A comparison of reading strategies in genetic dyslexics and children with right and left brain deficits

The reading levels and reading strategies of 43 children with genetic dyslexia, right-hemisphere lesions/dysfunction, and left-hemisphere lesions/dysfunction were retrospectively compared. Age and IQ were comparable. Only children who had a verbal or performance IQ over 90 were included in the study. Although the genetic dyslexics had a significantly higher Full Scale IQ than the other two groups, their reading level was significantly lower. This suggests that a disturbance of the normal processes of neuronal migration during fetal development may have profound effects on specific cognitive processes, without affecting others. In contrast, 50 percent of the boys with left-hemisphere deficits were disabled readers. One-third of the boys with right-hemisphere deficits were also poor readers. With one exception, the girls, who had comparable deficits, were good readers. A comparison was made between the groups in terms of reading strategies and patterns of errors.     

The Best of the Recent Literature Focusing on the User

This will be my first time authoring this column, and I'm delighted to have the opportunity it presents to explore the intersection of library technology and public services. As the recent title of the 2008 Internet Librarian conference indicates, Beyond Library 2.0: User-Focused Tools and Technologies, the tide of what for several years has felt like library technology evangelism is turning. A focus on more effective tech-based development in libraries is underway, one that privileges the actual impact of services on patrons over our need to keep up with the proverbial Joneses. This is a natural correction—libraries experienced a sort of “tech bubble” as early adopters enthusiastically explored the promise of new Web-based communication methods and user-created tools. After several years of trial and error, many early adopters now find themselves adjusting expectations, considering overall scalability, and evaluating outcomes of their early experiments. Much can be learned from these experiences, and a wealth of evidence, conjecture, and rules of thumb can now assist librarians in any stage of technology development prevent duplication of effort (and error). With this in mind, I will attempt to make this column as practically oriented as possible. I will draw from the knowledge of those who have confronted the types of issues and pitfalls inherent to library innovation, and I will explore proven approaches that can help librarians in the public services develop more effective and user-centered technologies. At times I will invite guest authors to describe best practices developed at their own institutions and/or explore topics that carry broad implications for public service practitioners.     

Neurological impairment in maltreated children

The neurological competency of maltreated children was assessed by comparing physically abused children not known to have sustained serious head trauma, neglected children, and normally raised children from the same socioeconomic milieu. Each child underwent physical and neurological examinations including EEGs, supplemented by perceptual-motor tests devised to detect subtle evidence of neurological dysfunction. Obstetrical and developmental histories, as well as intelligence test protocols, were available. Blind ratings by a pediatric neurologist using all available information revealed significantly more impairment in the maltreated groups with more than 50% of the abused children in the moderate or severely impaired category. The complex relationship between the maltreating environment and neurological disorders in these populations is discussed including the need to routinely search for evidence of subtle neurological impairment when maltreatment is known or suspected.     

Phonological awareness training and remediation of analytic decoding deficits in a group of severe dyslexics

The goal of the present study was to evaluate the effectiveness of the Auditory Discrimination in Depth Program (ADD) in remediating the analytic decoding deficits of a group of severe dyslexics. A group of ten severely dyslexic students ranging in age from 93 to 154 months were treated in a clinic setting for 38 to 124 hours (average of 65 hours). Pre- and post-treatment testing was done with the Woodcock Reading Mastery Test and the Lindamood Auditory Conceptualization to assess changes in phonological awareness and analytic decoding skills. Results revealed statistically significant gains in phonological awareness and analytic decoding skills.     

Intensive remedial instruction for children with severe reading disabilities: immediate and long-term outcomes from two instructional approaches

Sixty children with severe reading disabilities were randomly assigned to two instructional programs that incorporated principles of effective instruction but differed in depth and extent of instruction in phonemic awareness and phonemic decoding skills. All children received 67.5 hours of one-to-one instruction in two 50-minute sessions per day for 8 weeks. Both instructional programs produced very large improvements in generalized reading skills that were stable over a 2-year follow-up period. When compared to the growth in broad reading ability that the participants made during their previous 16 months in learning disabilities resource rooms, their growth during the intervention produced effect sizes of 4.4 for one of the interventions and 3.9 for the other. Although the children's average scores on reading accuracy and comprehension were in the average range at the end of the follow-up period, measures of reading rate showed continued severe impairment for most of the children. Within 1 year following the intervention, 40% of the children were found to be no longer in need of special education services. The two methods of instruction were not differentially effective for children who entered the study with different levels of phonological ability, and the best overall predictors of long-term growth were resource room teacher ratings of attention/behavior, general verbal ability, and prior levels of component reading skills.
