Filmed as received. UNIVERSITY MICROFILMS. ACKNOWLEDGMENTS The help of many people has made this study possible. Above all, I want to thank my adviser. Professor U s e Lehiste, whose insistence on clear formulation of ideas prevented me from tryinr many unworkable schemes. I also want to thank the members of my dissertation committee: Professors Catherine Callaghan, Gaberell Drachman, Arnold Zwicky, and, particularly, Neil Johnson. Preston Carmichael, technician, spent many hours helping me design and assemble instrumentation. I sincerely appreciate his help. Tom Whitney gave much assistance in devising and using computer programs for data processing. I thank him for his kind assistance. I also want to thank the Ohio Gtate University Instruction and Research Computer Center for permitting me to use their facilities. I am grateful to the "Phonetics Research Group"— Sara Games, Dick Gregorski, Linda Shockey, and Mary Wendell— for listening patiently to my problems and offering many helpful suggestions. I appreciate the help of all the members of the Ohio State University Linguistics Department who kindly served as subjects in many of these experiments. P’inally, I want to thank my family for their patience and moral support while I was writing this dissertation. This work was sponsored in part by the National Science Foundation through Grant GN-53^.1 from the Office of Science Information Service to the Computer and Information Science Research Center, The Ohio State University. 11 VITA September 1, 19^0 .
