Case-assignment by prepositions in Russian aphasia

12 November 2009

Maria Trofimova investigated linguistic abilities of fluent and non-fluent aphasic speakers who suffer form a language disorder that usually results from a brain injury to the left hemisphere (e.g., a stroke). The project included a series of experiments to investigate case assigning abilities by prepositions of aphasic speakers of Russian – morphologically rich language which main properties make it particularly interesting for research of case. Narrative speech of non-fluent aphasic speakers was found to be impoverished with respect to prepositions, which was not observed in the speech of fluent aphasic speakers. However, the informal conversational style of the narrative data acquisition could have allowed non-fluent aphasic speakers to avoid using those constructions (such as prepositional phrases) and elements (prepositions) that are problematic for them. Therefore, Trofimova examined further both groups of aphasic speakers in experimental settings where they were driven to use prepositions and prepositional phrases. The experiment showed that production of prepositions and complete prepositional phrases was problematic for fluent as well as for non-fluent aphasic speakers. With respect to case marking, Trofimova observed that when both groups of aphasic speakers produced a correct case-assigning preposition they also managed to produce correct case-marking morpheme on its complement noun. Therefore, presence of correct case-assigning prepositions was found to have a positive effect on production of correct case-marking morphemes. Further experiment showed that this was true for all case-assigning prepositions independently of the function they performed in the experimental stimuli or the context in which they occurred.
