ABSTRACT
Recent years have heralded increased activity in the disciplines concerned with human speech. The most notable impact has been made by the linguists and psycholinquists (see Berko, 1958; Chomsky, 1957; Fraser, Bellugi & Brown, 1963; Ervin, 1964). In psychology, human speech has been investigated by steadily increasing numbers of workers since the turn of the century. The psychologist’s activities have evolved into several discrete categories that are delineated by methodology. These categories can be identified with the labels of verbal learning, language development, and, more recently, verbal conditioning.
