Typical And Atypical Development Of Compensation To Altered Auditory Feedback, Caitlin E. Coughler
Electronic Thesis and Dissertation Repository
Auditory feedback, how we hear ourselves speak, plays an important role in the acquisition and maintenance of fluent speech. Although there is wide acceptance of the importance of auditory feedback control throughout development, little is known about how this develops or how the reliance on auditory feedback control may shift compared to other elements of speech motor control. This dissertation aimed to improve our understanding of the development of auditory feedback control and speech motor control in typically developing children and pediatric clinical populations through the exploration of responses to altered auditory feedback. In altered auditory feedback paradigms, small, often …

Hypophonia (low speech intensity) has been found to be the most common speech symptom experienced by individuals with Parkinson’s disease (PD). Previous research suggests that, in the PD population, there may be abnormal integration of sensory information for motor production of speech intensity. In the current study, auditory feedback was systematically manipulated during sensorimotor conditions that are known to modulate speech intensity in everyday contexts. Twenty-six individuals with PD and twenty-four neurologically healthy controls were asked to complete the following tasks: converse with the experimenter with varying distances between the participant and listener (near and far distances), vowel prolongation, read …
