Child Health Professionals And Their Role In Detecting Speech And Language Impairments: Perceptions And Current Practices, Carissa A H Johnson
Child Health Professionals And Their Role In Detecting Speech And Language Impairments: Perceptions And Current Practices, Carissa A H Johnson
Master's Theses
Speech-language impairments are one of the most common conditions of childhood and affect roughly 5-8% of preschoolers and 11-20% of kindergarteners. If left untreated, speech-language impairments persist in 40-60% of children under five years of age and are strong predictors of school failure. Despite strong evidence that supports early intervention, as many as 90% of eligible children are not receiving appropriate services. This qualitative research study investigated child health professionals’ current knowledge, perceptions, and practices for screening and referring children with possible speech and language impairments. Data were gathered primarily through participant interviews and scenario questions. The data were then …
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
Electronic Thesis and Dissertation Repository
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 …
Infants' Sensitivity To Fine Durational Cues In Speech Perception, Alyssa K. Kuiack
Infants' Sensitivity To Fine Durational Cues In Speech Perception, Alyssa K. Kuiack
Undergraduate Honours Theses
Previous research has indicated that infants as young as 3 days of age show sensitivity to prosodic stress patterns and can use this information to distinguish word boundaries (Christophe et al., 1994). Older infants have also exhibited an ability to use prosodic stress patterns to segment streams of speech (Echols et al., 1997) and have shown a preference for samples of speech with the patterns of prosody displayed by their native language versus the prosodic patterns typical of other non-native languages (Werker & Tees 1984, Juscyzk et al. 1993). Adults have demonstrated the ability of language discrimination based strictly on …
