Changes In The Perception Of Stop Consonants Through Enhanced Cue Training As Reflected By Categorical Boundaries And Late Auditory Evoked Potentials, Clifford Anthony Franklin May 2004

Changes In The Perception Of Stop Consonants Through Enhanced Cue Training As Reflected By Categorical Boundaries And Late Auditory Evoked Potentials, Clifford Anthony Franklin

Doctoral Dissertations

Hearing-impaired listeners have difficulty in discriminating between voiced stop consonants. An important acoustic cue in this discrimination is the transition from the frequency of the consonant to the frequency of the vowel. The main purpose of this study was to investigate the effect of auditory training on the perception of the formant transition cue in the discrimination of the place of articulation of voiced stop consonants in synthetic CV stimuli of hearing-impaired listeners. Changes in perception were represented by behavioral and electrophysiological measures. Generalization effects after training and correlations between behavioral and electrophysiological measures were also measured.

Measures Of Auditory Inhibition In Female Smokers And Non-Smokers, Christopher Gray Clinard May 2004

Measures Of Auditory Inhibition In Female Smokers And Non-Smokers, Christopher Gray Clinard

Masters Theses

This study examined the chronic effects of cigarette smoking on auditory inhibition in normal-hearing female smokers and non-smokers. Nicotine is an acetylcholinomimetic drug that affects the central auditory nervous system. Physiologic measures were acoustic reflex threshold, click-evoked optoacoustic emission (CEOAE) amplitude, contralateral CEOAE suppression, and the auditory late latency response (LLR). The behavioral measure recorded was word recognition in the presence of a broadband masker at two signal-to-noise ratios (-5 and 0dB). Auditory responses were obtained from 13 smokers and 10 non-smokers. Results indicated that smoking does not have a significant effect on these auditory measures. However, tendencies observed for …
