A sample of 404 adult men underwent assessment following illegal or clinically significant sexual behaviors or interests. Patients' assessments included: administration of a modified version of the Edinburgh Handedness Inventory; recording of patients' phallometric (penile) responses to erotic stimuli depicting adults, pubescent children, and prepubescent children of both sexes; and a tabulation of the numbers of patients' victims, ages 0-11, 12-14, 15-16, and 17 and older, of both sexes. In Study 1, patients' right-handedness scores correlated negatively with their phallometric responses to stimuli depicting prepubescent children and positively with stimuli depicting adults, replicating the pattern described in a previous report (Cantor et al., 2004). Unlike the previous study, however, patients' handedness scores did not significantly correlate with their numbers of prepubescent victims. To explore this discrepancy, Study 2 combined the patients from this replication sample with those in the previously reported sample, categorizing them by the sex and age group of greatest erotic interest to them. The odds of non-right-handedness in men offending predominantly against prepubescent children were approximately two-fold higher than that in men offending predominantly against adults and three-fold higher after eliminating those men with intrafamilial (i.e., incest) offenses. Handedness differences between men erotically interested in males versus females were not statistically significant. These results indicate that the rates of non-right-handedness in pedophilia are much larger than previously suggested and are comparable to the rates observed in pervasive developmental disorders, such as autism, suggesting a neurological component to the development of pedophilia and hebephilia.
404名成年男性样本在出现非法或具有临床意义的性行为或兴趣后接受了评估。患者的评估包括：进行爱丁堡利手量表的修订版测试；记录患者对描绘成年男女、青春期前儿童和青春期儿童的色情刺激的阴茎反应；以及统计患者针对0至11岁、12至14岁、15至16岁和17岁及以上男女受害者的数量。在研究1中，患者的右利手得分与他们对描绘青春期前儿童的刺激的阴茎反应呈负相关，与描绘成年人的刺激呈正相关，这与之前一份报告（坎托等人，2004年）中描述的模式一致。然而，与之前的研究不同，患者的利手得分与他们青春期前受害者的数量没有显著相关性。为了探究这种差异，研究2将这个重复样本中的患者与之前报告样本中的患者合并，根据他们最大色情兴趣的性别和年龄组对他们进行分类。主要侵犯青春期前儿童的男性中，非右利手的几率比主要侵犯成年人的男性高出约两倍，在排除那些有家族内（即乱伦）犯罪行为的男性后，高出三倍。对男性和女性有性兴趣的男性之间的利手差异没有统计学意义。这些结果表明，恋童癖中非右利手的发生率比之前认为的要高得多，与自闭症等广泛性发育障碍中观察到的发生率相当，这表明恋童癖和青春期恋的发展存在神经学成分。
