     We examined 38 fluent aphasic and 42 nonfluent aphasic patients with respect to paraphasic responses by naming tasks. Our main points of focus and results were as follows :
    1) Fragmentary syllables and interruption, which should be separated from literal paraphasia, were proposed as independent categories of paraphasic response. The results obtained concerning the correlation justified the separation of these two categories.
    2) The occurring frequencies of verbal and literal paraphasias, which were defined in as narrow a sense as possible, were not significantly different between fluent and non-fluent groups. These results suggest that verbal and literal paraphasia might be the common and universal factors in the aphasic phenomena.
    3) However, because the frequency of literal paraphasia in the NF group highly correlated with that of anarthria, it is possible that the nature of literal paraphasia is different between fluent and non-fluent aphasics. In that case, hypothesis 2) might become uncertain.
    4) Two verbal paraphasia predominant cases and two literal paraphasia predominant cases were selected. However, no clear common lesion could be found in both conditions.
    There were four anarthria predominant cases, two of which were the same as those of the literal paraphasia predominant. A distinction between anarthria predominant cases in the two sub-groups might be possible, one with deep sited lesions and the other with pre-and postcentral cortico-subcortical sited lesions.
