The objective of this study was to explore the exact nature, extent, and cognitive correlates of prospective memory deficits in mild cognitive impairment (MCI) by using the Ecological Test of Prospective Memory (TEMP). Twenty-five MCI participants and 25 healthy older adults (HOA) performed the TEMP, the Envelope Task, the Comprehensive Assessment of Prospective Memory (CAPM), and a neuropsychological test battery. Results showed that, during the TEMP, MCI participants had difficulty detecting the moment to perform the intentions in the time-based condition (prospective component) and retrieving the associated actions in the event- and time-based conditions (retrospective component). The prospective component of the event-based condition was correlated with retrospective memory, whereas the prospective component of the time-based condition was correlated with executive functions. Finally, the TEMP yielded good sensitivity and specificity for discriminating between MCI and HOA, contrary to the Envelope Task and the CAPM.
本研究旨在通过使用前瞻性记忆生态测试（TEMP）来探究轻度认知障碍（MCI）患者前瞻性记忆缺陷的本质、程度和认知相关性。25 名 MCI 参与者和 25 名健康老年人（HOA）完成了 TEMP、信封任务、前瞻性记忆综合评估（CAPM）和神经心理学测试。结果表明，在 TEMP 中，MCI 参与者在基于时间的条件（前瞻性成分）中难以检测到执行意图的时刻，并且在基于事件和基于时间的条件（回溯性成分）中难以检索相关动作。基于事件条件的前瞻性成分与回溯性记忆相关，而基于时间条件的前瞻性成分与执行功能相关。最后，与信封任务和 CAPM 相反，TEMP 在区分 MCI 和 HOA 方面具有良好的敏感性和特异性。
