Fernandez, Thalia; Harmony, Thalia; Mendoza, Omar; Lopez-Alanis, Paula; Marroquin, Jose Luis; Otero, Gloria; Ricardo-Garcell, Josefina – Brain and Cognition, 2012
Learning disabilities (LD) are one of the most frequent problems for elementary school-aged children. In this paper, event-related EEG oscillations to semantically related and unrelated pairs of words were studied in a group of 18 children with LD not otherwise specified (LD-NOS) and in 16 children with normal academic achievement. We propose that…

Hanna, Gregory L.; Carrasco, Melisa; Harbin, Shannon M.; Nienhuis, Jenna K.; LaRosa, Christina E.; Chen, Poyu; Fitzgerald, Kate D.; Gehring, William J. – Journal of the American Academy of Child & Adolescent Psychiatry, 2012
Objective: The error-related negativity (ERN) is a negative deflection in the event-related potential after an incorrect response, which is often increased in patients with obsessive-compulsive disorder (OCD). However, the relation of the ERN to comorbid tic disorders has not been examined in patients with OCD. This study compared ERN amplitudes…

Achim, Andre; Marquis, Alexandra – Clinical Linguistics & Phonetics, 2011
Studies of bilingualism sometimes require healthy subjects to be assessed for proficiency at auditory sentence processing in their second language (L2). The Syntactic Comprehension task of the Bilingual Aphasia Test could satisfy this need. For ease and uniformity of application, we automated its English (Paradis, M., Libben, G., and Hummel, K.…

Ash, Sharon; McMillan, Corey; Gunawardena, Delani; Avants, Brian; Morgan, Brianna; Khan, Alea; Moore, Peachie; Gee, James; Grossman, Murray – Brain and Language, 2010
The nature and frequency of speech production errors in neurodegenerative disease have not previously been precisely quantified. In the present study, 16 patients with a progressive form of non-fluent aphasia (PNFA) were asked to tell a story from a wordless children's picture book. Errors in production were classified as either phonemic,…

Pontifex, Matthew B.; O'Connor, Phillip M.; Broglio, Steven P.; Hillman, Charles H. – Neuropsychologia, 2009
The influence of multiple mild traumatic brain injuries (mTBIs) on neuroelectric and task performance indices of the cognitive control of action monitoring was assessed in individuals with and without a history of concussion. Participants completed a standard clinical neurocognitive assessment and the error-related negativity of the…

Wolf, Robert Christian; Sambataro, Fabio; Lohr, Christina; Steinbrink, Claudia; Martin, Claudia; Vasic, Nenad – Neuropsychologia, 2010
Behavioral and functional neuroimaging studies indicate deficits in verbal working memory (WM) and frontoparietal dysfunction in individuals with dyslexia. Additionally, structural brain abnormalities in dyslexics suggest a dysconnectivity of brain regions associated with phonological processing. However, little is known about the functional…

Bartle-Meyer, Carly J.; Murdoch, Bruce E.; Goozee, Justine V. – Clinical Linguistics & Phonetics, 2009
The current study aimed to provide a comprehensive analysis of linguopalatal contact patterns in participants with acquired apraxia of speech (AOS). Tongue-to-palate contacts were recorded for three participants with AOS during consonant singletons and consonant clusters using the Reading Electropalatograph (EPG3) system. Amount and pattern of…
