“…In a study by Abuom et al syntax processing in 11 agrammatic (Broca) aphasics was studied using a sentence–picture matching test. During this test, the participant should match a verbally presented sentence to one of four pictures among which, besides the correct one, there was also a lexical distractor, a reverse role distractor and a picture that included both distractors.…”

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.

“…Notice that the DOP-H is a processing account: it assumes that derived order is more difficult than base order, but not that derived order is impossible, such as representational accounts like the Trace Deletion Hypothesis (e.g., Grodzinsky, 2000) suggests. The DOP-H focuses on word order in particular and is based on empirical findings across languages (for a review of the hypothesis, Abuom, Shah, & Bastiaanse, 2013).…”

The effect of syntactic frequency on sentence comprehension in standard Indonesian Broca’s aphasia

Background: Comprehension of reversible sentences that have derived word order has often been reported as impaired in agrammatic aphasia. Most accounts of this phenomenon refer to the syntactic differences between derived and base word order of the arguments. However, it has been demonstrated that in agrammatic spontaneous speech in standard Indonesian (SI) passives are produced at a rate that is proportional to that of healthy speakers. The main difference between passives in SI and in other languages is the frequency with which passives are used: passives in SI are highly frequent. The high frequency can be explained by the fact that passives are used for politeness reasons, saliency of the passive morphology, earlier acquisition, and formal simplicity of the passive structure. Aims: The purpose of the current study is to investigate comprehension of the passive as a derived structure in SI and the influence of frequency. Methods & Procedures: A sentence-to-picture matching task was developed to test four reversible sentence types (active, passive, subject cleft and object cleft). There are three variables that are of interest, that is, word order, embedding and relative frequency of structures. Eleven agrammatic speakers classified as suffering from Broca's aphasia were tested. Outcomes & Results: The passive sentences were comprehended equally well as the active sentences. Embedding had limited effects: subject clefts were understood as well as actives and passives. Object clefts, however, were understood poorly and significantly worse than the three other sentence types. Conclusions: The sentence comprehension deficit pattern shown in SI individuals with Broca's aphasia introduces frequency of a syntactic structure as an additional factor to consider. Whether frequency or pragmatic constraints protects against erosion of the passive in Broca's aphasia in SI remains an open question.

“…This calls for an integrative account in line with Abuom, Shah, and Bastiaanse's (2013) who proposed that these factors are key to define the complexity of an utterance. Passive sentences are consistently found to be more impaired than actives in the languages under investigation (Bastiaanse et al, 2002;Benedet et al, 1998;Beretta et al, 2001;Gavarró & Dotti, 2014;Gavarró & Romeu, 2010;Juncos-Rabadán et al, 2009;Martínez-Ferreiro et al, 2014;Miera & Cuetos, 1998).…”

Non-fluent aphasia in Ibero-Romance: a review of morphosyntactic deficits

2014

View full text Add to dashboard Cite

Background: Castilian-Spanish, Catalan, Galician, and European Portuguese are the most widely spoken languages of the Ibero-Romance group. An increasing number of authors have addressed the impact of aphasia on the morphosyntax of these varieties. However, accurate linguistic characterisations are scarce and the different sources of data have not been yet compiled. Aims: To stimulate state-of-the-art research, we provided a comprehensive summary of morphosyntactic aspects of Ibero-Romance and a review of how these are affected in non-fluent aphasia. The topics we dealt with are the use of verb argument structure and morphology, sentential negation and word order, definite articles, personal and reflexive pronouns, passives, topicalised constructions, questions, and relative clauses. Methods & Procedures: An exhaustive fieldwork and search of PubMed, Web of Science, and Medline records were performed to retrieve studies focused on morphosyntactic issues concerning the Ibero-Romance varieties. A total of 27 studies produced by 46 authors of varying background emerged. We did not review studies of category-specific deficits and aspects related to bilingual aphasia, although we assume that most speakers of Galician and Catalan are bilingual. Studies of spontaneous speech were included when no controlled experimental tasks were available. Outcomes & Results: The morphosyntactic commonalities of Ibero-Romance have been tackled from different theoretical perspectives. There exist asymmetries in findings which we explain with the use of different tasks (and task complexity) and individual differences between participants. Conclusions: Discourse-linking factors as well as deviations from the canonical pattern are recurrent answers to these asymmetries. A comprehensive theory of impairments in non-fluent aphasia integrating relevant aspects of both structural and processing accounts seems necessary.
