Developmental dyscalculia (DD) is marked by specific deficits in processing numerical and mathematical information despite normal intelligence (IQ) and reading ability. We examined how brain circuits used by young children with DD to solve simple addition and subtraction problems differ from those used by typically developing (TD) children who…

Asperger syndrome (AS) and nonverbal learning disabilities (NLD) are developmental disorders in which linguistic ability is reported to be stronger than in disorders from which they must be distinguished for diagnosis. Children and adults with AS and NLD share pragmatic weaknesses, atypical social behaviours, and some cognitive features. To date,…

Visual and auditory verbal learning using a selective reminding format was studied in a mixed clinical sample of children with autism spectrum disorder (ASD) (n = 42), attention-deficit hyperactivity disorder (n = 83), velocardiofacial syndrome (n = 17) and neurotypicals (n = 38) using the Test of Memory and Learning to (1) more thoroughly…

Studies document various associated health risks for children with developmental disabilities (DDs). Further study is needed by disability type. Using the 2006-2010 National Health Interview Surveys, we assessed the prevalence of numerous medical conditions (e.g. asthma, frequent diarrhea/colitis, seizures), health care use measures (e.g. seeing a…

Previous research conducted by Nelson and Coorough (1994) found support for the statement that PhD programs were more research oriented, whereas doctorate of education (EdD) programs were more oriented to the educational practitioner. This previous study, however, had grouped all dissertations in education and had not looked at dissertations by…

Developmental dyscalculia (DD) still lacks a generally accepted definition. A major problem is that the cognitive component processes contributing to arithmetic performance are still poorly defined. By a reanalysis of our previous event-related brain potential (ERP) data (Soltesz et al., 2007) here our objective was to identify and compare…

Ordinality is--beyond numerical magnitude (i.e., quantity)--an important characteristic of the number system. There is converging empirical evidence that (intra)parietal brain regions mediate number magnitude processing. Furthermore, recent findings suggest that the human intraparietal sulcus (IPS) supports magnitude and ordinality in a…

This study describes the validity and the sensitivity and specificity of depression screening tools among adults with intellectual and disabilities (ID). Subjects (N = 75) were interviewed with the Beck Depression Inventory II (BDI-II) and the Glasgow Depression Scale for People with a Learning Disability (GDS-LD) and also completed a clinical…

Differences in comprehension, production, and appreciation of humor were explored among a total of 47 second and fourth graders, of whom 26 fourth graders had learning disabilities or developmental handicaps. Although children without disabilities comprehended cartoons better, no production differences were observed. (Author/DB)

"Words and Concepts" is a computer software program that focuses on building oral language skills related to vocabulary, comprehension, word relationships, and other concepts in six units--vocabulary, categorization, word identification by function, word association, concept of same, and concept of different. It can be used by adults and…

A study examined cognitive disorders and syntactical deficiencies in the inmate populations of federal penitentiaries in Canada. The focus of the study was on the relationship between language development and cognitive ability. During the study, a total of 240 inmates from prisons throughout Canada were given hour-long interviews in which they…

The patterns of cognitive play of 28 African-American and Euro-American preschool children with intellectual disabilities are reported. Fourteen children representing each group, matched on developmental age and family variables, were observed playing independently at home. The pattern of African-American children's play was more reflective of…
