Hemispheric object naming and interhemispheric transfer functions in reading disordered subjects

This study measured unilateral, tachistoscopic naming reaction times of normal and reading disordered children to objects representing two levels of picture vocabulary age. Results of an ANCOVA procedure on the latency data showed main effects for group and stimuli, but not visual field. The latency results suggested parallel, central picture naming operations for each group, with the reading disordered children evidencing significantly longer naming reaction times to each level of stimuli. Arc Sine transformed error data were submitted to an analysis of co-variance procedure and showed a significant stimuli x group interaction. Post hoc tests showed accelerated error rates following right hemispheric stimulation, suggesting anomalous interhemispheric transfer of visual images in the present group of reading disordered children. In addition, left hemispheric stimulations produced significantly more naming errors for the reading disordered subjects as compared to the normal children. Such findings may suggest that a group of higher-ordered processing operations may accompany reading disorders.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/43573/1/11145_2004_Article_BF00555367.pd

The Index Of Narrative Microstructure: A Clinical Tool For Analyzing School-Age Children's Narrative Performances

Purpose: This research was conducted to develop a clinical tool-the Index of Narrative Microstructure (INMIS)-that would parsimoniously account for important microstructural aspects of narrative production for school-age children. The study provides field test age- and grade-based INMIS values to aid clinicians in making normative judgments about microstructural aspects of pupils' narrative performance. Method: Narrative samples using a single-picture elicitation context were collected from 250 children age 5-12 years and then transcribed and segmented into T-units. A T-unit consists of a single main clause and any dependent constituents. The narrative transcripts were then coded and analyzed to document a comprehensive set of microstructural indices. Results: Factor analysis indicated that narrative microstructure consisted of 2 moderately related factors. The Productivity factor primarily comprised measures of word output, lexical diversity, and T-unit output. The Complexity factor comprised measures of syntactic organization, with mean length of T-units in words and proportion of complex T-units loading most strongly. Principal components analysis was used to provide a linear combination of 8 variables to approximate the 2 factors. Formulas for calculating a student's performance on the 2 factors using 8 narrative measures are provided. Conclusions: This study provided a method for professionals to calculate INMIS scores for narrative Productivity and Complexity for comparison against field test data for age (5- to 12-year-old) or grade (kindergarten to Grade 6) groupings. INMIS scores complement other tools in evaluating a child's narrative performance specifically and language abilities more generally.Communication Sciences and Disorder

Quality of the Literacy Environment in Inclusive Early Childhood Special Education ECSE Classrooms

The purpose of this study was to examine the quality of the literacy environment in inclusive early childhood special education (ECSE) classrooms (N = 54). The first aim was to describe the quality of the literacy environment in terms of structure (i.e., book materials and print/writing materials) and instruction (i.e., instructional support). The second aim was to examine the interrelationships among teacher and classroom characteristics and the quality of the literacy environment. Results showed that, on average, the quality of the structural literacy environment was low to moderate, and the quality of the instructional literacy environment was generally low. The number of children who were Dual Language Learners related to the quality of the structural literacy environment. The quality of the instructional literacy environment was positively associated with two teacher variables (teacher education and self-efficacy) and was negatively associated with one teacher variable (the number of language and literacy workshops attended). Implications are discussed

Relations between Home Literacy Environment, Child Characteristics, and Print Knowledge for Preschool Children with Language Impairment

To contribute to the modest body of work examining the home literacy environment (HLE) and emergent literacy outcomes for children with disabilities, this study addressed two aims: (a) to determine the unique contributions of the HLE on print knowledge of preschool children with language impairment (LI); and (b) to identify whether specific child characteristics (oral language ability, print interest) moderated these relations. The sample consisted of 119 preschool children with LI. HLE was conceptualized as frequency of storybook reading and literacy teaching during book reading. Frequency of storybook reading was a unique predictor of print knowledge, which is consistent with research on children with typical language. Literacy teaching did not predict print knowledge, which diverges from research on children with typical language. No interactions between the HLE and child characteristics were significant, but language ability and print interest play a role in understanding individual differences in literacy development

Phonological awareness emergence in preschool children with autism spectrum disorder

Background and aims Phonological awareness begins to develop during the preschool years and is a primary factor underlying later reading abilities. Previous research has found mixed results on the phonological awareness skills of children with autism spectrum disorders. Therefore, the purpose of the present study is to add to our understanding of phonological awareness in children with autism spectrum disorder by investigating residualized gains in phonological awareness skills over an academic year. Methods A total of 125 preschool (4- to 5-years old) children including 27 children with autism spectrum disorder, 28 children with language impairment, and 70 typically developing children were the focus of the present study. Participants in the current study represent a subset of participants from a larger study titled, Sit Together and Read. Children completed direct assessments in the beginning (fall) and end of school year (spring) on phonological awareness using the Test of Preschool Early Literacy. Results A one-way ANOVA compared the phonological awareness skills tasks (syllable/onset-rime, blending/elision, receptive/expressive) in the fall and the spring for each of the three groups (children with autism spectrum disorder, children with language impairment, children who are typically developing). In the fall and the spring, all of the analyses were found to be statistically significant. A Tukey HSD further indicated that children with autism spectrum disorder had significantly lower scores on all of the tasks at both time points compared to the typically developing peers. Children with autism spectrum disorder seem to make gains in phonological awareness tasks similarly to their typically developing peers for most of the phonological awareness tasks. Results from the final regression models indicated that children with autism spectrum disorder made gains similar to those of their typically developing peers for most phonological awareness tasks and that language skills predicted residualized gain for syllable, elision, and receptive tasks, as well as the total score when controlling for condition, IQ, and group status. Social skills were not a significant predictor for any of the tasks. Conclusions Three main findings emerged: (a) phonological awareness skills seem to be a deficit for children with autism spectrum disorder, (b) in general, autism status does not predict residualized gain in phonological awareness skills, and (c) oral language is a significant predictor of residualized gain in phonological awareness skills. Implication Early childhood educators should focus on providing high-quality instruction on phonological awareness for children with autism spectrum disorder and researchers should focus on investigating the effectiveness of phonological awareness interventions for children with autism spectrum disorder

Noun Phrase Elaboration in Children\u27s Spoken Stories

Purpose: One feature of literate language, noun phrase elaboration, was examined in the oral fictional narratives of school-aged children. Method: Two narratives were elicited from 5-, 8- and 11-year-old children, 1 in response to a picture sequence and 1 in response to a single picture. Noun phrases were categorized into 4 types. Results: Simple designating noun phrases were produced by all children at age 5, simple descriptive noun phrases by all children at age 8, and noun phrases with postmodification by all children at age 11. All noun phrase types were produced by more children in object than in subject position and in the single picture than in the picture sequence context. Conclusion: There are important developmental changes in noun phrase elaboration in the elementary school years as children learn to manage narrative contexts. Even within picture tasks, variations in visual depiction can affect the use of elaborated noun phrases (ENPs), with more descriptive language more likely to occur in narratives based on a single picture fantasy context than on a realistic picture sequence context. Performance expectations for types of ENPs within these contexts are provided. These findings will be useful to school clinicians in evaluating and working on narrative language within the elementary school period
