The California Verbal Learning Test (CVLT) is designed to quantify components of verbal learning, retention and retrieval. The present study used multiple regression analyses to correct for demographic characteristics on CVLT performance measures. There were 906 subjects, of whom 549 were Caucasians (61%) and 357 were African Americans (39%). Age, education, ethnicity, and gender were found to be significant predictors of performance on several CVLT indices, including Total Words Recalled, Trial 1, Trial 5, List B, Short Delay Free Recall (SDFR), and Long Delay Free Recall (LDFR). Demographically corrected T-scores were calculated for a base sample of 672 subjects and cross-validated on 234 separate subjects. Tables and regression equations are offered to convert raw scores into T-scores corrected for age, gender, education, and ethnicity. Demographically corrected Recognition Discriminability cutoff scores were calculated for age and education levels. In order to provide some indices of important memory processes, we also computed indices of retrieval, Short-Delay forgetting and Long-Delay forgetting and present normative information for them.
加利福尼亚言语学习测验（CVLT）旨在对言语学习、记忆保持和提取的各个成分进行量化。本研究使用多元回归分析来校正人口统计学特征对CVLT成绩指标的影响。共有906名受试者，其中549名是白种人（61%），357名是非洲裔美国人（39%）。年龄、教育程度、种族和性别被发现是几个CVLT指标成绩的显著预测因素，这些指标包括总回忆单词数、第1次测验、第5次测验、B表、短延迟自由回忆（SDFR）和长延迟自由回忆（LDFR）。为672名受试者的基础样本计算了经人口统计学校正的T分数，并在234名独立受试者上进行了交叉验证。提供了表格和回归方程，以将原始分数转换为经年龄、性别、教育程度和种族校正的T分数。计算了不同年龄和教育水平的经人口统计学校正的识别辨别力临界分数。为了提供一些重要记忆过程的指标，我们还计算了提取、短延迟遗忘和长延迟遗忘的指标，并给出了相应的常模信息。
