本文研究了精神分裂症患者的工作记忆及其对策略记忆测验成绩的影响。患者（n= 18）和对照参与者（n= 15），所有男性，接受即时记忆（向前数字跨度），工作记忆（听力，计算和向后数字跨度），长期战略（自由回忆，时间顺序和自我排序指向）和非战略（识别）记忆的测试。精神分裂症患者在所有测试中表现更差。教育、语言智力和即时记忆能力不能解释精神分裂症患者工作记忆的缺陷。工作记忆容量的减少可以解释策略记忆的组间差异，但不能解释再认记忆的组间差异。工作记忆障碍可能是精神分裂症认知功能障碍的核心，与这种疾病相关的额叶功能障碍的假设是一致的。额外的内侧颞叶功能障碍可能是识别记忆缺陷的原因。（PsycINFO数据库记录（c）2016阿帕，保留所有权利）
Working memory and its contribution to performance on strategic memory tests in schizophrenia were studied. Patients (n= 18) and control participants (n= 15), all men, received tests of immediate memory (forward digit span), working memory (listening, computation, and backward digit span), and long-term strategic (free recall, temporal order, and self-ordered pointing) and nonstrategic (recognition) memory. Schizophrenia patients performed worse on all tests. Education, verbal intelligence, and immediate memory capacity did not account for deficits in working memory in schizophrenia patients. Reduced working memory capacity accounted for group differences in strategic memory but not in recognition memory. Working memory impairment may be central to the profile of impaired cognitive performance in schizophrenia and is consistent with hypothesized frontal lobe dysfunction associated with this disease. Additional medial-temporal dysfunction may account for the recognition memory deficit.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
