Document Summary

Mixing of the senses (experience sound as colour) When he heard a higher tone, he produced a brown strip with a sweet and sour flavour. Converting energy (light, sound waves, vibrations, chemicals) into neural impulses (action potentials) There is outside energy that comes in from environment. Select, organize, interpret sensory input (give meaning to) Relation between physical stimuli and our perception of those stimuli. Dividing point between energy levels from detectable to non detectable. The intensity level at which a person can detect a stimulus 50% of the time. The minimum change in stimulation that senses can detect. The size of jnd is a constant proportion (fraction) of the sixe of the initial stimulus. The smaller the constant, the more sensitive we are to change in that modality. The perceived intensity is not directly proportional to actual intensity (fechner"s law) Larger and larger increases in stimulus intensity are required to produce perceptible increments in the magnitude of sensation.
