Some previous reviews conclude that breastfeeding is not significantly associated with increased intelligence in children once mother's IQ is statistically controlled. The conclusion may potentially have both theoretical and methodological problems. The National Child Development Study allows the examination of the effect of breastfeeding on…

Some people hold an entity theory of intelligence: they think of intelligence as innate. In contrast, others hold an incremental theory, believing that intelligence can be changed. Previous research has shown that an incremental theory is associated with positive outcomes. The aim of this paper was to evaluate an intervention which promoted an…

New standardizations of the Coloured and Standard Progressive Matrices in Britain in 2007 and 2008 show that on the Coloured Progressive Matrices the intelligence of 4 to 11 year olds increased over the years 1982-2007 by 8 IQ points, representing a gain of 3.2 IQ points a decade, and on the Standard Progressive Matrices the intelligence of 7 to…

Given well-known difficulties in justifying the Galtonian conception of intelligence as innate general intellectual capacity, a historical explanation is required of why this problematic notion became so prominent in Britain and in the USA in the late nineteenth and twentieth centuries. Parallels are drawn between it and various features of the…

Experiences in researching the documentation of the intelligence (codename Ultra) produced by breaking Enigma at Government Code & Cypher School, Bletchley Park, 1939-45, are described. The major problems are identified and shown to lie in the obscurity of the associated processes, disguised as they were within general bureaucratic…

The relationship between elementary school children's mental ability scores and classroom performance was investigated. A strong predictive relationship between mental ability scores and classroom performance was obtained irrespective of the subjects' socioeconomic status. These findings indicate that predictions of academic performance derived…

Ninety-seven school-age children who had previously sustained a unilateral compound depressed fracture of the skull were studied using tests of intelligence and reading attainment. Intellectual impairment was significantly associated with overall severity of brain trauma. Neither the child's age at injury nor the brain hemisphere damaged had…

Results of attitude, intelligence, and creativity tests administered to 180 children, ages 10-11, indicate that school attitude is not significantly related to intelligence, creativity, sex, achievement, school attended, or class attended. (CP)

A case study of a pair of extremely deprived twin boys focuses on their verbal communication. Talkativeness alone was not regarded as a measure of intelligence, but attention was paid to the less talkative twin's greater use of imaginative speech. Speculations are made on the evolutionary role of creative speech. (IS)

Effects of the CoRT (Cognitive Research Trust) Thinking Project with slow learners in the United Kingdom is discussed. The aim of the project is to provide the framework which helps children arrive at a response to problems. (PHR)

Nine-year olds completed measures of general intelligence, visuospatial ability, and verbal fluency. Subjects were 107 Korean children and 115 British children. Found that Korean children scored higher on general intelligence and visuospatial ability and lower on verbal fluency than British children. (BC)

Over one thousand British primary schoolchildren completed the Crandall Intellectual Achievement Responsibility Questionnaire. Comparisons with earlier American data provided similar results. The Crandall scale is more closely related to attainment than to intelligence, indicating that high internalized reinforcement responsibility provides a…

This study investigated the relationship between adjustment to secondary school and 17 cognitive and noncognitive variables, including intelligence (verbal and nonverbal reasoning), academic achievement, extraversion-introversion, stable/unstable, social adjustment, endeavor, age, sex, and school form. (CP)

West Indian children in British schools tend to have lower scores than white children on conventional tests of achievement. However, when factors such as social class, length of exposure to the British educational system, and school quality are taken into account, the differences in test scores between blacks and whites narrow. A broader concept…

Claims that most instruction dealing with genetics is limited to sex education and personal hygiene. Suggests that the biology curriculum should begin to deal with other issues related to genetics, including genetic normality, prenatal diagnoses, race, and intelligence. Predicts these topics will begin to appear in British examination programs.…
