A Linguistic Classification of Phonological Paraphasias
To differentiate and compare normal speech errors (lapses, slips of the tongue) and aphasic (= pathological) phonological disturbances.
To differentiate phonological paraphasias produced by Broca’s, Wernicke’s and anomic aphasics (in the hope that phenomenological description can serve diagnostic and, albeit indirectly, therapeutic purposes; cf. Dressler, 1980b; Kotten, 1984).
To show how a phonological approach may contribute to a better un: derstanding of aphasic disturbances of sound structure, that is, to convince the reader that there is much more to phonology than is often thought. Phonology seems to be gravely underrated not only by neurologists, neuropsychologists, and speech therapists, but also by neurolinguists. Phonological concepts or criteria currently used are few and rather superficial; otherwise phonology is reduced to, and replaced by, phonetics (cf. Dressler, 1984a, b). The (interdependent!) relationship between phonetics and phonology will be discussed in the section on competence and in the conclusions; however, one example of this reductionism begins the section on the history of research.
