Document Summary

Basic definitions: sensation: the process by which our sense organs respond to and translate stimuli into nerve impulses sent to the brain, perception: organizing stimulus input into meaningful patterns. Perception stimuli activate sensory receptors sensory receptors translate information into nerve impulses specialized neurons analyze stimuli features stimulus pieces are reconstructed and compared to stimuli in memory: perception is then consciously experienced. Psychophysics definition: the study of sensitivity to stimuli absolute limits dimmest light in which we can see objects softest sound we can hear recognizing differences between. Stimuli smallest difference in brightness detectable recognizing differences between tones. Stimulus detection the absolute threshold: the lowest intensity at which a stimulus can be detected 50% of the time. Theory decision criterion: a personal standard of certainty before a person will say that they detect a stimulus: affected by: Whether the individual is conservative or bold. Increasing rewards for hits or costs for misses.
