Answer 6

All of these areas are used for language

Question 7

Slide 7: Match model of cortical function with the theory:(1) Associative processing(2) Holistic processing(3) Localized function(A) Lesion ==> loose that function(B) Lesion ==> don’t lose function entirely; lose it partially because other parts of the brain network help pick-up slack and retain that function(C) Lesion ==> can significantly impair function but it depends particularly on where the lesion occurred

(1) = (C)(2) = (B)(3) = (A)
