“…However, the finite verbs they use have a higher frequency and a lower diversity than the nonfinite verbs, whereas in the spontaneous speech of non-brain-damaged speakers (NBDs) diversity and frequency of finite and non-finite verbs do not differ (Bastiaanse, 2011). Still, in an experimental setting, people with fluent aphasia also show an impaired performance on verbs with past time reference compared to verbs with non-past time reference, which is however qualitatively different from that of agrammatic aphasic speakers Jonkers & de Bruin, 2009;Kljajevic & Bastiaanse, 2011;Wieczorek et al, 2011). Wieczorek et al (2011) trained two German speaking individuals with Broca's aphasia and two individuals with Wernicke's aphasia in tense and aspect production.…”

Background: Reference to an event's time frame can be accomplished through verb inflection. In agrammatic aphasia, a deficit in past time reference has been identified by Bastiaanse and colleagues (2011). In fluent aphasia, specific problems with this time frame (expressed by the past tense) have been found as well Jonkers & de Bruin, 2009). However, time reference does not always coincide with tense; in languages such as Dutch and English, reference to the past can be established by using past tense (e.g., "he wrote a letter") or a present tense auxiliary in combination with a participle, i.e., the present perfect (e.g., "he has written a letter"). Aims: The goal of this study is twofold. First, it aims to untangle tense problems from problems with past time reference through verb morphology in people with aphasia. Second, this study aims to compare the production of time reference inflection by people with agrammatic and fluent aphasia. Methods & Procedures: A sentence completion task was used to elicit reference to the non-past and past in Dutch. Reference to the past was tested through (1) a simple verb in past tense and (2) a verb complex with an auxiliary in present tense + participle (the present perfect). Reference to the non-past was tested through a simple verb in present tense. Fourteen agrammatic aphasic speakers, sixteen fluent aphasic speakers, and twenty non-brain-damaged speakers (NBDs) took part in this study. Data were analysed quantitatively and qualitatively. Outcomes & Results: NBDs scored at ceiling and significantly higher than the aphasic participants. Agrammatic speakers performed worse than fluent speakers, but the pattern of performance in both aphasic groups was similar. Reference to the past through past tense and [present tense auxiliary + participle] was more impaired than reference to the non-past. An error analysis revealed differences between the two groups.

“…Individuals with non-fluent aphasias have been found to overuse infinitives, or substitute the target tense by a present form. Reference to the past has been found to be significantly more impaired in these subjects than reference to the present (Zei and Šikić, 1990;Kljajević and Bastiaanse, 2011). Individuals with fluent aphasia also experience difficulties with the production of verb forms that refer to the past.…”

“…Individuals with fluent aphasia also experience difficulties with the production of verb forms that refer to the past. However, non-target responses consist of the correct time reference and the wrong selection of the verb form (Kljajević and Bastiaanse, 2011).…”

“…Interestingly, Kljajević and Bastiaanse (2011) address the issue of a possible dissociation between fluent and non-fluent aphasias. Using the Test for Assessing Reference of Time (TART, Serbian version: Kljajević and Bastiaanse, 2008), the authors investigate the production and comprehension of time reference in four Serbian-speaking individuals with fluent aphasia.…”

Deficits in word retrieval are commonly attested in aphasia. These have a major impact in verbs, especially after lesions causing the emergence of Broca's aphasia. Verbs are not only complex entities, but the core of the sentence, and constitute a central issue for both the proper understanding of language deficits, and assessment and recovery purposes. In this paper, we review the existing literature describing the speech of Serbian-speaking individuals with aphasia to explore the degree of preservation of verbal forms in this population. The role of different factors -such as the nature of the verb, its argument structure and the morphological markers attached to it -are discussed and contrasted in these lines against the multiple hypotheses proposed so far in the search for a unified explanation.

“…Namely, fluent aphasic patients produce fewer verbs in spontaneous speech than neurologically intact speakers (Bastiaanse et al, 1996;Edwards, 2002;Kim & Leach, 2004) and exhibit problems with verb retrieval (Bastiaanse & Jonkers, 1998;Kambanaros, 2008), access to argument structure and thematic representation of verbs (Russo et al, 1998), finite verb inflection (Varlakosta et al, 2006), and time reference through verb forms (Kljajevic & Bastiaanse, 2011). Thus, verb deficit is present in aphasia regardless of whether the lesion causing the disorder is located in the anterior vs. posterior cortical areas, or whether it runs cortically or cortico-subcortically.…”
