Purpose: Many observations and anecdotes have suggested that individuals with Down syndrome (DS) love music, specifically moving to music. The purpose of this study, with the assumption that the music makes people with DS dance showing more movement than general public's, is to observe the change in movement patterns of people with DS while they…

Background: Individuals with intellectual disabilities (ID) show difficulties with everyday planning. A tablet-based training program for everyday planning may be a suitable intervention, but its feasibility must be evaluated. This study evaluated how behavior changes during training and if individuals with ID can use technology by themselves.…

General cognitive and specific number abilities that underlay arithmetic performance have been heavily investigated among typically developing students; however, the inquiry has rarely been applied to students with mild intellectual disability (MID). We examined whether domain-general cognitive abilities (i.e. working memory, processing speed, and…

Mathematics is an important aspect of daily life. Basic numeracy skills are needed to accomplish everyday tasks. However, research regarding the relationship between cognitive ability, mental age, and basic numeracy skills for children with intellectual disability (ID) is scarce. This research study investigated the correlation between…

The law of intelligence is presented in test independent form. Mental abilities, physical brain size, and infant motor capacity follow the same law of growth from birth to adolescence. Mental growth is independent of race, "SES" or the Flynn effect. The vitality of the mental age scale calls for a reexamination of Wechsler's deviation IQ. This…

Sattler's standard deviation technique for interpreting strengths and weaknesses on the Stanford-Binet Intelligence Scale has been simplified by Kaufman and Waterstreet in the form of an easy-to-use table. A refinement of their table is presented, with an example to demonstrate its use. (Author/CTM)

Elementary school students (N=29) with a mean age of 7.96 years who were referred for gifted evaluation in an affluent suburban school district in Western Pennsylvania were administered the Kaufman Brief Intelligence Test and the WISC-III. Discusses findings, limitations and implications of the study. (KW)

A series of item analyses of the Concept Assessment Kit Conservation (Goldschmid) conducted for a sample of educable mentally retarded children showed that the probability of a correct response differed from task to task. Evidence indicated that the order of difficulty of the tasks resembled that for nonretarded children. (Author)

Compared the derived mental age (MA) of the Stanford-Binet to the test age (TA) of the Wechsler Intelligence Scale for Children (Revised) in 100 children. For subjects whose WISC-R scores fell within the TA table, the two were comparable. When extrapolated TAs were required, the scores were not comparable. (Author/JAC)

Persons representing the extremes of intelligence cannot be included in the same study unless they are approximately equated on mental age, in which case the relative performances of the extreme groups can provide useful information about the nature of intelligence. (Author/RD)

A 76-item test of intellect-related personality traits was developed and administered to 46 gifted 13 year olds, 51 undergraduates, and 53 seventh and eighth graders. Three component-based traits were obtained: intellectual absorption, apathy, and pleasure. These traits were found to be related to intellectual performance. (TJH)

Do stage-related patterns of early cognitive development reported for normally developing children also characterize at-risk and handicapped children when mental age organization of data is used? Mental age predicted Piagetian-based cognitive levels one to three but did not predict highest-level symbolic functioning in 95 handicapped children.…

Among a cross-sectional sample of pupils of both sexes in Britain evidence showed accelerations in intellectual development at 7 and 16 years of age. Acceleration at the younger age is a new finding. Age, verbal IQ, teacher's estimate, and social class were all significant predictors of intellectual development. (Author/IS)

Since early research had shown that a total score on 27 Piagetian tasks was very highly correlated with a Wechsler and achievement composite, a study investigated the possibility of shortening the Piagetian test by means of classical analysis methodology. (HOD)

Finds further evidence of the close equivalence of scores derived from the Wechsler Intelligence Scale for Children (Revised) and the Stanford-Binet, but fails to support the practice of computing adjusted mental age scores. Subjects were (N=25) children in the bright normal range of intelligence. (JAC)
