Speech and Language

Speech and Language: Volume 4, Advances in Basic Research and Practice is a collection of papers that deals with the theories, clinical issues, and pathology of language and speech. Several papers discuss nonlinguistic and linguistic processing in children, phonological development in infants, and the development of speech fluency in children. Other papers examine the four major speech production models, the physiological and acoustical aspects of speech adaptation, spatial-temporal model of velopharyngeal function, and variations in the supraglottal air pressure waveform. One paper notes the relationships of two systems of development as follows: language development is dependent upon cognitive products and cognitive development is dependent upon language development. Such relationship leads to the hypotheses that language and cognitive developments are independent, are interdependent, and are both dependent upon some X abilities. One paper suggests that speech clinicians should have as a goal the achievement of speech that is as normal as possible in all respects, and not just for patients to sound normal. The collection will benefit linguists, ethnologists, psychologists, speech therapists, neurologists, neuropsychologists, neurolinguists, or speech pathologists.
