Document Summary
Nepalese required about 15 20 volts more than westerners b4 saying stim was painful. Consistent w/ hyp that nepalese have a higher threshold for pain perception. Hyp data based on clark & clark. Actual computational formulas: sensitivity d" = z (hit rate) z (false alarm rate, bias. Beta = ordinate (hit rate) / ordinate (false alarm rate) Quick and dirty methods: sensitivity subtract false alarm rate from the hit rate. If h > fa, the subj has some sensitivity to the detection task. If h = fa, the subject has no sensitivity to the detection task. If h < fa, smack the subj (this shouldn"t happen: bias compare the average percentages of y and n resp. Although both groups had a liberal bias, the westerners were more likely to respond that stim were painful compared to the nepalese. However, both groups were equally sensitive to pain; null hyp not rejected.
