Math. Psychol. 55, No. 5, 365-367 (2011).} \itemab Summary: It is shown that the symmetry of the receiver operating characteristic curve implies that the Kullback -- Leibler divergences between the signal and noise populations are equal when the arguments are interchanged. \itemrv{~} \itemcc{} \itemut{ROC; symmetry; Kullback-Leibler divergence} \itemli{doi:10.1016/j.jmp.2011.06.003} \end
