Document Summary
> level of stimulation required for a stimulus to be detected 50% of the time. > smallest amount of change in stimulation required for it to be detect. Example, take a hot bath before hot yoga & it won"t feel that hot. > decision processes are also involved in the detection of sensory input by setting criteria for detection. Example, thinking you heard the phone ring when it didn"t. Hit = it did happen & you did react. Miss = it did happened & you didn"t notice. False alarm = you thought it was happening but it wasn"t. Correct rejection = it didn"t happen & you didn"t think it happened. > awareness is not necessarily required for perception. > occurs when sensory information is processed without awareness. Evidence that the subliminal perception of visual information can influence behavior & thought. Subliminal presentation of a face increases ratings of attractiveness of that face relative to others.
