Thorndike's Stanford-Binet data suggest that from 1932 to 1971-72 preschool children enjoyed greater IQ gains than older children, possibly due to the rise of television. Additional analysis indicated that gains were either due to sampling error or totally antedated 1947. Gains of 12 IQ points were found for Americans. (Author/EGS)

Analysis of the variables measured on the General Aptitude Tests Battery and the Metropolitan Achievement Tests indicates that while achievement ratings are related to in-school and post-school success, aptitude testing may not be as effective a method as believed for vocational placement. Extensive literature review. Data tables. (CJ)

Describes recent developments in intelligence theory, applied measurements, and research methodology that suggests new research is needed to reexamine the relative importance of both general and specific cognitive abilities in explaining school achievement. Presents summary of results that examines relationship between "g" and seven…

This commentary documents errors in the statistical analyses and interpretation of empirical evidence in "The Bell Curve" by R. Herrnstein and C. Murray (1994). "The Bell Curve" neglects the role of education and grossly overstates the case for IQ as a determinant of social success. (SLD)

Assertive behavior in children is characterized as manipulation and exploration of the environment. Assertive behavior can be nondestructive or destructive. It has been suggested that learning is dependent on assertion and that distortion or inhibition of assertive behavior may restrict or distort the learning process. Fifty Head Start children…

Designed to investigate the performance of American Indian youth on the "Wechsler Intelligence Scale for Children" (WISC) compared to the "Chicago Non-Verbal" (CNV) for the purpose of establishing validity and reliability of the measurement and appraisal tools, this study analyzed test data from 71 Indian youth (aged 11 to 15)…

Major tenets summarizing Jensen's two-level theory of mental abilities were examined in a static-group comparison, correlational study. Caucasian siblings in grades one through four from low- and middle-socioeconomic (SES) populations were administered five Level I (associative learning ability) tasks and Raven's Progressive Matrices. Consistent…

The present study examined the reliability of the WISC-R subtests and IQ scales when administered to Mexican-American children. In an effort to extrapolate these findings to the individual child, this study also attempted to ascertain the standard errors of measurement for each subtest and IQ scale. (Author)

The hypothesis that coping with novelty is a key aspect of intelligence is not supported by the data of Sternberg and Gastel. It is contended that these authors committed a common error by interpreting correlations involving difference scores without reference to the properties of the components of the difference. (SLD)

Correlations and mean score differences between IQs derived from the Universal Nonverbal Intelligence Test (UNIT; Bracken & McCallum, 1998) and the Wechsler Intelligence Scale for Children-Third Edition (WISC-III; Wechsler, 1991) were compared. Participants were Limited English Proficient (LEP) Mexican-American elementary school students, who…

Analyzed and compared to other disability groups were patterns of intellectual functioning in 120 institutionalized boys 10- to 15-years-old. (CL)

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),…

The Brain Wave Analyzer (BWA Ertl 02) was used to measure the brain potentials of 110 public school children. Resulting scores were correlated with concurrent measures of school achievement. Results indicate that certain brain wave scores have relatively low correlations with school achievement compared to traditional intelligence measures but may…
