SUMMARY:Neural network mechanisms underlying individual differences in language learning success - Dr. Gangyi FENG\, The Chinese University of Hong Kong
DESCRIPTION:Human language learning differs significantly across individuals in the process and ultimate attainment. Although decades of research exploring the neural substrates of language learning have identified distinct and overlapping brain networks subserving learning of different components\, the neural mechanisms that drive the large interindividual differences in learning success are still far from being understood. In this talk\, I will introduce recent works from my group on neural mechanisms of language learning across multiple components (e.g.\, auditory and speech category learning\, word and grammar learning). With machine learning and predictive modeling techniques\, we have identified potential neuromarkers that showed robust predictive powers of individual learning success. Identifying the neuromarkers has direct implications for constructing contemporary cognitive neuroscience models of language learning and informing educational practice and clinical research. The neuromarkers and mechanisms derived from this line of work have the potential to be applied to predicting individual language improvement and outcomes for populations with language deficits and developmental delays. The neuromarkers and prediction techniques could be leveraged in designing individualized training and intervention paradigms that maximize learning efficacy and minimize individual differences in outcome. \n\n\n\nDate:\nOctober 20\, 2022\n\n\nTime:\n3:30 – 5:00 pm\n\n\nZoom meeting:\nhttps://hku.zoom.us/j/93808540621\n\n\nMeeting ID:\n938 0854 0621\n\n\n\n

SUMMARY:The Non-Coalescence of /h/ and Incomplete Neutralization in South Jeolla Korean - Dr. Seunghun LEE\, International Christian University & IIT Guwahati
DESCRIPTION:This talk presents articulatory and acoustic data in order to investigate the non-coalescence of /h/ in South Jeolla. Seoul Korean speakers produce /pap/ ‘rice’ followed by /hana/ ‘one’ as [pa.pha.na] with the coalescence of /p/ and /h/; this is called an aspiration merger. In South Jeolla Korean\, this merger may be blocked\, as in cases where speakers produce /pap + hana/ as [pa.ba.na]. Electroglottographic (EGG) data indicates the existence of two groups of South Jeolla speakers: one that merges the plosive and /h/ (the merger group)\, and the other with the canonical South Jeolla Korean pronunciation that does not merge the two consonants (the non-merger group). The production of non-coalesced lenis stops in the non-merger group is phonetically comparable with an underlying lenis stop produced by both of the groups. However\, in the non-merger group\, the open quotient (OQ) of a vowel following a non-coalesced lenis stop is higher (breathier) than that of an underlying lenis stop. Spectral tilt results display a similarly increased breathiness when the vowel follows a non-coalesced lenis stop. As for the non-merger group of South Jeolla\, we argue that speakers display incomplete neutralization such that the non-merger group produces two types of voiced lenis stops differing in the phonation of the following vowel. \n  \n(collaborative work with Julián Villegas and Mira Oh) \n  \n\n\n\nZoom meeting:\nhttps://hku.zoom.us/j/97258842055\n\n\nMeeting ID:\n972 5884 2055
