Investigation of the acquisition of Tamil verb inflections in three two-year-old children revealed a high percentage of usage of verb inflections indicating tense, aspect, modality, person, number, and gender. Explanations for this early, almost error-free language acquisition are explored in terms of the facilitating properties of agglutinating…

Infants' habituation and mothers' encouragement of attention were assessed at 5 months. Toddlers' language comprehension, language production, and pretense play, and mothers' encouragement of attention, were assessed at 13 months. Examined the contributions of infant habituation and maternal stimulation to toddlers' cognitive abilities. (PCB)

Investigates conversational characteristics (discourse features, illocutionary force and style parameters) of mothers of two-year-old twins and mothers of two-year-old singletons with older siblings. Finds significant differences in conversational characteristics, and between twins' and singletons' language scores on measures of language…

Patterns of growth in one language in relation to growth in the other and also with respect to growth in both languages were studied in a group of 20 bilingual (English/Spanish) infants ages 10 to 30 months. The rate and pace of development were similar in both groups; differences among the bilinguals included their use of "referential"…

This study examined whether toddlers build a repertoire of words as integral sequences of gestures and then differentiate these sequences into their gestural and segmental components. Results demonstrate clear differences in duration and coordination of gestures between children and adults and a shift toward the patterns of adult speakers during…

Data from a transcript database of 12 children collected in 1-hour samples every month from 1;0 to 3;0 support the hypothesis that there should be strong differences in the frequency and types of errors between pronouns with suppletive nominatives and those without. The suppletive nominative forms "I" and "she" are blocked from overextension in a…

Working class and upper-middle class mothers were videotaped interacting with their toddlers in four settings. Samples of the mothers' adult-directed speech were also collected. Observed were social class differences in the mothers' child-directed speech and some parallel differences in the mothers' adult-directed speech. This may reflect more…

Administered the MacArthur Communicative Development Inventory to 25 bilingual (English/Spanish) and 35 monolingual children who were furnishing data for longitudinal study. Assessment of the degree of overlap between bilingual children's lexical development in their two languages showed that they developed early vocabulary at the same rate as…

A portrait is presented of the toddler with slow expressive language development (SELD), based on research examining the health history; cognitive, communicative, and adaptive skills; behavior; and phonology of 30 toddlers with SELD and 30 nondisabled toddlers. The paper offers a review of research on the outcomes of SELD, and explores…

This paper analyzes Piagetian theory on the relative development of cognition and language, the local homology model which claims there are specific language-cognition relationships at specific points in time, normal development and local homology, and development in language-impaired children. Implications for clinical decision making are…

Tested a normally developing child several times between 16 and 27 months of age for his ability to derive the relations between stimuli. Found that the child derived "mutual entailment" relations and showed "nonverbal exclusion" as early as 17 months. "Combinatorial entailment" relations and "verbal…

While children aged 1;10 and 2;1 show only a modest rate of mapping novel nouns onto unfamiliar rather than familiar objects, children aged 1;4 and 1;8 show a high rate. Two studies with young 2-year olds found the noun-mapping preference prevalent, but unless initial choices are strongly reinforced, increase in salience of familiar kinds lures…

A study involving 58 children (17 to 36 months) with developmental disabilities in the prelinguistic period of development and their mothers found that the relationship between intentional communication and later language was, in part, due to covarying relationships with maternal responsivity. (Author/CR)

Examines three alternatives to the classical framework of early cognitive development: modularity-nativism, connectionism, and theory-theory. Arguments are marshaled to support the "theory-theory" view, which emphasizes a combination of innate structure and qualitative reorganization in children's thought based on input from the people and things…

Data are presented from two studies that investigated short- and long-term outcomes of early identification and intervention for young children from birth to age 3. Results from the studies support the immediate and longer-term benefits of early entry into intervention for language, academic, and social-emotional development. (Contains extensive…
