本研究的目的是调查高龄对自我报告的内部和外部记忆策略使用的影响，以及这种影响是否可以通过执行功能来预测。将194名年龄在21-80岁之间的被试分为三个年龄段(21-40岁、41-60岁、61-80岁)，完成了成人元记忆(MIA)问卷的两个策略量表、区分内部和外部日常记忆策略的使用，以及三个执行功能测试。结果表明：(1)外部记忆策略的使用随着年龄的增长而增加，而内部记忆策略的使用随着年龄的增长而减少；(2)执行功能似乎只与内部策略有关，内部策略使用最多的参与者具有最高的执行水平；(3)执行功能在内部策略使用的年龄相关变量中占有相当大的比例。这些发现表明，老年人优先使用外部记忆策略来应对因年龄增长而造成的日常记忆障碍。他们还支持这样一种观点，即认知老化的执行假说可以解释与年龄相关的内部记忆策略执行能力的下降。这一结果与客观实验室记忆策略测量的结果相一致，从而支持了自报记忆策略问卷的有效性。(C)2010爱思唯尔B.V.保留所有权利。
The aim of this study was to investigate the effect of advanced age on self-reported internal and external memory strategy uses, and whether this effect can be predicted by executive functioning. A sample of 194 participants aged 21 to 80 divided into three age groups (21-40, 41-60, 61-80) completed the two strategy scales of the Metamemory in Adulthood (MIA) questionnaire, differentiating between internal and external everyday memory strategy uses, and three tests of executive functioning. The results showed that: (I) the use of external memory strategies increased with age, whereas use of internal memory strategy decreased; (2) executive functioning appeared to be related only to internal strategies, the participants who reported the greatest use of internal strategies having the highest executive level; and (3) executive functioning accounted for a sizeable proportion of the age-related variance in internal strategy use. These findings suggest that older adults preferentially use external memory strategies to cope with everyday memory impairment due to aging. They also support the view that the age-related decrease in the implementation of internal memory strategies can be explained by the executive hypothesis of cognitive aging. This result parallels those observed using objective laboratory memory strategy measures and then supports the validity of self-reported memory strategy questionnaire. (C) 2010 Elsevier B.V.
