Intellectual engagement (IE) refers to enjoyment of intellectual activities and is proposed as causal for knowledge acquisition. The role of IE for cognitive development was examined utilizing 2-year longitudinal data from 112 ninth graders (average baseline age: 14.7 years). Higher baseline IE predicted higher baseline crystallized ability but…

This longitudinal randomized-control trial investigated the effectiveness of scientifically based reading instruction for students with IQs ranging from 40 to 80, including students with intellectual disability (ID). Students were randomly assigned into treatment (n = 76) and contrast (n = 65) groups. Students in the treatment group received…

Comparison of the mental status of 30 subjects with Down's Syndrome mosaicism and 30 matched subjects with trisomy 21 Down's Syndrome found that the mean intelligent quotient of the mosaic Down's Syndrome group was significantly higher and that this group showed better verbal abilities and more normal visual-perceptual skills.

Comparison of 384 male and 91 female autistic children (three through eight years old) revealed that females as a group scored less well on intelligence tests. Boys also performed better than girls on eye-hand integration and perceptual tasks. Predictions of female superiority in affect and receptive vocabulary were not supported. (CL)

Significant differences in IQ and measures of motor development were found between twenty-four inadequately and sixteen adequately nourished New Delhi preschool children from lower middle class homes. Former showed greater variability than the latter, and girls in the former category had lower mean scores than boys in the latter. (RJ)

Compares a group of 32 toddlers with employed mothers with a matched group of 38 toddlers with nonemployed mothers in order to examine the effect of maternal employment on the development of the child. While no differences were found between the two groups in language development and emotional adjustment, children of employed mothers were more…

The objective of this study was to develop and evaluate two procedures for providing preschool education for rural 4-year-olds by using a mobile laboratory. The project used "readimobiles" to determine the effectiveness of a structured, psycholinguistically-based preschool curriculum on black, disadvantaged children. There were three…

A study was conducted to determine if verbs were learned as easily as other words by primary school children. One hundred eight kindergarten children were divided into high, medium, and low I.Q. ranges and each range group was further divided--one group for each of three testing methods at each intelligence level. A list of words including 25…

In behavioral science research, language has been increasingly seen to reflect the concepts that the child has acquired prior to, and hence independent of, the acquisition of language. Analyses based on this idea are confined largely to words that denote clear perceptual referents. Language, however, contains many terms that have no portrayable…

THE EFFECTS OF TWO INSTRUCTIONAL APPROACHES, THE COORDINATED, BASAL LANGUAGE ARTS APPROACH AND THE INTEGRATED EXPERIENCE APPROACH TO COMMUNICATION, ON PUPILS' LANGUAGE DEVELOPMENT WERE EXAMINED. APPROXIMATELY 600 FIRST-GRADE STUDENTS WERE ASSIGNED RANDOMLY TO THE TWO APPROACHES. APPROXIMATELY 500 PUPILS COMPRISED THE FINAL, TOTAL PUPIL POPULATION…

The development of social maturity, language, and arithmetic abilities was studied over a 3-year period in 103 mentally retarded children from high IQ (51-75) and low IQ (26-50) groups in special schools and special classes. Among findings were that the high IQ groups of both special classes and special schools showed much improvement over the…
