Abstract
-
This dissertation addresses the following questions: (1) Given a dissociation between sound and meaning, what will be the phonological properties of speech? (2) Will those properties be fixed or will they change depending upon whether the aphasic is engaged in a dialogue, producing a lengthy uninterrupted flow of jargon, or reading from written text? (3) Will longitudinal observations provide evidence of recovery toward meaningful speech?;The results of the investigation may be summarized as follows: (1) KS produces virtually all of the sounds of normal English and German; (2) While, overall, the frequency distribution of sounds in his jargon is significantly correlated with the distribution found for normal speakers, in terms of individual phonemes, the two distributions differ largely due to a greater than expected proportion of labials in the jargon; (3) Across samples, the jargon is characterized by a stereotypic, repetitious quality attributable to the consistent preference for /r/ and /s/ among consonants and /a/ among vowels; (4) Units of production tend to be initiated and terminated by central consonants. In vowel clusters, there is a transition from low back to high front. For consonant clusters the sequence is typically a centrally articulated stop followed by a centrally articulated fricative. Manner tends to change across consonant clusters, while voicing remains the same. Thus, the most common consonant cluster is a voiceless stop followed by a voiceless fricative. In CV cluster, central consonants are followed by back vowels; in VC clusters, back vowels are followed by central consonants; (5) The jargon elicited on reading tasks essentially conforms to the pattern found in spontaneously produced jargon, indicating a single sterotyped mode of production; (6) Over a period of 2 1/2 years, the fixed distributional properties of the jargon do not change. Indeed, there is an appearance of greater homogeneity of the jargon at Time 2 in that the phoneme frequency distributions of samples obtained at the end of the 2 1/2 year period are more similar to one another than samples obtained at the beginning of that period.;The jargonaphasias provide insight into the relationships among levels of representation of linguistic knowledge and particularly into the nature of the translation from a representation of meaning into a representation of sound. For they are assumed to indicate the level of representation which is translated into sound in that particular form of jargonaphasia. In phonemic jargonaphasia, where sequences of sounds transmit no linguistic meaning, the cognitive differentiation of a representation of meaning into a representation of sound cannot take place. Phonemic jargonaphasia thus points to the fundamental independence of a semantic level from a phonological level of language and furthermore, indicates those properties of the phonological code which are fundamental to the sound structure of normal language.
