Dyslexia Beyond The Word: An Ecological Study Of Specific Reading Disorder, Benjamin T. Carter
Dyslexia Beyond The Word: An Ecological Study Of Specific Reading Disorder, Benjamin T. Carter
Theses and Dissertations
This dissertation discusses the effects of dyslexia on reading behavior and cognition. It does so by first outlining the overall incidence of dyslexia, providing current definitions, giving a history of scientific inquiry and discussing relevant contemporary research. Thirteen different analyses are then discussed (ten a priori and three post-hoc). Individuals with dyslexia were found to have increased fixation duration, first run dwell time, total dwell time, and refixation probability. The dyslexia group was also highly sensitive to lexical predictability. Within the reading network, the BOLD response was depressed in dyslexia during reading in the following regions: the left medial and …
Speech Perception Of Global Acoustic Structure In Children With Speech Delay, With And Without Dyslexia, Mikayla Nicole Madsen
Speech Perception Of Global Acoustic Structure In Children With Speech Delay, With And Without Dyslexia, Mikayla Nicole Madsen
Theses and Dissertations
Children with speech delay (SD) have underlying deficits in speech perception that may be related to reading skill. Children with SD and children with dyslexia have previously shown deficits for distinct perceptual characteristics, including segmental acoustic structure and global acoustic structure. In this study, 35 children (ages 7-9 years) with SD, SD + dyslexia, and/or typically developing were presented with a vocoded speech recognition task to investigate their perception of global acoustic speech structure. Findings revealed no differences in vocoded speech recognition between groups, regardless of SD or dyslexia status. These findings suggest that in children with SD, co-occurring dyslexia …
