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"…

Piaget has suggested that a child's language reflects the degree to which he is able to take into account the point of view of his listener. His inability to do so results in what Piaget calls egocentric speech whereas what Piaget calls socialized speech indicates that the child actually adopts his listener's viewpoint and engages in an exchange…

Tests the hypothesis that the extent to which the durations of pauses (silences within the utterances of a single speaker) and switching pauses (silences between the utterances of 2 speakers) in the speech of children in conversation become similar (i.e., exhibit conversational congruence) is positively related to age. (BRT)

Describes adjustments in speech patterns made by two- and three-year-olds when talking to their 14-month-old siblings and compares these changes with those made by mothers addressing their babies. Individual differences between the children indicate two types of influence on the adjustments made--pragmatic and emotional. (EKN)

A study was conducted to determine the relationship between maternal input to early language learners and language acquisition and to answer the following questions: (1) Does nursery language used with the child change after he begins to talk? (2) Is there reason to believe that the child's speech is influenced by or influences the mother's…

Vowel production of a 14-month-old girl was studied over a 6-month period. Sixty percent of the vowels were produced correctly. A complex pattern of vowel preferences and errors was partially related to prespeech babbling preferences and strongly related to word structure variables (monosyllabic versus disyllabic). (Author/JDD)

Data are presented to show that reinforcement and exact repetition of adult speech are beneficial but not necessary components of a modeling procedure which results in production of novel linguistic forms by children. Laboratory studies suggest the need for a re-evaluation of current hypotheses about the limited role of imitation in language…

Any theory of language acquisition must take into account the actual speech heard by children during the acquisition period. When 8 well-educated mothers were tape-recorded talking to their daughters, ages 16 to 30 months, it was found that their speech differed significantly from that spoken to another adult. The mothers used a more restricted…

The system of deriving baby speech from adult speech is discussed. The theory is based on the system of consonantal replacements. (NCR)

The study evaluated the effects of an auditory monitoring and feedback approach on an adolescent boy's schizophrenic language patterns. The approach attempted to increase the subject's auditory awareness and to train him to identify and correct the linguistic errors of others and, eventually, of himself. Language samples were analyzed at baseline…

The intent of this study was to examine the development of three aspects of preschoolers' private speech: coefficients of egocentricism, the extent to which speech regulates actions, and the syntactic and semantic structures of individual utterances. Forty-one randomly chosen preschoolers (26 females, 15 males) were placed in three age groups (3,…
