The neurodevelopmental theory of pedohebephilia states that sexual interests in children arise from early neurodevelopmental perturbations, as, for example, evidenced by increased non-right-handedness, more childhood head injuries, and reduced intelligence and height. As corroborating evidence largely rests on samples of convicted men, we conducted online surveys among German-speaking (Study 1, N = 199) and English-speaking men (Study 2, N = 632), specifically targeting community members with pedohebephilic or teleiophilic interests. Although we detected theoretically meaningful sexual interest patterns in an embedded viewing time task, we could not detect expected neurodevelopmental differences between teleiophilic and pedohebephilic men in either of the two studies. Strikingly, pedohebephilic men who reported convictions for sexual offenses emerged as shorter and less intelligent than pedohebephilic men without convictions in Study 2. While elucidating possible third variable confounds, results have to be interpreted cautiously because of the methodological problems inherent to non-matched case control designs.
恋童癖和恋少年癖的神经发育理论指出，对儿童的性兴趣源于早期神经发育障碍，例如，惯用手为非右手、更多的儿童期头部受伤、以及智力和身高降低。由于佐证证据主要基于被定罪的男性样本，我们在德语人群中（研究 1，N=199）和英语人群中（研究 2，N=632）进行了在线调查，专门针对有恋童癖或恋少年癖好的社区成员。尽管我们在一项嵌入式观看时间任务中检测到了理论上有意义的性兴趣模式，但在这两项研究中，我们都未能检测到恋少年癖男性与恋童癖男性之间预期的神经发育差异。引人注目的是，在研究 2 中，报告有性犯罪定罪的恋童癖男性比没有定罪的恋童癖男性更矮、智力更低。虽然阐明了可能的第三方变量混杂因素，但由于非匹配病例对照设计固有的方法学问题，结果必须谨慎解释。
