Examined major discriminating factors for cognitive development in high-IQ and low-IQ children in child care who had been adopted after age four. Found that birth rank, maternal mental retardation, pregnancy/delivery complications, severe prematurity or low birthweight, and number of hospitalizations differentiated the two groups. Over time, IQs…

A number of studies in the United States have found that Jews obtain higher average IQs than white gentiles. This paper examines whether this is also the case in Britain. Three early studies are summarized that found that Jews in Britain have mean IQs in the range of 110-113. New data are presented for two nationally representative samples of 7-16…

In a study in which Asian-American, white, and black children in grades 2-6 in a California school district were given a battery of tests including measures of IQ, scholastic achievement, and short-term memory, factor analysis of the tests yielded two main factors identified as Level I (memory) and Level II (general intelligence) in Jensen's…

The results of this study indicate that the basic components which underlie a major portion of the motor domain of intellectually normal and educable retarded boys are tangibly coincident. (RC)

Investigates recall of toy preferences in the parents of 56 four-year-old children classified either as early readers or as nonreaders. Results indicated that early readers cannot be differentiated by IQ or family demographic information alone and that consistent toy preferences precede the acquisition of early reading skills. (Author/CI)

The frequencies of consistent, mixed, and inconsistent lateral preference patterns in 648 elementary school age children were examined. No differences were found in IQ, reading, arithmetic, or spelling achievement scores among the three groups of children, at any age or for either sex. (Author)

There were no predominant trends of reward preferences among different social classes. Both individual and social rewards effectively raised IQ scores of low socioeconomic status children and reduced the differences in IQ scores between the two groups. (Author/JAC)

Detection differences between 16 mildly mentally retarded and 14 nonretarded students aged about 16 years were studied via the presentation of high, intermediate, and low stimulus organizations of target and distractor stimuli. Implications for explaining intelligence-related differences across a range of tasks are discussed. (SLD)

The third edition of the Wechsler Intelligence Scale for Children (WISC-III) is reviewed. A comparison of the WISC-III with the Weschler Intelligence Scale for Children-Revised (WISC-R) is included. Discusses shortcomings of the WISC-III while noting that overall, there are substantial improvements in the WISC-III over the WISC-R. (KW)

In order to ascertain the extent to which older persons' levels of behavioral functioning parallel their levels of intellectual functioning, 42 female patients, aged 61-99, of an outpatient comprehensive care geriatric clinic, completed the Wechsler Adult Intelligence Scale (WAIS), the Instrumental Activities of Daily Living Scale (IADL), the…

Inequality of access to schools of various types can be conceived in at least four different ways: (1) inequality of participation (re: national social composition); (2) inequality of utilization of intellectual potential (re: the ablest from all strata); (3) inequality of chance (re: those who desire an education, regardless of potential); (4)…

Reports that no significant difference in reliability appeared between a heterogeneous and a homogeneous form of the same general science matching-item test administered to 316 sixth-grade students but that scores on the heterogeneous form of the test were higher, independent of the examinee's sex or intelligence.

Results were interpreted as supporting an inhibition deficit theory of mental retardation. (Authors)
