本研究探讨了语义组织在精神分裂症患者言语记忆效率中的作用。患者和健康对照组被管理的自由回忆任务，涉及1 nonsemantic ally有组织的列表，1列表有组织的语义类别与典型的实例和1列表有组织的语义类别与非典型的实例。在患者中观察到语义组织减少。回归分析表明，在非典型组织列表的语义聚类得分作出了显着的贡献，患者的回忆性能。当控制语义聚类时，诊断对自由回忆的影响显著。这些结果表明，语义组织的深度是影响精神分裂症患者言语记忆成绩的一个重要因素。然而，语义组织缺陷并不能解释整个回忆障碍。
The role of semantic organization in verbal memory efficiency in schizophrenia was investigated. Patients and healthy controls were administered a free-recall task involving 1 nonsemantic ally organizable list, 1 list organizable in semantic categories with typical instances and 1 list organizable in semantic categories with atypical instances. Reduced semantic organization was observed in patients. Regression analyses showed that the semantic clustering score in the atypical organizable list made a significant contribution to recall performance in patients. When semantic clustering was controlled, the effect of diagnosis on free recall was significant. These results suggest that depth of semantic organization is a crucial factor of verbal memory performance in schizophrenia. However, semantic organizational deficit does not account for the whole recall impairment.
