Background: Problematic alcohol use is characterized by disrupted associative processing of environmental clues, where problematic drinkers interpret ambiguous, alcohol-relevant clues in an alcohol-related way. The present study examined the strength of this interpretation bias in a large sample (N = 230) of light and problematic drinkers with and…

Background: Proxy quality of life (QoL) evaluation has been reported to be influenced by many factors. The present study was designed to investigate the impact that the presence of severe intellectual disability (ID) may have on proxy attribution of QoL in the instrumental assessment. Methods: The "other person" form (proxy…

In a test of life stage-specific responses to age-based stigma, older (n = 54, ages 62-92) and younger (n = 81, ages 17-22) adults were told that a task (Weschler Adult Intelligence Scale-III block design) required either (a) speed/contemporary knowledge (YA; "youth advantage") or (b) life experience/wisdom (OA; "age…

Normative comparisons are an integral component of neuropsychological test interpretation and provide the basis for an inference of abnormal function and impairment. In order to remedy a deficit of normative standards for a large number of neuropsychology tests, Mitrushina, Boone, Razani, and D'Elia (2005) used the meta-analysis of studies that…

Both testlet design and hierarchical latent traits are fairly common in educational and psychological measurements. This study aimed to develop a new class of higher order testlet response models that consider both local item dependence within testlets and a hierarchy of latent traits. Due to high dimensionality, the authors adopted the Bayesian…

On the basis of several reviews of the literature, Lynn [Lynn, R., (2006). Race differences in intelligence: An evolutionary analysis. Augusta, GA: Washington Summit Publishers.] and Lynn and Vanhanen [Lynn, R., & Vanhanen, T., (2006). IQ and global inequality. Augusta, GA: Washington Summit Publishers.] concluded that the average IQ of the…

Background: Previous research with earlier versions of the WISC and WAIS has demonstrated that when administered to people who have intellectual disabilities, the WAIS produced higher IQ scores than the WISC. The aim of this study was to examine whether these differences still exist. A comparison of the Wechsler Adult Intelligence Scale-Third…

Criteria were developed to assess sexual and racial item content bias for every item from six IQ tests. Each reference was judged as either stereotyped or not sterotyped. This analysis pointed out an overwhelming sexual and racial imbalance in item content. (Author/RL)

To examine the issue of item bias within the context of the revised Wechsler Adult Intelligence Scale (WAIS-R), judgments as to perceived item bias were sought. Independent raters nominated 53 WAIS-R items as containing possible bias. White and non-white college students nominated items as racially or sexually biased. Whereas 10 items were judged…

Reports possible validity of particular American Indian cognitive style based on the Bannatyne categories of the Wechsler Scales. Found statistically significant pattern of spatial ability, sequential ability, and verbal conceptual ability in 75 junior and senior high school Yakima Indian students. (LFL)

The gains of scores on standardized intelligence tests (i.e., Flynn effect) have been the subject of extensive debate concerning their nature, causes, and implications. The aim of the present study is to investigate whether five intelligence tests are measurement invariant with respect to cohort. Measurement invariance implies that gains over the…

To examine participant and examiner bias, graduate students posing as disabled examiners in a wheelchair administered the Wechsler Adult Intelligence Scale - Revised to 101 nondisabled college students. In terms of bias operating to influence subtest scores, only participant gender had a significant effect. Men scored higher than women on both the…

The Chinese revision of the Wechsler Adult Intelligence Scale was factor analyzed for 55 Chinese subjects with mental retardation. Results indicated a two-factor solution comprising Verbal Comprehension and Perceptual Organization factors. Analysis found no important differences in factor structure between the Chinese subjects and low-intelligence…

Items showing sex differences on the revised Wechsler Adult Intelligence Scale (WAIS-R) were studied. In a sample of 206 young adults (110 males and 96 females), 15 items demonstrated significant sex differences, but there was no relationship of item-specific gender content to sex differences in item performance. (SLD)

Intersubtest scatter on the Wechsler Adult Intelligence Scale-Revised for China (WAIS-RC) for 1,979 subjects was evaluated and compared with that of the WAIS-R standardization sample. Findings were similar, and differences in scatter range may be explained by cultural differences in values, educational approaches, and educational opportunities.…
