Three experiments using variations of the Subject Performed Task (SPT) paradigm examined whether structuring the learning and retrieval environment would improve learning in individuals with mild to moderate dementia of the Alzheimer type (DAT). Experiment 1 examined the role of enactment at encoding and retrieval, and found that with appropriate retrieval support DAT volunteers do benefit from enactment at encoding. Experiment 2 showed that recall was further enhanced when the list of SPTs formed a cohesive, goal-directed sequence of actions. In Experiment 3, DAT subjects acquired a more complex action-based sequence and maintained it accurately over a short period of time. It is concluded that the provision of contextual support at encoding and at retrieval can enhance residual memory in individuals with DAT.
三项采用主体执行任务（SPT）范式变体的实验，研究了构建学习和检索环境是否会改善轻度至中度阿尔茨海默病型痴呆（DAT）患者的学习情况。实验1考察了在编码和检索时进行动作表现的作用，发现有适当的检索支持时，DAT志愿者确实能从编码时的动作表现中受益。实验2表明，当SPT列表形成一个连贯的、目标导向的动作序列时，回忆会进一步增强。在实验3中，DAT受试者习得一个更复杂的基于动作的序列，并在短时间内准确保持。研究得出结论，在编码和检索时提供情境支持可以增强DAT患者的残余记忆。
