Document Summary
Perception is unique, it is subjected to us. Sensation is the stimulation of sense organs -> is the same for everyone (uniform) How we take energy from the world can convert it to neuro impulses in the brain. Ignore 90% of stuff around us, and only 10% is what we pay attention to because paying attention to everything would cause sensory overload. Based on unconsciousness - the 10% is unique to us (subjected to what we want to pay attention to based on various factors) How we organize, select, understand, and see -> perception. Absolute threshold is the point at which the min. amount of energy that our stimulus activation can detect at 50% of the time (we have sense it ) Once we have absolute threshold, it becomes the just noticeable difference. Higher intensity needs to be added in order to notice the difference. However we have our own unique absolute threshold.
