This study was designed to provide a general picture of infant vocal-motor coordination and test predictions generated by Iverson and Thelen's (1999) model of the development of the gesture-speech system. Forty-seven 6- to 9-month-old infants were videotaped with a primary caregiver during rattle and toy play. Results indicated an age-related…

The purpose of study was to investigate the impact of pre-surgical Infant Orthopaedics (IO) on consonant production at 18 months of age in children with Unilateral Cleft Lip and Palate (UCLP) and to compare the consonant production to that of age-matched children without clefts. The first ten children in a consecutive series of 20 with UCLP…

The poverty of stimulus argument is one of the most controversial arguments in the study of language acquisition. Here we follow previous approaches challenging the assumption of impoverished primary linguistic data, focusing on the specific problem of auxiliary (AUX) fronting in complex polar interrogatives. We develop a series of corpus analyses…

Few models appropriately or adequately describe the literacy development experiences of children with atypical communication development, such as those with language impairment or severe disabilities. In this paper, the Interactive-to-Independent Model of literacy development is presented, influenced primarily by Vygotsky's seminal theories of…

The interaction between prosodic and segmental aspects of infant representations for speech was explored using the head-turn paradigm, with untrained everyday familiar words and phrases as stimuli. At 11 months English-learning infants, like French infants (Halle & Boysson-Bardies, 1994), attended significantly longer to a list of familiar lexical…

Because of its potential importance for word learning, children's judgment of whether they know names for objects was investigated. In Study 1, judgment accuracy was at or near ceiling in about two-thirds of 4-year-olds, and covaried with judgment of word familiarity and with justifying novel name mapping in terms of avoidance of name overlap. The…

This study investigated the relationship between discourse deficits to a broader range of other symptoms in 57 children with autism. We hypothesized that autism symptomatology, as measured by the Autism Diagnostic Observation Schedule (ADOS), would be related to the children?s difficulty in maintaining an ongoing topic of discourse. Children…

This study assesses children's understanding of the Italian modal verbs "dovere" (must) and "potere" (may) in their dual function of qualification of the speaker's beliefs (epistemic modality) and behaviour regulation (deontic modality). 192 children and 60 adults participated in the experiment. Children aged 3;0 to 9;2 were presented with two…

This research investigates language-general and language-specific properties of the acquisition of argument structure. Ten French preschoolers enacted forty sentences containing motion verbs; sixteen sentences were ungrammatical in that the syntactic frame was incompatible with the standard argument structure for the verb (e.g. *"Le tigre va le…

Thirty-six three- to four-year-old children were tested to assess whether hearing a word-referent link from an ignorant speaker affected children's abilities to subsequently link the same word with an alternative referent offered by another speaker. In the principal experimental conditions, children first heard either an ignorant or a…

This paper examines the nature of finite and nonfinite main declarative sentences produced by L2 child learners. It claims that two of the main proposals on the root infinitive (RI) phenomenon, the Truncation Hypothesis (TH) and the Missing Surface Inflection Hypothesis (MSIH), are not mutually exclusive in child SLA because they are hypotheses on…

In a study of adults' attitudes toward children with limited linguistic competence, four groups of judges listened to audiotaped samples of preschool children's speech and responded to questionnaire items addressing child attributes (e.g., intelligence, social maturity). Systemic biases were revealed toward children with limited communication…

The author discusses the benefits of applying cognitive linguistics, L1 acquisition, and neo-Vygotskian (Vygotsky) approaches to the teaching of a second language to young learners, using the example of teaching the preposition "on." The author briefly reviews how prepositions are taught to adult learners and the challenges of teaching…

There has been little research comparing the nature and contributions of language input of mothers and fathers to their young children. This study examined differences in mother and father talk to their 24 month-old children. This study also considered contributions of parent education, child care quality and mother and father language (output,…

Participants in this study were 66 British toddlers who were observed at home with familiar peers on two occasions, six months apart. The majority of toddlers spoke to their peers, with short sequences of conversation emerging after the age of 24 months. The use of possessive pronouns emerged between 18 and 24 months of age and consolidated over…
