The Impact Of Statistical Learning On Language And Social Competency In Asd And Adhd: Divergent Findings, Kaitlyn M.A Parks

Statistical learning is a process that allows individuals to extract regularities from the environment and plays an important role in language acquisition, speech segmentation, and aspects of social behaviour. Little is known about the contribution of statistical learning impairments on Autism Spectrum Disorder (ASD) and Attention-Deficit/Hyperactivity Disorder (ADHD) related traits. The current study examined whether impairments in auditory and visual statistical learning are related to ASD and ADHD traits, language, and social competency. Decreased auditory, but not visual statistical learning abilities was related to increased autism traits and visual statistical learning and social competency abilities were mediated by language comprehension. …
Eyetracking Of Coarticulatory Cue Responses In Children And Adults, Alexandra M. Cross
Eyetracking Of Coarticulatory Cue Responses In Children And Adults, Alexandra M. Cross
Electronic Thesis and Dissertation Repository
Studies examining sensitivity to coarticulatory cues during spoken word recognition have typically examined children and adults separately. The present thesis compared sensitivity to coarticulatory cues in school-aged children and adults using eyetracking. Children and adults listened to words containing congruent and incongruent coarticulatory cues while looking at a two-picture display. Contrary to theories positing weakened attention to phonetic detail in children, we observed equal or greater sensitivity to coarticulatory cues in children compared to adults. This effect was related to predictors of reading and language proficiency, and was also modulated by phoneme contrasts such that children were overly sensitive to …
The Influence Of Proficiency And Age Of Acquisition On Second Language Processing: An Fmri Study Of Mandarin-English Bilinguals, Emily S. Nichols
The Influence Of Proficiency And Age Of Acquisition On Second Language Processing: An Fmri Study Of Mandarin-English Bilinguals, Emily S. Nichols
Electronic Thesis and Dissertation Repository
Research investigating the neural correlates of second language (L2) processing has usually studied age of acquisition (AoA) and proficiency separately. Presently, we examined both in parallel, treated as continuous variables. We used fMRI to study neural activity for L2 processing in adult native Mandarin speakers who are L2 English speakers. Behavioral measures of language proficiency and AoA were obtained from subjects prior to performing a picture-word matching task during an fMRI scan. Brain activity during L2 English processing was shown to be independently affected by AoA and proficiency; activity in left superior temporal gyrus and right parahippocampal gyrus was modulated …
