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)

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.

A study was undertaken to determine whether children in early periods of language development use stress with any regular patterns, and if so, on what the patterns are based. The subjects were five children aged 21-29 months, MLU between 1.3 and 2.4. Tape recordings were made during play sessions with each child. Two-word utterances that could be…

This document is Part II of a two-part project whose object was to identify children's sequential development from birth through age seven and to identify the materials which would be used to strengthen or initiate a behavioral facet. The materials surveyed for potential use with preschool children are described as ranging from standard toys…

THIS PAPER IS A STUDY OF A CHILD'S EARLIEST PRETRANSFORMATIONAL LANGUAGE ACQUISITION PROCESSES. A MODEL IS CONSTRUCTED BASED ON THE ASSUMPTIONS (1) THAT SYNTACTIC ACQUISITION OCCURS THROUGH THE TESTING OF HYPOTHESES REFLECTING THE INITIAL STRUCTURE OF THE ACQUISITION MECHANISM AND THE LANGUAGE DATA TO WHICH THE CHILD IS EXPOSED, AND (2) THAT…

A comprehensive bibliography on linguistic input in the home, clinic, and/or classroom is presented. Three general categories of materials are included: language spoken to normal children, cross-cultural studies, and language spoken to special populations. Linguistic input is a term that refers to the special language register that parents use to…

This document is Part I of a two-part project whose goal was to identify the sequential development of child behavior from birth through age seven and to identify the materials which could be used to strengthen or initiate a behavioral facet. Research on child development was collected, organized, and analyzed for correlative events pertinent to…
