Ratio between a just-noticeable difference and the magnitude of a stimulus; reasonably constant over the middle range of most stimulus intensities. The point at which a stimulus, or a change in the value of a stimulus, can be detected.
