Speech disorder in preschool children exposed to Cantonese and English

Speech disorder in monolingual Cantonese- or English-speaking children has been well described in the literature. There appear to be no reports, however, that describe speech-disordered children who have been exposed to both languages. Here we report on the error patterns of two preschool speech-disordered children who were learning two languages. Both children's first language was Cantonese, but they were also exposed to English through the media and child care. Their disorders were of unknown aetiology. The following questions were asked of the data: (a) Do bilingual children, suspected of having speech problems, make errors in Cantonese and English that reflect delay or disorder when compared with normative data on monolingual speech development in each language? (b) How does the children's speech differ from other bilingual children from the same language learning background? (c) Are the children's speech difficulties apparent in both languages? (d) Is the pattern of errors the same in both languages or do language-specific processes operate? The results bear on theories of acquisition, disorder and bilingualism; they also have clinical implications for speech-language pathologists whose caseloads include bilingual preschool children.

Introduction: Casting new light on old stones

The purpose of this monograph is to take a new look at various aspects of stone artefact analysis that reveal important and exciting new information about the past. This invovles reorienting our methodological approach to stone artefacts as well as the questions asked of them. The papers making up this volume tackle a number of issues that have long been at the heart of archaeology’s problematic relationship with stone artefacts, including our understanding of the dynamic nature of past stoneworking practices, the utility of traditional classificatory schemes, and ways to unlock the vast amount of information about the strategic role of lithic technology that resides in stone artefact assemblages.
