要旨：Researchers have long been aware of ‘the invariance’ problem, where listeners and learners must determine underlying representations from variable surface forms. Some of this variation may be contextually induced, or may be a result of different speakers, different dialects or different speaking conditions. Much of this research has focussed on the level segments/phonemes. Much less is known about how similar types of variability are dealt with by children in the morphological domain. This talk will explore some of these challenges, reporting on recent findings exploring listeners and learners’ sensitivity to allomorphic variation and more. These results suggest that young learners are highly sensitive to all kinds of variation, rapidly constructing robust linguistics representations despite surface variation.

要旨：We have been carrying out a longitudinal project examining the cognitive development of infants (0 to 36 months old) who are at low-risk (LR) and high-risk (HR) for neurodevelopmental disorders such as the autistic spectrum disorder (ASD). One of the purposes of this study is to investigate early neurodevelopmental basis associated with social and language communication skills by employing functional near-infrared spectroscopy (fNIRS) and analyzing some behavioral measures. In this talk, I will report some current findings obtained so far from this project. I will particularly focus on various aspects of the mother-infant interaction and how they impact an infant’s language acquisition. In the first part of the talk, I will mainly discuss the behavioral results obtained from the still-face paradigm of 6-month-old infants and their mothers. We compared the results of covariance correlation analysis between or among social signals, including eye-contact, touch, vocalization, and contingency during still face paradigm and later language and social development. In principle, results were dissonant between LR and HR infants, and the contingent responsiveness of the mothers showed steady positive correlations with later language development (9-, 12-, 18-, and 24-month-olds) exclusively for the LR group. Furthermore, rhythmic touch (movement) and vocalization by the mother were powerful factors that had an impact on later language development, again only for the LR infants. The results of these infants’ brain responses and network while listening to the speech of the mother and a stranger were also analyzed. Consistent with the behavioral results, hemodynamic brain activity and connectivity in response to maternal speech were diverse between the LR and HR groups, while the LR group showed a very similar pattern to that of an LR neonate’s brain. I will also present two more fNIRS studies on the (1) hyperscanning of the mother-infant interaction of 3- and 4-month-olds (LR and HR) and (2) learning of non-adjacent dependency grammar in neonates and 6-month-olds (LR). These studies show neurodiversity and neural uniformity in relation to social and language functions.
