Document Summary
The smallest detectable difference b/w two stimuli, or them minimum change in a stimulus that enables it to be correctly judged as difference from a reference stimuli. The principle that the jnd is a constant fraction of the comparison stimulus. A principle describing the relationship b/w stimulus and resulting sensation such that the magnitude of subjective sensation increases proportionally to the logarithm of the stimulus intensity. (later found incorrect) A stimulus intensity grows larger, larger changes are required for changes to be detected by the perceiver. A reduction in response caused by prior or continuation stimulation. A receptor that converts physical energy from the environment into neural activity. The idea that the mind produces ideas that are not derived from external sources, and that we have abilities that are innate and not learned. The idea that mind and body both exist.
