This study explores the developmental change of mother-child interactions in order to investigate which aspects of maternal behavior affect children's speech production. To this end, the interactions between 79 German-speaking mothers and their two- or five-year-old children were observed at two time points (12 months apart) and in two interactive…

A group of preschool-aged children with specific language impairment (SLI), a group of typically developing children matched for age (TD-A), and a group of younger typically developing children matched for mean length of utterance (TD-MLU) were presented with novel verbs in contexts that required them to inflect with past tense "-ed."…

A cross-sectional research study and a longitudinal research study failed to replicate previous research findings that indicated a linear relationship between age and mean length of utterance during the preschool years. Instead, a deceleration in age curves, particularly beyond about 36 months, was observed in each sample. (Author/CB)

To test D. Stampe's hypothesis about the development of phonological processes, 60 children (21 to 48 months old) were placed into groups based on mean length of utterance (MLU) and chronological age. MLU was found to be the best classification for describing the phonological processes. (Author/SEW)

The variation of mean length of utterance, a linguistic measure, is explored among 50 normally developing three-, four-, and five-year-olds. It is suggested that mean length of utterance, as a measure of language status, is limited in differentiating language-impaired from normally developing children. (Author/SJL)

Analyzed videotapes of 3- to 7-year-old Singaporean children to document play and language level. Data analysis revealed a developmental trend in play and language scores, several significant gender differences in Smilansky's and Parten/Piaget play categories but no significant gender differences in language scores. Socioeconomic status…
