Document Summary

Distal stimulus: actual or real stimulus primary perception. Proximal stimulus: illusions of reality secondary perception. John locke s (1690) distinction between primary and secondary qualities. Secondary: the perceived quality of the object according to your brain. Sometimes the distal stimulus is there but we do not experience a percept. Sensation: the process by which physical energy patterns falling upon the sense receptor (the proximal stimulus) are transduced to nervous impulses. Perceptions: the process by which the nervous impulses sent from the sense receptors to the brain is interpreted (constructed) into a percept. Sensory deprivation y even your sense of self depends on sensory input y bexton, w. h. , heron, w. and scott, t. h. (1954) effects of decreased variation in the sensory environment. Different sound waves: amplitude (decibels) : physical measured and corresponds to loudness, frequency (hertz): measured in cycles per second and corresponds to pitch, complexity: corresponds to timbre (human voice)
