Background: Behavioural and emotional problems occur at a high rate in children and adolescents with intellectual disability, often from a young age. Some studies have indicated that children and adolescents with autism present with even higher rates. Less is known about the presentation, development and family impact of these difficulties in…

Toddlers with slow expressive language development were compared on three global measures of phonological behavior to age-mates with normal speech development. The measures were the average level of complexity of syllable structures, the number of different consonant phonemes produced, and the percentage of consonants correctly produced in…

This study analyzes major federal programs designed to provide services to children, from birth through age 2, who have developmental delays or a high probability of developmental delays, and their families. Programs were selected based on their provision of education or health-related services to infants and toddlers with handicaps and their…

This study provides longitudinal observations of young children's behaviors while viewing television in their own homes, over a time when the children were actively involved in the process of language acquisition. A total of 16 children were observed for a period ranging from 6 to 8 months. At the beginning, their ages ranged from 6 and 1/2 to 29…

This longitudinal pilot study, which extends Veneziano's (1987) work on phonetically and semantically contingent maternal response types, compared, microanalytically and globally, maternal response types and mother-child dyadic interactions of normally developing and Down syndrome children. Participants were three normally developing infants, five…

Against the backdrop of evolving welfare policies in California following the approval of federal welfare reforms in 1996, the Growing Up in Poverty Project is examining how single mothers and their children fare as they move from cash aid to jobs, the types and quality of child care arrangements selected, and if mothers' access to child care…

Examines the spontaneous speech of Portuguese-speaking two-year olds in natural conversation with Portuguese-speaking adults. The children were separated into three groups based on Mean Length of Utterance in Words (MLUW). The children in the highest-MLUW group almost perfectly matched the adult speakers on every measure. (37 references)…

The Avon Longitudinal Study of Parents and Children (ALSPAC) provided descriptive data on the speech and language of 25-month-olds. Findings indicated great range in the stage of expressive language development achieved. Girls showed more advanced skills than boys. A clear pattern was identified in use of sound classes. Child verbal comprehension…

Investigates children's early lexical development in English and Korean and compares caregivers' linguistic input in the two languages. Results indicate that young Korean children use verbs productively with appropriate inflections and that, unlike in English, both verbs and nouns in Korean are dominant categories from the single-word stage. (39…

A cross-linguistic comparison of syntax acquisition patterns examined preferential subject omission in the naturally-occurring speech of three Japanese toddlers from the Tokyo area and compared the findings to data on English acquisition. Results indicate that acquisition patterns of Japanese do not mirror those of English with regard to this…

Research conducted in the United States and Canada on the effects of group care outside of family settings for 20 or more hours per week on a regular basis shows few differences between day care and home reared children on four major variables: attachment, social interactions, cognitive development, and physical health.

Observed home interaction between parents and 2- and 4-year-olds at Time 1 and 2 years later. Found that parent mental state talk to children varied by child's age, context of talk, and parent gender. Four-year-olds with older siblings produced and heard more cognitive talk and less desire talk than children without older siblings. Time 1 family…

Tested a proposed developmental pathway for toddlers' mastery of skills in generating non-ritualized forms of cooperative coordinated action with peers. Studied nonverbal imitative acts among U.S. toddlers and toddlers of the Seltaman people of Papua New Guinea. Found that ready imitation of one another emerged during the same developmental period…

Examined how child care experiences related to cognitive and language development from birth through age 3. Found that care quality was modestly related to cognitive and language outcomes, after adjusting for several factors. Cumulative experience in center-based care related to better outcomes than did experience in other care. Children in…
