Investigated were the role of mental imagery in children's logical reasoning and individual differences in children's use of imagery while reasoning. Fifth grade students assessed as being high imagers (HIS) and low imagers (LIS) completed conditional syllogisms of various kinds and were asked, after each of their responses, whether an image had…

The task consisted of categorizing a set of slides depicting concepts of freedom, nonfreedom, justice, and nonjustice. The results of the analysis indicated that abstract thinkers performed significantly better than did concrete thinkers and that performance increased as a function of grade level. (Author/BJG)

When one learns complex material, the important thing appears to be the ability to understand the material. Once understanding occurs, learning and remembering follow automatically. The conventional psychological literature says little about the processes involved in the learning of complex material--material that takes weeks, months, and even…

Explores 96 preschool children's utilization of complementary and taxonomic relations under varying task demands. Results indicated that, as task demands increased, (1) complementary intrusions produced systematic error in the taxonomic condition and (2) performance decreased in both conditions. Complementary pairs were maintained at progressively…

Four- and five-year-old children were asked to compare the burning times of pairs of partially synchronous lights differing in intensity, bulb size, or both. (Author/MP)

First year medical students answered parallel multiple-choice questions at different taxonomic levels as part of their diagnostic examinations. The results show that when content is held constant, students perform as well on interpretation and problem-solving questions as on recall questions. (Author/BW)

A review of research and theory on cognitive processes and their relationship to instructional technique since the early 1970s looks at the contributions of schema theory and artificial intelligence and their instructional implications, including cognitive load theory, worked examples for learning problem solving, and physical vs. mental…

This response to Brainerd and Reyna's paper (in this issue) argues that the common resources hypothesis can be applied to a wider range of phenomena than can the output-interference hypothesis. Presents results of a dual-task experiment under bidirectional deficits. Concludes that dual-task studies do not provide critical tests of the resources…

The relationship between the verbal ability of 50 fifth graders and the adaptive nature of questions they asked while trying to find vocabulary synonyms was studied. Those with high verbal ability asked more necessary questions and, when items were difficult, asked more unnecessary questions, probably to increase confidence. (SLD)

This study with 56 students (mean age 15 years) with mental retardation and 53 nonretarded students (matched for mental age) found that students with mental retardation were more likely to rely on all kinds of external cues (task-relevant, incidental, or misleading) in problem solving, especially when the preceding task had been difficult.…

This study of the haptic processing of 9 children with specific language impairment and 9 normal-language children (ages 5-7) found that both groups performed similarly when the response modality was tactile and task requirements were minimal and performed differently when response demands included cross-modal processing or increased symbolic and…

The latency and amplitude of the P300, an event-related potential, during the performance of a memory-scanning task were used as indices of the efficiency of information processing that may mediate individual differences in intelligence. Results with 61 female college students contradict a pure speed of processing explanation of the relationship…

Two experiments used Headed Records memory model to examine preschoolers' performance on a variation of Perner's Smarties task, a false-beliefs test. Data indicated that when the computational demands imposed by the original task are reduced, young children can and do remember what they had thought about the contents of a tube even after its true…
