To explore the discourse characteristics of anomic aphasia compared with healthy adults across three discourse tasks based on Mandarin AphasiaBank. Method. Multi-media samples of twelve anomic aphasia patients and twelve cognitively healthy adults across three discourse tasks (single picture, sequential pictures and story narrative) were collected from Mandarin AphasiaBank. By using CLAN, outcome measures were five discourse characteristic parameters (the number of utterances, mean length of utterance in words, lexical diversity using the moving average type-token ratio, words per minute and proposition density) and word category distributions across different discourse tasks. Results. A 2 × 3 mixed ANOVA revealed that there was no interaction between the groups and the discourse tasks. On the one hand, the main effect of group showed that the output of the other four discourse parameters (except the number of utterances) was significantly lower for the anomic aphasia group than the control group . On the other hand, the main effect of task revealed that the proposition density and the number of utterances in story narrative were both better than that in single picture and sequential pictures; the words per minute in story narrative was better than that in single picture description. T-tests revealed that the the anomic aphasia group had significantly fewer MATTR and words per minute in all three tasks compared to the control group. Different discourse tasks had different distribution patterns of word categories between groups. For the anomic aphasia group, there were significantly fewer nouns, verbs and adverbs in the sequential pictures, significantly more nouns, pronouns and prepositions in the single picture description, and significantly more pronouns but fewer prepositions in the story narrative. Conclusion. For the anomic aphasia group, the words per minute and lexical diversity were lower than that of the control group, across different discourse tasks. The characteristics of word categories across different discourse tasks obtained from patients with anomic aphasia could also be analyzed compared to the normal control group. These results provide a new perspective for evaluation and treatment of aphasia across discourse analysis based on Mandarin AphasiaBank.
