PSYC 3030 Study Guide - Speech Segmentation, Parietal Lobe, Tennis Ball
Document Summary
Shadow detectors (escape predators) and movement detectors (eat) for frogs. Speech segmentation: you are able to use top down word knowledge to segment speech and insert mental pauses in words where there aren"t any pauses. We have a lot of top down knowledge when we look at faces. When we take away the top down knowledge we fail to notice some things (the upside down faces/thatcher faces) Tulving studied the duration (bottom-up) in which the word was visible and the context (top- down) in which the word was located. He would flash the words to see what words were more important in the context. As the word was played for longer durations, people could see it better. Also, the more words that were available at first, the better people were at getting the word. This experiment demonstrates that both processes have large effects. Reicher asked participants to not identify words, but to identify letters that were displayed during varied durations.
