Abstract. There is currently a great need for modern, standardized neuropsychological tests for language assessment in Russian speakers with aphasia. Our group is working on the development of the Russian Aphasia Test (RAT). Within the scope of this work, two subtests for single-word comprehension of nouns and verbs were developed considering contemporary models of language processing and principles of psychometrics. The task for both subtests was spoken word-to-picture matching. The subtests were normed on individuals with aphasia (n = 45) and a control group (n = 30). This resulted in the final set of 30 diagnostic trials for nouns and verbs matched on relevant psychometric properties which are sensitive to language impairments for both fluent and non-fluent types of aphasia. This set of trials will be included in the final version of the RAT.
There is a lack of modern quantitative language assessment tests in Russian, integrating neuropsychological and psychometric traditions, and allowing to specify the type and severity of linguistic deficits in individuals with different aphasia profiles. In response to these clinical and research needs, a novel standardized aphasia test – the Russian Aphasia Test (RAT) – is currently being developed.
According to the theory of dynamic and systemic organization of higher cortical functions (Luria, 2002), spatial impairments show themselves not only in perception (visual or tactile), but also in understanding of certain sentence types – the so-called ’logical-grammatical constructions‘. Testing these constructions is traditionally included in the neuropsychological diagnosis of semantic aphasia (Tsvetkova et al., 1981). The aim of this study was to design and standardize an enhanced diagnostic test, which would allow to more precisely detect the severity and the character of speech disorders in patients with semantic aphasia.
