对20例男性慢性精神分裂症患者、12例慢性精神分裂症患者和20例正常对照者进行了40克（轻）和400克（重）标准体重的上限差异测试。体重歧视阈值被发现显着升高作为一个功能的严重程度的病理精神分裂症组，也在较轻的重量强度。两组精神分裂症患者的体重都比正常人有明显的改善。轻度精神分裂症患者在高强度下与正常人无显著性差异。这些结果支持精神分裂症患者本体感受敏锐度缺陷的假设，并表明这种缺陷是本体感受反馈不足的结果。（PsycInfo数据库记录（c）2022阿帕，保留所有权利）
20 male chronic schizophrenics, 12 chronic disturbed schizophrenics, and 20 normal controls were tested for upper difference limens from both a 40-gm (light) and 400-gm (heavy) standard weight. Weight discrimination thresholds were found to be significantly elevated as a function of severity of pathology in the schizophrenic groups and also at the lighter weight intensity. Both groups of schizophrenics showed significantly greater improvement than normals with the heavy weights. The less disturbed chronic schizophrenics were not significantly different from normals at the heavy intensity. The results support the hypothesis of a schizophrenic deficit in proprioceptive acuity and suggest that this deficit is the result of insufficient proprioceptive feedback.(PsycInfo Database Record (c) 2022 APA, all rights reserved)
