Document Summary

Sensation process through which the senses detect visual, auditory and other sensory stimuli and transmit them to the brain. Perception process by which sensory information is actively organized and interpreted by the brain. Perception and sensation work together: example blind spot- where the optic nerve is. You don"t notice the blind spot because your brain fills in the missing spots. Sensation gives us the visual ques, while perception fills in the blanks. Sensory transduction converting information in environment into neural impulses. There needs to be a certain level of stimuli before we notice it. Absolute threshold the difference between not being able to perceive a stimulus and being able to just barely perceive it: the minimum amount of sensory stimulation that can be detected 50% of the time. Difference threshold (jnd just noticeable difference) the smallest increase or decrease in stimulus that is required to notice a difference.
