The present study examined whether temporal processing (TP) is associated with reading of a non-alphabetic script, that is, Chinese. A total of 126 primary school-aged Chinese children from Taiwan (63 children with dyslexia) completed cross-modal, visual, and auditory temporal order judgment tasks and measures of Chinese reading and…

This study aimed to investigate the development of visual and auditory temporal processing among children with and without dyslexia and to examine the roles of temporal processing in reading and reading-related abilities. A total of 362 Chinese children in Grades 1-6 were recruited from Taiwan. Half of the children had dyslexia, and the other half…

Substantial evidence has established that individual differences in executive function (EF) in early childhood are uniquely predictive of children's academic readiness at school entry. The current study tested whether growth trajectories of EF across the early childhood period could be used to identify a subset of children who were at pronounced…

The majority of recent studies conclude that children's private speech development (private speech internalization) is related to and important for mathematical development and disabilities. It is far from clear, however, whether private speech internalization itself plays any causal role in the development of mathematical competence. The main…

Our goal was to investigate the growth of vocabulary and morphological awareness over time in the context of an intervention for kindergartners with different ability levels in these skills. Participants in this exploratory study were 108 children from schools serving socioeconomically disadvantaged neighborhoods. Results indicated that children…

Lervag and Hulme’s neuro-developmental theory and Wolf and Bowers’s double-deficit hypothesis were examined in this longitudinal study. A total of 130 children were tested in preschool and followed through fifth grade, when 84 remained in the study. During preschool and kindergarten the participants were given tests of end-sound discrimination…

We analyzed two nationally representative, longitudinal data sets of U.S. children to identify risk factors for persistent mathematics difficulties (PMD). Results indicated that children from low socioeconomic households are at elevated risk of PMD at 48 and 60 months of age, as are children with cognitive delays, identified developmental delays…

The extant literature on the social functioning of students with learning disabilities (LD) has indicated that whereas a majority belong to peer groups, a higher proportion are isolated and most have lower social status among peers in general than their typically achieving classmates. Although some work has examined these issues over short-term…

In response to a previous paper (EC 212 858) regarding the neurodevelopmental evidence for the basis of dyslexia, this paper offers corroborating evidence of neurological difference in dyslexic persons and stresses the need for more research on brain mechanisms in disorders of reading. (DB)

Opposing views regarding the connection between lead exposure and cognitive impairment are presented. C. B. Ernhart states that no study has yet proved that low-level lead exposure is detrimental to child development, while H. L. Needleman asserts that previous research studies have proven conclusively that such a connection exists. (CB)

The importance and relevance of longitudinal research in learning disabilities is addressed, including its value in verification of appropriate hypotheses concerning particular developmental patterns and debunking of misconceptions. Examples from various longitudinal studies are given. (DB)

Parents (N=100) of children (ages 9 to 13) with or without learning disabilities (LD) responded to a retrospective developmental survey. Parents reported that the children with LD had significantly more neurodevelopmental problems or delays across domains (e.g., language, motor, attention, social behavior) than normal achievers. A pattern of…

Investigation of the effects of age on the social perceptual ability of 30 learning disabled and 30 non-learning-disabled students (at ages 11, 14, and 17 years) indicated that, though social perceptual ability improved with age for both groups, the proportionate differences between the groups remained constant through age 17.

Issues and developmental considerations in outcome and treatment of head injury in children are considered. Focus is on appropriate assessment practices in the areas of psychoeducational development, motor and cognitive deficits, and neuropsychological deficits. (Author/DB)
