Although several studies have shown that planning, attention, simultaneous, and successive (PASS) cognitive processes--operationalized with the cognitive assessment system (CAS; Naglieri & Das, 1997)--are significant predictors of academic performance in the general population, little is known about their role among children with superior…

Twenty-two children and adolescents with traumatic brain injury (TBI) were compared to a matched sample of neurologically normal children and adolescents on several measures of cognitive processing. Results are consistent with the literature demonstrating poor performance on measures of attention and executive functioning among children who have…

The visual imagery of four individuals with blindness was compared with that of five sighted individuals using the detection of mirror symmetry. The two participants who lost their sight later in life outperformed the two with congenital blindness, indicating the importance of early visual experience in visual imagery. (CR)

The influence of feedback on the cognitive task performance of 30 adults with mental retardation having either high or low self-esteem was assessed. All subjects performed two memory tasks (easy, difficult) under one of three feedback conditions (social, computer, and no feedback). Social feedback was most effective in altering the positive…

This project examined the hypothesis that different background experiences associated with cultural grouping may lead to differences in test-taking strategies which result in score differences extraneous to the abilities the test is intended to measure. Its purposes were to confirm (or disconfirm) the cultural differences hypothesis and to provide…

This study investigated the effects of prompting, or directing/controlling attention, during a reasoning task on the performance of 68 children with attention deficit disorders, learning disabilities, or no handicaps, in grades 1-12. All groups benefited from prompting, and prompting was related to a different set of cognitive processes in each…

Evaluation of the Kaufman Assessment Battery for Children (K-ABC) with 130 primary school children in Zaire revealed three findings: (1) the distinction between sequential processing and simultaneous processing was valid; (2) the K-ABC discriminated effectively among grade levels, health and family environment variables, and tribal membership; and…

A model of conceptual learning and development that provides a framework for studying the course of cognitive development throughout the school years and also studying the learning concepts across short time intervals is discussed in this paper. The theory includes five main propositions. First, children learn four successively higher levels of…
