Document Summary
*** notes include diagrams and images used in class for explanation *** Psyb51 lecture 7 - attention and scene perception. Attention any of the very large set of selective processes in the brain. To deal with the impossibility of handling all inputs at once, the nervous system has evolved mechanisms that are able to bias processing to a subset of things, places, ideas or moments in time. This relationship is however not linear eg. You"re very tired and take some caffeine, in the exam coffee sufficiently helps stay awake to do exam -> it increases arousal. But too much coffee, fingers shaking and can"t focus in exam arousal state is very high that you get distracted by everything and have a hard time focusing on everything else. More arousal is good, but too much is detrimental. Why do we need attention: bottlenecks: it is impossible to process everything at once.
