Communication skills change with age as a result of sensory deficits, memory loss, and increasing word finding difficulties The Keep on Talking program (L. Hickson, H. Barnett, L. Worrall, & E. Yiu, 1994) was developed to assist older people to develop their own strategies for maintaining communication skills into old age. Two hundred and fifty-two...

The Western Aphasia Battery (WAB) is a standardized aphasia test which classifies aphasias into eight syndromes based on the Wernicke-Lichtheim model, commonly known as the Bostonian model. Although the syndrome approach has its limitations it is a widely used procedure in clinical aphasiology as it allows users to classify patients into discrete s...

Speech therapy services in Hong Kong have changed dramatically in the past two decades. Further development is urgently required in three main areas; norms of speech and language development in Cantonese, descriptions of disordered communication in adults and children, and the development of screening and diagnostic speech and language instruments....

The use of volunteers in aphasia therapy has always been controversial. Studies examining the efficacy of therapeutic programmes provided by speech pathologists and volunteers have not always identified differences between the two groups of therapy provider. This paper examines previous efficacy papers from a methodological perspective and discusse...

Chinese is a language with little inflectional morphology. It is also characterized by the frequent use of elliptical sentences because of its usual omission of topic and grammatical subjects in sentences. It has been suggested that these characteristics may obscure the distinction between normal and agrammatic speech. Nevertheless, the findings fr...

The majority of studies on grammatical disruption in aphasia have focused on European languages. Theories developed from the observations made with these monolingual studies are often limited by the specific characteristic of the language under investigation. Therefore, recent aphasiology research has attempted to look at cross-language comparisons...

Nominal group technique (Delbecq, Van de Ven, & Gustafson, 1975) was used with seven groups of elderly people and two groups of professionals who work with the aged to determine the communication difficulties that community‐based older people experience and to determine appropriate content for a proposed education program. The older people perceive...

Studies of agrammatism usually rely on selecting ‘agrammatic’ speakers by using a pre-determined definition. The grammatical disruptions demonstrated by these selected subjects are then examined and accepted as the basis for identifying further agrammatic subjects. Such an approach is not only tautologous but also entails a certain degree of subjec...

The Boston Naming Test (BNT) is frequently used to assess for word-retrieval difficulties, but its use outside North America is restricted by items such as ‘beaver’ and ‘pretzel’. A total of 136 older Australians were tested on the BNT. Those items which frequently produced naming errors were identified and alternative items trialled. Age, years of...

ABSTRACTS Tone language speakers use lexical tone or fundamental frequency to signal meaning. Therefore, native tone language alaryngeal speakers encountering difficulty imparting lexical tone variation would suffer loss of speech intelligibility. This study examines the intelligibility of lexical tone produced by four different alaryngeal speech m...

The characteristics of Chinese being a logographic and tonal language has often made it attractive for research. In particular, the right hemisphere has been postulated to be more important in Chinese because of its superiority in prosody and visuo-spatial processing. Literature on Chinese-speaking aphasia is usually single case studies and without...

ABSTRACTS The incidence of language delay in Chinese preschool children was studied by a stratified proportional sampling of all 3 year olds in Hong Kong. The Developmental Language Screening Scale (DLSS) devised for use with Cantonese speaking children was used to identify children with language delay. Of 855 children sampled in the stage I screen...

This study provided a preliminary investigation of the occurrence and distribution of voice problems of residents of Hong Kong. The subjects were sampled from patients receiving voice therapy. Background data such as laryngeal pathologies, age, sex, occupations and other “at-risk” factors are presented. Vocal abuse appears to be the primary underly...
