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…

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)

Development of reading speed in Italian children with dyslexia was estimated using individualized growth curves for 38 children with dyslexia tested longitudinally from 2nd-8th grade and compared with controls. Their reading speed development followed a linear trend of .3 syllables per second per grade, half the increment observed in controls.…

This longitudinal study followed the social development of 239 students (including 10 students with learning disabilities) from kindergarten through fifth grade. Repeated measurements of peer acceptance, reciprocal friendship, self-concept, and social skills found a substantial amount of instability in social competence components for the students…

This response to Vaughn and Hogan (EC 608 627), who reported a longitudinal study on the social competence of 10 children with learning disabilities, looks at problems in doing longitudinal research; the influence of environmental factors; and developmental issues. Possible interventions with children having consistent social problems are noted.…

A three-year study found that children with learning disabilities displayed a persistent pattern of maladaptive classroom behavior that distinguished them from average achievers and was associated with continued underachievement, especially for attention and conduct problem subtypes. The developmental relationship between learning disabilities,…
