The ''Preclinical Speech Science Workbook, Third Edition'' is a natural companion to the ''Preclinical Speech Science, Third Edition'' textbook, designed to help students integrate, apply, and go beyond the material presented in the textbook. The workbook contains a variety of activities, including anatomical labeling, measurement of physiologic and acoustic data, interpretation of graphs, and the conduct of simple experiments (without the need for special equipment). Comprehensive answers are also included for each chapter. The third edition of the workbook reflects the changes found in the textbook and includes activities to correspond with the three new textbook chapters on Auditory Anatomy and Physiology, Auditory Psychophysics, and Speech Physiology Measurement and Analysis, as well as revised content throughout the existing chapters. The activities in ''Preclinical Speech Science Workbook, Third Edition'' will help students begin to make the transition from traditional classroom and textbook learners to active participants in their development toward becoming speech-language pathologists and audiologists.
