The California Verbal Learning Test, Second Edition (CVLT-II) and the Virtual Environment Grocery Store (VEGS) use list learning and recognition tasks to assess episodic memory. This study aims to: (1) Replicate prior construct validity results among a new sample of young adults and healthy older adults; (2) Extend this work to a clinical sample of older adults with a neurocognitive diagnosis; (3) Compare CVLT-II and VEGS performance among these groups; and (4) Validate the independence of CVLT and VEGS episodic memory performance measures from executive functioning performance measures. Typically developing young adults ( = 53) and older adults ( = 85), as well as older adults with a neurocognitive diagnosis ( = 18), were administered the CVLT-II, VEGS, and D-KEFS CWIT. Results found that (1) the relationship of the VEGS and CVLT-II measures was highly correlated on all variables, (2) compared to the CVLT-II, participants (particularly older adults) recalled fewer items on the VEGS, and (3) the CVLT-II and VEGS were generally independent of D-KEFS CWIT. It appeared that the VEGS may be more difficult than the CVLT-II, possibly reflecting the word length effect. Performance may have also been impacted by the presence of everyday distractors in the virtual environment.
加利福尼亚言语学习测验第二版（CVLT-II）和虚拟环境杂货店任务（VEGS）使用列表学习和识别任务来评估情景记忆。本研究旨在：（1）在新的年轻成年人和健康老年人样本中复制先前的结构效度结果；（2）将这项工作扩展到患有神经认知障碍诊断的老年人临床样本；（3）比较这些组中CVLT-II和VEGS的表现；以及（4）验证CVLT和VEGS情景记忆表现测量相对于执行功能表现测量的独立性。对典型发育的年轻成年人（n = 53）、老年人（n = 85）以及患有神经认知障碍诊断的老年人（n = 18）进行了CVLT-II、VEGS和D-KEFS CWIT测试。结果发现：（1）VEGS和CVLT-II测量在所有变量上的关系高度相关；（2）与CVLT-II相比，参与者（尤其是老年人）在VEGS上回忆的项目较少；（3）CVLT-II和VEGS通常独立于D-KEFS CWIT。似乎VEGS可能比CVLT-II更难，这可能反映了词长效应。虚拟环境中日常干扰因素的存在也可能影响了表现。
