This paper proposes an understanding of agrammatism from the perspective of a recent usage-based theory of grammatical status, the ProGram theory (Boye and Harder, 2012). According to this theory, grammatical elements have two central properties: they are by convention discursively secondary (i.e. attentional background) and dependent on combinatio...
Article
Background: Word retrieval skills change across the lifespan. Permanent alterations in the form of decreased accuracy or increased response time can be a consequence of both normal ageing processes or the presence of acquired and neurodegenerative disorders (e.g., aphasia and dementia). Despite the extensive literature exploring the neuroanatomica...

Full-text available
Background Outcome measurement is recommended in stroke clinical practice guidelines, however there is considerable variability in how this activity is performed in clinical practice. Factors driving clinician behaviour have been explored in English-speaking countries, but little is known about the factors influencing clinical practice in non-Engli...

Coordination of international aphasia research would minimise duplication of effort, support synergistic international activities across languages and multidisciplinary perspectives, and promote high-quality conduct and reporting of aphasia research, thereby increasing the relevance, transparency, and implementation of findings. The Collaboration o...
Article
Full-text available
Pronouns constitute a heterogeneous class of linguistic elements, allowing for expression of referential relationships. Pronouns have an important place in daily communication which speakers and listeners rely heavily on for. Aphasia literature has evidenced that pronoun processing is impaired in people with aphasia (PWA), although explanations und...

This volume, the third in the series Studies in Language and Mind, contains selected papers presented at the 6th and 7th Novi Sad workshop on Psycholinguistic, neurolinguistic and clinical linguistic research, held at the University of Novi Sad in April 2018 and 2019. The current volume contains six chapters – five research papers and a squib – org...
Article
Full-text available
Background: Languages of the world have several ways of expressing time reference. Many languages such as those in the Indo-European group express time reference through tense. Languages such as Chinese and Standard Indonesian express time reference through aspectual adverbs, while Akan does so through grammatical tone. Previous studies have found...
Article
Full-text available
Background: The distribution of pronouns varies cross-linguistically. This distribution has led to conflicting results in studies that investigated pronoun resolution in agrammatic indviduals. In the investigation of pronominal resolution, the linguistic phenomenon of “resumption” is understudied in agrammatism. The construction of pronominal resol...
Article
Background: Polysynthetic languages can be roughly defined as languages which have an extreme morphological complexity. They present a range of challenges to linguistic and neurolinguistics theories that are based on standard average European languages. Yet, no studies exist on aphasia in such languages, and the communities that speak them have lit...

Article
Background: Functional and usage-based theories of language are gaining increasing influence in linguistics. These theories understand language structure as underpinned by domain-general neurocognitive capacities and as shaped by usage patterns and the function of language as a means for communication. Accordingly, they entail an approach to aphasi...
Article
The lexical-grammatical divide has been a widely addressed topic in aphasia. Speech parts are generally classified as either belonging to a lexical or a grammatical category based on the frequency of acquisition of new members in their paradigms (open vs. closed classes), thus neglecting heterogeneity within categories. Such an approach has led to...

Article
Full-text available
Imageability is a psycholinguistic variable that indicates how well a word gives rise to a mental image or sensory experience. Imageability ratings are used extensively in psycholinguistic, neuropsychological, and aphasiological studies. However, little formal knowledge exists about whether and how these ratings are associated between and within la...
Article
Full-text available
Comparative research on aphasia and aphasia rehabilitation is challenged by the lack of comparable assessment tools across different languages. In English, a large array of tools is available, while in most other languages, the selection is more limited. Importantly, assessment tools are often simple translations and do not take into consideration...
Article
The present study aims to contribute to the ongoing discussion about the impact of discourse-linking deficits on the performance of individuals with aphasia by providing new data from a set of rarely investigated constructions: sentences in which a clitic pronoun coexists alongside with the full DP it agrees with. To do so, we use data of individua...

The aim of this paper is to give an overview of research in the field of clinical linguistics focusing on several closely related South Slavic languages, namely Bosnian, Croatian, Montenegrin and Serbian (BCMS or Serbo-Croatian). It summarizes studies of genetic, developmental and acquired disorders conducted with participants who are native speake...
Article
Background: Comprehension of reversible sentences that have derived word order has often been reported as impaired in agrammatic aphasia. Most accounts of this phenomenon refer to the syntactic differences between derived and base word order of the arguments. However, it has been demonstrated that in agrammatic spontaneous speech in standard Indone...
Article
Despite their ample reading experience, higher education students with dyslexia still show deficits in reading and reading-related skills. Lateralized print tuning, the early sensitivity to print of the left parietal cortex signalled by the N1 event-related potential (ERP) component, differs between beginning dyslexic readers and controls. For adul...

Article
Observable disruptions in spontaneous speech are among the most prominent characteristics of aphasia. The potential of language production analyses in discourse contexts to reveal subtle language deficits has been progressively exploited, becoming essential for diagnosing language disorders (Vermeulen et al., 1989; Goodglass et al., 2000; Prins and...
Article
Introduction Classical attempts to capture the nature of aphasia have been “corticocentric” in identifying language processes. Recent conceptual and technical advances force us to reconsider the neural bases of language. In this work we aim to review several studies of damaged subcortical structures (thalamus and basal ganglia) that show large effe...

Дефицити у проналажењу речи једна су од карактеристика афазије. Они се у највећој мери очитују у категорији глагола, нарочито након оних лезија које резултирају настанком Брокине афазије. Будући да управо глаголи садрже саму срж реченице, истраживања везана за продукцију глагола код популације са афазијом од кључног су значаја не само за разумевање...
Article
Full-text available
Background: Castilian-Spanish, Catalan, Galician, and European Portuguese are the most widely spoken languages of the Ibero-Romance group. An increasing number of authors have addressed the impact of aphasia on the morphosyntax of these varieties. However, accurate linguistic characterisations are scarce and the different sources of data have not b...
Article
Full-text available
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 purp...
Article
The vulnerability of time reference, either marked by means of verbal morphology or by adverbs, has been established in an extensive array of languages in agrammatic aphasia. Recent studies (0045, 0270, 0325, 0285 and 0400; among others) have determined that far from being general, the observed deficit is sensitive to tense differences with a clear...
Article
Full-text available
Background: Morphological errors of tense and agreement are salient in agrammatic aphasia. The PADILIH predicts impairments in discourse linking that translate to greater difficulties in referring to a past event time than to a future or a present event time. In Catalan, the Periphrastic conditional tense (e.g., “if the man had had time, he would h...
Article
Background: Deficits in the production of complex structures have been widely documented in non-fluent forms of aphasia. Nevertheless, the data available on fluent deficits are scarcer. In both cases, reduced complexity is attributed to syntactic factors. In the related field of syntactic theory, there exist a number of studies on the production of...
Conference Paper
Full-text available
Cross-linguistic research on language pathologies has shown that production of clitic pronominals is problematic for patients with aphasia. The current contribution provides the first data on production of the unaccusative/middle clitic SE and considers how pronominal interpretation influences verb production. Two morphologically similar constructi...

Full-text available
This paper aims at examining whether grammatical errors produced by Broca’s aphasics are a consequence of a selective impairment of functional categories in three closely related Ibero-Romance languages — Catalan, Galician, and Spanish — for which almost no work had hitherto been done. In addition, a reinterpretation will be proposed under cartogra...

Article
Full-text available
This paper aims to characterise difficulties with the order VS in agrammatic speech. To fulfill this aim, we test the production of yes/no questions in 15 agrammatic subjects and 15 matched non-damaged control native speakers of Catalan, Galician and Spanish. The Ibero-Romance varieties under investigation are null subject languages, i.e. they allo...
Article
The present study checks the validity of the Tree-pruning hypothesis (Friedmann 1994ss, Friedmann and Grodzinsky 1997ss) to account for the experimental results of nine Ibero-Romance agrammatic subjects (4 Catalan, 2 Galician and 3 Spanish) in two controlled production tasks: completion of tense and agreement and question elicitation. According to...
Article
Problems in the production of complex structures by agrammatic subjects have been documented for many languages (Menn and Obler 1990, Friedmann 2001). To provide further evidence, the present paper aims to characterize the abnormal behavior of yes/no questions in Catalan and Galician by means of a elicited production task run with 10 mild agrammati...
Article
Full-text available
We examine the inflectional productions of seven Catalan, seven Galician, and seven Spanish speaking agrammatic subjects in an elicitation and a sentence repetition task and consider them in the light of the Tree Pruning Hypothesis (TPH). The results show relatively spared subject person/number agreement with the verb and impaired tense marking for...
Article
Nowadays more than ever, with the advance of linguistic research and its tendency to combine multidisciplinary approaches, the moment has arrived to face the structural representation of sentences as a powerful device capable to account not only for adult L1 data but also for child and impaired language. To fulfill this aim, the present paper attem...
