Document Summary
How many thing that are out there can you perceive at once. Miller: the span of short term memory magic number is 7 (+/- two) You can perceive them all, but you cant remember them in your short term memory (short term memory problems) Output of interference: you see all 12, you only remember 7, but when you try and repeat them back the experimenter you forget them (start saying the, by the 5th, cant remember the last few things) Conclusion: perception isn"t within our limits, we can perceive everything, we just cant contain it in our short term memory. No real perceptual attention everything gets in. When the stimulus is gone- perception is stopped so when you delay the cue, you are tapping into short term memory, the longer you wait the more performance will go down. We need someone to answer the question does perception ends when the cue ends. They presented two rows of 8 letters.
