PSY290H1 Lecture Notes - Lecture 1: Lobotomy, Parietal Lobe, Brainstem
Document Summary
B/w subjects design: having 2 groups and comparing them w/in subjects design: taking an individual and putting them through different treatments. Any diff in dv is supposed to be due to the iv if an experiment is performed correctly. Jose delgado example: he inserted stimulator into the brain of a bull just to activate that part of the brain with a remote control. When he pushed the button the bull stopped. He interpreted it as he tapped into the anger center of the bull. But in reality it was planted in a motor region. The bull is going straight, but when the button is pushed it stops and turns right. Egas moniz example for pf lobotomy: becky (chimpanzee) gets upset when she made errors during a food rewarded tasks (bc she didn"t get food) After bilateral lesions to pf lobes, she no longer became upset. It"s difficult to conclude what"s happening with only this info.
