Background: Assessment of intelligence and executive function (EF) is common in complex neuropsychiatric practice. Although previous studies have shown that EF and intelligence are related, it is unknown whether these constructs relate to one another in a similar manner across different ability groups (mild intellectual disability, borderline…

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…

In this study, we examined the accuracy and dynamics of visually guided saccades in 20 adults with autism spectrum disorder, as compared to 20 typically developed adults using the Step/Overlap/Gap paradigms. Performances in participants with autistic spectrum disorder were characterized by preserved Gap/Overlap effect, but reduced gain and peak…

The effects of extended time on the writing performance of university students with learning disabilities (LD) was examined. Thirty-eight students (19 LD; 19 non-LD) completed a collection of cognitive, linguistic, and literacy measures, and wrote essays under regular and extended time conditions. Limited evidence was found to support the…

This study compared neuropsychological test performance of individuals (n = 18) with an occupational history of pesticide exposure to individuals (n = 35) with no such exposure history. Results showed that a history of pesticide-related occupation exposure led to deficits in only Digit Symbol performance. Additionally, the correlation between…

Autism spectrum disorder and attention deficit/hyperactivity disorder overlap in several ways, raising questions about the nature of this comorbidity. Rommelse et al. published an innovative review of candidate endophenotypes for autism spectrum disorder and attention deficit/hyperactivity disorder in cognitive and brain domains. They found that…

The placebo effect is any outcome that is not attributed to a specific treatment but rather to an individual's mindset (Benson & Friedman, 1996). This phenomenon can extend beyond its typical use in pharmaceutical drugs to involve aspects of everyday life, such as the effect of sleep on cognitive functioning. In 2 studies examining whether…

Experienced teachers have long asserted that children blind from retinoblastoma (Rb), a rare cancer of the eye, are of above average intelligence. To test this hypothesis, standardized verbal intelligence tests were administered to a sample of 85 children and adults, all diagnosed with the early infancy form of this condition. For 42 of the Rb…

Emotional and cognitive factors were examined in 18 children with mathematical learning disabilities (MLD), compared with 18 normally achieving children, matched for chronological age, school level, gender and verbal IQ. Working memory, short-term memory, inhibitory processes, speed of processing and level of anxiety in mathematics were assessed…

The use of accommodations for both instruction and assessment continues to be of great importance for students with disabilities. The purpose of this report is to provide an update on the state of the research on testing accommodations, as well as to identify promising areas of research likely to contribute to understanding of current and emerging…

The classification of intelligence has been a prime interest to many for over three-quarters of a century. The Wechsler scales of intelligence and the development of factor analysis have both played major roles in the shaping of psychometric thought. An examination of this joint history by means of a review of the factor analytic studies of the…

The WISC-R and WAIS were administered to 16-year-old EMH students in a test-retest design to distribute practice effects. Analysis of data revealed significantly higher WAIS scores on all levels of VIQ, PIQ, and FIQ for all groups. (Author)

Evaluated the ability of the Wonderlic Personnel Test to replicate the Wechsler Adult Intelligence Scale (WAIS) with (N=120) normal persons divided into principal and cross-validation groups. Correlations between the Wonderlic IQs and the WAIS Full Scale IQs were .93 for the main group and .91 for the cross-validation group. (Author)

Navy enlisted personnel (N=60) were administered the Recall scale of the Kahn Intelligence Test (Experimental Form; KIT) and the Digit Span subtest of the Wechsler Adult Intelligence Scale (WAIS). Scores for the KIT tasks indicate a significant transfer of data to long-term memory. (Author)

Identified groups with high and low levels of mistrust of Whites. Half of the participants in each group were then administered the WAIS by a white examiner. The remaining were tested by a Black examiner. The Black examiner-high mistrust group scored significantly higher than the White examiner-high mistrust group. (Author)
