Distribution of Language Measures among Individuals with and without Non-Fluent Aphasia

Existing studies report varied findings on the features that influence a non-fluent aphasia diagnosis, due to the numerous measurements and aphasia classifications available. This study applies Mann-Whitney U test to evaluate the distribution of 32 language measures among 78 individuals with and without non-fluent aphasia in the AphasiaBank corpus. The results highlight the different distribution of verbs, auxiliaries, and present participles between the two populations. Future studies will combine the results of this study with the measures speech therapist deem most informative, to generate a tool for visually synthesizing the AphasiaBank data.
