A common assumption underlying cross-linquistic studies in child language is that the comparison of any feature in unrelated languages may simplify semantic-grammatical complexities in a way that studies on a single language cannot. This paper begins by discussing the order of acquisition of grammatical morphemes in Spanish by four…

Since speech pathologists are interested in the role nonfluent behavior may play in the onset or development of stuttering, this study compared the linguistic behavior of 17 fluent four-year-old children to that of 17 nonfluent children similar in age, intelligence, sex, sibling status, race, socioeconomic status, and education. The aspects of…

Every speech community has a baby talk register (BT) of phonological, grammatical, and lexical features regarded as primarily appropriate for addressing young children and also for other displaced or extended uses. Much BT is analyzable as derived from normal adult speech (AS) by such simplifying processes as reduction, substitution, assimilation,…

This paper proposes a broad outline of a variable model of language development and explores several particulars of such a model in the language behavior of four two-year-old children. The process by which information about language is progressively transformed and integrated rather than merely being added together can be seen in the shifting…

This analysis of Brazilian baby talk (BT) includes data from two sources: elicitations of the use of BT from three mothers, all of whom have university degrees, and observations of adult-child interactions in the home. The data shows Ferguson's modified list of thirty lexical items that frequently have BT forms in various languages and the…
