Audiovisual Speech Processing: Implications For Speech Perception And Language Development, Ryan Andrew Cannistraci
Audiovisual Speech Processing: Implications For Speech Perception And Language Development, Ryan Andrew Cannistraci
Doctoral Dissertations
This dissertation aims to empirically assess the complex, multileveled relationships between audiovisual speech perception and early language development. The majority of extant language development research has justifiably focused on infants’ ability to learn language from auditory input, and indeed, infants are precocious auditory learners (Saffran & Kirkham, 2018). Complementary to auditory speech, however, are the necessarily redundant facial movements used to articulate speech. Outside of language development research, multimodal processing has been theorized to facilitate perceptual learning and cognitive development (Bahrick & Lickliter, 2000), but only a small number of empirical studies have investigated how audiovisual speech perception in infancy …

Representation Of Reward And Risk In The Brain’S Motor System: Studies In Adolescents And Adults, Xingjie Chen
Doctoral Dissertations
In the neuroscience of economic decision making, the brain’s motor system has been ascribed a role in implementing choice actions. However, recent work has revealed canonical motor signals much in advance of choice action, possibly indicating their role in evaluation of decision options. In the current dissertation, we applied multimodal neuroimaging combining EEG and fMRI and used a novel paradigm that temporally separated the evaluation phase from the action phase of a decision-making process to investigate the mechanisms through which the motor control system contributes to decision making. Additionally, we further examined the developmental changes during the two phases of …
