TLDR
A cluster analysis procedure was used to identify subgroups of children who manifested specific learning disabilities in reading (SLD/R) in terms of performance on a battery of eight language and perceptual tests, finding some significant differences in measures of oral reading and reading comprehension skills.Abstract:
A cluster analysis procedure was used to identify subgroups of children who manifested specific learning disabilities in reading (SLD/R) in terms of performance on a battery of eight language and perceptual tests. Subjects included a group of 100 SLD/R children and 50 normal readers (NR). Six SLD/R subgroups were identified. All subgroups were both significantly different from one another as well as significantly different from the NR group's performance on the diagnostic battery. In addition, some significant differences were found among the six subgroups on measures of oral reading and reading comprehension skills. These results were compared with those of previous studies, none of which employed samples of the SLD/R youngsters identified in public schools. Results also were examined for their implications for a more precise match between the SLD/R learner characteristics and type of teaching method or material.read more

The working brain (an introduction to neuropsychology)
TL;DR: Clinical Neurosurgery includes excellent clinical reviews but the two recent volumes include also a section of seminars on fundamental research-in volume 18 on coma and sleep, and in volume 19 on basic mechanisms of memory, which is a significant contribution to the literature on head injury.

Cognitive profiling and preliminary subtyping in Chinese developmental dyslexia.
TL;DR: It is suggested that orthographic and rapid naming deficits in Chinese dyslexic children might pose an interrelated problem in developing orthographic knowledge and representation, and orthographic-related difficulties may be the crux of the problem in Chinese developmental dyslexia.

Classification of teachers’ interaction behaviors in early childhood classrooms☆
TL;DR: McWilliam et al. as discussed by the authors investigated patterns of teachers' interaction behaviors in early childhood classrooms and identified four homogenous interaction clusters using cluster analysis techniques, including high ratings on elaborating and low ratings on redirecting behaviors.

Subtypes of Developmental Coordination Disorder
TL;DR: In this article, the authors investigated whether a group of 80 children with developmental coordination disorder (DCD) could be classified into subtypes based on their performances on six perceptuo-motor tasks.
