“…Bastiaanse et al (2011) found that past time reference was selectively impaired in both production and comprehension for both Turkish and English speakers with aphasia (see also Jonkers and De Bruin (2009) for Dutch; Yarbay Duman and Bastiaanse (2009) for Turkish). However, several studies have reported no significant differences between impairment in reference to the past, present, and future (Fyndanis et al, 2018(Fyndanis et al, , 2012Wenzlaff & Clahsen, 2004). Fyndanis et al (2012), investigated the ability of two Greek-speaking agrammatic individuals to produce tense and aspect by means of transformational sentence completion tasks: the participants were asked to make a transition from one (sample) time reference (i.e., Tomorrow you will wash your hair) to another time reference on the basis of a temporal adverbial cue (i.e., Yesterday you .…”

An investigation of time reference in production and comprehension in Thai speakers with agrammatic aphasia

2020

Background: It has been demonstrated that reference to the past is difficult for individuals with agrammatic aphasia, leading to the formulation of the PAst DIscourse LInking Hypothesis (PADILIH). Many of the previous studies have focused on Indo-European languages, in which time reference is expressed through verb inflection. The current study examined the PADILIH in Thai, a language that does not use verb inflection but instead uses aspectual markers to refer to time. Aims: We aimed to evaluate the pattern of impairment of time reference in Thai speakers with agrammatic aphasia, by investigating how grammatical reference to past, present, and future was processed. Methods and Procedures: A total of 15 Thai agrammatic speakers and 18 Thai non-brain-damaged (NBD) speakers participated in a sentence production task and an auditory sentence-to-picture matching comprehension task, both of which probed past, present, and future time reference. Outcomes and Results: While the NBD participants performed close to ceiling in both production and comprehension, the agrammatic speakers showed significantly more difficulty in conditions requiring reference to the future in both modalities. In production, however, the agrammatic speakers replaced the target future time reference construction with negation (a construction that can be used as an alternative means for future reference). When responses using negation were counted as correct, the individuals with agrammatic aphasia showed equal impairment across conditions. Conclusions: The results of this study were inconsistent with the PADILIH predictions: Thai agrammatic speakers experienced more vulnerability in reference to the future than the present and the past. This suggested that impairments of time reference may differ depending on the structure of the language. We hypothesized that the problems with producing future time reference in Thai may be influenced by the grammatical status of the future marker. In addition, the use of negation in place of the target word might have been because this negative construction reduces the processing load for Thai agrammatic speakers.

“…This is so because, to perform this task, participants had to both encode an abstract, prephonological feature (+PERFECTIVE or −PERFECTIVE) other than that encoded in the verb form of the SS, and to retrieve a corresponding verb form/inflection. Hence, our design does not allow us to detect the exact nature of the deficit in grammatical aspect that emerged in Greek MS. (For suggestions on how to tease apart encoding from retrieval processes, see Fyndanis et al, 2018a ).…”

Impaired Verb-Related Morphosyntactic Production in Multiple Sclerosis: Evidence From Greek

Background: A recent systematic review found that language deficits are not very common in individuals with multiple sclerosis (MS). However, there are significant gaps in our knowledge about language abilities in MS. For instance, morphosyntactic production has not been explored adequately thus far. This study investigated verbrelated morphosyntactic production in MS focusing on Greek, a morphologically rich language. Methods: A sentence completion task tapping into the production of subjectverb agreement, time reference/tense, and grammatical aspect was administered to 39 Greek-speaking individuals with MS [25 individuals with relapsing-remitting MS (RRMS group) and 14 individuals with secondary progressive MS (SPMS group)]. The task included only regular verbs. Generalized linear mixed-effects models were used to investigate the ability of individuals with MS to produce the above-mentioned morphosyntactic categories. Results: Overall, the RRMS and SPMS groups performed significantly worse than their matched control groups. Moreover, all four groups performed significantly worse on grammatical aspect than on subject-verb agreement and time reference. The difference between subject-verb agreement and time reference was not significant in any of the four groups. The overall performances of the RRMS and SPMS groups did not differ significantly.

Neurolinguistic Studies on the Linguistic Expression of Time Reference in Thai

The concept of time is crucial in everyday communication. Temporal expressions help us to understand when things happen, relative to when we are speaking. For instance, the sentence Last night, Jimmy talked to his grandmother shows that the event took place in the past. If Last night was to be replaced by Tomorrow, the sentence becomes ungrammatical, because the new phrase does not match the time frame specified by the verb talk. Time reference has been shown to be affected in individuals with acquired language impairment, such as agrammatic aphasia (e.g., Bastiaanse et al., 2011;Bastiaanse, 2013). Critically, there are many different ways to refer to time; for instance, by morphological markers such as the -ed in English and other Indo-European languages, by the use of tone such as in Akan (Tsiwah et al., 2020), and by aspectual markers (the use of free-standing morphemes to indicate different time frames) such as in Thai, the focus of the current dissertation. INTRODUCTIONAphasia, in Greek 'ἄφατος (áphatos)' from 'ἀ-(a-, not)' and 'φάσις (phásis, speech)' meaning 'no speech', is an acquired language disorder that affects linguistic abilities: the ability to produce and to comprehend (also to read and to write). It is usually caused by left-lateralized brain damage commonly from strokes, brain tumors, head injuries or dementia. Language severity varies individually: to exemplify, for some individuals, it may affect the ability to retrieve words, while for others, it may affect the ability to construct grammatical sentences, or to understand certain types of sentence (e.g., passive sentences and object clefts). Whether the production or comprehension modalities are affected depends on the size and the lesion site of the brain damage (Grodzinsky, 1990).Aphasia is broadly distinguished based on the characteristics of verbal expressions into non-fluent and fluent types (e.g., Davis, 2007;Goodglass & Kaplan, 1972). The focus of this dissertation is on non-fluent aphasia; specifically, agrammatic aphasia. Agrammatic speech is traditionally characterized by non-fluent speech output, with relatively intact comprehension of single words. Menn and Obler (1990) noted that, cross-linguistically, speech rate and utterance length are means of measurement used to define agrammatism.Compared to non-brain damaged (NBD) speakers, individuals with agrammatic aphasia produce slower speech with more simplified grammatical structures. Their connected speech is reported to consist mainly of content words (i.e., nouns, verbs, adjectives), while function words and grammatical morphemes are often omitted and substituted (e.g., Goodglass & Kaplan, 1972).
