| Research Abstract |
The aim of this research was to clarify the mechanism of children’s language development promoted by various cues in caregiver’s speech. The focus was on word learning strategy from infants’ perception and cognition of speech sounds to children’s processing of lexical meaning. Two points were studied: (1)the relation between speech sound perception and lexical acquisition, and (2)the influence of social interaction on speech sound perception and lexical acquisition. The results showed the features of particles and onomatopoeia in speech perception and cognition by infants and the influence of non-linguistic sounds to infants’ development. The research also clarified the process that mothers change their speech according to the developmental stage of their children and how maternal speech promotes children’s inference of lexical meaning.
