本研究考察了第二代和第三代日裔美国成年人（JA）的认知测试表现，这是一个相对同质的亚裔美国人亚群。65名JA和65名非西班牙裔白人（NHW）成年人，年龄在45 ~ 91岁之间，进行了波士顿命名测试（BNT）、字母流畅性测试、语义流畅性测试、加州语言学习测试（CVLT）、简短视觉空间记忆测试（BVMT-R）和轨迹制作测试。在美国，文化适应水平、教育成就质量和世代地位也被收集。在进行的测试中，两组之间的得分没有显著差异。然而，JA组和NHW组在一些测试表现和人口变量之间的关联模式上有所不同。JA成人在BNT、CVLT和BVMT-R上表现出较强的年龄得分关系。此外，即使在控制了CVLT和Trail Making Test的基本人口统计变量后，第二代JA成人的表现也低于第三代成人。另一方面，一旦考虑到人口变量，文化适应就不能解释得分差异。我们的研究结果表明，在不同认知需求的任务中，考虑民族独特的历史和特征，以及老龄化过程和文化的相互作用是重要的。
This study examined cognitive test performance of second-and third-generation Japanese American (JA) adults, a relatively homogeneous Asian American subgroup. Sixty-five JA and 65 non-Hispanic White (NHW) adults, ages between 45 and 91, were administered the Boston Naming Test-2 (BNT), Letter Fluency Test, Semantic Fluency Test, California Verbal Learning Test (CVLT), Brief Visuospatial Memory Test-Revised (BVMT-R), and Trail Making Test. Levels of acculturation, quality of educational attainment, and generation status in the United States, were also collected. There were no significant differences in the scores between the two groups on the tests administered. JA and NHW groups, however, differed in the patterns of the associations between some of the test performance and demographic variables. JA adults showed a stronger age-score relationship on BNT, CVLT, and the BVMT-R. Furthermore, second-generation JA adults performed lower than the third-generation adults even after controlling for basic demographic variables on CVLT and Trail Making Test. Acculturation on the other hand did not explain score differences once demographic variables were considered. Our results suggest the importance of considering unique history and characteristics of ethnic groups, and interactions of the aging process and culture on tasks with different cognitive demands.
