Forty-two undergraduates were classified into High-High Amplitude Group, High-Low Amplitude Group, and Low-Low Amplitude Group, according to the change patterns of their GSR waves. They were asked to reiterate classical Chinese poems and to take "subtests" of Raven's Progressive Matrices. Their lowest absolute skin resistance and scores on Raven's "subtests" were recorded before and after their performance being observed by their classmates.
