THIS three-year period encompasses the end of a decade and a midcentury year. It also includes a period when many research projects started in the years of postwar expansion of higher education were brought to completion. It was a fruitful period as revealed by the bibliographies and the many areas of emphasis. Areas of greatest activity include voice science and experimental phonetics, group analysis of speech phenomena, discussion, listening, teaching materials, communication theory, and pro fessional educational problems. No attempt is made in this review to cover the work in speech and hearing disorders as this material is covered in the issue on special education. Three new journals were started during this period and others, particularly the regional journals, greatly expanded.
