Dissertations, Theses, and Capstone Projects

ABSTRACT

This paper is an experimental study on how perceptions about a speaker’s age and ethnicity may influence whether listeners perceive the THOUGHT / LOT distinction. The macro-categories of age and ethnicity have been found to correlate with the lowering of raised THOUGHT (Wong 2012, Becker 2010) and the favoring of the merged vowels in perception (Haddican et al. 2016). This thesis examines whether images of faces associated with different age and ethnicity categories condition perception of auditory stimuli as belonging to either the LOT or THOUGHT class. This thesis builds on previous results suggesting that non-linguistic information influences speech …

Testing The Perceptual Magnet Effect In Monolinguals And Bilinguals, Michael C. Stern

Dissertations, Theses, and Capstone Projects

Previous research has demonstrated an apparent warping of the perceptual space whereby the best exemplars or ‘prototypes’ of speech sound categories minimize the perceptual distance between themselves and neighboring stimuli in the same category. This phenomenon has been termed the ‘perceptual magnet effect’ (PME). The present study extends work on the PME to a speech sound category previously unstudied in this paradigm (American English /æ/), and to bilingual speech sound representation and perception. American English monolinguals and Turkish-English bilinguals completed identification tasks, category goodness rating tasks, and same-different discrimination tasks with synthesized vowel sounds from the American English /æ/ category—not …
