Evidence suggests that scores on various intelligence tests have been rising at a fast rate. To find out whether performance on the Wechsler Adult Intelligence Scale (WAIS) Vocabulary subtest has also been rising, the authors searched major psychology journals for investigations involving healthy younger and older adult participants and collected the reported WAIS Vocabulary scores. The meta-an...

Using a procedure that eliminated repetition of identical items, thus avoiding order effects, we administered the Wechsler Adult Intelligence Scale (WAIS) and the WAis-Revised to 108 subjects. AH correlations between the two tests were significant and similar to those reported in the WAISR manual. For the group as a whole, verbal, performance, and full scale IQ scores on the WAIS-R were signifi...

objective: bone marrow transplantation is considered one of the main procedures used in the treatment of both malignant and non-malignant diseases. psychological factors after bone marrow transplantation have an important role in the survival of the patients undergoing this procedure. method: in the present study, some parameters including depression, anxiety and cognition were assessed during ...

Performance on a cognitive test can be viewed either as measuring a unitary function or as reflecting the operation of multiple factors. Individual subtests in batteries designed to measure human abilities are commonly modeled as a single latent factor. Several latent factors are then used to model groups of subtests. However these latent factors are not independent as they are related through ...

Assessor bias variance exists for a psychological measure when some appreciable portion of the score variation that is assumed to reflect examinees' individual differences (i.e., the relevant phenomena in most psychological assessments) instead reflects differences among the examiners who perform the assessment. Ordinary test reliability estimates and standard errors of measurement do not inher...

This study developed regression algorithms for estimating IQ scores using the Canadian WAIS-III norms. Participants were the Canadian WAIS-III standardization sample (n = 1,105). The sample was randomly divided into two groups (Development and Validation groups). The Development group was used to generate 12 regression algorithms for FSIQ and three algorithms each for VIQ and PIQ. Algorithms co...

Base-rate data on subtest scatter for the WAIS-R was obtained from a sample of 200 healthy subjects recruited to match the adult UK population in terms of age, sex and social class distribution. Tables are presented which permit an assessment of the abnormality (i.e. rarity) of an individual's pattern of WAIS-R performance in terms of subtest range and subtest deviations from an individual's su...

Three-hundred and two psychiatric inpatients (166 women and 136 men) completed Masling, Rabie, and Blondheim's Rorschach Oral Dependency (ROD) Scale and the Weschler Adult Intelligence Scale Revised (WAIS-R). As predicted, ROD scale scores were unrelated to WAIS-R scores in subjects of either sex. These findings support the discriminant validity of the ROD scale as a measure of interpersonal de...

In several studies, suppressed Digit Span performance has been proposed as a potential marker for deliberately poor performance in a neuropsychological evaluation. The purpose of this study was to document Digit Span performance patterns in the Wechsler Adult Intelligence Scale-Third Edition (WAIS-III; ) standardization sample and selected clinical groups. Base rate tables were generated for th...
