Tense processing in Broca's and Wernicke's aphasia

Aspects of time: Time reference and aspect production in Russian aphasic speakers

“…The observed similarities between the performance of non-fluent and fluent aphasic speakers are in line with findings of Jonkers and Bruin (2009) and Wieczorek, Huber, and Darkow (2011), who suggest that the ability to provide time reference by verb forms is not only compromised under the condition of left frontal brain damage (often causing non-fluent aphasia). And although information about lesion sites of aphasic speakers who participated in the present study is not available, this claim is not based solely on the assumption about the classical relationship between lesion sites and aphasia syndromes (frontal lesions being related to the non-fluent aphasia, posterior lesions leading to fluent aphasia).…”

“…These problems with finite verbs suggest that a specific past time reference deficit may be expected in fluent aphasic speakers too. In another Dutch study, Jonkers and Bruin (2009) demonstrated that fluent speakers with Wernicke's aphasia experience more problems when producing past tense than when producing present tense. It is not known, however, whether non-fluent and fluent aphasic speakers perform similarly regarding aspectual characteristics of the verb and interaction of time and aspect.…”

Finite verb inflections for evidential categories and source identification in Turkish agrammatic Broca's aphasia

“…The left prefrontal cortical lesions, including lesions in Broca's area and its surrounding connections, have been identified to lead to impairments in production of grammatical and functional categories (Badecker and Caramazza, 1986;Bastiaanse et al, 2002;Clahsen and Ali, 2009;Faroqi-Shah and Thompson, 2007;Jonkers and de Bruin, 2009;Nanousi et al, 2006, and many others) and in source memory Johnson, 2000, 2009, for reviews). The current study has shown that both production of evidential categories and source identification are affected in individuals with agrammatic aphasia, albeit the contrasting direction of the errors.…”

“…Their data showed that past tense/perfect aspect 1 is more impaired than future tense/imperfect aspect. Jonkers and de Bruin (2009) demonstrated that the selective deficit for past tense is not restricted to production but also holds for comprehension in Dutch Broca's and Wernicke's aphasia alike. These studies led to the idea that it is not tense but reference to the past through verb inflection that is selectively impaired in agrammatic aphasia.…”

Losing track of time? Processing of time reference inflection in agrammatic and healthy speakers of German

“…Furthermore, a yes-bias, often exhibited by people with aphasia, poses a problem for interpreting the data of a grammaticality judgment task but is not an issue in sentencepicture matching tasks. Jonkers and de Bruin (2009) showed that Dutch-speaking IWAs were more impaired in interpreting past tense inflection than present tense inflection. Bastiaanse et al (2011) studied agrammatic comprehension of time reference using the sentence-picture matching task of the Test for Assessing Reference of Time (TART; Bastiaanse et al, 2008).…”
