日常任务（DOT），一个自然主义的任务，需要在现实世界中的多任务处理，被用来检查轻度认知障碍（MCI）个体的日常功能。方法38名MCI参与者和38名认知健康的老年人控制优先，组织，启动，并完成了一些子任务，在校园公寓准备一天（例如，确定和收集公共汽车的变化，带一本杂志）。参与者还完成了测试评估认知结构的重要多任务（即，回顾性记忆，前瞻性记忆，规划）。ResultsAs相比，控制，MCI组需要更多的时间来完成DOT和表现出较差的任务准确性，执行更多的子任务不完全和不准确。尽管DOT任务的准确性较差，MCI组和对照组以类似的方式接近完成DOT。对于MCI组，回顾性记忆是不完整和不准确的子任务数量的唯一预测因子，而前瞻性记忆是DOT排序的唯一预测因子。DOT的措施，但不是认知测试，是预测知识渊博的线人报告的日常functions.ConclusionsThese研究结果表明，难以记住和跟踪多个目标和子目标可能会导致个人MCI在复杂的日常情况下表现较差。（PsycInfo数据库记录（c）2020阿帕，保留所有权利）
ObjectiveThe day-out task (DOT), a naturalistic task that requires multitasking in a real-world setting, was used to examine everyday functioning in individuals with mild cognitive impairment (MCI).MethodThirty-eight participants with MCI and 38 cognitively healthy older adult controls prioritized, organized, initiated, and completed a number of subtasks in a campus apartment to prepare for a day out (eg, determine and gather change for bus, bring a magazine). Participants also completed tests assessing cognitive constructs important in multitasking (ie, retrospective memory, prospective memory, planning).ResultsAs compared with controls, the MCI group required more time to complete the DOT and demonstrated poorer task accuracy, performing more subtasks incompletely and inaccurately. Despite poorer DOT task accuracy, the MCI and control groups approached completion of the DOT in a similar manner. For the MCI group, retrospective memory was a unique predictor of the number of subtasks left incomplete and inaccurate, while prospective memory was a unique predictor of DOT sequencing. The DOT measures, but not the cognitive tests, were predictive of knowledgeable informant report of everyday functioning.ConclusionsThese findings suggest that difficulty remembering and keeping track of multiple goals and subgoals may contribute to the poorer performance of individuals with MCI in complex everyday situations.(PsycInfo Database Record (c) 2020 APA, all rights reserved)
