Document Summary
Chapter 18 - sensation and perception - add from slides. There are sounds sensed by us all the time, but we only consciously perceive what the person talking to us is saying. Weber"s law: absolute difference is not what matters, but rather the percentage difference between two stimuli. A candle lit in an already well lit room won"t be noticed, but it will in a dark room. Same visual stimulation can mean different things depending on the context. The symbol in the middle of the two words are identical, but we can read it as either an h or an a depending on the surrounding letters. If you stare at it long enough, you will see a dog with its face down on the sidewalk walking towards a tree. Have to use both bottom-up and top-down processing to figure out what this note says.
