Some researchers have argued that discrepant broad index scores invalidate IQs, but others have questioned the fundamental logic of that argument. To resolve this debate, the present study used a nationally representative sample of children (N = 1,200) who were matched individually for IQ. Children with significantly uneven broad index score…

Patterns of sensory abnormalities in children and adults with autism were examined using the Diagnostic Interview for Social and Communication Disorders (DISCO). This interview elicits detailed information about responsiveness to a wide range of sensory stimuli. Study 1 showed that over 90% of children with autism had sensory abnormalities and had…

Stanford Binet: Fourth Edition (SB:IV) assessments have been collected longitudinally for 195 individuals with Down syndrome. This article discusses individual assessments which were selected for their ability to highlight major concerns that practitioners need to consider when interpreting intelligence test scores with this population. In this…

This investigation (with 30 normal students and 30 students with reading disabilities, ages 7-15) examined the relationship between intelligence and phonological coding when ability was defined according to the Planning, Attention, Simultaneous, Successive (PASS) cognitive processing model. Findings indicate that phonological problems may not be…

The position that intelligence and achievement are essentially different measures of the same construct has often been referred to as a "jangle fallacy." Such a position challenges the present practice of placing children in learning disabilities programs based on a discrepancy between Intelligence Quotient (IQ) and achievement. This…

Arthur Jensen replies to the critique by Steven Selden. He points out that scientists' choices of subject matter are subjective, but heritability of intelligence is no longer argued among experts. (MD)

Based on data gathered during their public elementary school education, two groups of 49 students in private and public schools were matched on age, ethnicity, gender, socioeconomic status and IQ. Their achievement test scores as high school seniors do not support the claim that private schools necessarily effect higher achievement. (BS)

Examines the mental development scores for two groups of at-risk infants throughout their childhood--those classified as small for gestational age (SGA) and those twins falling below 1,750g birth weight--and determines that SGA twins showed only a modest deficit in IQ scores as compared to the full twin samples. (HOD)

Eighty children, ages 3 to 17, with autism or Asperger's syndrome and mild to severe distress in the presence of some sounds received either auditory training or a control condition of listening to the same music. Significant improvements in behavior, severity of autism, and IQ were achieved and maintained for 12 months by both groups. (Author/DB)

This study compared working memory in 28 high-functioning autistic individuals (ages 7-18) with that of 30 individuals with Tourette Syndrome or typically developing. No group differences were found. Performance was significantly correlated only with age and IQ. Results suggest that working memory is not an executive function seriously impaired in…

Forty-six institutionalized adults with mild or moderate mental retardation were administered the Vineland Adaptive Behavior Scales (socialization domain), a subjective measure of quality of life, and a facial emotion recognition test. Facial emotion recognition, quality of life, and social skills appeared to be independent of one another. Facial…

This study examined the relationship of self-concept to intelligence, anxiety, and academic persistence and achievement among young adolescents in a rural school division in Saskatchewan. Eighty-five students in grades 7 and 8 were administered the Piers-Harris Children's Self-Concept Scale, Sarason's Test Anxiety Scale, Sarason's General Anxiety…

National concern over the serious decline and poor performance of United States students in mathematics and science is reflected in this paper which discusses and compares performances and behavioral characteristics of Japanese students with their United States counterparts and, in some instances, with students from Sweden, Australia, England,…

The study compared play among five groups of children (ages 3-7 years): normal children (N=41); those diagnosed with language delays (N=241), those with autism but normal intelligence (N=71), those with autism and mental retardation (N=97), and those with nonautistic mental deficiency (N=86). Each child was evaluated using a 25 minute structured…

This study examines the nature of the highly variable black-white difference across diverse tests and indicates the major systematic source of this between-population variation, namely, Spearman's g. Eleven large-scale studies (discussed in the appendix), each one comprising anywhere from 6 to 13 diverse tests, show a significant and substantial…
