Emotional and Behavioral Correlates of Persisting Specific Learning Disabilities in Written Language during Middle Childhood and Early Adolescence.

Parents completed the Behavior Assessment System for Children-Second Edition Parent Report Scale (BASC2-PRS) while their children (94 boys, 61 girls; M=11 years-11 months) were given tests. Evidence-based profiles of multiple test scores and history (emergence and persistence) were used to assign to groups without specific learning disabilities in written language (SLDs-WL) (n= 42 control) or with SLDs-WL: (n=29 dysgraphia, n=65 dyslexia, or n=19 oral and written language learning disability [OWL LD]). Parent ratings fell in the clinical or at risk ranges for some individuals in all groups, but mean BASC2-PRS ratings showed nine significant main effects for group (n=4): Behavioral Symptoms Index, Internalizing Problems Composite, Adaptive Skills Composite, two Clinical Scales (Atypicality and Attention Problems), and four Adaptive Scales (Adaptability, Activities of Daily Living, Leadership, and Functional Communication). Each SLDs-WL group differed significantly from the control group on these nine ratings, except dysgraphia on Atypicality and dyslexia on Adaptive Composite, Adaptability, and Leadership; and each correlated with one or more hallmark impairments associated with a specific SLD-WL. In an fMRI study (without OWL LD), the dysgraphia and dyslexia groups, but not control group, showed connectivity with amygdala; BASC2 PRS Internalizing Problems Composite (internal stress) correlated with amygdala connectivity from two cortical regions involved in written word processing and production for all groups (N=40). Applications to assessing emotional and behavioral correlates of SLDs-WL for educational services and future research are discussed.

Online Writing Processes in Translating Cognition into Language and Transcribing Written Language by Stylus and Keyboard in Upper Elementary and Middle School Students With Persisting Dysgraphia or Dyslexia.

Participants in this study completed an on-line experiment in which they wrote essays by stylus or keyboard. Three translation measures (length of language burst, length of pauses, and rate of pausing) and four transcription measures (total words, total time, words/minute, and percent spelling errors) for composition were analyzed for two research aims. Research Aim 1 addressed whether upper elementary and middle school students with carefully diagnosed transcription disabilities (dysgraphia with impaired handwriting, n=18, or dyslexia with impaired spelling, n=20) showed significant differences from pretest to posttest, across modes of transcription (stylus or keyboard), and between diagnostic groups. Results showed significant (a) change after intervention (18 computerized lessons with learning activities in letter formation/selection, spelling, and composing) in length of pauses, total time, and words per minute; (b) mode effects (fewer words and less time by stylus; fewer pauses per minute by keyboard); and (c) interactions with diagnostic group in response to intervention on some measures. Research Aim 2 addressed whether following intervention each of the diagnostic groups performed comparably to a typical control group (n=15) in the same on-line experiment. Results showed (a) comparable performance of the dysgraphia and control groups on all keyboarding tasks but differences on two stylus measures; and (b) lack of comparable performance of the dyslexia and control groups on two stylus measures (total words and percent spelling errors) and the four keyboarding tasks related to transcription. Implications for assistive technology and writing instruction for dysgraphia and dyslexia are discussed.

Effects of transcription ability and transcription mode on translation:: Evidence from written compositions, language bursts and pauses when students in grades 4 to 9, with and without persisting dyslexia or dysgraphia, compose by pen or by keyboard.

This study explored the effects of transcription on translation products and processes of adolescent students in grades 4 to 9 with and without persisting specific language disabilities in written language (SLDs-WL). To operationalize transcription ability (handwriting and spelling) and transcription mode (by pen on digital tablet or by standard US keyboard), diagnostic groups contrasting in patterns of transcription ability were compared while composing autobiographical (personal) narratives by handwriting or by keyboarding: Typically developing students (n=15), students with dyslexia (impaired word reading and spelling, n=20), and students with dysgraphia (impaired handwriting, n=19). They were compared on seven outcomes: total words composed, total composing time, words per minute, percent of spelling errors, average length of pauses, average number of pauses per minute, and average length of language bursts. They were also compared on automaticity of transcription modes-writing the alphabet from memory by handwriting or keyboarding (they could look at keys). Mixed ANOVAs yielded main effects for diagnostic group on percent of spelling errors,, words per minute, and length of language burst. Main effects for transcription modes were found for automaticity of writing modes, total words composed, words per minute, and length of language bursts; there were no significant interactions. Regardless of mode, the dyslexia group had more spelling errors, showed a slower rate of composing, and produced shorter language bursts than the typical group. The total number of words, total time composing, words composed per minute, and pauses per minute were greater for keyboarding than handwriting, but length of language bursts was greater for handwriting. Implications of these results for conceptual models of composing and educational assessment practices are discussed.

Understanding Interest and Self-Efficacy in the Reading and Writing of Students with Persisting Specific Learning Disabilities during Middle Childhood and Early Adolescence.

Three methodological approaches were applied to understand the role of interest and self-efficacy in reading and/or writing in students without and with persisting specific learning disabilities (SLDs] in literacy. For each approach students in grades 4 to 9 completed a survey in which they rated 10 reading items and 10 writing items on a Scale 1 to 5; all items were the same but domain varied. The first approach applied Principal Component Analysis with Varimax Rotation to a sample that varied in specific kinds of literacy achievement. The second approach applied bidirectional multiple regressions in a sample of students with diagnosed SLDs-WL to (a) predict literacy achievement from ratings on interest and self-efficacy survey items; and (b) predict ratings on interest and self-efficacy survey items from literacy achievement. The third approach correlated ratings on the surveys with BOLD activation on an fMRI word reading/spelling task in a brain region associated with approach/avoidance and affect in a sample with diagnosed SLDs-WL. The first approach identified two components for the reading items (each correlated differently with reading skills) and two components for the writing items (each correlated differently with writing skills), but the components were not the same for both domains. Multiple regressions supported predicting interest and self-efficacy ratings from current reading achievement, rather than predicting reading achievement from interest and self-efficacy ratings, but also bidirectional relationships between interest or self-efficacy in writing and writing achievement. The third approach found negative correlations with amygdala connectivity for 2 reading items, but 5 positive and 2 negative correlations with amygdala connectivity for writing items; negative correlations may reflect avoidance and positive correlations approach. Collectively results show the relevance and domain-specificity of interest and self-efficacy in reading and writing for students with persisting SLDs in literacy.

Relationships between language input and letter output modes in writing notes and summaries for students in grades 4 to 9 with persisting writing disabilities.

This study in programmatic research on technology-supported instruction first identified, through pretesting using evidence-based criteria, students with persisting specific learning disabilities (SLDs) in written language during middle childhood (grades 4-6) and early adolescence (grades 7-9). Participants then completed computerized writing instruction and posttesting. The 12 computer lessons varied output modes (letter production by stylus alternating with hunt and peck keyboarding versus by pencil with grooves alternating with touch typing on keyboard), input (read or heard source material), and task (notes or summaries). Posttesting and coded notes and summaries showed the effectiveness of computerized writing instruction on both writing tasks for multiple modes of language input and letter production output for improving letter production and related writing skills.
