Document Summary

Is there a picture of a bakery: ability to recognize this information and identify within fast time period. Recognition: typically, fast, effortless, prone to error, why, why do we make mistakes, model of word recognition: feature nets, common approach in cognitive psychology. Finding #1: pop-out search: *easy to find red circle pops out at you, final picture is harder because your attention doesn"t immediately go to it, fast pop-out search. When all items except the target share the same feature, target is easy to find, regardless of the number of distracting items: slow conjunction search. Target does not possess any unique features and can only be identified based on a conjunction of two or more features. The more distracting items there are, the slower search is: suggests distinct stages of processing for features, and conjunctions of features, at feature stage, all features processed in parallel (i. e. , simultaneously).
