This study investigated the effects of syntactic complexity on written sentence comprehension in compensated adults with dyslexia. Because working memory (WM) plays a key role in processing complex sentences, and individuals with dyslexia often demonstrate persistent deficits in WM, we hypothesized that individuals with dyslexia would perform more…

Background: Dopaminergic therapy proved to ameliorate motor deficits in Parkinson's disease but its effects on behavior and cognition vary according to factors that include, among others, the evolution of the disease and the nature of the task that is tested. This study addressed the question of whether, in moderate to advanced Parkinson's disease…

Williams syndrome (WS) is a neurodevelopmental disorder associated with impaired visuospatial representations subserved by the dorsal stream and relatively strong object recognition abilities subserved by the ventral stream. There is conflicting evidence on whether this uneven pattern in WS extends to working memory (WM). The present studies…

The comparison of the neurocognitive functioning of people with pediatric bipolar disorder (PBD) with a control group shows that the developmental progress in executive functions and verbal memory of those with PBD was significantly less than those in the control group. The results were seen after comparing data from baseline cognitive tests and a…

Pragmatically related abilities were studied in three clinical groups of children from 5 to 11 years of age; children with cerebral palsy (CP; n = 10), children with spina bifida and hydrocephalus (SBH; n = 10) and children with pragmatic language impairment (PLI; n = 10), in order to explore pragmatic abilities within each group. A range of…

The primary goal of this study was to examine the relationship between deaf and hard-of-hearing students' learning style preferences and compare them to their nondeaf peers. Specifically, this study used 90 students throughout western Washington State, 45 per group. Quantitative data were collected using the 104-question survey Learning Style…

The General Ability Index (GAI) is a composite ability score for the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV) that minimizes the impact of tasks involving working memory and processing speed. The goal of the current study was to compare the degree to which the Full Scale IQ (FSIQ) and the GAI predict academic achievement…

The mnemonic model of posttraumatic stress disorder (PTSD) proposed by D. C. Rubin, D. Berntsen, and M. K. Bohni presents some provocative and potentially insightful ideas about this mental disorder. D. C. Rubin et al. suggested that PTSD is caused and maintained through a "pathogenic memory" (D. C. Rubin et al., 2008, p. 985) of a negative event…

Background: Since individuals with intellectual disabilities are often the only witnesses to alleged crimes, it is important to know their capacity to provide eyewitness testimony. Methods: Twenty-two participants with intellectual disabilities and 23 comparison group participants had their photographs taken by a confederate. One to two weeks…

Although an important role has been ascribed to working-memory capacity in reading comprehension, little consensus exists on its conceptualization, operationalization, and measurement except for its recognition as a limited-capacity processing and storage system. One specific problem in the measurement of working memory comes from researchers' use…

Background: This investigation addresses whether there are differences in the form and content of autobiographical memory recall as a function of maltreatment, and examines the roles of self-system functioning and psychopathology in autobiographical memory processes. Methods: Autobiographical memory for positive and negative nontraumatic events…

The nature of the comorbidity between Attention-Deficit/Hyperactivity Disorder (ADHD) and Reading Disability (RD) was examined using a double dissociation design. Children were between 8 and 12 years of age and entered into four groups: ADHD only (n = 24), ADHD+RD (n = 29), RD only (n = 41) and normal controls (n = 26). In total, 120 children…

Background: It is recognized that individuals with Down's syndrome have a specific deficit in verbal short-term memory. On the other hand, non-verbal short-term memory seems to be preserved or even be a strong point for these persons. Nevertheless, the extent and specificity of the deficit must be determined. To do so, we carried out a research…

We tested whether memory deficits in temporal lobe epilepsy (TLE) are better described by a single- or dual-store memory model. To this aim, we analyzed the influence of TLE and proactive interference (PI) on immediate and 24-h long-term recency effects during face recognition in 16 healthy participants and 18 right and 21 left non-surgical TLE…

In this article, the first explicit, theory-based comparison of 2-choice and go/no-go variants of 3 experimental tasks is presented. Prior research has questioned whether the underlying core-information processing is different for the 2 variants of a task or whether they differ mostly in response demands. The authors examined 4 different diffusion…
