When “macrocefalo (macrocephalous)” is read “minicervello (minibrain)”: Evidence from a single case study

We report the case of a patient who showed a marked deficit in compound reading after almost complete recovery from his aphasic disturbances. Omission of one of the two compound components was his most frequent type of error. The patient also produced many paraphasias, which always respected the compound structure of the target. Similar errors were found on tasks of naming and writing to dictation. A deficit in retrieving the verb component of verb-noun compounds was also observed, consistent with the patient's residual agrammatism, and with decomposition at some point in processing. We suggest that this pattern of performance is compatible with a dual route model that hypothesises two stages of compound retrieval, a whole word stage followed by a decomposition into two constituent morphemes.
