Twenty-eight children (ages 5-13) with mental retardation, hyperactivity, and inattentiveness were administered fenfluramine and methylphenidate. Fenfluramine was superior to placebo on the memory task, whereas methylphenidate reduced commission errors on a continuous performance test. Methylphenidate caused shorter response times whereas…

Explains three learning theories (i.e., behaviorism, cognitivism, and constructivism) and examines how each can be used for planning and conducting instructional design activities. Historical foundations are discussed, and comparisons are made concerning how learning occurs, the role of memory, how transfer occurs, and types of learning. (Contains…

Examines information-processing differences among four types of readers differing in reading comprehension and speed. Finds that good comprehenders outperformed poor comprehenders on all types of tasks, but the results were less clear for the high- and low-speed readers. Proposes differences in working memory as a source of individual differences…

A model of category effects found in reports of episodic memory is proposed. The model holds that stimuli are presented at a fine-grain level of detail and a category. Four experiments involving a total of 131 University of Chicago (Illinois) students and faculty are reported in support of the model. (SLD)

Recorded three- and four-year-olds' questions, their parents' answers, and information that was discussed during a conversation. The number of questions which the children asked predicted the degree to which they remembered the answers to their questions. (Author/BB)

Two focusing hypotheses were evaluated. First, do adjunct questions, focusing on science concepts and inserted after computer-animated sequences, selectively alter students' attentional processing and thus produce differential learning effects? Second, to these questions still provide enough metacognitive scaffolding to produce differential…

Potential mechanisms mediating the facilitative effects of elaborative interrogation on associative memory were investigated with Canadian university students reading facts about Canadian provinces. One hundred subjects answered "why" questions about each fact, whereas 10 subjects in the control group did not. Conditions under which…

Examined study time and recall on the part of learning-disabled and nondisabled children of five ages. Children performed a task requiring recall of digits that were presented at the child's own rate. Recall and study time increased with age and were higher in nondisabled children. (SH)

Experiments were conducted on the speed of encoding differences between 15 school-age individuals with and 15 individuals without mental retardation, while retaining a full memory load or half memory load. Subjects with mental retardation allocated fewer attentional resources to encoding, even though encoding may require more of their resources…

In a study of knowledge activation and sentence mapping, subjects read stories that described concrete actions, and then the content of the stories was manipulated (i.e. stories were written that implied different emotional states). It is suggested that the more emotionally evoking situations one encounters the more memory traces are stored and…

How lecture note taking influences writing processes was studied in 4 experiments involving 392 undergraduates. The writing model of L. S. Flower and J. R. Hayes (1981) served as theoretical foundation. Results support the effects of external storage and encoding plus internal storage on writing processes. (SLD)

Investigated the effect of children's problem schemata and working memory span on the accuracy of children's solutions of arithmetic word problems. Results supported the hypothesis that the amount of working memory resources activated is independent of schemata activation, and indicated a weak relationship between memory and problem-solving…

Studies whether global, causal inferences are made during comprehension. Provides verbal protocol data in the form of talking aloud during reading. Discusses the data with reference to processing claims and working-memory models. Considers what verbal protocols reveal about processing. (HB)

Two experiments involving 49 3- and 47 4-year-old French preschoolers studied their memories for racial and other social information to test claim that perceptual factors are integral to derivation and representation of racial categories. Results cast doubt on claim that perceptual information is crucial component of racial categories and are more…

This article reviews research on mathematics learning and forgetting, especially for students with learning and other disabilities. It notes the important role of mathematical language and the substantial loss of mathematics achievement over the summer vacation. Year-round schooling is encouraged to eliminate prolonged interruptions in…
