This article details three examinations of communication impairment over 13 months in a man with AIDS dementia complex (ADC) and compares his performance on standardised language testing with that of two control participants. He had mild language impairments as measured on standardised tests but was severely impaired in pragmatic language skills.…

The present study focuses on math and related skills among 32 girls with fragile X (n = 14) or Turner (n = 18) syndrome during late elementary school. Performance in each syndrome group was assessed relative to Full Scale IQ-matched comparison groups of girls from the general population (n = 32 and n = 89 for fragile X syndrome and Turner…

Information on the development and functions of rostral prefrontal cortex (PFC), or Brodmann area 10, has been gathered from different fields, from anatomical development to functional neuroimaging in adults, and put forward in relation to three particular cognitive and behavioural disorders. Rostral PFC is larger and has a lower cell density in…

One hundred fifteen undergraduates rated 15 word-cued memories and their 3 most negatively stressful, 3 most positive, and 7 most important events and completed tests of personality and depression. Eighty-nine also recorded involuntary memories online for 1 week. In the first 3-way comparisons needed to test existing theories, comparisons were…

Purpose: We examine the relationship between the perceived needs and assessed needs of community-dwelling seniors. Design and Methods: Trained research assistants administered the Naturally Occurring Retirement Community Baseline Survey to 268 community-dwelling older adults in suburban Maryland. Perceived and assessed needs were measured in the…

Background: The study was conducted in an attempt to further our understanding of how working memory contributes to written arithmetical skills in children. Aim: The aim was to pinpoint the contribution of different central executive functions and to examine the contribution of the two subcomponents of children's written arithmetical skills.…

The general magnocellular theory postulates that dyslexia is the consequence of a multimodal deficit in the processing of transient and dynamic stimuli. In the auditory modality, this deficit has been hypothesized to interfere with accurate speech perception, and subsequently disrupt the development of phonological and later reading and spelling…

The use of narrative within interactive learning environments (ILEs) is widespread. Reviewing recent research in the fields of ethnography, cognitive psychology, neurobiology, discourse analysis, and education, this paper proposes a rationale for the use of narrative in ILEs. Starting with a description of the origin of narrative in the brain, the…

Due to the rapid advancements in mobile communication and wireless technologies, many researchers and educators have started to believe that these emerging technologies can be leveraged to support formal and informal learning opportunities. Mobile language learning can be effectively implemented by delivering learning content through mobile…

The present study examines how changes in the amount of on-screen text will influence student learning from a multimedia instructional unit on basic concepts of coordinate geometry. The relative effectiveness of two different versions (short-text and whole-text) of the instructional unit was examined for students who differed in terms of their…

We examined the components of first (L1) and second language (L2) phonological processing that are related to L2 word reading and vocabulary. Spanish-speaking English learners (EL) were classified as average or low readers in grades 1 and 2. A large number of children who started out as poor readers in first grade became average readers in second…

Many individuals may be limited in their ability to retrieve clear memories of positive, recurring, childhood experiences. In order to ascertain the generability of this phenomenon, researchers asked college students (n=340) whether they could recall ever having sat on a parent's lap when they were under five years of age. As predicted, only a…

In third-grade and tenth-grade subjects, results included (1) the absence of age differences in proportionalized short-term retention and (2) significant age differences in long-term retention only between groups that had received a different number of learning trials. (Author/CI)

This article synthesizes published literature comparing the cognitive functioning of children who have math disabilities (MD) with that of (a) average-achieving children; (b) children who have reading disabilities (RD); and (c) children who have co-morbid disabilities (MD+RD). Average achievers outperformed children with MD on measures of verbal…

A cognitive/metacognitive framework is presented for analysing applications tasks and responses to these. Conditions facilitating or impeding access to such tasks at the upper secondary level were identified using qualitative data analysis techniques within this framework. Strategies employed in exploiting, or overcoming these conditions were…
