Michael Cole and His Colleagues Studied the Memory Performance in Tribal

Michael Cole and his colleagues studied the memory performance in tribal children of rural Liberia on a free recall task of items in four distinct categories. They found:

B) a comparable performance to that of U.S. school children of the same age.
C) little improvement in performance of nonschooled children after the age of 10.
D) no difference in memory performance compared to that of children in industrialized Liberian societies.
