Inspired by the work of the pioneers of Auditory-Verbal Therapy (AVT), this comprehensive book respectfully offers detailed, in-depth knowledge and insights about the science, research, and practice of AVT for current and future generations of AVT practitioners. Edited by world renown experts with contributions by a global cohort of authors, Auditory-Verbal Therapy: Science, Research, and Practice is highly relevant to today's community of practitioners of Auditory-Verbal Therapy (LSLS Cert. AVT), and to those who are working towards LSLS Cert. AVT certification. It is also an excellent resource for audiologists, speech-language pathologists, teachers of children who are deaf or hard of hearing, administrators, psychologists, cochlear implant surgeons, primary care physicians, social workers, and other allied health and education professionals. Although written primarily for practitioners, it will be a welcome resource for parents, family members, and other caregivers who love children who are deaf or hard of hearing, and for whom the desired outcomes are listening, spoken language, and literacy. The book is divided into five parts: Part I: Overview of AVT: Foundations and Fundamentals This section covers the philosophy, history, and principles of AVT, including outcome data, results of a new survey of LSLS Cert. AVT community on global practice patterns in AVT; information on auditory brain development, and evaluation of evidence-based and evidence-informed practice for the new decade. Part II: Audiology, Hearing Technologies, and Speech Acoustics for AVT This section covers audiology and AVT, hearing aids, implantable and hearing assistive devices, and in-depth speech acoustics for AVT. Part III: Developmental Domains in AVT This section covers the development of listening, three-dimensional conversations, speech, play, cognition, and literacy, as applied to AVT. Part IV: Auditory-Verbal Therapy in Action Here strategies for developing listening, talking and thinking in AVT are covered, including parent coaching, the AVT Session: planning, delivery and evaluation, music and singing, assessment and inclusion of "AVT children" in the regular pre-school. Part V: Extending and Expanding the Practice of AVT The final section includes information on children with complex hearing issues, children with additional challenges, multilingualism, children and families experiencing adversity, tele-practice, coaching and mentoring practitioners, and cost-benefit of AVT.
