This study investigated the relationship between measures of speed of cognitive information processing and intelligence test scores. Cognitive processing measures were significantly related to IQ scores. Reaction time tests measure cognitive operations basic to intelligence, and individual differences in intelligence are partly due to variability…

In 2 studies with 85 and 88 undergraduates, respectively, peripheral nerve conduction velocity (NCV) was significantly correlated with IQ score and reaction times, and NCV and reaction time contributed significantly, in combination, to prediction of IQ. Results are interpreted in terms of a neural efficiency model of intelligence. (Author/SLD)

Group and individually administered measure of intelligence were related to laboratory based measures of human information processing on a group of college freshmen. Among other results, high IQ was related to right hemisphere efficiency in processing non-linguistic stimuli. (Author/JKS)

Two methodological issues involved in determining the relationship between learning and general intelligence were examined: (1) the use of learning strategies in a paired-associate task and (2) the importance of time (rather than errors) in the measurement of learning efficiency. (Author/RD)

The general ability factor (G), as enunciated by Charles Spearman in the model of cognitive functioning, has been the foundation of psychometric theory and test making practices for 80 years. Through these decades, some psychologists disagreed with this theory, especially Godfrey Thompson and E. L. Thorndike. Nevertheless, various aptitude tests…

Theoretical implications of individual differences among infants in responsiveness to visual novelty being predictive of later intelligence differences are discussed. Issues discussed include: continuity of intelligence over development, relation of aspects of information processing to intelligence, role of hereditary and environmental influences…

In two six-month longitudinal studies of intellectually advanced preschool children, letter naming time and background digit span were moderately good predictors of concurrent reading achievement, while no other standard cognitive indices, including mental age, were associated with reading achievement. Both memory span and retrieval were related…

Sources of continuity among nine measures of infant cognitive processing and later childhood intelligence quotient were examined through developmental structural equation models applied to a sample of 208 twin pairs measured from 7 to 36 months. Skills assessed appear related to general cognitive ability in a relatively unstable manner. (SLD)

Evaluated the PREG conceptual model of human question asking. Found the model was sufficient as it accounted for nearly all of the questions produced by students, and was discriminating in that it could identify the conditions in which particular classes of questions are or are not generated.

A study explored the relation between Piagetian conservation tasks, IQ scores, and reading test scores. A series of 16 items involving conservation tasks for area, length, weight, and volume were presented to 516 students in grades four through nine. The scores on these conservation items were correlated with students' scores on achievement and IQ…

During the last two decades of work in predicting and explaining school achievement, much research has emphasized the identification and measurement of student cognitive and affective processes which predict and also promise to help explain and facilitate school achievement. This review focuses on modifiable cognitive and affective processes, as…

In an effort to validate dynamic assessment methods influenced by Vygotsky's (1978) definition of zones of proximal development (an indicator of readiness), three sets of experiments addressed two goals: the development of diagnostic assessment methods and the use of diagnostic results to guide the design of instructional programs. The first two…

This study was designed to examine the effects of auditory memory, visual memory, and vocabulary knowledge on intramodal and intermodal delayed matching-to-sample tasks. A secondary objective was to assess the value of task performance and trait measures in predicting reading achievement. A total of 52 first graders were randomly selected as…

The 4th International Conference on Educational Data Mining (EDM 2011) brings together researchers from computer science, education, psychology, psychometrics, and statistics to analyze large datasets to answer educational research questions. The conference, held in Eindhoven, The Netherlands, July 6-9, 2011, follows the three previous editions…

The present study states as its purpose the delineation of everyday transactions with the environment of a group of children observed longitudinally in their own homes and neighborhoods from age one to three. This research is considered to have been designed to answer: (1) what types of experiences are intellectually valuable to the young child;…
