A longitudinal study is reported of the conversational speech of a neologistic jargon aphasic patient, P.Z., at four sampling dates, from 3 months to 3 yr post trauma. The incidence of neologisms in conversational speech declined sharply in the first 10 months. However, while naming improved during this period, active speech vocabulary became smaller. Analyses of vocabulary, pauses and neologisms, along with other tests of linguistic ability, indicate that the changes in speech should be attributed to modifications in speech strategies rather than to functional recovery. The implications of these findings for the interpretation of the evolution of jargon and the value of longitudinal studies of aphasia in distinguishing functional recovery from modification of strategies are discussed.
