Retarded subjects were compared with mental- and chronological-age matched controls on serial short-term memory (STM) tasks. Retarded subjects were inferior to the control groups on both primacy and recency items, under two recall conditions. These data are discussed in relation to possible mechanisms underlying IQ-related individual differences…

This study examined the utility of Wechsler's Deterioration Index, which compares short- and long-term memory capabilities. Three studies with a total of 120 children (ages 6-14) found that the index did not predict learning disability status but did distinguish children with attention deficit hyperactivity disorder from nondisabled children.…

This study formulated and tested a mathematical model to predict learning in which the amount of correct information recalled from an audio learning task is a function of the rate of oral communication. (Contains 36 references.) (MDH)

Investigated the effects of writing systems on Chinese subjects' decoding strategies in both Chinese and English. Results suggest that both writing systems and learning environment are significant factors to subjects' application of graphic, phonological, or semantic strategies in decoding Chinese and English words.

The present study investigated the relation between executive functioning and symptoms of Attention-Deficit/Hyperactivity Disorder (ADHD) and Oppositional Defiant Disorder (ODD) in children aged 4-6. A population-based sample (n = 201) was used and laboratory measures of inhibition, working memory and verbal fluency and teacher ratings of…

Background: Deficits in executive functioning are supposed to have a predisposing influence on impulsive or aggressive behaviour. We tested the hypothesis that oppositional-defiant disorder (ODD) children with or without attention deficit hyperactivity disorder (ADHD) have problems in executive functioning. Method: Seventy-seven 7- to 12-year-old…

This research investigated the frequency discrimination performance of a 6-year-old boy (MH) with language and attentional difficulties. MH had been reported to have literacy problems not paralleling an advanced verbal ability, and he showed difficulties in discriminating non-verbal tones of different frequencies in comparison with children of his…

This study investigated the impact of recency effect on multiple rule-based problem solving in an interactive multimedia environment. Forty-five college students were recruited and assigned to two groups: synchronized and unsynchronized interactive multimedia groups based on their spatial ability score. Results show that students in the…

Cognitive processing limitations restrict the number of complex information items held and processed in human working memory. To overcome such limitations, a verbal working memory channel is used to construct an if-then proposition representation of facts and a visual working memory channel is used to construct a visual imagery of geometric…

In college-level courses, the vast majority of students read expository textbooks with a primary purpose in mind: to memorize and, hopefully, understand enough information to receive a particular grade on a course exam. Intuitively, this kind of reading is different than the kind of reading that these same students do when reading a novel while…

The primary aim of this study was to determine whether a phonological awareness intervention promoted oral English proficiency more than a story-reading condition for Spanish-speaking kindergarten children, most of whom were limited English proficient. A second aim was to determine the extent to which change in English proficiency over the course…

This publication contains reports on six research projects proposed, developed, and conducted by teachers in their own classrooms. The projects were conducted during the 1995-96 school year. The projects are: (1) "M..M..M..Math (Making More Meaning out of Math)" (Naomi Rose); (2) "Effect of Student Achievement as a Result of Individualized Use of…

The focus of the study reported here was to investigate people's comprehension ability as a function of the number and type of negations embedded within sentences similar to those which might appear as premises in syllogisms. The subjects were one group of 11 Hispanic and four groups of Anglo students, with 15 in each Anglo group. Thirty-two…

The effectiveness of a strategy for remembering words from a word list was investigated in subjects who were high in test anxiety versus subjects who were low in test anxiety. Sixty seventh-grade volunteers from two urban junior high schools were assigned to the strategy training group or the control group. The strategy group was instructed to…

Research developments in cognitive psychology, and their implications for teaching and learning at the level of professional education, are summarized. Areas discussed include organization of long-term memory, influences on storage and retrieval from memory, problem solving and transfer/use of analogy, concept formation/categorization/pattern…
