Contingent negative variation as an indicator of sexual object preference.
The contingent negative variation (CNV) was recorded in the interval between paired visual exposures of male nudes, female nudes, and sexually "neutral" silhouettes. Groups of 12 male and 12 female subjects viewing 50 randomized presentations from each stinmulus category responded with averaged CNV amplitudes proportional to the predicted degree of sexual interest in the stimulus classes.
