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…

This study assessed the relation between mother mental state language and child desire language and emotion understanding in 15--24-month-olds. At both times point, mothers described pictures to their infants and mother talk was coded for mental and nonmental state language. Children were administered 2 emotion understanding tasks and their mental…

Younger and older children were asked to label pictures of nonprototypic, container-like objects in an effort to test Nelson's theory regarding the primacy of the functional core in young children's meaning structures. Contrary to expectations, the older, intermediate age children were influenced more by functional context than were the younger,…

Evaluated an intervention designed to influence mothers' sensitive responsiveness toward their infant by presenting information about the newborn's competence to interact and promoting affectionate handling and interaction. Found that the enhancement group showed greater frequency of co-occurrences involving vocal exchanges, looking to the…

The concepts of front, back, and side may be easily understood in relation to an intrinsically fronted item, but with a nonfronted object they depend on situational or psychological cues. A study investigated a child's awareness of the front, back, and side of his own body and of fronted and nonfronted objects. Researchers hypothesized that a…

Normal and abnormal language development depends to a great degree on the nature of the infant-mother relationship. (Author)

Psychometric properties of the MacArthur Communicative Development Inventory (CDI) were examined. Findings suggested that the CDI reflects the progress of language development within the age range 10 to 27 months. Findings support caution in using results to identify individuals at risk for language deficits, to compare groups with different…

Fatherchild and motherchild engagements were examined longitudinally in relation to children's language and cognitive development at 24 and 36 months. The study involved a raciallyethnically diverse sample of low-income, resident fathers (and their partners) from the National Early Head Start evaluation study (n290). Fatherchild and motherchild…

The MacArthur-Bates Communicative Development Inventories (CDI; Dale, 1996; Fenson et al., 1994), parent reports about language skills, are being used increasingly in studies of theoretical and public health importance. This study (N=113) correlated scores on the CDI at ages 2 and 3 years with scores at age 3 years on tests of cognition and…

Examined the use by children of the Novel Name-Nameless Category principle, under the framework that lexical principles are acquired in a developmental sequence. Results indicated that the particular principle was not available at the start of lexical acquisition but that exhaustive categorization ability and a vocabulary spurt occur…

Presents evidence for four major design features of serial organization of speech arising from comparison of babbling and early speech with patterns in ten languages. Maintains that no explanation for the design features is available from Universal Grammar; except for intercyclical consonant repetition development, perceptual-motor learning seems…

Compared 100 three-year-olds with speech delay of unknown origin and 539 same-age peers with respect to 6 speech disorder variables; also examined abnormal hearing in a subset of 279 children. Found significant odds ratios only for low maternal education, male sex, and positive family history; a child with all 3 factors was 7.71 times as likely to…

Examined relationship between mother-child conversational interactions when children were 30, 36, and 42 months old and children's recall of these activities 1 day and 3 weeks later. Found that at all ages, features of activities jointly handled and jointly discussed were remembered better than features jointly handled but discussed by mother only…

Evaluates a comprehensive intervention program for deaf children under age three in Vancouver, British Columbia. Twelve subjects were compared with a matched sample of children undergoing less-systematic intervention. Results indicated more developmentally mature communication and higher quality interaction in families who had received…
