Peer reviewedHoard, Mary K.; Geary, David C.; Hamson, Carmen O. – Mathematical Cognition, 1999
Uses neuropsychological and developmental models of number, counting, and arithmetical skills as well as supporting working memory and speed of articulation systems as the theoretical framework for comparing groups of low- and average-IQ children. Indicates that low-IQ children's conceptual understanding of counting did not differ from that of…

Peer reviewedCohn-Jones, L.; Seim, R. – American Journal of Mental Deficiency, 1978
The role of mental age (MA) and visual-perceptual ability in number concept development was examined with 48 nonretarded and retarded children from regular school settings. (Author)

Corsale, Kathleen; Gitomer, Drew – 1979
Developmental and individual differences in mathematical aptitude were investigated as a function of knowledge structure and processing variables. Results indicated the relative importance of knowledge structure and strategy skills in aptitude test performance. Protocol data further elaborated the interrelationships between knowledge and process…

Peer reviewedHolzman, Thomas G.; And Others – Journal of Educational Psychology, 1982
Developmental differences in reasoning ability and item processing demands are analyzed in a study of cognitive determinants of number analogy performance in two IQ levels of elementary school children and college students. The amount of solution-related information in working memory was the crucial processing demand. Process differentiations of…

Peer reviewedBrown, Ann L. – Child Development, 1973
The relation of CA, MA, and IQ to conservation was examined by comparing the performance of bright, normal, and retarded children matched on the critical MA of six years. (Author)

PDF pending restorationHolzman, Thomas G.; And Others – 1980
The cognitive determinants of number series completion performance were studied by presenting a systematic set of problems to adults and to children of high and average intelligence, grades 4 and 5. Pearson correlations between these problems and the number series on the Cognitive Abilities Test were .51, .78 and .43 for the average intelligence,…

The study reported here compares the performance on a mental ability test of children in grades two and three from homes in which English is the language spoken with those from homes in which Spanish is the language used. During the Spring semester, the InterAmerican Tests of General Ability, Level Two, and their Spanish parallel, were…

Holzman, Thomas G.; And Others – 1980
The cognitive determinants of number analogy performance were studied by systematically manipulating the processing demands imposed by the items. To explore sources of developmental differences in analogical reasoning, subjects were included from two age levels, grades 4 and 5 and college. To allow the investigation of individual differences in…
