Manic (N = 18) and schizophrenic (N = 23) patients were evaluated with a linguistic assessment of reference failures and were tested with a digit span distraction task. It was found that, although manics and schizophrenics did not differ in their distraction performance, there were differential relationships between task performance and reference performance across the two subject samples. Both distraction and nondistraction performances were related equally to discourse failures in manics while distraction performance was a much better predictor of discourse failure than nondistraction performance in the schizophrenic sample. The fact that susceptibility to the effects of distraction seemed to be an important and specific predictor of discourse failures in schizophrenia is discussed in terms of recent developments in research and theory regarding schizophrenic speech disorders.
对18名躁狂症患者和23名精神分裂症患者进行了指代失误的语言评估，并通过数字广度分心任务进行了测试。结果发现，虽然躁狂症患者和精神分裂症患者在分心表现上没有差异，但在这两个受试者样本中，任务表现与指代表现之间存在不同的关系。在躁狂症患者中，分心和不分心表现与语篇失误的相关性相同，而在精神分裂症样本中，分心表现比不分心表现更能预测语篇失误。根据近期关于精神分裂症言语障碍的研究和理论进展，讨论了分心影响易感性似乎是精神分裂症语篇失误的一个重要且特定预测因素这一事实。
