Mathematical Modeling Of Stress Management Via Decisional Control, Matthew J. Shanahan
Mathematical Modeling Of Stress Management Via Decisional Control, Matthew J. Shanahan
Electronic Thesis and Dissertation Repository
Engaging the environment through reason, humankind evaluates information, compares it to a standard of desirability, and selects the best option available. Stress is theorized to arise from the perception of survival-related demands on an organism. Cognitive efforts are no mere intellectual exercise when ontologically backed by survival-relevant reward or punishment. This dissertation examines the stressful impact, and countervailing peaceful impact, of environmental demands on cognitive efforts and of successful cognitive efforts on a person’s day-to-day environment, through mathematical modeling of ‘decisional control’. A modeling approach to clinical considerations is introduced in the first paper, “Clinical Mathematical Psychology”. A general exposition …
Prosody: An Important Cue To Word Learning, Monica Dasilva
Prosody: An Important Cue To Word Learning, Monica Dasilva
Electronic Thesis and Dissertation Repository
Infants rely on cues from their environment during language acquisition. Prosodic features of words are one such cue and involve changes in stress and rhythmic patterns within speech. Studies have examined prosody’s influence on word segmentation and have found it to be a useful cue for detecting word boundaries (Johnson & Seidl, 2009). What is less understood is how prosody helps infants form associations between novel labels and their referents during word learning. The present thesis investigated the influence of prosodic cues on word learning. The looking times were recorded of 13 infants (19-25 months) exposed to object-label pairings that …

The Coffee Shop Effect: Investigating The Relationship Between Ambient Noise And Cognitive Flexibility, Emily G. Nielsen
Electronic Thesis and Dissertation Repository
Cognitive flexibility is the ability to think diversely in order to solve problems and learn concepts. It has also been suggested that cognitive flexibility supports creativity. Research has demonstrated that creativity is enhanced by moderate volumes of ambient noise. This thesis sought to replicate and extend this line of research by investigating how noise affects cognitive flexibility. Study 1 assessed the effects of noise on three creativity tasks. Performance was found to be enhanced by ambient noise, particularly among those who listen to music while they study/work. Study 2 examined how noise affects performance on a category learning task designed …
Event-Related Potential Markers Of Perceptual And Conceptual Speech Processes In Patients With Disorders Of Consciousness., Stephen T. Beukema
Event-Related Potential Markers Of Perceptual And Conceptual Speech Processes In Patients With Disorders Of Consciousness., Stephen T. Beukema

Vegetative state (VS) and minimally conscious state (MCS) patients behaviorally demonstrate absent or fluctuating levels of awareness. Functional magnetic resonance imaging evidence of covert perceptual and semantic speech processing provides prognostic value for these patients. In this thesis, I examined the utility of high-density electroencephalography (EEG) in this regard. A contrast between event-related potentials (ERPs) elicited by primed and unprimed word pairs was used to isolate conceptual (semantic) processes, while ERPs elicited by signal-correlated noise were contrasted with those elicited by speech to isolate pre-semantic, perceptual aspects of speech processing. These ERP effects were found to be both temporally and …
