“…Similar results were obtained for aphasic speakers of Catalan and Spanish (Martínez-Ferreiro and Bastiaanse, 2013). In a study involving Swahili-English agrammatic aphasic bilinguals, however, participants were selectively impaired in the past condition of the TART only (Abuom and Bastiaanse, 2013). These results suggest that for IWAs, the complexity of discourse linking leads to errors in past time reference comprehension, whereas accuracy is higher for present.…”

“…Furthermore, the offline comprehension subtest of the TART (Bastiaanse et al, 2008) was administered, which has been used in previous studies (e.g., Abuom and Bastiaanse, 2013;Bastiaanse et al, 2011;Martínez-Ferreiro and Bastiaanse, 2013) and has items for past, present and future.…”

“…The original TART is contrasting the past target only with the present. This design was alternated to increase comparability with the eyetracking experiment while remaining comparability with previous TART studies (e.g., Abuom and Bastiaanse, 2013;Bastiaanse et al, 2011;Martínez-Ferreiro and Bastiaanse, 2013). Every sentence was presented auditorily and consisted of three constituents: the subject (man or woman), the verb and the object.…”

“…Several accounts for the problems with tense inflections exist, but recently, the role of the time frame to which is referred -with either tense inflection or other verb forms -has been highlighted. More specifically, verb forms that refer to the past are impaired in agrammatic aphasia, both in production and comprehension (Abuom and Bastiaanse, 2013;Bastiaanse et al, 2011). Based on an extensive data set of aphasiological production and comprehension, the PAst DIscourse LInking Hypothesis (PADILIH; Bastiaanse et al, 2011;Bastiaanse, 2013) was formulated to describe the pattern of selective impairment of past time reference.…”

“…The pattern of performance in both languages was parallel. In our second study (Abuom & Bastiaanse, 2013), agrammatic speakers were tested on production and comprehension of verb forms referring to the past, present and future, using both sentence completion and sentence-picture matching tasks. Their performance showed a selective deficit of reference to the past on both comprehension and production tasks.…”

For this study, sentence comprehension was tested in Swahili-English bilingual agrammatic speakers. The sentences were controlled for four factors: (1) order of the arguments (base vs. derived); (2) embedding (declarative vs. relative sentences); (3) overt use of the relative pronoun "who"; (4) language (English and Swahili). Two theories were tested: the Trace Deletion Hypothesis (TDH; [Grodzinsky, Y. (1995). A restrictive theory of agrammatic comprehension. Brain and Language, 50, 27-51]) that assumes a representational deficit in agrammatic aphasia and the Derived Order Problem Hypothesis (DOP-H; Bastiaanse & Van Zonneveld, 2005), which is a processing account. Both theories have the same predictions for sentences in derived order. The difference is that the TDH predicts chance level performance for sentences in which the arguments are not in base order, whereas the DOP-H predicts poorer performance when processing demands increase. The results show that word order influences performance, in that sentences in which the arguments are in derived order are harder to comprehend than sentences in which the arguments are in base order. However, there is a significant interaction with the factor "embedding": sentences with an embedding are harder to comprehend than simple declaratives and this influence is larger in derived order sentences. There is no effect of language nor of the use of a relative pronoun. These results are correctly accounted for by the DOP-H.

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.
