Ambridge's proposal cannot account for the most basic observations about phonological patterns in human languages. Outside of the earliest stages of phonological production by toddlers, the phonological systems of speakers/learners exhibit internal behaviours that point to the representation and processing of inter-related units ranging in size…

The conversational timing patterns of three year old children who were at a high familial risk for dyslexia were examined in the course of their interaction with adults. Findings indicated that previously documented differences in speech timing surface as subtle differences in spontaneous child-adult conversation as early as three years of age.

Adult "redoing" sequences (expansions and repeats) in conversations between adult and child (age 1;6) are analyzed with a conversational analytic approach, and two ways in which redoing sequences are involved in the initiation of repair are explored. It is proposed that a redoing sequence picks up a child's utterance and displays it for some kind…

A comparison is presented of a mother's language to her Down Syndrome two-year-old and his normally developing twin. When interacting with the Down Syndrome twin, the mother used shorter mean length of utterance, greater type-token ratio, more confirmations, more verbal directives, fewer yes-no and true questions, and more directive questions.…

This study investigated the earliest manifestations of verb tense and agreement in English-speaking children, using longitudinal data on the language of four children aged 1:6 to 3:5 years, drawn from a child-language database. Analysis focused on one aspect of inflectional phrase (IP), the children's use of the verbs "be" and "do" forms to mark…
