It has repeatedly been demonstrated that patients with dementia of the Alzheimer type (DAT) show an absence of the primacy effect when asked to recall a list of items. The results of the present study show that the absence of the primacy effect in DAT patients is related to list length but probably in a way that is qualitatively not specific since it follows the same pattern as in normal ageing. It is also demonstrated that DAT patients differ in learning style. It is suggested that this indicates a reduced capacity to maintain controlled processing.
反复有研究表明，患阿尔茨海默型痴呆症（DAT）的患者在被要求回忆一组物品时，表现出首因效应缺失。本研究结果表明，DAT患者首因效应的缺失与列表长度有关，但可能在性质上并非特定的，因为其遵循与正常衰老相同的模式。研究还表明，DAT患者在学习方式上存在差异。有人认为，这表明维持控制性加工的能力有所下降。
