This paper provides the first evidence of maternal speech--motherese--in Wichi, an indigenous language with a complex morphology spoken in the Gran Chaco region of Argentina. The corpus consists of 22 hours of video recordings from the daily life of three children, starting from their one-morpheme utterance period (MLU = 1) to the onset of…

This study investigates 3- to 5-year-old children's sensitivity to lexical, intonational and gestural information in the comprehension of speaker uncertainty. Most previous studies on children's understanding of speaker certainty and uncertainty across languages have focused on the comprehension of lexical markers, and little is known about the…

Generative approaches to language have long recognized the natural link between theories of knowledge representation and theories of knowledge acquisition. The basic idea is that the knowledge representations provided by Universal Grammar enable children to acquire language as reliably as they do because these representations highlight the…

How do children develop the mapping between prosody and other levels of linguistic knowledge? This question has received considerable attention in child language research. In the present study two experiments were conducted to investigate four- to five-year-old Mandarin-speaking children's sensitivity to prosody in ambiguity resolution. Experiment…

With the ever increasing number of studies on formulaic language, we are beginning to learn more about the processing of formulaic language (e.g. Ellis et al. 2008; Siyanova et al. 2011), its use in speech (e.g. Aijmer 1996; Wood 2012) and writing (e.g. Hyland 2008a, 2008b) and its application in natural language processing (e.g. Tschichold 2000).…

Little research has been conducted on the development of suprasegmental characteristics of vocalizations in typically developing infants (TDI) and the role of audition in the development of these characteristics. The purpose of the present study was to examine the longitudinal development of fundamental frequency (F[subscript 0]) in eight TDI and…

This paper reviews Philip Lieberman's "Intonation, Perception, and Language," (Research Monograph No. 38) Cambridge, Massachusetts, M.I.T. Press, 1967. The review is also scheduled to appear in the "Journal of Linguistics." (JD)

Presents experimental evidence supporting the assertion that successive single-word utterances share certain suprasegmental characteristics with multiple-word utterances and that they are therefore not single words but the first manifestation of syntax in speech. (AM)

A case study of a 2-year-old progressing normally in speech development provides evidence of suprasegmental marking of the plural, thought to be adopted only in language-impaired children. Acoustic analyses of the durations and intensity of elicited words indicate that the child had adopted a suprasegmental strategy for marking the singular/plural…

This article reports on a study to determine the role of intonation in language acquisition. Related studies are mentioned. Research methods for the study are outlined and two case studies are reviewed. Conclusions show that adult-child interaction influences not only the child's use of intonation but also his acquisition of syntax. (Text is in…

A study investigated the order of acquisition of inflectional morphology in English within morphemes, focusing on late acquisition of one allomorph of the plural. It is proposed that late acquisition is rooted in the operation of the Obligatory Contour Principle (OCP), which states that at the melodic level, adjacent identical elements are…

Data on the acquisition of lexical tone were collected from 17 Mandarin-speaking children. Among other results, it was found that: (1) tone is acquired relatively quickly; (2) mastery of tones occurs well before mastery of segmentals; and (3) Mandarin high-level and falling tones are acquired before rising and dipping tones.

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,…

The syntax of adult expressive language is compared to that of child pre-language. This "syntactical regression" is considered part of the dynamic and evolutionary character of human language. (Text is in French.) (AM)

This paper is a report of two studies of the relationship between intonation and syntax. An analysis of intonation was used to decide whether the pivot-like two-morpheme constructions of a one- and one-half-year-old girl were single lexical items or two separate lexical items. Further, the intonation contours connected with her linguistically…
