“…This finding is also similar to that of a prior study showing (numerically) reduced accuracy of subject-relative clause comprehension in both PPA-G and PPA-L (Thompson et al, 2013). For the object-relative sentences, the PPA-G group also showed reduced response accuracy compared to the control participants, consistent with prior findings of noncanonical sentence comprehension deficits in PPA-G (Cooke et al, 2003;Wilson et al, 2010;Charles et al, 2013;Thompson et al, 2013;Kinno et al, 2017;but see Zimmerer et al, 2014). The PPA-L group also had impaired response accuracy relative to the control participants and were not statistically different from the PPA-G group.…”

“…Indeed, deficient comprehension of reversible noncanonical structures is often found in agrammatic aphasia after a stroke (Caramazza and Zurif, 1976;Grodzinsky, 1986;Love et al, 2008;Thompson et al, 2013). In agrammatic PPA as well, the comprehension of reversible noncanonical constructions is consistently reported to be impaired, across a variety of experimental tasks, including sentence-picture matching (Wilson et al, 2010;Charles et al, 2013;Thompson et al, 2013; but see Zimmerer et al, 2014), sentence-picture verification (Kinno et al, 2017), and visual sentence decision (deciding if the agent is male or female; Cooke et al, 2003).…”

Primary progressive aphasia (PPA) is a degenerative disease affecting language while leaving other cognitive facilities relatively unscathed. The agrammatic subtype of PPA (PPA-G) is characterized by agrammatic language production with impaired comprehension of noncanonical filler-gap syntactic structures, such as object-relatives [e.g., The sandwich that the girl ate (gap) was tasty], in which the filler (the sandwich) is displaced from the object position within the relative clause to a position preceding both the verb and the agent (the girl) and is replaced by a gap linked with the filler. One hypothesis suggests that the observed deficits of these structures reflect impaired thematic integration, including impaired prediction of the thematic role of the filler and impaired thematic integration at the gap, but spared structure building (i.e., creation of the gap). In the current study, we examined the on-line comprehension of object-relative and subject-relative clauses in healthy controls and individuals with agrammatic and logopenic PPA using eye-tracking. Eye-movement patterns in canonical subject-relative clause structures were essentially spared in both PPA groups. In contrast, eye-movement patterns in noncanonical object-relative clauses revealed delayed thematic prediction in both agrammatic and logopenic PPA, on-time structure building (i.e., gap-filling) in both groups, and abnormal thematic integration in agrammatic, but not logopenic, PPA. We argue that these results are consistent with the hypothesis that agrammatic comprehension deficits reflect impaired thematic integration.

“…Similarly, the verb morphology of passive lemma is auxiliary V Participle . Kinno et al (2017) report of comprehension difficulty by agrammatic patients with non-canonical sentence structures. They find agrammatic patients performing worse in non-canonical constructions, whereas, the performance accuracy with canonical sentences were not significantly different from normal age-matched subjects.…”

Investigating the Agrammatic Production of Canonical and Non-Canonical Sentences Cross-Linguistically

Research on agrammatism has revealed that the nature of linguistic impairment is systematic and interpretable. Non-canonical sentences are more impaired than those of canonical sentences. Previous studies on Japanese (Hiroshi et al. 2004; Chujo 1983; Tamaoka et al. 2003; Nakayama 1995) report that aphasic patients take longer Response Time (RT) and make more mistakes in producing non-canonical sentences compared to that of canonical sentences. The present research investigates the production impairments of canonical and non-canonical sentences cross-linguistically focusing on Bangla, Japanese, German and English aphasic patients. While Bangla, Japanese, German have relatively flexible word order, and hence allow freer phrasal movement, English exemplifies less freedom in word order patterns, and does not allow as much movement as the former three. We hypothesized that Bangla agrammatic patients would have more impairments in producing non-canonical sentences than those of canonical counterparts, while the production of canonical sentences is not completely devoid of impairments too. Primary data were collected from Bangla agrammatic patients, and secondary data from Japanese, German and English were exploited for cross-linguistic comparison. The findings show that Bangla agrammatic speakers have severe impairments in producing passive sentences, although the production of active ones are not completely devoid of impairments. The cross-linguistic comparison of the findings implies that the production of Bangla agrammatism tend to be similar to other agrammatic production and the production of non-canonical sentences are more difficult than those of canonical sentences cross-linguistically.

“…Previous studies have examined a variety of perspectives regarding aphasia, including assessments and interventions for rehabilitation [6,7,8] communication training [9,10,11] community support [12,13,14,15,16,17] verb and noun utterances and other languagerelated aspects [18,19,20,21] and computer and communication aids [22,23,24,25,26]. Aphasics tend to have reading, writing, listening, and speaking disabilities.…”

Analysis of behavior of adults with Aphasia in a community

Aphasia is a disorder involving the disruption of language ability owing to brain injury. Practical communication support tools for adults with aphasia have been proposed, some of which are used in therapy and daily communication. The recent development of specialized applications and information technology, especially tablet computers and other portable devices, can improve communication between adults with aphasia, their caregivers, therapists, and others. The present study aimed to identify the needs of adults with aphasia and caregiving family members concerning communication aids. This paper analyzes the behavior of adults with aphasia in a community to clarify the preliminary requirements of computerized communication aid in Japanese for aphasics and their caregivers. The study data were obtained through (1) responses to questionnaires conducted on aphasics and their caregiving family members and (2) a morphological investigation of aphasics in community-based rehabilitation training. The principal results can be summarized as follows: (i) adults with aphasia and their caregiving family members have dif􀅫iculty communicating in various situations in their daily lives; among these, the most serious issue is the ability to share the conditions of the adult with aphasia; (ii) the noun utterances of the participants were diverse in terms of the frequency and content of uttered nouns; and (iii) the verbs frequently uttered by the adults with aphasia were limited in number. Based on these 􀅫indings, the preliminary conceptual design of a computer-based communication support tool is discussed as follows: (a) in addition to language impediments, adults with aphasia are more or less paralyzed; however, portable tablet PCs incorporating communication support software represent a promising communication aid; and (b) since the tendencies of verb and noun utterances differed among the participants, at least two different types of communication software should be implemented on tablet PCs.
