Mainpage  >  Bio



Dr. James Cantor is a clinical and research psychologist studying human sexuality and sexual problems. He has been applying MRI and other techniques to examine the role of the brain in pedophilia and hebephilia (the sexual preference for prepubescent and pubescent aged children) for over ten years.


James Cantor is the Head of Research in the Law and Mental Health Program of the Centre for Addiction and Mental Health and is called up to consult internationally on the scientific study of paraphilias and sexual offenses.  He is currently the Editor-in-Chief of Sexual Abuse: A Journal of Research and Treatment (SAJRT), the official journal of the Association for the Treatment of Sexual Abusers.  Dr. Cantor is an Associate Professor of the University of Toronto Faculty of Medicine.


Dr. Cantor’s team has found that men with pedophilia or hebephilia differ from typical men in multiple ways: On brain scans, pedophilic and hebephilic men show significantly less white matter in large brain regions (called the superior occipitofrontal fasciculus and the right arcuate fasciculus).  On other testing, pedophilic and hebephilic men show significantly lower mean IQs, a three-fold elevation in the odds of being non-right-handed, a greater probability of having suffered head injuries during childhood, and a deficit in physical height that is double the effect that emerges from when mothers smoke cigarettes during pregnancy. Their research results have been reported in Psychological Bulletin, the Journal of Psychiatric Research, the Archives of Sexual Behavior, and SAJRT.


Dr. Cantor’s clinical activities focus on the assessment and treatment of persons dealing with illegal or clinically significant sexual behaviours or interests, including pedophilia and hypersexuality. 


Manuscripts to be considered for publication in SAJRT should be submitted electronically by uploading through the journal’s submission portal, available at http://mc.manuscriptcentral.com/sajrt.  Dr. Cantor also serves on the editorial boards of the Archives of Sexual Behavior and The Journal of Sex Research.  Dr. Cantor is a member of the International Academy of Sex Research, the Society for the Scientific Study of Sexuality, and the Society for Neuroscience.
