It has been suggested that the memory complaints of patients who are not impaired on formal memory tests may reflect accelerated forgetting. We examined this hypothesis by comparing the 1-week delayed recall and recognition test performance of outpatients who were referred for neuropsychological assessment and who had normal memory performance during standard memory assessment with that of a non-patient control group. Both groups performed equally in verbal learning and delayed recall. However, after 1 week, the patients performed worse than controls on both recall and recognition tests. Although subjective memory ability predicted short-term memory function in patients, it did not predict long-term delayed forgetting rates in either the patients or controls. Thus, long-term delayed recall and recognition intervals provided no additional value to explain poor subjective memory ability in the absence of objective memory deficits.
有人提出，在正式记忆测试中未受损的患者的记忆主诉可能反映出加速遗忘。我们通过比较被转介进行神经心理学评估且在标准记忆评估中记忆表现正常的门诊患者与非患者对照组的1周延迟回忆和识别测试表现，来检验这一假设。两组在言语学习和延迟回忆方面表现相当。然而，1周后，患者在回忆和识别测试中的表现均比对照组差。尽管主观记忆能力可预测患者的短期记忆功能，但它既不能预测患者也不能预测对照组的长期延迟遗忘率。因此，在没有客观记忆缺陷的情况下，长期延迟回忆和识别间隔对于解释主观记忆能力差并无额外价值。
