Erectile responses among heterosexual child molesters, father-daughter incest offenders, and matched non-offenders: Five distinct age preference profiles.

Abstract

Erectile responses to pictures of nude females ranging in age from 3-24 years were studied in a group of 21 incest offenders, 40 non-familial child molesters, and a group of 22 non-offender subjects approximately matched on socioeconomic status, intelligence, and age. Profiles of erectile responses, plotting percent of full erection over age of target stimulus, were drawn for each individual subject. These profiles were sorted reliably by judges, and later by computer, into five distinct profile shapes reflecting:(1) a failure to discriminate among the stimuli; or a clear preference for either (2) adults, (3) adults and teens, (4) children, or (5) children and adults. Non-offenders primarily showed 'adult' profiles, while incest offenders displayed either a non-discriminating profile or an 'adult' preference pattern. The non-familial child molester group was heterogeneous in that members of this group were distributed among the five profile shapes. Offenders who displayed a 'child' profile reported a greater number of victims and were found to have used a greater degree of force in the commission of their most recent offence compared with other offenders. Further, offenders whose profiles were classified in the 'child' profile group were lower in socioeconomic status than offenders in the adult profile category.

Gaze patterns to child figures reflect deviant sexual preference in child sex offenders—a first glance

“…Phallometric studies commonly report that CSOs also demonstrate arousal to adult stimuli (Barbaree & Marshall, 1989;Freund, Watson, & Dickey, 1991;Harris, Rice, Quinsey, Chapin, & Earls, 1992;Lykins et al, 2010). Likewise, in this study the offenders showed a visual sexual assessment-related process to the mature adult (20-and 40-year-old figures), similar to that shown by the controls.…”

“…The non-offenders were expected to only demonstrate this pattern when viewing figures of mature adults. In line with phallometric studies, we did not expect to find any difference in the gaze behaviour between CSO and non-offenders when viewing adult stimuli (e.g., Barbaree & Marshall, 1989).…”

Changes in Scholarly Influence in Major American Criminology and Criminal Justice Journals between 1986 and 2000

“…William L. Marshall was the most-cited scholar in 1991-1995. His most-cited works then were "The Long-Term Evaluation of a Behavioral Treatment Program for Child Molesters" (Marshall and Barbaree 1988) and "Erectile Responses among Heterosexual Child Molesters, FatherDaughter Incest Offenders and Matched Nonoffenders" (Barbaree and Marshall 1989). However, his large number of citations was mainly a function of his large number of different works cited, which may be related to the fact that in 1991-1995 CJB published a number of articles focusing on sex offenders.…”

Sexual Deviation: Paraphilias

“…Some incest offenders respond most to adult females, which has led some authors (e.g., Quinsey, 1977) to speculate about nonsexual motives in incest. Barbaree and Marshall (1989) discovered five separate sexual preference profiles among child molesters. Two profiles were indicative of pedophilic arousal, one suggested a normal adult heterosexual orientation, one revealed a preference for adolescents, and the last involved indiscriminate arousal.…”
