Prosody plays a variety of roles in infants' communicative development, aiding in attention modulation, speech segmentation, and syntax acquisition. This study investigates the extent to which parents also spontaneously modulate prosodic aspects of infant directed speech in ways that distinguish semantic aspects of language. Fourteen mothers of…

The theory of syntactic bootstrapping proposes that children can use syntax to infer the meanings of words. This paper presents experimental evidence that children are also able to use word inflections to infer word reference. Twenty-four- and 30-month-olds were tested in a preferential looking experiment. Children were shown a pair of novel…

This paper focuses on how phrasal prosody and function words may interact during early language acquisition. Experimental results show that infants have access to intermediate prosodic phrases (phonological phrases) during the first year of life, and use these to constrain lexical segmentation. These same intermediate prosodic phrases are used by…

Discusses children's comprehension of complex sentences as measured by a picture selection test. Concludes that the interplay of both syntactic factors, such as active vs. passive, and nonsyntactic factors, such as expectation, must be considered in any characterization of children's sentence comprehension ability.

Proposes a model of syntax in which marked structures are conceived as the realization of modes of control that regulate the informational flow of the text at points of threatened discontinuity. Describes two of these modes, found in children's writing, which are concerned with relations of logic and focus. (Author/SED)

A comprehension task employing English animate third person pronouns was run on 100 children from three to seven years of age. Results show that comphrehension of forms beyond chance level first appears at age five, with continuing improvement through ages six and seven. Mastery of gender distinction preceded number and case. (Author/PJM)

This study looks at the syllable onset interval (SOI) patterning in Taiwan Mandarin spontaneous speech and its relationship to discourse and syntactic units. Monologs were elicited by asking readers to tell stories depicted in comic strips and were transcribed and segmented into Discourse Segment Units (Grosz & Sidner, 1986), clauses, and…
