Hearing Science and Hearing Disorders focuses on the nature of the processes in the inner ear and the nervous system that mediate hearing. Organized into eight chapters, this book first discusses the nature of speech communication, the extent of hearing problems, and the pathophysiology of hearing. Four core chapters follow, in which four areas of central importance to understanding hearing disorders and their effects are covered. These areas are assessment of auditory function, the scope for technological solutions, the nature of audio-visual speech perception, and the effects of deafness upon speech production. This book will be valuable to students; to academic and professional workers concerned with hearing, speech, and their disorders; and to scientifically or medically literate people in general.
Speech and Language: Volume 5, Advances in Basic Research and Practice is a collection of papers dealing with clinical issues, theories, and pathology of language and speech. Several papers discuss developmental apraxia of speech, relapse of stuttering therapy, the single subject research design, and the implications of the physiologic, acoustic, and perceptual aspects of coarticulation. Other papers analyze language development, language training, the three aspects of voice quality element, and the issue of disputed communication origins. One paper notes that intervention programs for stuttering produces mostly short-term benefits. The paper discusses the known risks of relapse following the end of stuttering therapy and the independent variables that influence this risk. Another paper examines voice quality in terms of perceptual, acoustic, and physiologic features of the different voice modes. By using the "Black Box" model, in which frequency, intensity, laryngeal waveform, pharyngeal prefiltering, and formant frequency can be controlled, the paper shows that a measure of interaction among all the controls exist. For example, a voice mode represented by a laryngeal waveform and pharyngeal prefiltering still interacts with frequency and intensity. Therefore, knowledge of the differences in physiology that attend to each voice mode can be valuable in effecting changes in voice production. The collection will prove valuable for linguists, speech therapists, neurologists, neuropsychologists, neurolinguists, speech pathologists, or investigators whose works involve linguistics, learning, communications, and syntax.
Wenner-Gren Center International Symposium Series, Volume 36: Speech Motor Control covers the papers presented at an interdisciplinary conference on Speech Motor Control, held at the Wenner-Gren Center in Stockholm on May 11 to 12, 1981. The book focuses on the methodologies, approaches, processes, and techniques employed in speech motor control. The selection first offers information on the interdisciplinary challenge of speech motor control and analogies between central motor programs for speech and for limb movements. Discussions focus on regulation of cerebral motor cortex output by afferent input, goal-orientation and voluntary movement, interaction of transcortical and segmental reflexes, plasticity of speech gestures, and the task of the speech motor system. The text then takes a look at speech production mechanisms in aphasia and functional landscapes in the cerebral cortex related to speech, as well as motor errors and phonetic transcription studies and correlational analysis of consonant preferences in infants, languages, and aphasic errors. The publication ponders on functional landscapes in the cerebral cortex related to speech; comment on the partial roles of the cerebral hemispheres for speech; and speech breathing kinematics and mechanism inferences. The text also ponders on the aspects of voice production and motor control, vocal fold kinesiology, and oral mechanoreceptors. The text is a dependable reference for readers interested in speech motor control.
Learning, Speech and Thought in the Mentally Retarded contains the proceedings of Symposia 4 and 5 held at the Middlesex Hospital Medical School in London on October 31, 1969 and March 20, 1970, respectively, under the auspices of the Institute for Research into Mental Retardation. This monograph presents topical problems in mental retardation, with emphasis on learning processes, speech, and thought. The application of operant learning techniques to the development of language in the retarded is highlighted. This book is comprised of four chapters and begins by outlining directions in research on learning deficits, followed by a discussion on teaching processes in the care of severely retarded children. The next chapter deals with speech and thought in the mentally retarded, with particular reference to two basic problems: the relative priority of language or thought and the selection processes underlying language. The final chapter explores language delay and language deviation in mentally retarded children. Throughout the book, the focus is on language: its nature, its development in the constitutionally normal and handicapped, some theoretical controversies among experts in this field, and the development of appropriate techniques for teaching language to the mentally retarded. This monograph will be useful to psychologists and clinicians working in the field of mental retardation.
With chapters containing up to 50 percent new coverage, this book provides a thorough update of the latest research and development in the area of acquired aphasia. Coverage includes the symptoms of aphasia, assessment, neuropsychology, the specific linguistic deficits associated with aphasia, related disorders, recovery, and rehabilitation. This comprehensive compilation, written by some of the most knowledgeable workers in the field, provides an authoritative text and reference for graduate students, clinicians, and researchers.
This volume combines the classical fields of perception research with the major theoretical attitudes of today's research, distinguishing between experience- versus performance-related approaches, transformational versus interactional approaches, and approaches that rely on the processing versus discovery of information. Perception is separated into two parts. The first part deals with basic processes and mechanisms, and discusses early vision and later, yet still basic, vision. The second covers complex achievements with accounts of perceptual constancies and the perception of patterns, objects, events, and actions.
