Predictors of postoperative language outcome in epileptic patients undergoing anterior temporal lobectomy
Characterization of mixed cases of aphasia, the most commonly attested in clinical practice.
Comparison of measurements at the sentence, word, and inflectional levels.
Group and single case comparisons.
The present study aims to contribute to the ongoing discussion about the impact of discourse-linking deficits on the performance of individuals with aphasia by providing new data from a set of rarely investigated constructions: sentences in which a clitic pronoun coexists alongside with the full DP it agrees with. To do so, we use data of individuals with non-fluent aphasias who need to overcome the difficulties in direct object (accusative) clitic production. This results in overproduction of non-target clitic right dislocations (RDs) and clitic doubling (CD). Data from 15 individual’s native speakers of Spanish and Catalan are discussed. Data complement the results of previous investigations on discourse-linking effects in these languages, allowing the interpretation of results across constructions.
The present work is dedicated to the role of gestures in overcoming lexical access problems in patients with motor aphasia. The study is based on a corpus of narratives by brain-damaged individuals – «Russian CliPS» (Clinical Pear Stories), the videos from which were annotated in the linguistic annotator «ELAN», with the gestural layout included in the analysis. The results suggest that most often the difficulties with lexical access were related to the search for nouns and verbs, and gestures (deictic and rhythmic gestures, beats) facilitated lexical access in patients.
Currently there is a need for standardized language assessment test in Russian. Our group has developed Russian Aphasia Test (RAT) based on modern psycholinguistic models and psychometric principles, taking into account existing standardized tests in other languages. RAT allows to separately assess each level of linguistic processing: from phonemic perception to discourse. Here we present the design of the test and the first results of its approbation in groups of neurologically healthy participants and individuals with aphasia. Preliminary results demonstrated that the test is sensitive to language deficits and their severity. Thus, RAT is a practical instrument for language assessment in aphasia which can be used both in clinical practice and for research purposes. At present test standardization in a large group of participants with and without aphasia is on-going with the goal of developing appropriate clinical and age norms.
