Amount of Input Overall amount of parent speech accounts for a substantial amount of variation in vocabulary growth. The relative frequency of exposure to specific words is related to the order of acquisition of those words. Huttenlocher et al (1991) 48 M words 28 M words 12 M words

Réseau canadien de recherche sur le langage et l’alphabétisation CANADIAN LANGUAGE & LITERACY RESEARCH NETWORK Partager la science. Éveiller les esprits. ● sharing the science. opening minds. Cognitive Learning Mechanisms: Categorization Skills In the first year of life, infants acquire language-specific speech perception skills. Visual categorization skills are associated with the acquisition of language specific knowledge of the maternal speech sound system. Speech perception and visual categorization both involve statistical learning.

Réseau canadien de recherche sur le langage et l’alphabétisation CANADIAN LANGUAGE & LITERACY RESEARCH NETWORK Partager la science. Éveiller les esprits. ● sharing the science. opening minds. Social Learning Mechanisms Typically, infants prefer speech to any other type of auditory input Infants especially like their mother’s speech, produced in an infant directed register. Some infants appear to be born without this preference for speech input. Hearing impairment interferes with attention to speech.
