Abstract Using the triangle model's perspective that naming is the result of interaction between semantics and phonology, an anomic aphasic patient, TK, was evaluated for his semantic and phonological ability longitudinally, and also for his naming ability - one month to five months post onset of brain infarction. Two picture-naming experiments, in which stimuli were manipulated and controlled by word properties, were conducted. TK showed i) co-occurrence in improvement of phonological function and naming ability, ii) marked benefit from the use of phonological cueing resulting in disappearance of semantic paraphasia, iii) the impact of phonological cueing became more powerful with increased recovery from impairment, iv) semantic category effect (man-made objects>living things) was observed until two months post-onset, and v) a word frequency effect on picture naming consistently. These results suggested that TK's naming disorder was caused by phonological impairment and it was improved due to reactivation of fragile phonological representation. Cognitive models were used to try to explain TK's naming disorder and recovery processes, and some empirical and clinical implications were discussed.
