Such deficit is a characteristic feature of so-called semantic aphasia. The impaired comprehension of semantically reversible constructions in those patients can be explained by a disorder of the common spatial neuropsychological factor grounded in the temporal-parietal-occipital (TPO) regions of the brain.Aims: The aim of the present study was to experimentally test the possibility that individuals with semantic aphasia experience specific difficulties in extracting spatial relations from a linguistic form and rely instead on basic sensorimotor stereotypes to interpret reversible linguistic constructions.Methods \& Procedures: Six individuals with semantic aphasia, 12 people with motor aphasia, 12 people with sensory aphasia, and 12 non-brain-damaged individuals performed a sentence-picture matching task; all participants were native speakers of Russian. Two types of reversible sentences were tested, each representing a direct and an inverted word order: prepositional (The boy is putting the bag in the box vs. The boy is putting in the box the bag) and instrumental (The grandmother is covering the scarf with the hat vs. The grandmother is covering with the hat the scarf). Irreversible sentences (The boy is putting the apple in the bag) served as control stimuli.Outcomes \& Results: Each group of participants performed better on irreversible than on reversible sentences. Within reversible sentences, an interaction between word order and construction type was found in individuals with semantic aphasia only. They performed more accurately in prepositional constructions with direct word order and in instrumental constructions with inverted word orderboth are related to sensorimotor stereotypes reflecting interaction with objects in the real world. Although no such clear dissociation was found in other aphasia types, correlation analysis revealed the same effect in some participants with motor and sensory aphasia.Conclusions: The findings confirm the importance of situational context for linguistic processing. First, if knowledge of the real world supports the unique interpretation of grammatical markers, it enhances processing in all tested cohorts of participants. Second, people with semantic aphasia consistently use sensorimotor stereotypes to compensate for their linguistic deficits. Since this was also found in some participants with other aphasia types, such a sensorimotor strategy might depend not on the damage to TPO areas as such, but on the intactness and overuse of left premotor regions suggested to be critical for motor and symbolic sequential processing.}, language = {en} } @article{MalyutinaDragoyIvanovaetal.2016, author = {Malyutina, Svetlana and Dragoy, Olga V. and Ivanova, Maria and Laurinavichyute, Anna and Petrushevsky, Alexey and Meindl, Thomas and P{\"o}ppel, Ernst and Gutyrchik, Evgeny}, title = {Fishing is not wrestling: Neural underpinnings of the verb instrumentality effect}, series = {Journal of neurolinguistics : an international journal for the study of brain function in language behavior and experience}, volume = {40}, journal = {Journal of neurolinguistics : an international journal for the study of brain function in language behavior and experience}, publisher = {Elsevier}, address = {Oxford}, issn = {0911-6044}, doi = {10.1016/j.jneuroling.2016.03.002}, pages = {37 -- 54}, year = {2016}, abstract = {Previous clinical research has shown a positive effect of instrumentality on verb retrieval in individuals with aphasia. Performance on instrumental verbs incorporating an obligatory tool into their conceptual representation (e.g., to cut) is more accurate compared to non instrumental verbs (e.g., to tear), possibly due to more specific conceptual representations of instrumental verbs. Seeking the neural correlates of the differences between instrumental and non-instrumental verbs, we conducted an fMRI study with 16 German speakers who performed a verb-object matching task with instrumental and non instrumental verbs. We found that an extensive neural network. including but not limited to frontal and temporal language-related areas was more involved in the semantic processing of non-instrumental compared to instrumental verbs. We argue that this reflects a greater load associated with the processing of less semantically structured/restricted representations of non-instrumental verbs. The unavailability of additional neural resources needed for the processing of non-instrumental verbs in individuals with aphasia may lead to better behavioral performance on instrumental than non instrumental verbs.
