独特性启发式是一种反应模式，参与者期望记住经验的生动细节，并在这种元认知期望的基础上做出识别决定。作者研究了独特性启发式是否可以用于减少阿尔茨海默病(AD)患者在重复-滞后范式中的错误识别。阿尔茨海默病患者能够使用独特性启发式--尽管不是有选择性的--因此他们表现出真假识别的减少。作者认为，阿尔茨海默病患者可以基于与使用独特性启发式相关的元认知期望来进行决策策略，但患者的情景记忆障碍限制了这种策略的范围和有效性。
The distinctiveness heuristic is a response mode in which participants expect to remember vivid details of an experience and make recognition decisions on the basis of this metacognitive expectation. The authors examined whether the distinctiveness heuristic could be engaged to reduce false recognition in a repetition-lag paradigm in patients with Alzheimer's disease (AD). Patients with AD were able to use the distinctiveness heuristic-though not selectively-and thus they showed reduction of both true and false recognition. The authors suggest that patients with AD can engage in decision strategies on the basis of the metacognitive expectation associated with use of the distinctiveness heuristic, but the patients' episodic memory impairment limits both the scope and effectiveness of such strategies.
