![]() It is therefore hypothesized that substitutional errors concerning sonority will occur in conduction aphasia, but not in Broca's aphasia. voice, labial), some are primarily motivated for phonological tasks. Although most features can be accounted for in articulatory terms (e.g. Some phonologists suggested that a distinction should be made between articulatorily based and phonologically based features. Despite the fact that the phonemic errors in these two aphasia types arise at different levels, they are hard to distinguish. Some Broca's aphasics also produce a considerable number of phonemic errors, due to a disorder in phonetic processing, namely, planning and executing the articulatory programs. These errors are assumed to be attributed to a breakdown in phonological processing, that is, in transforming the underspecified lexical-phonological form into a phonemic representation. Several explanations for these phenomena are discussed.Ībstract = "Conduction aphasia is characterized by the production of phonemic paraphasias. This hypothesis has been tested and the results show that conduction aphasics indeed produce significantly more sonority substitutions than Broca's aphasics, but that the latter group does produce a few sonority substitutions as well. ![]() ![]() Conduction aphasia is characterized by the production of phonemic paraphasias. ![]()
