PSYC 108 Lecture Notes - Lecture 5: Voxel, Dependent And Independent Variables
Document Summary
Find two patients with damage to different regions: group 1 is impaired at task a, but not b, group 2 is impaired at task b, but not a, broca"s and wernicke"s. Single case approach: particular brain region damaged, example: hm, problems with single cases, hard to generalize, group study. Large variability between brains: the lesions aren"t exactly the same. So you need to group by gross area of damage: statistical comparison. Independent variable: those with and without damage, dependent variable, t-test at each voxel on behavioral score = what"s being measured.
