Auditory evoked potentials were recorded in healthy medical students who were grouped according to whether they obtained a high or low score on an Object Sorting Test (OST), on which schizophrenics also obtain high scores. High-OST scoring male students compared to Low-OST scoring male students showed reduced P200 latency. This finding was replicated in a second study of medical students. The authors believe these results support the hypothesis that schizophrenic thought disorder and an equivalent loosening of thinking in nonschizophrenic populations (allusive thinking) have a neurophysiological basis in common, namely a relative weakness of inhibition operating on cortical and subcortical structures.
对健康医学生进行听觉诱发电位记录，这些学生根据在物体分类测试（OST）中得分高低分组，精神分裂症患者在该测试中也会获得高分。与低分OST的男学生相比，高分OST的男学生P200潜伏期缩短。这一发现于对医学生的第二项研究中得到重复。作者认为，这些结果支持以下假设：精神分裂症的思维障碍以及非精神分裂症人群中类似的思维松散（牵连观念性思维）具有共同的神经生理基础，即在皮层和皮层下结构上起作用的抑制相对减弱。
