Dyslexia is a term widely used to describe reading characterised by problems with the fluent and accurate letter or word recognition. Nevertheless, there is no consensus about the definition, origin, and diagnosis of dyslexia and the term is often used very differently by researchers and practitioners. In many cases, research findings are employed…

With just one exception, all of the volumes in Terman's Genetic Studies of Genius report the results of a longitudinal study of more than a thousand intellectually gifted children. That single exception is Volume II, Cox's single-authored "The Early Mental Traits of Three Hundred Geniuses," which instead was a retrospective study of 301…

The conceptualization of giftedness continues to be a widely debated topic within the field. Recently, there has been a shift from a psychometric view of giftedness to inclusion of conative and contextual factors. How one defines and conceptualizes "gifted" drives assessment and identification practices. Conceptualization also guides the…

After a short introduction about previous studies on extraordinarily gifted children with an IQ of over 170, this article refers to the descriptive characteristics of ten children with IQ of over 189. After this, the developmental and learning characteristics of these children are described and finally empirical research about aspects that…

The purpose of this research was to expand the criteria for the efficacy of the three short forms of the Standford-Binet Intelligence Scale to a consideration of individual differences in intelligence classification. (Author/RK)

Discrepancies between the mental age (MA) scores and the mean performance of chronological age (CA) groups in the latest revision of the Stanford-Binet Intelligence Scale are noted. A table is presented for converting published Stanford-Binet MA scores into MA scores that are congruent with the above definition. (Author)

Comparison of Stanford-Binet IQ scores obtained with the 1972 and 1960 norms of 228 children indicated that use of the 1972 norms resulted in substantially lower scores except at the lowest levels for functioning. The implications of these results were discussed. (Author)

The purpose of this study was to investigate the correlation between gain on the Stanford-Binet Intelligence Test (S-B) in compensatory prekindergarten programs, and scores on the New York State Pupil Evaluation Program (PEP), Reading Section, over three years later. Four hundred and five subjects showed a correlation of 0.42 for the pre-post S-B…

Whether or not subjects can simulate mental retardation, a consideration that has implications in criminal cases, was studied using 21 adult Caucasian males between 20 and 30 years of age, largely comprised of students and staff employees of the University of New Mexico. Subjects were asked to give genuine and simulated responses to two major test…

The study compared the performance of 35 lower SES black kindergarten children on the WPPSI and the 1972 Norm Edition of the Stanford-Binet. Contrary to the findings of previous investigations before the restandardization of the Binet, the WPPSI was found to yield a significantly higher mean IQ than the Binet. (Author)

THE RELATIVE EFFECTIVENESS OF TASK SCORES VERSUS IQ AS PREDICTORS OF ACADEMIC ACHIEVEMENT WAS INVESTIGATED, AND THE CORRELATIONS BETWEEN TASK SCORES AND IQ RE-EXAMINED. SUBJECTS WERE 99 UPPER-MIDDLE CLASS ELEMENTARY SCHOOL CHILDREN WITH A MEAN STANFORD-BINET IQ OF 126 (SD EQUALS 19). THE INSTRUMENTS USED WERE DUNN'S OBJECT SORTING TASK (OST),…

A causal-comparative study was conducted among 56 educationally disadvantaged children to determine if children who had the benefit of a home-based experience were significantly different from their peers in intellectual ability, self-concept, and cognitive style. Using the cognitive-developmental method of instruction, trained para-professionals…

AGE, SEX, AND IQ DIFFERENCES IN THE CHARACTERISTICS OF THE CONCEPTUAL PERFORMANCE OF ELEMENTARY SCHOOL CHILDREN WERE STUDIED. PERFORMANCE MEASURES WERE OBTAINED THROUGH THE USE OF DUNN'S OBJECT SORTING TASK (OST) WHICH PROVIDED SUCH INDICATORS AS SIZE OF THE COGNITIVE MATRIX, ACCESSIBILITY OF THE CONCEPTS IN THE MATRIX, AND DEGREE OF PRECISION IN…

A STUDY EXAMINED THE VALIDITY OF TWO BRIEF INTELLIGENCE SCALES, THE PEABODY PICTURE VOCABULARY TEST (PPVT) AND THE COLUMBIA MENTAL MATURITY SCALE (CMMS), TO SEE IF THESE TESTS OVERESTIMATED THE INCIDENCE OF INTELLECTUAL RETARDATION AMONG POVERTY AREA CHILDREN. THESE TWO TESTS AND AN EXPERIMENTAL MEASURE OF INTELLIGENCE, THE JOHNS HOPKINS…

A 4-YEAR RESEARCH STUDY HAS INDICATED THAT A MOTHER'S ATTITUDE TOWARD THE SCHOOL INFLUENCES THE YOUNG CHILD'S SCHOOL BEHAVIOR AND HIS ABILITY TO DEAL WITH ADULTS AND PERFORM COGNITIVE TASKS. THE SAMPLE POPULATION FOR THE STUDY WAS MADE UP OF 1,963 NEGRO MOTHERS OF 4-YEAR-OLD CHILDREN FROM ONE MIDDLE-CLASS AND FROM THREE LOWER-CLASS…
