Interaction of language and memory
More and more studies in modern aphasiology point out that cognitive non-language deficiencies, such as disturbances of attention, memory, speed of information processing, and executive functions, accompany language disturbances traditionally seen in aphasia. Patients with aphasia make more errors, than the language norm when they have to switch between two tasks (even if one of these tasks is non-linguistic) or complete a task in the situation of constant interference. Overall experimental data demonstrates that the more voluntary attention is needed, the lower the results of subjects with aphasia in completing linguistic tasks. A number of studies demonstrate negative influence of small short-term memory and working memory span on language processes, especially comprehension in patients with aphasia. Thus current research data points out that language disorders in aphasia are accompanied by cognitive non-language disturbances that make significant contribution to difficulties in language information processing in patients with aphasia and that exacerbate their language deficit.
Fundamental scientific problem this study is based on is revealing and studying the role of memory components in language processes and clarification of psychological and neuroanatomical organization of interaction of these two cognitive functions in the norm and patients with local brain pathology.
