The authors hypothesized that schizophrenic communication disturbances reflect specific cognitive deficits in the areas of working memory and attention. They examined the cognitive correlates of communication disturbances, as measured by linguistic reference performance, in schizophrenic (n = 48), bipolar (n = 24), and nonpsychiatric control (n = 23) individuals. Reference performance ratings in the schizophrenic patients were associated with scores on tests of working memory and attention and were not related to performance on concept formation or verbal fluency tests. In contrast, in the bipolar and nonpsychiatric individuals, reference performance was associated with concept formation and verbal fluency test scores but was not related to performance on tests of working memory. Implications with respect to the processes underlying schizophrenic communication disturbances are discussed.
作者推测，精神分裂症患者的交流障碍反映了工作记忆和注意力方面的特定认知缺陷。他们研究了精神分裂症患者（n = 48）、双相情感障碍患者（n = 24）和非精神疾病对照者（n = 23）中，由语言指称表现所衡量的交流障碍的认知相关性。精神分裂症患者的指称表现评分与工作记忆和注意力测试的分数相关，而与概念形成或语言流畅性测试的表现无关。相比之下，双相情感障碍患者和非精神疾病对照者的指称表现与概念形成和语言流畅性测试分数相关，但与工作记忆测试的表现无关。文中讨论了精神分裂症交流障碍潜在过程的相关影响。
