Linguistic analysis from the point of view of aphasic patients


In the project, we studied lexical access and syntactic analysis in language processing and the interaction between them. We employed the clinical approach, innovative for  Russian linguistics: patients with speech disorders, aphasias (fluent and non-fluent) were our experimental subjects in the project. For a more fine dissociation of lexical and syntactical levels of language processing, we chose eye-tracking method using the “Visual World” paradigm. The capacity for lexical analysis was checked in the task on dissolving lexical disambiguity, and for syntactical analysis - in the experiment on the understanding of syntax shuffles. 

          

We get the idea how healthy Russian speakers and aphasia patients employ and bring together lexical and syntactical levels of analysis: 
  1. Both groups of patients demonstrated lexical processing impairments, but in a different manner. Patients with non-fluent aphasia lexical access functions normally but with difficulties in resolving the lexical ambiguity. Patients with fluent aphasia have problems with lexical access, and lexical disambiguity problems are accompanied by repeated reactualization of the relevant meaning. 
  2. Both groups of patients had problems with syntax processing, but non-fluent patients gave their answers at the above chance level, while fluent patients’responses were erratic in nature. That is especially remarkable since traditionally syntax deficit is prescribed to non-fluent aphasia. 
  3. Verbal working memory capacity universally affects offline processing on both levels, syntactic and lexical. The syntactic level is also addicted to the memory factor in online processing, while online lexical processing is universally determined by ‘whether the subject had an aphasia and which one - fluent or non-fluent - and the speed of information processing.

For the first time, we demonstrated the impact of various non-linguistical factors in the success of the speech processing. The analysis of lesions localizations demonstrated the non-specific impact of left temporal and parietal cortex on both lexical disambiguity and complex syntax processing.
