Document Summary
Doctrine of specific nerve energies- different sensations stimulate different pathways into the brain. Synesthesia- when one kind of sense provokes other non-associated feelings like seeing the color blue and tasting cherries. Absolute threshold- the smallest amount of energy that people can reliably detect: this is not a reliable because people are inconsistent during trials. Difference threshold- the smallest difference of change that humans can detect. Signal detection theory- a process that can be divided into two different processes. Sensory process depends on the intensity of the stimuli. Decision process- influenced by an observer"s response bias. Sensory deprivation- when the senses are blocked off and the brain substitutes its own perceptions instead of incoming stimuli. Hue- related to the wavelength and color of light. Brightness- the intensity of the color corresponds to the amplitude of the waves. Saturation- the complexity of light, how wide or narrow\ the wavelength of the light is.
