Graduate student Michael Obiri-Yeboah was awarded a $43,000 Mellon/ACLS Dissertation Completion Fellowship for 2020-21 for his dissertation on the phonetics and phonology of Gua. This is a very prestigious and highly competitive fellowship: only 6% of the applications are funded. Congratulations, Michael!
Graduate student Yaqian Huang just published a paper entitled “Different attributes of creaky voice distinctly affect Mandarin tonal perception” in The Journal of the Acoustical Society of America, 147(3): 1441-1458. The abstract is below. Congratulations, Yaqian!
Abstract. Previous work has shown mixed findings concerning the role of voice quality cues in Mandarin tones, with some studies showing that creak improves identification. This study tests the linguistic importance of acoustic properties of creak for Mandarin tone perception. Mandarin speakers identified tones with four resynthesized creak manipulations: low spectral tilt, irregular F0, period doubling, and extra-low F0. Two experiments with three conditions were conducted. In Experiment 1, the manipulations were confined to a portion of the stimuli’s duration; in Experiment 2 the creak manipulations were modified and lengthened throughout the stimuli, and in a second condition, noise was incorporated to weaken F0 cues. Listeners remained most sensitive to extra-low F0, which affected identification of the four tones differently: it improved the identification accuracy of Tone 3 and hindered that of Tones 1 and 4. Irregular F0 consistently hindered T1 identification. The effects of irregular F0, period doubling, and low spectral tilt emerged in Experiment 2, where F0 cues were less robust and creak cues were stronger. Thus, low F0 is the most prominent cue used in Mandarin tone identification, but other voice quality cues become more salient to listeners when the F0 cues are less retrievable.
Graduate student Qi Cheng, a Ph.D candidate in our department and a member of Rachel Mayberry Lab for Multimodal Language Development, was recently awarded a National Science Foundation Linguistics Program – Doctoral Dissertation Research Improvement Grant (#1917922) for her dissertation work. Her research examines the biological foundations of human language with a focus on early language experience, linking observations from language learning, processing, and the brain network. Supported by the grant, she is currently conducting two psycholinguistic experiments to explore sentence processing strategies used by deaf late signers who suffered from early language deprivation. She presented the preliminary findings at CUNY Conference on Sentence Processing and Theoretical Issues in Signed Language Research (TISLR). She recently published a paper on the neural language pathways of deaf signers with and without early language on Frontiers in Human Neuroscience.

Graduate student Nina Semushina, a PhD candidate in our department and a member of Rachel Mayberry Lab for Multimodal Language Development, was recently awarded a National Science Foundation Doctoral Dissertation Research Improvement Grant (Ling-DDRI) for the project “The development of numerical cognition and linguistic number use: Insights from sign languages”. The goal of the project is to study the effects of language deprivation on the acquisition of numeracy and linguistic number use in American sign language, taking into account some modality-specific properties of numeral systems and plural morphology in sign languages.
Our third year graduate student Tory Sampson was awarded the best student stage presentation at the 13th triennial Theoretical Issues in Sign Language Research (TISLR). Her presentation focused on the copular cycle in American Sign Language (ASL) with the sign, labeled as ‘SELF’. In this presentation, Tory presented three stages in the evolution of SELF – as a demonstrative pronoun in 1850’s French Sign Language (LSF – a predecessor of ASL), as a personal pronoun in 1910’s ASL, and finally as a copula in modern ASL. She also presented the ambiguous syntactic contexts that provided for the reinterpretation and subsequent grammaticalization of SELF. A video of her presentation can be found here.
