Compares performance of 172 children aged 7 to 13 years on tasks involving visual or auditory presentation of rhyming and nonrhyming letters and an oral or written response. Results indicate insensitivity to phonological similarity for young children with disabilities; sensitivity improves with age, but deficits in short-term memory remain at…

The aims of this study were (1) to assess the relative effectiveness of verbal and visual elaboration prompts and question-answering prompts on children's incidental memory, and (2) to determine whether performance improvement associated with pictorial elaboration could be augmented by either verbal elaboration or question-answering procedures.…

A study of 21 patients with Alzheimer's Disease and 25 with vascular dementia, the two most common forms of dementia, investigated language impairments in the dementia syndrome to see if analysis of language disturbances is helpful in differential diagnosis. Diagnostic assessment included a neurological examination, detailed medical history,…

The verbal encoding ability of 24 students (ages 14-20) with learning disabilities (LD) was compared to that of 24 non-learning-disabled subjects. LD subjects did not show a release from proactive interference, suggesting that such students are less likely to encode the phonetic features of words or use a phonetic code in short-term memory.…

Second-grade children were explicitly supplied with zero, one, two, or three components of information to specify the respective contributions of various sources and amounts of acquired strategy-utility information. Metacognitive knowledge was evidenced only when the training regiment included the complete set of critical metacognitive components.…

A stages-of-learning model was used to examine effects of picture-word manipulation on storage and retrieval differences between disabled and nondisabled grade 2 and 6 children. Results showed that disabled students are poorer at memory tasks and in developing the ability to reliably retrieve information than nondisabled children. (Author/RH)

This study investigated the tendency of deaf children (ages 6-13) not to spontaneously use active memory strategies such as rehearsal. Comparison of 38 deaf and 39 hearing students found that deaf students compensated for less effective rehearsal strategies by capitalizing on unique spatial features of the task. (Author/DB)

Two experiments examined hyperactive children's tendency to underfocus their attention during learning. Taken together, the results of both experiments demonstrated the validity of the attentional diffusion hypothesis and indicate the need to assess the central processing demands associated with central and incidental learning in order to evaluate…

Twenty-four children (aged 7-16 years) with seizure disorders (SD) were compared to 30 children with diabetes mellitus (DB) and 30 children with no chronic illness. Using a variety of assessment devices, the children were compared on intelligence, academic achievement, attention, memory, perceived competence, and parents' perceptions of child and…

Investigates the extent to which learning disabled readers' atypical encoding relates to their deficiencies in semantic memory by comparing learning disabled and nondisabled readers in two age groups on dichotic listening tasks that included orienting and nonorienting instructions. (HOD)

Forty-five gifted children, ages 11-17, were tested with the Stanford-Binet Intelligence Scale and the Woodcock-Johnson Tests of Achievement. Results indicated 18 of 20 correlations between the area and composite scores were significant. The Stanford-Binet Short-Term Memory standard age score mean was lower than other scores' means. (Author/JDD)

Prior studies have often confounded linguistic and perceptual performance when evaluating deaf subjects' skills, a confusion that may be responsible for results indicating lesser recall ability among the deaf. In this series of studies this linguistic/perceptual confound was investigated in both the iconic and short term memory of deaf…

Investigated relationships among metamemory, memory behavior, and memory performance of children aged 4 to 6 in two experiments. Results indicated an increase in preschoolers' ability to establish relationships between cues and targets even if these were not highly associated. (RWB)

This research compared the effects of a televised presentation and a picture book on children's recall of specific verbal and visual content using 48 third-grade students in Florida as subjects. The children were first stratified by sex and then randomly assigned to view the same story in either a picture book with audiotape or a televised…

Until recently it has been possible only to measure the behavioral products of cognitive processing, e.g. reaction time. However, this is a rather indirect way of studying brain substrates of cognition. Psychophysiological techniques can be used to study the neural mechanisms of cognition. In this experiment brain electrical activity was measured…
