In order to investigate unique and shared characteristics and to determine factors predictive of group classification, quantitative comparisons of behavioral and emotional problems were assessed using the Developmental Behavior Checklist (DBC-P) and the Vineland Adaptive Behavior Scales in autistic disorder, Williams syndrome (WS), and…

Cerebellar dysfunction and impaired cognitive flexibility are key features of autism spectrum disorders (ASD). However, despite the increasing interest in subclinical autism, no research has yet examined the relationship between these signs and autistic traits in the wider population. This study used the Autism-Spectrum Quotient (AQ) questionnaire…

This retrospective study examined scores for 111 adult participants on the Wechsler Adult Intelligence Scale-Revised, the Wide Range Achievement Test-III and the Nelson-Denny Reading Test. All participants were referred to a university clinic for learning problems. The participants were diagnosed with a learning disability, an…

A brief discussion of theories of general intelligence precedes a report of relevant empirical data. Results from the factor analysis of more than 20 sets of Wechsler Adult Intelligence Scale (WAIS) data indicate that the WAIS clearly is not a one-factor scale. It does not measure a single, general intelligence. Roughly 17 percent of the reliable…

A procedure is proposed for determining whether correlations obtained between two measures justify the assumption that the measures are identical. It is intended especially for small samples. In the example, the performance scales of two intelligence tests were administered to 32 deaf adolescents. (GDC)

Subjects with higher verbal than performance IQ's achieved significantly poorer Pascal-Suttell Bender-Gestalt scores than subjects with higher performance over verbal IQ's. The latter subjects were more likely to have dropped out of high school and to have spent some time in prison. (Author/RD)

A recent study conducted by the U.S. Centers for Disease Control estimated that approximately 7.8 percent of U.S. children ages 4-17 are currently diagnosed with Attention Deficit Disorder (ADD) or Attention Deficit/Hyperactivity Disorder (ADHD). For decades, most educators, physicians, psychologists, and parents have thought of ADD/ADHD as…

Tested traditional clinical hypotheses about the cognitive functioning of individuals (N=16) with an obsessive or an hysteric style in a nonpathological population. Results supported the likelihood that nonpathological forms of the two styles display patterns of cognitive functioning similar to those of their more pathological counterparts. (LLL)

When conducting psychological evaluations, clinicians typically assume that individuals being evaluated are putting forth maximal effort and are not exaggerating or magnifying symptom complaints. Recent research, however, suggests that students undergoing post-secondary-level assessments to document learning difficulties may not always put forth…

Subjects were randomly assigned to one of three groups: standard WAIS administration; a praise condition with praise for each correct WAIS response; and a self-monitoring condition with direct feedback on response accuracy. Results indicated that specific feedback is effective in inducing IQ test performance change in normal adults. (NG)

This study investigated the relationship between Jensen's Level I-Level II mental abilities and how they correlate with problem solving in college students. The Level I-Level II correlation was not significant, but intelligence and problem solving were significantly correlated. Results are discussed in relation to prior findings. (Author/RD)
