The manner in which executive control functioning exerts its influence on functional tasks was investigated. Sixty older adults were administered neuropsychological tasks tapping into four domains of executive control function, including working memory, planning, fluency, and flexibility. A test of performance-based functional ability also was administered. Correlational analyses demonstrated that working memory was most strongly associated with performance-based functional ability; however, impairment in planning appeared to best predict performance-based functional decrement in simultaneous regression models. Results highlight the role of planning in the maintenance of functional ability, as measured by performance-based functional measures.
研究了执行控制功能对功能性任务施加影响的方式。对60名老年人进行了神经心理学任务测试，这些任务涉及执行控制功能的四个领域，包括工作记忆、计划、流畅性和灵活性。还进行了一项基于表现的功能能力测试。相关分析表明，工作记忆与基于表现的功能能力关联最为紧密；然而，在同时回归模型中，计划能力受损似乎最能预测基于表现的功能下降。结果突出了计划在维持基于表现的功能测量所衡量的功能能力方面的作用。
