Familial History of Reading Difficulty Is Associated with Diffused Bilateral Brain Activation during Reading and Greater Association with Visual Attention Abilities
Peer reviewed Peer reviewed
Direct linkDirect link
Horowitz-Kraus, Tzipi – Annals of Dyslexia, 2017
Reading difficulty (RD; or dyslexia) is a heritable condition characterized by slow, inaccurate reading accompanied by executive dysfunction, specifically with respect to visual attention. The current study was designed to examine the effect of familial history of RD on the relationship between reading and visual attention abilities in children…

Altered Neural Circuits Accompany Lower Performance during Narrative Comprehension in Children with Reading Difficulties: An fMRI Study
Peer reviewed Peer reviewed
Direct linkDirect link
Horowitz-Kraus, Tzipi; Buck, Catherine; Dorrmann, Dana – Annals of Dyslexia, 2016
Narrative comprehension is a linguistic ability that is foundational for future reading ability. The aim of the current study was to examine the neural circuitry of children with reading difficulties (RD) compared to typical readers during a narrative-comprehension task. We hypothesized that due to deficient executive functions, which support…

Examining the Relationship between Home Literacy Environment and Neural Correlates of Phonological Processing in Beginning Readers with and without a Familial Risk for Dyslexia: An fMRI Study
Peer reviewed Peer reviewed
Direct linkDirect link
Powers, Sara J.; Wang, Yingying; Beach, Sara D.; Sideridis, Georgios D.; Gaab, Nadine – Annals of Dyslexia, 2016
Developmental dyslexia is a language-based learning disability characterized by persistent difficulty in learning to read. While an understanding of genetic contributions is emerging, the ways the environment affects brain functioning in children with developmental dyslexia are poorly understood. A relationship between the home literacy…

An fMRI Study of Multimodal Semantic and Phonological Processing in Reading Disabled Adolescents
Peer reviewed Peer reviewed
Direct linkDirect link
Landi, Nicole; Mencl, W. Einar; Frost, Stephen J.; Sandak, Rebecca; Pugh, Kenneth R. – Annals of Dyslexia, 2010
Using functional magnetic resonance imaging, we investigated multimodal (visual and auditory) semantic and unimodal (visual only) phonological processing in reading disabled (RD) adolescents and non-impaired (NI) control participants. We found reduced activation for RD relative to NI in a number of left-hemisphere reading-related areas across all…

Phonological Awareness Predicts Activation Patterns for Print and Speech
Peer reviewed Peer reviewed

Frost, Stephen J.; Landi, Nicole; Mencl, W. Einar; Sandak, Rebecca; Fulbright, Robert K.; Tejada, Eleanor T.; Jacobsen, Leslie; Grigorenko, Elena L.; Constable, R. Todd; Pugh, Kenneth R. – Annals of Dyslexia, 2009
Using fMRI, we explored the relationship between phonological awareness (PA), a measure of metaphonological knowledge of the segmental structure of speech, and brain activation patterns during processing of print and speech in young readers from 6 to 10 years of age. Behavioral measures of PA were positively correlated with activation levels for…

Differentiating the Neural Response to Intervention in Children with Developmental Dyslexia
Peer reviewed Peer reviewed
Direct linkDirect link
Odegard, Timothy N.; Ring, Jeremiah; Smith, Stephanie; Biggan, John; Black, Jeff – Annals of Dyslexia, 2008
Developmental dyslexia is associated with functional abnormalities within reading areas of the brain. For some children diagnosed with dyslexia, phonologically based remediation programs appear to rehabilitate brain function in key reading areas (Shaywitz et al., Biological Psychiatry 55: 101-110, 2004; Simos et al., Neuroscience 58: 1203-1213,…
