Cantor, James M., Blanchard Ray, Christensen Bruce K., Dickey Robert, Klassen Philip E., Beckstead Lee A., et al.; 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. [...]
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.

The present study sought to validate the concept of hebephilia by examining the agreement between self-reported sexual interests and objectively recorded penile responses in the laboratory.
These results indicated that hebephilia exists as a discriminable erotic age-preference.
The authors recommend various ways in which the DSM might be altered to accommodate the present findings. One possibility would be to replace the diagnosis of Pedophilia with Pedo-hebephilia [...].
