Document Summary
Sensory information is all around us during every single second of our lies. Sense organs are constantly bombarded with sensory information that our brains sift through and process in order to determine what is important versus what can be ignored. We have five sense organs: eyes, nose, skin, ears, tongue. Sensory receptor cells- transforms physical energy or information into neural information. Examples are: eyes- light waves, ears-sound waves, nose-pick up molecules, tongue-register chemicals, and skin any force that physically presses it. Sensation- when these various forms of physical energy simulate our sense organs and this info. Is transmitted back to the central nervous center. Perception- refers to when our brains organize and interpret the sensations. Psychophysics- studies relations between the physical characteristics of stimuli and sensory capabilities, is concerned with two kinds of sensitivity: absolute limits of sensitivity, differences between stimuli. Absolute threshold of stimulus detected 50% of the time.
