The effects of intonation morphemes on the processing of simple reversible sentences containing a dislocated element were studied using synthetic speech stimuli. Both child and adult subjects processed the sentences better when they retained standard subject-verb-object order, suggesting that the morphemes serve as processing instructions.…

Examines, through a longitudinal study, the temporal correspondences of 4 Japanese children, aged 7 to 11, in the attainment of specific milestones in play and language. All children proceeded through the same sequence of stages, but the rate of development was different depending on their environment. (34 references) (GLR)

Twenty-eight toddlers with slow expressive language development were compared to normally speaking age-mates and found to show delayed rather than deviant development in the average level of complexity of their syllable structures, the number of different consonant phonemes produced, and the percentage of consonants correctly produced in…

This paper investigates the development of interactive communication skills in 170 children aged 7 to 13. Results indicate that the development of interactive communication skills is rather different from the process of language acquisition both in the extended timescale involved and in the considerable variability exhibited by speakers of…

Examines the role of grammatical prerequisites in code switching in young bilingual children. Grammatical constraints are not violated in the earliest uses of mixing. Code switching occurs early in life within these constraints when a certain kind of grammatical knowledge is accessible and functional categories are implemented in the child's…

Addresses recent advances in research and theory that relate to language shift in early childhood, cognitive, and academic consequences of bilingualism and second-language learning, and theoretical models for conceptualizing the development of bilingualism and second-language learning. Contains annotated bibliography. (47 references) (LET)

Results of a longitudinal case study of a monolingual Sesotho-speaking boy show that rule-assigned tone on subject markers is marked appropriately by age two. Underlying tonal representations on verb roots are learned gradually over time, showing an early Default High tone pattern. (Contains 51 references.) (Author)

Reprints a talk presented to teacher trainers in 1990 that surveys thinking on language acquisition, specifically on the transition from orality to literacy, focusing on Montessori connections and applications. (HTH)

A study of subject-verb agreement in 3-year-old speakers of Brazilian Portuguese found an overall low error rate, but with important contrasts in both frequency of production of different verb inflections and rate of agreement errors associated with them, suggesting subject-verb agreement is acquired piecemeal and the learning of particular verb…

A study investigated the extent to which the nature of verb input accounts for the order in which children acquire verbs. Subjects were 57 mothers and their Stage I children. Results suggest that the effect of syntactic diversity in input supports the "syntactic bootstrapping" account of how children use structural information to learn new verbs'…

A study of 71 mothers interacting with their 2- to 5-year-old children analyzed structural organization and communicative function of their speech and identified three maternal communicative styles: non-intervening; explaining; and directing. Internal consistency of the three styles appeared to be both satisfactory and related to relevant child…

Examined mothers' and preschoolers' emotion talk for age- and gender-related patterns in use of labels and explanations. Found that children used emotion words mainly in labels. Boys' emotion talk increased with age. The youngest girls had more emotion talk than same-age boys. Mothers used more explanations than labels with boys but similar…

Investigates how early a developing bilingual who is exposed simultaneously to English and Spanish can make appropriate language choices. Kept detailed records of the child's cumulative vocabulary from the first word at 10 months and on weekly audiovideo recording in both Spanish and English contexts from age 1-3. (Author/VWL)

Two experiments suggest that adults and even preschoolers possess interpretive structures--particularly object structure--that are nonclassical in the sense that they can be used to resolve an apparent contradiction. Results further suggest that certain interpretive structures present themselves in reasoning about particular predicate-object…

Basque auxiliary verbs encode tense, agreement relations with ergative, absolutive, and dative arguments, which constitute an inflectional verbal amalgam whose acquisition is not problematic for Spanish-speaking children but is for Spanish-speaking adults. This asymmetry is due to different processes by which the inflectional amalgam is acquired.…
