This article argues that one dominant position in psychology, linguistics, neuroscience, and philosophy about how genetic disorders point to the innate specification of dissociated modules in the human brain should be replaced by a dynamic, neuroconstructivist approach in which genes, brain, cognition, and environment interact multidirectionally.…

The objective of the current study was to evaluate the patterns of longitudinal change in the language abilities of 28 children with autism during early and middle childhood. Results from fitting a series of multilevel models showed that children's rate of language growth was independently predicted by (a) children's responsiveness to others' bids…

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…

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)

This study with 12 elementary school children with mild mental retardationship found that the relation between lexical knowledge and mental age depended upon the nature of the vocabulary test. Results suggested that mental age in this population was more strongly related to knowledge of abstract relational terms than to knowledge of labels for…

Applies the confluence model to a longitudinal intact family data set. Also tests the data with simple linear models. Results suggest that the confluence model should be rejected as a useful model for these data based on principles of parsimony and predictability. (Author/AS)

Four hundred subjects 8 to 11 years old were given a modification of the Weigl Color Form Sorting Test in an attempt to assess the influence of chronological age, mental age, intelligence, and vocabulary level on the ability to utilize various numbers and different kinds of criteria of classification.

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)

Reviews the major contributions of Alfred Binet. Explains why the fame of the Binet-Simon Intelligence Scale was so long lasting whereas that of his other contributions was so fleeting. Discusses implications of his contributions for current efforts to formulate unified theories of cognition and cognitive development. (Author/GLR)

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.…
