This study shows that chronic, long-hospitalized schizophrenics perform (tested by the Famous Events Questionnaire) at a higher level on remote memory than they do on word list recall. A post hoc, matched-tasks check suggested that this finding was not due to differences in the discriminating power of the tasks. Relative to normals, patients showed no differential performance on the three time periods (1973/74, 1979/80, 1984) represented in the remote memory questionnaire, thus giving no evidence for an amnesic gradient. The findings are discussed in relation to amnesia and dementia hypotheses in chronic schizophrenia.
这项研究表明，慢性、长期住院的精神分裂症患者（通过著名事件问卷测试）在远期记忆方面的表现要高于他们在单词列表回忆方面的表现。事后进行的匹配任务检查表明，这一发现并非由于任务辨别力的差异所致。相对于正常人，患者在远期记忆问卷所代表的三个时间段（1973/74、1979/80、1984）上没有表现出差异，因此没有证据表明存在遗忘梯度。本文将结合慢性精神分裂症的遗忘和痴呆假说对这些发现进行讨论。
