Executive functioning (EF), which is considered to govern complex cognition, and verbal memory (VM) are constructs assumed to be related. However, it is not known the magnitude of the association between EF and VM, and how sociodemographic and psychological factors may affect this relationship, including in normal aging. In this study, we assessed different EF and VM parameters, via a battery of neurocognitive/psychological tests, and performed a Canonical Correlation Analysis (CCA) to explore the connection between these constructs, in a sample of middle-aged and older healthy individuals without cognitive impairment ( = 563, 50+ years of age). The analysis revealed a positive and moderate association between EF and VM independently of gender, age, education, global cognitive performance level, and mood. These results confirm that EF presents a significant association with VM performance.
执行功能（EF）被认为掌管复杂认知，言语记忆（VM）是假定与之相关的结构。然而，EF与VM之间关联的程度，以及社会人口统计学和心理因素如何影响这种关系（包括在正常衰老过程中）尚不清楚。在本研究中，我们通过一系列神经认知/心理测试评估了不同的EF和VM参数，并对一组无认知障碍的中年及老年健康个体（n = 563，年龄50岁及以上）进行了典型相关分析（CCA），以探索这些结构之间的联系。分析显示，EF与VM之间存在正向且适度的关联，且不受性别、年龄、教育程度、整体认知表现水平和情绪的影响。这些结果证实，EF与VM表现之间存在显著关联。
