Relationships between performance on the California Verbal Learning Test (CVLT) and executive abilities were examined. In a sample of 115 neurological cases principal components factor analysis produced five theoretically and clinically meaningful CVLT factors. The five CVLT factors reflected general verbal learning (CVLT1), response discrimination (CVLT2), a proactive interference effect or "working memory" (CVLT3), serial learning strategy (CVLT4), and a retroactive interference effect (CVLT5). Canonical correlation between executive function measures and the five CVLT factor scores yielded one significant canonical variable accounting for 29 percent of the variance in the data. Two CVLT factors (CVLT1 and CVLT3), the Trail Making Test Part B, and Digit Span were significantly correlated with the canonical variate. Higher levels of memory performance were associated with better attention and mental tracking. Based on the present findings, attentional aspects of executive abilities appear to play a role in learning and working memory. Other aspects of executive abilities (abstraction, problem-solving, planning) appear to have minimal relationships with memory processes.
研究了加利福尼亚言语学习测验（CVLT）成绩与执行能力之间的关系。在115例神经病例样本中，主成分因素分析产生了五个在理论和临床上有意义的CVLT因素。这五个CVLT因素反映了一般言语学习（CVLT1）、反应辨别（CVLT2）、前摄干扰效应或“工作记忆”（CVLT3）、系列学习策略（CVLT4）和倒摄干扰效应（CVLT5）。执行功能测量与五个CVLT因素得分之间的典型相关性产生了一个显著的典型变量，该变量解释了数据中29%的方差。两个CVLT因素（CVLT1和CVLT3）、连线测验B部分和数字广度与典型变量显著相关。较高水平的记忆表现与更好的注意力和心理追踪能力相关。基于目前的研究结果，执行能力的注意力方面似乎在学习和工作记忆中发挥作用。执行能力的其他方面（抽象、解决问题、规划）似乎与记忆过程关系最小。
