Document Summary

It"s only at a higher level where attention starts to matter. Instead of people asking simple questions they asked complicated questions. If you increase the number of items, you increase the probability that you will make the wrong decision. Harder to make decisions about 15 things than 2. Explains taylors results in the terms of the decision process: the perceptuon isn"t more difficult as you get more things in the display it"s the decision process that is more difficult. It all happens automatically and its only later in the system that we get limitations (agrees with d & d) Is there any validity to this? (2) experiment: 4 things are as easy to perceive as 1, but you have to make 4 decisions and that is harder. First condition: say if theres a t or f in the display, he measured whether you were right or not (didn"t measure reaction time), used very brief display so that people make mistakes.
