Objective: To investigate the effects of methylphenidate (MPH) on components of working memory (WM) in children with ADHD and determine whether MPH produces differential effects on WM in children with comorbid anxiety (ANX). Method: Participants were a clinical sample of 130 children with ADHD, aged 6 to 12 years old (32% comorbid ANX). Each child…

Behavioral phenotypes of individuals with Williams syndrome and individuals with Down syndrome have been contrasted in relation to short-term memory. People with Down syndrome are stronger visuospatially and those with Williams syndrome are stronger verbally. We examined short-term memory, then explored whether dual-task processing further…

Two disparate research programs have addressed the challenge of instructional multimedia design. One, based on cognitive load theory, has focused on ways of reducing unnecessary cognitive load during instruction to free up resources for learning. The other, based on constructivism, has centered on interactive multimedia, allowing students to build…

The aim of this study was to investigate the relationship between working memory capacity and L2 reading comprehension of both linear texts and hypertexts. Three different instruments were used to measure comprehension (recall, comprehension questions and perception of contradictions) and the Reading Span Test (Daneman & Carpenter, 1980) was…

The Number Sets Test was developed to assess the speed and accuracy with which children can identify and process quantities represented by Arabic numerals and object sets. The utility of this test for predicting mathematics achievement and risk for mathematical learning disability (MLD) was assessed for a sample of 223 children. A signal detection…

The current study was devised to determine the short-term (1 month) and long-term (4 months) effects of having students generate their own examples of selected concepts. More specifically, focus was on determining how self-generated examples might enhance the learning and retrieval of concepts. Subjects were 55 (54 female and 1 male) undergraduate…

Nouns were presented in triads as pictures, printed words, or spoken words and followed by various types of interference. Measures of short- and long-term memory were obtained. In short-term memory, pictorial superiority occurred with acoustic, and visual and acoustic, but not visual interference. Long-term memory showed superior recall for…

Reasons for poor performance on the Digit Span subtest of the Wechsler Intelligence Scale for Children-Revised were examined, using learning disabled (LD) children who performed poorly on the test, LD children who performed normally, and average children. One LD group was unable to establish mnemonic codes for familiar auditory stimuli.…

Reports three experiments demonstrating that recall for words increases with deeper levels of processing and with longer rehearsal intervals. Asserts that there is no interaction between those strategies. (PMJ)

Two experiments on children's inferences and associative memory provided a supportive test of fuzzy-trace theory. Results indicated that false recognition of associated instances with delay declined for all children, and categorical inferences increased for older children. Verbatim memory and inferences were uncorrelated under short delay but…

Investigated effects of object reinstatement on event recall by 6- and 9-year olds'. Subjects were interviewed either 10 days and again 10 weeks after an event, or only 10 weeks after an event. Interviewing included free recall, prompts, and questions. Found that age, delay, and object reinstatement all affected amount and accuracy of recall. (JW)

Describes the biological basis of learning and individuality. Presents an overview of recent discoveries that suggest learning engages a simple set of rules that modify the strength of connection between neurons in the brain. The changes are cited as playing an important role in making each individual unique. (MCO)

Describes a software package entitled the "Computerized Cognition Laboratory" that helps integrate the teaching of cognitive psychology and research methods. Allows students to explore short-term memory, long-term memory, and decision making. Can also be used to teach the application of several statistical procedures. (DSK)

Examined how elementary school students remember what they learn and how they learn in science and social studies. Found that students used long-term working memory for sorting, interpreting, and integrating representations of classroom experiences as they acquired knowledge and skills. Recollection 12 months later replaced details with inferences…

The authors found that the order of attribute presentation had a stronger effect on judgment in English than in Chinese. In Experiment 1, with a sample of 102 female and 63 male bilingual Singaporeans, the authors found that participants' memory-based judgments showed a stronger primacy effect in English than in Chinese that was mediated by recall…
