A clinical memory test was administered to 38 high-functioning children with autism and 38 individually matched normal controls, 8-16 years of age. The resulting profile of memory abilities in the children with autism was characterized by relatively poor memory for complex visual and verbal information and spatial working memory with relatively intact associative learning ability, verbal workin...

The clinical utility of the Medical Symptom Validity Test (MSVT) for soldiers returning from service in Operation Iraqi Freedom or Operation Enduring Freedom was preliminarily investigated through retrospective chart review. Results showed that 17%, or 4 of 23, Operation Iraqi Freedom/Operation Enduring Freedom patients at a Polytrauma Network Site (Level 2), performed below cut-offs on the MSV...

Objectives. To develop an Index-based, seven subtest, short-form of the WAIS-III that offers the same comprehensive range of analytic methods available for the full-length version Design and Methods. Psychometric Results. The short-form Indices had high reliability and criterion validity. Scores are expressed as Index scores and as percentiles. Methods are provided that allow setting of confide...

OBJECTIVE This study examined the validity of a computer-based cognitive test that was recently designed to screen the elderly for cognitive impairment. DESIGN Criterion-related validity was examined by comparing test scores of impaired patients and normal control subjects. Construct-related validity was computed through correlations between computer-based subtests and related conventional ne...

INTRODUCTION Insufficient literature exists regarding the clinimetric properties of the Upright Motor Control Test Knee Extension and Flexion subtests (UMCT-KE and UMCT-KF, respectively). This study examined the interrater and test-retest reliability of these subtests, and determined the relationship between the UMCT-KE and a clinical measure of muscle function in a sample of adults with chroni...

AIM The MATRICS Consensus Cognitive Battery (MCCB) assesses seven cognitive domains with 10 subtests. This domain structure has not been demonstrated. Three factors have been produced in US samples. We examined the dimensional structure of the Norwegian MCCB. In addition, we studied the contribution of each subtest to the battery sum score. METHODS The participants were 131 patients with schi...

Article history: Received 30 November 2012 Received in revised form 31 January 2013 Accepted 5 March 2013 Available online 27 March 2013 Black/White differences in mean IQ have been clearly shown to strongly correlate with g loadings, so large group differences on subtests of high cognitive complexity and small group differences on subtests of low cognitive complexity. IQ scores have been incre...

Many symptom validity tests (SVTs) assess performance validity via declarative memory paradigms. One widely used SVT, the Word Memory Test (WMT), uses a variety of memory tests to assess performance. It is well known that declarative memory requires the hippocampus and related medial temporal lobe structures. In the present study, WMT performance was examined in nonlitigating amnesic subjects (...

The present study explored the discriminative validity of the motor-free Test of Visual-Perceptual Skills (TVPS) as an assessment for adults. The subjects were 26 learning-disabled and 26 normal young men. Overall, the subjects with learning disabilities made significantly more errors and took significantly more time on the total TVPS than did the normal subjects. The group with learning disabi...

The working memory (WM) construct is conceptualized similarly across domains of psychology, yet the methods used to measure WM function vary widely. The present study examined the relationship between WM measures used in the laboratory and those used in applied settings. A large sample of undergraduates completed three laboratory-based WM measures (operation span, listening span, and n-back), a...
