“…Thus, no evidence for CLEs was observed in the condition where it was expected. AF's results differ from the ones obtained in other language combinations which point to CLEs between similar syntactic structures either in production (Hartsuiker & Pickering, 2008;Verreyt et al, 2013a) or in comprehension (Ardila et al, 2000). Despite the fact that in the performance of this particular task, the presence of overt morphology (preposition a in Spanish and -k suffix in Basque) overrides word order and becomes the determining cue for the interpretation of questions and relatives in these DP-V-DP structures, our results suggest that the availability of the same morphological cue is not equally strong in the two languages (cf.…”

“…To start with, treatment in one language has been shown to lead to stable improvement in the untreated language, which can be considered an instantiation of a general cross-language transfer of therapy benefits (Ansaldo, Marcotte, Scherer & Raboyeau, 2008;Faroqi-Shah, Frymark, Mullen & Wang, 2010). Moreover, task-related and punctual crosslanguage influence has also been attested in priming studies, where it has been shown that hearing a sentence in one language can facilitate the production of a sentence with the same structure in another language (Verreyt, Bogaerts, Cop, Bernolet, De Letter, Hemelsoet, Santens & Duyck, 2013a). Similarly, cognate facilitation and interference effects observed in lexical decision tasks indicate that the language which is not used is also active and has an effect on the lexical processing of the other (Verreyt, De Letter, Hemelsoet, Santens & Duyck, 2013b).…”

Differential and selective morpho-syntactic impairment in Spanish-Basque bilingual aphasia

2014

This paper reports on the comprehension of movement-derived structures by a Spanish-Basque bilingual with chronic Broca's aphasia. The study reveals a differential impairment which affects mostly Basque and a selective impairment in this language that affects only object questions and subject relatives. The impairment pattern observed is discussed in light of the predictions made by different representational and processing accounts for (monolingual as well as bilingual) Spanish and Basque agrammatism.The asymmetry observed between the two languages suggests that the patient resorts to language-specific morpho-syntactic cues, which cannot be transferred from one language to the other because of the typological distance between Spanish and Basque. The data confirm results from previous studies showing that (major) typological distance hinders cross-language effects from arising in bilingual aphasia.

“…From the investigation of patterns of impairment and recovery in bilingual aphasics, he concluded that the mechanism of aphasia in a bilingual patient is due to increased inhibition, raised threshold of activation or unbalanced distribution of resources between the patient's languages after impairment rather than the physical damage to the whole language processing system. In addition, recent literature suggests that an impairment of cognitive control plays an important role in the development of bilingual aphasia and some of its impairment patterns. Furthermore, Fabbro assumed that symptoms of bilingual aphasia, when the mechanisms of their development, do not differ from the ones of monolinguals.…”

There is increasing evidence that a bilingual person should not be considered as two monolinguals in a single body, a view that has gradually been adopted in the diagnosis and treatment of bilingual aphasia. However, its investigation is complicated due to the large variety in possible language combinations, pre- and postmorbid language proficiencies, and age of second language acquisition. Furthermore, the tests and tasks used to assess linguistic capabilities differ in almost every study, hindering a direct comparison of their outcomes. Behavioral, electrophysiological, and neuroimaging data from healthy population show that the processing of second language domains (semantics, syntax, morphology) depends on factors such as age and method of acquisition, proficiency level and environment in which the second language was acquired. A number of single and multiple case reports that rely on behavioral testing of bilingual aphasics replicate these results. Additionally, they show that the patient's performance depends on the size and location of the lesion, as well as language typology and morphological characteristics. Furthermore, the impairment and recovery patterns and recovery generalization from treated to untreated language depend on the lexical and orthographic distances between the two languages. For healthy bilinguals, language processing is usually studied in comparison to monolinguals. We advocate that a good starting point for identifying patterns specific for bilingual aphasia is to compare patient studies of bilinguals and monolinguals.

“…However, it does not always result in successful sentence production (Saffran and Martin, 1997; Hartsuiker and Kolk, 1998; Marin and Schwartz, 1998; Cho and Thompson, 2010; Verreyt et al, 2013; Cho-Reyes et al, 2016). For example, Cho and Thompson (2010) found that although aphasic speakers show successful structural priming, reflecting structural planning, primed sentences contain a high rate of role-reversal errors, indicating faulty thematic mapping.…”

Introduction: Sentence production impairments in aphasia often improve with treatment. However, little is known about how cognitive processes supporting sentence production, such as sentence planning, are impacted by treatment.Methods: The present study used eyetracking to examine changes in sentence production resulting from a 12-week language treatment program focused on passive sentences (Treatment of Underlying Forms (TUF); Thompson and Shapiro, 2005). In two pre-treatment and two post-treatment sessions, nine participants with mild-to-moderate agrammatic aphasia performed a structural priming task, which involved repeating primed sentences (actives or passives) and then, using the same verb, producing sentences describing pictured events. Two individuals with aphasia performed the eyetracking task on the same schedule without intervening language treatment. Ten unimpaired older adults also performed the task to identify normal performance patterns. Sentence production accuracy and speech onset latencies were examined, and eye movements to the pictured Agent and Theme characters were analyzed in the first 400 ms after picture onset, reflecting early sentence planning, and in the regions preceding the production of the sentence subject and post-verbal noun, reflecting lexical encoding.Results: Unimpaired controls performed with high accuracy. Their early eye movements (first 400 ms) indicated equal fixations to the Agent and Theme, consistent with structural sentence planning (i.e., initial construction of an abstract structural frame). Subsequent eye movements occurring prior to speech onset were consistent with encoding of the correct sentence subject (i.e., the Agent in actives, Theme in passives), with encoding of the post-verbal noun beginning at speech onset. In participants with aphasia, accuracy improved significantly with treatment, and post-treatment (but not pre-treatment) eye movements were qualitatively similar to those of unimpaired controls, indicating correct encoding of the Agent and Theme nouns for both active and passive sentences. Analysis of early eye movements also showed a treatment-induced increase in structural planning. No changes in sentence production accuracy or eye movements were found in the aphasic participants who did not receive treatment.Conclusion: These findings indicate that treatment improves sentence production and results in the emergence of normal-like cognitive processes associated with successful sentence production, including structural planning.
