The present study used a cross-lagged panel design with longitudinal data to test if there is a reciprocal relationship between cognitive control beliefs and cognition (e.g., executive functioning and episodic memory) over 10 years, whether frequency of engaging in stimulating cognitive activities mediated this relationship, and if these relationships varied by age.
Data were collected as part of the second (M2, 2004-2005) and third (M3, 2013-2014) waves of the Midlife in the United States Study. The analysis sample included 2,532 participants with all variables at M2 and M3. Participants' ages ranged from 33 to 83 (M = 54.92, standard deviation = 11.13) at M2.
There was a reciprocal relationship between cognitive control beliefs and executive functioning. Higher executive functioning was related to greater maintenance of cognitive control beliefs for older, not younger, adults. Higher cognitive control beliefs were related to less decline in executive functioning. Though cognitive control beliefs predicted 10-year changes in episodic memory, the inverse relationship was not supported. Frequency of engaging in stimulating cognitive activities mediated the relationship between executive functioning and 10-year changes in cognitive control beliefs, but not cognitive control beliefs and 10-year changes in cognition.
Cognitive control beliefs are a promising mechanism to help protect against age-related declines in both executive functioning and episodic memory. Moreover, executive functioning also affects cognitive control beliefs. Specifically, those with higher executive functioning engage more frequently in stimulating cognitive activities, which helps maintain higher cognitive control beliefs.
本研究采用横断时间序列设计和纵向数据,以检验认知控制信念与认知(如执行功能和情景记忆)之间在 10 年内是否存在相互关系,是否经常参与刺激认知活动会影响这种关系,以及这些关系是否因年龄而异。
数据是作为美国中年研究第二(M2,2004-2005 年)和第三(M3,2013-2014 年)波次的一部分收集的。分析样本包括 2532 名在 M2 和 M3 时具有所有变量的参与者。参与者的年龄范围从 33 岁到 83 岁(M=54.92,标准差=11.13)。
认知控制信念与执行功能之间存在相互关系。较高的执行功能与年龄较大的成年人(而非年龄较小的成年人)认知控制信念的维持有关。较高的认知控制信念与执行功能的衰退减少有关。虽然认知控制信念预测了情景记忆的 10 年变化,但反向关系并未得到支持。刺激认知活动的频率调节了执行功能与认知控制信念 10 年变化之间的关系,但调节不了认知控制信念与认知 10 年变化之间的关系。
认知控制信念是一种有前途的机制,可以帮助预防执行功能和情景记忆随年龄增长而下降。此外,执行功能也会影响认知控制信念。具体来说,执行功能较高的人更频繁地参与刺激认知活动,这有助于维持较高的认知控制信念。
