Lg. Castonguay et al., SEXUAL PREFERENCE ASSESSMENT OF SEXUAL AGGRESSORS - PREDICTORS OF PENILE RESPONSE MAGNITUDE, Archives of sexual behavior, 22(4), 1993, pp. 325-334
A current method used to assess the sexual preference of sexual aggres
sors is the recording of their penile responses during the presentatio
n of erotic stimuli. This method is ineffective in subjects who do not
obtain sufficient penile responses. Whether variables related either
to the subjects or their crimes would correlate with the magnitude of
penile responses during sexual preference assessment was studied. The
penile responses of 92 subjects were recorded. Older and presentencing
subjects showed a lower maximum penile response magnitude than younge
r and sentenced subjects. Results are discussed as they relate to the
validity of physiological assessment of sexual preference.
