This volume brings together a collection of empirical studies on phonological acquisition and disorder of monolingual children speaking different languages (English, German, Putonghua, Cantonese, Maltese, Telugu, Colloquial Egyptian Arabic and Turkish) and bilingual children speaking different language pairs (Spanish-English, Cantonese-English, Mirpuri/Punjabi/Urdu-English, Welsch-English, Arabic-English and Putonghua-Cantonese). The research findings provide much-needed baseline information for clinical assessment and diagnosis as well as valuable evidence concerning theories of language acquisition and the role of the ambient language.

Developmental Phonological Disorders: Foundations of Clinical Practice, Second Edition is the only graduate-level textbook designed for a competency-based approach to teaching, learning, and assessment. The book provides a deep review of the knowledge base necessary for the competent assessment, diagnosis, and treatment of developmental phonological disorders. Thoroughly revised and updated, the textbook contains learning objectives in each chapter to further support understanding of concepts and carefully designed case studies and demonstrations to promote application to clinical problem solving. Key Features: Learning objectives for each chapter subsectionIncludes the "how, why, and when" to apply each assessment and treatment procedure in clinical practice62 tables containing clinically relevant information such as normative data to interpret phonological assessment results99 figures to support clinical decision making such as recommending a treatment delivery model, selecting treatment targets, or choosing evidence-based interventions35 case studies to support a competency-based approach to teaching and assessment35 demonstrations that show how to implement assessment and treatment procedures The second edition provides a comprehensive overview of seminal studies and leading-edge research on both phonological development and phonological disorders, including motor speech disorders and emergent literacy. This wealth of theoretical background is integrated with detailed descriptions and demonstrations of clinical practice, allowing the speech-language pathologist to design interventions that are adapted to the unique needs of each child while being consistent with the best research evidence.

Paediatric speech and language therapists are challenged by diminished resources and increasingly complex caseloads. The new edition addresses their concerns. Norms for speech development are given, differentiating between the emergence of the ability to produce speech sounds (articulation) and typical developmental error patterns (phonology). The incidence of speech disorders is described for one UK service providing crucial information for service management. The efficacy of service provision is evaluated to show that differential diagnosis and treatment is effective for children with disordered speech. Exploration of that data provides implications for prioritising case loads. The relationship between speech and language disorders is examined in the context of clinical decisions about what to target in therapy. New chapters provide detailed intervention programmes for subgroups of speech disorder: delayed development, use of atypical error patterns, inconsistent errors and development verbal dyspraxia. The final section of the book deals with special populations: children with cognitive impairment, hearing and auditory processing difficulties. The needs of clinicians working with bilingual populations are discussed and ways of intervention described. The final chapter examines the relationship between spoken and written disorders of phonology.

Originally published in 1991, the recent developments in the study of phonological disorders in children had led to a fruitful interaction between speech pathology and phonology. It is one aspect of the application of linguistic theory to the study of speech and language disorders which had opened up a new field, clinical linguistics. This book brings together the concerns of the linguist and the speech pathologist; the essays chosen share the quality of not discussing theory or therapy without addressing the implications one has for the other. By concentrating on recent work the editor hoped to stimulate further discussion in this important and fast growing area of research.

Calling this a major contribution to the field of psycholinguistics, Professor Dennis Mol­fese notes that it "stands out as perhaps the major work in the area of phonological de­velopment in the last decade. It should be­come a major reference work and the proce­dures employed (both for data collection and, perhaps, more so for data analysis) could well set the tenor for the next decade." The eight essays by various contributors in this book review the literature on phonological development, emphasizing prob­lems relating to age, phonemes, and distinc­tive features. The methodology of data collection, storage, retrieval, presentation, and analysis is described. Data are presented descriptively by individual chapters for each of five age groups: 18, 24, 36, 48, and 72 months. Summary data are presented, using both descriptive and inferential statistics across the entire sample. One hundred children, 20 at each age group, served as subjects. All language sam­ples were collected in spontaneous situa­tions. A total of 86,661 phonemes was en­tered for analysis. Two distinctive feature systems--the Irwin-Wong and the Chom­sky-Halle--were employed in all analyses. Data for both phonemes and distinctive fea­tures were presented in terms of distri­bution, acceptability of production, and na­ture of any replacement.

This is the first book-length study of phonological development and impairment of Chinese-speaking children. It provides the first normative data on this population, which will be of value to speech and language therapists and other professionals. It also advances the notion of 'phonological saliency' which explains the cross-linguistic similarities and differences in children's phonological development.
