Intelligence, Memory, and Handedness in Pedophilia

A sample of 473 male patients with pedophilia (assessed by the patients' sexual history and penile response in the laboratory to standardized, erotic stimuli) or other problematic sexual interests or behaviors received brief neuropsychological assessments. Neuropsychological measures included a short form of the Wechsler Adult Intelligence Scale-Revised ( D. Wechsler, 1981 ), the Hopkins Verbal Learning Test-Revised ( R. H. B. Benedict, D. Schretlen, L. Groninger, & J. Brandt, 1998 ), the Brief Visuospatial Memory Test-Revised ( R. H. B. Benedict, 1997 ), and the Edinburgh Handedness Inventory ( S. M. Williams, 1986 ). Pedophilia showed significant negative correlations with IQ and immediate and delayed recall memory. Pedophilia was also related to non-right-handedness even after covarying age and IQ. These results suggest that pedophilia is linked to early neurodevelopmental perturbations.
