The reflection-impulsivity (R-I) dimension of individual variation incognitive processes is discussed. A literature review focuses on studies that have supported the validity of the R-I dimension as a concept, and studies providing evidence of a direct relationship between the R-I dimension and visual scanningstrategies. This study compares the…

Reports the results of a high-speed search task administered to overactive and distractible (hyperactives), normoactive and distractible, and normoactive and attentive (controls) children. Instructions emphasized speed, accuracy, or both speed and accuracy. Indicates that controls and distractibles conformed to the fast guess model, which relates…

This paper reviews studies on cognitive processes that may mediate the development of early learning problems. Topics covered include auditory and visual discrimination deficits, integration of information from different modalities, the significance of attentional factors, contributions of memory factors, and the importance of cognitive style…

Research was conducted to further investigate the results of an earlier 1985 study (Dwyer, et al.) which found that a moderately externally-paced microcomputer-based instructional program was more effective than either a self-paced or a more aggressive externally-paced condition. Instructional programs (heart parts and verbal labels) were…

Illustrates how computers can assist teachers in preventing impulsivity and foster the cognitive and metacognitive development of students. Discusses theoretical aspects of impulsivity and learning difficulties; software for improving self-regulated learning, in particular the VISPRO (Visualizing Processes) project; and teacher education needs,…
