A set of tri-zygotic quadruplets, three girls and one boy, participated in weekly observations from 1;2 to 1;10 (years;months), a period of transition from prelinguistic gesture to 50 words. In the study, one girl served as a genetic mate to her identical twin and a biological risk mate to her fraternal sister. The biological risk mates achieved…

The purpose of this paper is to demonstrate that children's use of Japanese case particles obeys the grammatical principles introduced at the earlier stage of language development. In previous studies concerning the acquisition of Japanese case examined through the experimental method, it has been suggested that children acquire the functional use…

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 investigated variables that might be associated with outcome differences in language development of 10 children (ages 10-20 months) with blindness or severe visual impairments, attending a developmental vision clinic in southern England. Subjects' early patterns of expressive language development were examined and related to observed…

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 manual designed for caregivers describes the practices and activity plans of the infant-toddler group at the University of Iowa Early Childhood Education Center. Emphasis is placed on working with children between 12 and 36 months of age. The manual is divided into five main sections. Section 1 explains the composition of the infant-toddler…

Considers issues that challenge parents and professionals faced with the need for infant group care: nurturing in the infant caregiver, staff stability, economics of staff/infant ratios, the role of language in caregiving, altruism in babies, group versus individual time, control and power issues, caregiver training, and "people…

Provides longitudinal observations of young children's behaviors while viewing television in their own homes when the children were actively involved in the process of language acquisition. The observations show an overwhelming and consistent occurrence of language-related behaviors among children and parents in the viewing situation. (Author/SED)

A study involving 356 twin pairs with early language delay found environmental influences shared by both twins were more substantial than genetic factors. Heritability was significantly higher in those with persisting difficulties but only when assessed in terms of parental concern at 3 years or professional involvement at 4 years. (Contains…

Notes the importance of positive human interactions and experiences on child development, and describes seven developmental areas crucial to early brain development. Suggests ways to enhance young children's development of emotional intelligence, social skills, motor skills, vision, language acquisition, vocabulary, and thinking skills. (TJQ)

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…

Analysis of negative utterances from English-, French-, and Korean-speaking one- through three-year-olds identified nine distinct semantic/pragmatic categories with a similar developmental order in all three languages. Different patterns were found in the form-function relationship for the different categories. (Author/CB)

This case study describes an intervention program with a 20-month-old hearing child with deaf parents. The child was diagnosed as having a significant delay in both spoken and sign language. A home-based intervention program resulted in the child's increased use of sign and spoken vocabulary and the mother's improved interaction style. (Author/DB)

Describes the phoneme repertoires and phonological error patterns used by Cantonese-speaking children, as well as a longitudinal study of tone acquisition by four children. The developmental error patterns used by more than 10% of children are reported as common in other languages. Specific rules associated with Cantonese phonology are identified.…

Examined language differentiation in bilingual toddlers prior to the emergence of functional categories. The children were observed with each parent separately and both together. Results indicate that while these children did code mix, they were able to differentiate between their two languages. There was some evidence that language dominance…
