A group of 73 normal children (ages 8 to 10) was compared to 49 age-matched developmentally dyslexic children of average intelligence on the California Verbal Learning Test for Children (CVLT-C), to determine if reading disability was associated with impaired verbal memory. Dyslexics differed significantly from controls on 9 of the 12 CVLT-C…

The purpose of this experiment was to examine lag function developmental parameters and to test a related developmental hypothesis and the predictions it generated. Fourth and eighth graders and adults were shown a series of words, one at a time, with some words presented twice. Between the two presentations of each repeated word there was one of…

This study investigated the role of imagery in the short-term retention of complex, visually presented movement sequences. Findings suggest that visual imagery may play a functional role in the free recall of modeled movements; however, there was no indication that imagery was involved in the retention of serial information.

This article examines the construct of working memory and its relationship to sentence comprehension difficulties of children with specific language impairment. Some sentence comprehension problems of these children may be related to inefficient management of working memory resources. Techniques for assessing working memory and enhancing the…

This study examined the short term recall of serially presented verbal information by 49 prelingually deafened and 39 hearing students (mean grade level 6). Findings suggest that neither discrepancy in the ordered short-term recall of verbal materials nor discrepancies in reading comprehension are directly assignable to differences in memory…

Sentences were presented to adolescents with and without mental retardation, and their memory for the object nouns of the sentences was then tested under various conditions. Results indicate that differences in sentence processing between individuals with and without mental retardation may be a result of differences in generating integrated…

Outlines a cognitive process model of abstracting, indexing, and classification that is based on text comprehension processes. Text comprehension for indexing versus other purposes is discussed, including conceptual and perceptual processing; conceptual knowledge and the development of expertise are discussed; and characteristics of short-term and…

Virtual reality (VR) that immerses users in a 3D environment through use of headwear, body suits, and data gloves has demonstrated effectiveness in technical and professional education. Immersive VR is highly engaging and appealing to technically skilled young Net Generation learners. However, technical difficulty and very high costs have kept…

This study sought to determine whether categorizing information would increase students' ability to recall that information. Two recall tests, consisting of a list of 30 words in random order and a list of the same 30 words grouped into 6 categories, was developed and administered to 2 groups of 16 fourth- and fifth-grade students enrolled in a…

Studied was the development of a variety of grammatical-sensitivity and phonological skills in normally achieving, reading-disabled, arithmetic-disabled, and attention deficit disordered children 7 to 14 years old. (PCB)

The results demonstrate a use of semantic information to circumvent an item-by-item search of memory. Similar results have been obtained in the fact-retrieval paradigm of long-term memory. (PN)

Studied relationships among short-term memory, processing speed, sequencing ability, and long-term memory information retrieval in 7-year-olds. Found that when reading ability was controlled, arithmetic ability was best predicted by processing speed, with short-term memory accounting for no further unique variance. Children with arithmetic…

Four experiments with children aged 5 through 12 tested the relationship between short-term memory (STM) and processing capacity. The results suggest that effects obtained with STM span do not provide clear indications of overall working memory development, because STM span and the processing space component of working memory entail distinct…

Four studies, involving 8 learning-disabled (LD) children with extreme memory difficulties, 8 LD children with average short-term memory skills, and 8 average children (ages 9-11), found that LD children have difficulties recalling both item and order information. These difficulties appear to be related to inefficiencies in phonological coding…

This study investigated the effect of individual differences in state anxiety on tasks tapping the central executive, phonological, and visuo-spatial components of working memory (WM). It was designed to test Eysenck and Calvo's processing efficiency theory (PET) which suggests that the phonological and executive components of WM may be important…
