The study sought to isolate and identify patterns occurring in language interactions between mothers and their nonhandicapped and Down Syndrome children. Data were collected as part of a 3-year study of language interaction. Twenty nonhandicapped (NH) and 20 Down Syndrome (DS) children and their mothers were evaluated via a demographic inventory,…

Piaget's research on the processes and products of cognitive and representational development in early childhood is employed to outline the bases of early language development. The processes of assimilation and accommodation, leading to horizontal decalage; empirical and reflective abstraction, resulting in schemas and schemes; as well as…

Argues that knowing how infants process speech is a prerequisite to any definition of linguistic experience and therefore, the discrimination paradigm does not provide a test for the effect of experience on infants' speech discrimination. Outlines conditions to be met in order to conclude an effect of experience. (EKN)

Data on four infants between the ages of 12 and 20 months were collected to answer two questions about children's communication behavior. (1) Is there a correspondence between communicative intentions expressed in gestures and vocal utterances? If both spring from common organismic tendencies, it should be possible to discern an "indicating"…

This research project assessed: (1) the practicality of recording heart rate in 18-month-old infants as they watched events filmed on color, silent motion picture films; and (2) the validity and sensitivity of heart rate change as an index of differential attention arousal elicited by changes within and between complex visual events. The research…

Semantic-cognitive language sampling procedures to assess language development are used at the Kennedy Center Experimental School which serves handicapped children from 3 months to 6 years of age. A half hour of natural language is transcribed with a written description of the context. Fifty consecutive sentences or 100 utterances are selected and…

This study reports a replication of an earlier study by Kilbourne and Ginsberg (1980) which indicated the occurrence of a transition from predominantly coacting to predominantly alternating infant-mother vocalization patterns. In addition, the present study examined the modulating influences of nursing activity and mother's focus of attention upon…

Studied were some cognitive aspects of the language development of a 2-year-old Puerto Rican boy who had been on the U.S. mainland 1 month. A Neo-Piagetian approach (developed by K. Witz and J. Easley) was used to study: language behavior as being embedded in more complex, unified systems; productivity of different structures and language…

Video-analysis was used to investigate the transition from coacting to alternating patterns of infant-mother vocalizations in this longitudinal study of one infant. In addition to investigating the transition and its developmental implications, the relationship between the temporal patterning of kinesic and vocal behaviors was studied. The study…

This paper discusses the role of attention to uncertainty in mediating the transition from sensorimotor activity to language. It is proposed that language from the very beginning is used to resolve uncertainty by selectively marking points of change, deviation from the familiar or choice from among alternatives. Several research findings are…

A study examined the consistency of consonant use in the infant's transition period from babbling to early words. Phonetic data were collected from the speech of 10 infants aged 9 to 15 months. Analysis of consonant distribution patterns indicate striking segmental preferences in all 10 children, with some segments more prominent for the sample as…

A study of the babbling and phonological development of 54 infants used half-hour videotape recordings of the children at play in their own homes. The vocal output was phonetically transcribed twice for interrater agreement, and analyzed for the consonants used five times or more in the child's vocal repertoire. These consonants were considered to…

A mother's interactions with her young daughter were studied with special emphasis placed upon the frequencies of linguistically instructional input and the strategies employed to provide this information. The girl was between 18 and 28 months old and her mean length of utterance (MIU) was between 1.5 and 4.3 morphemes. Only maternal input was…

The influence of maternal language use patterns on the use patterns of the child was investigated in a black, low-income mother-child pair over a 20-month period, beginning at the child's 11th month of age. Video recordings were made of the pair's interaction in an unstructured playroom setting approximately every four weeks. Child multi-word…

In a comparison of the melodies in the speech of Mandarin Chinese and Caucasian American mothers, striking similarities were found: (1) in the overall distribution and average structure of melodic contours; (2) in close contextual links to given forms of intuitive parental care; and (3) in a tendency to neglect lexical tones in favor of pitch…
