| Abstract | Here, we report a case of a 35-year-old right-handed woman with amnestic aphasia who failed to retrieve words but could correctly identify the number of moras and length of each word. Magnetic resonance imaging showed a hemorrhagic infarction in the left middle temporal gyrus, which was the result of a hematoma that was removed. At the time of neuropsychological assessment, her main symptom of aphasia was word-finding difficulty. In oral naming tasks, she mainly responded with "no response" or the use of verbal paraphasias, due to her word-finding difficulty. She showed unique responses, suggesting that she was able to correctly recall some features of the target words, such as the prosody and number of moras. That is, even if she could not find a target word, she often correctly answered whether the length of the target word was short or long and how many moras it had. Additionally, her responses included formal paraphasias and mixed paraphasias that were phonologically related to the target words and had the same numbers of moras as the target words. These findings suggest that the process of naming words includes the selection of the number of moras, the length of the word, and the retrieval of related phonemes. |
