This study investigated the word reading and listening comprehension difficulties of fourth-grade students with significant reading comprehension deficits and the cognitive difficulties that underlie these weaknesses. Latent profile analysis was used to classify a sample of fourth-grade students (n = 446) who scored below the 16th percentile on a…

How prevalent is dyslexia? A definitive answer to this question has been elusive because of the continuous distribution of reading performance and predictors of dyslexia and because of the heterogeneous nature of samples of poor readers. Samples of poor readers are a mixture of individuals whose reading is consistent with or expected based on…

This study investigated the presence of word reading difficulties in a sample of students in Grades 1-4 (n = 357) identified with language and reading comprehension difficulties. This study also examined whether distinct word reading and listening comprehension profiles emerged within this sample and the extent to which these groups varied in…

Cognitive skill differences that are apparent early in pre-kindergarten (pre-K) might provide predictive insights into risk for learning difficulties at school entry, particularly around early markers of risk for comorbid difficulties in early math and literacy. Domain-specific abilities (approximate number system or ANS acuity, phonological…

Relationships between early literacy measures (i.e., curriculum-based measurement) and advanced literacy measures (i.e., reading comprehension) were examined in young children with autism spectrum disorders (ASDs). Participants in this study were 167 children between the ages of 4 and 7 years (M = 5 years 8 months), who were assessed at 2 time…

In the current study, we investigated the effects of an instructional package (i.e., response prompting, sentence frames) on sentence writing for three middle school participants (ages 12-13) with moderate to severe disabilities. We employed a multiple probe across behaviors design to evaluate the efficacy of the intervention package and also used…

Students with mild intellectual disability generally garner less individual attention in research, as they are often aggregated with students with moderate and severe intellectual disability or students with other high incidence disabilities. This study used the National Longitudinal Transition Study-2 (NLTS2) to look at the personal…

The authors used data from a large, national sample to examine the interaction of various literacy measures among young children with disabilities. Using structural equation modeling, they examined the relationships among measures of phonemic awareness, decoding, vocabulary, and reading comprehension. Child and family factors, including sex,…

Research examining neuropsychological profiles of girls with Asperger's disorder (AD) is sparse. In this study, we sought to characterize neurocognitive profiles of girls with AD compared to girls with learning disabilities (LD). Two groups of school-age girls referred for neuropsychological assessment participated in the study. A total of 23…

Background: Clinic and community-based epidemiological studies have shown an association between child psychopathology and language impairment. The demands on language for social and academic adjustment shift dramatically during adolescence and the ability to understand the nonliteral meaning in language represented by higher order language…

The present study evaluated the stability of math learning difficulties over a 2-year period and investigated several factors that might influence this stability (categorical vs. continuous change, liberal vs. conservative cut point, broad vs. specific math assessment); the prediction of math performance over time and by performance level was also…

The purpose of this study was to determine the prevalence of four types of language disorders among public school students (N = 152) classified as Emotional Disturbance (ED). We also examined the association of the types of language disorders experienced by these students with specific learning disabilities and clinical levels of specific types of…
