Abstract

We evaluated age effects in the Wechsler Abbreviated Scale of Intelligence-Second Edition (WASI-II) standardization sample. This extends work completed using previous editions of the Wechsler Adult Intelligence Scales. Of the four subtests, Vocabulary (VC) and Similarities (SI) were most resistant to aging. VC showed minimal variation regardless of age; SI peaked at 30 to 54 years followed by a decline. Block Design (BD) and Matrix Reasoning (MR) showed substantial drops from the younger to older groups. BD peaked at 17 to 44 years and then declined; MR peaked at 20 to 29 years and then consistently deteriorated. The WASI-II Verbal Comprehension Index peak at 30 to 44 years was followed by a maximum drop at 85 to 90 years. The Perceptual Reasoning Index peaked at 20 to 29 years, with a marked decline by 65 to 69 years. The Full Scale IQ was average until age 65 years followed by a decline. Minor changes in points of peak performance and subsequent decline were seen as a function of Full Scale IQ level. Results were consistent with crystallized and fluid intelligence theory.

年龄对韦氏简明智力量表第二版微妙和综合得分的影响。

我们在韦克斯勒简明智力量表第二版（WASI-II）标准化样本中评估了年龄效应。这扩展了使用先前版本的韦克斯勒成人智力量表完成的工作。在四个子测验中，词汇（VC）和相似性（SI）对衰老的抵抗力最强。VC表现出最小的变化，与年龄无关；SI在30至54年达到峰值，随后下降。块设计（BD）和矩阵推理（MR）显示，从年轻到年长的群体有显著下降。BD在17至44岁时达到峰值，然后下降；MR在20至29年达到峰值，然后持续恶化。WASI-II语言理解指数在30至44岁时达到峰值，随后在85至90岁时出现最大下降。感知推理指数在20至29岁时达到峰值，在65至69岁时显著下降。全量表智商在65岁之前是平均水平，随后下降。峰值表现点的微小变化和随后的下降被视为全量表智商水平的函数。结果与结晶智力和流体智力理论一致。

期刊介绍： Assessment publishes articles in the domain of applied clinical assessment. The emphasis of this journal is on publication of information of relevance to the use of assessment measures, including test development, validation, and interpretation practices. The scope of the journal includes research that can inform assessment practices in mental health, forensic, medical, and other applied settings. Papers that focus on the assessment of cognitive and neuropsychological functioning, personality, and psychopathology are invited. Most papers published in Assessment report the results of original empirical research, however integrative review articles and scholarly case studies will also be considered.
