In this longitudinal investigation of the emerging grammar of seven children, differences in linguistic acquisition were observed. Analyses revealed two distinct styles of syntactic acquisition that appeared to be sex- and speed-related with specific ties to particular utterance types and grammatical-relational specification.

This case study of two Latvian children attempts to show how the parental terms for"mummy" and "daddy" in Latvian are acquired, paying particular attention to the changing relationship between the input and output forms during the acquisition process. (Author/RM)

The phonotactic development of one child is traced from age 3;9 to 5;3. Data are presented in a table indicating both the child's phonological equivalent of adult consonant sequences and the range distinguished by the child at a given stage. (CHK)

The existence of a developmental sequence for the acquisition of specific complex syntactic structures in English was investigated through an analysis of eight studies of Danish subjects. The studies involved Danish speaking subjects acquiring English as a second language at ages 7-10, 13, and 18. The evidence from these studies demonstrate a…

A study of the utterances of young children, aged 7 to 22 months, is described. These utterances, varying in length from one to 17 syllables, contain only suprasegmental information because the verbal content was incomprehensible to hearers who were not acquainted with the child and the situation in which the utterances occured. In the corpus,…

This is a quarterly report of a project involving the analysis of the language of four Puerto Rican children living in the Boston area who are learning Spanish as a first language. The children, all male, ranged in age from 17 months to 37 months during the period of study. All had some contact with English. The data were transcriptions of…

THE AUTHOR FEELS THAT TO APPROACH CHILD LANGUAGE TRANSFORMATIONALLY IS TO USE A TECHNIQUE SUITED TO PROVIDING ADDITIONAL INSIGHT INTO A WELL-KNOWN LANGUAGE FOR TREATING AN UNKNOWN, OR AT BEST LITTLE KNOWN LANGUAGE. SHE MAKES THE FOLLOWING CRITICISMS OF TRANSFORMATIONAL ANALYSIS OF CHILD LANGUAGE--(1) NOTHING CAN BE DIRECTLY INFERRED WITH REGARD TO…

Four major areas of research into verbal development are discussed: (1) the relationships between behaviors hypothesized to be associated with one of the four major language skills, (2) the sequencing or ordering of behaviors within a skill, (3) the relationships between behaviors associated with different skills, and (4) the relationships between…

Sex differences in language development were studied. Protocols from 54 children, aged 2;0 to 4;2, were analyzed with Mean Length of Utterance (MLU) as the independent variable. When MLU's reached 3.75 to 4.0, differences began to favor girls. Results are discussed in terms of a social learning model and a cognitive model. (Author)

The 17-month (1967-1968) study summarized in this report concerned experimental analysis of the verbal behavior of disadvantaged preschool children (an interracial group of 28, ranging in age from 30 months to 42 months). Research was conducted in the verbal behavior laboratory at the University of Rochester and in a remodeled private home in a…

The nature of early games and how they might assist the infant in language acquisition were explored in a longitudinal study of two mother-infant dyads, using video-recordings of their free play. The analysis of appearance and disappearance games was particularly revealing. (EJS)

This paper represents a partial condensation of the results of a study covering 14 months in a Russian-speaking child's phonological development. Evidence supports a theory of phonological acquisition formulated by Olmsted (1971), and offers detailed information on the child's acquisition of specific phones. (CHK)

Describes a study to determine: (1) the relationship between age and mean length of utterance measured in morphemes (MLU) in a group of normally developing two- and three-year-old chidren; (2) the standard error of MLU; (3) the relationship between MLU and age; and, (4) the ability of MLU to predict children's grammatical development.
