Lexical ambiguity resolution in non-fluent and fluent aphasia: eye-tracking data
Procedia - Social and Behavioral Sciences. 2012. Vol. 61. P. 291-292.
Inefficient lexical processing has been found in both fluent and non-fluent aphasia, although different underlying mechanisms were proposed for those two clinical populations (Prather et al., 1997). Individuals with non-fluent aphasia were suggested to have delayed initial lexical activation, while problems of individuals with fluent aphasia concerned inhibition of irrelevant activation. The current study was designed to further tap into the time course of lexical processing in non-fluent and fluent aphasia. Specifically, lexical ambiguity resolution was investigated using an eye‐tracking‐while‐listening paradigm.

Linguistic problems of individuals with agrammatic aphasia are not solely restricted to the grammatical domain: a considerable delay in lexical processing was also found in this clinical population (Prather et al., 1997). It was suggested that language processing abilities of aphasic individuals is predictable from their working memory (WM) capacities (Caspari et al., 1998; Friedmann ...

The purpose of the present study was to identify general and syndrome-specific deficits in the lexical processing of individuals with non-fluent and fluent aphasia compared to individuals without cognitive, neurological or language impairments. The time course of lexical access, as well as lexical selection and integration was studied using a visual-world paradigm in three groups ...

The present study employed the visual-world paradigm with eyetracking to discriminate between two versions of the reordered access model - namely, whether meaning frequency and context affect (a) speed of lexical access or (b) the relative weight of simultaneously accessed meanings. The time course of lexical access and meaning integration were studied in 3 groups ...

There is converging evidence that there are cognitive nonlinguistic deficits in aphasia and that these cognitive nonlinguistic deficits tend to exacerbate the language impairment of persons with aphasia. Still much remains unknown about joint impact of various cognitive mechanisms or their differential influence on language processing depending on the type of aphasia. The goal of ...

There is converging evidence that there are cognitive nonlinguistic deficits in aphasia and that these cognitive nonlinguistic deficits tend to exacerbate the language impairment of persons with aphasia. For instance, concurrent memory load or on-going interference (even when it is non-linguistic in nature) strongly affects accuracy and speed of linguistic processing in aphasia (Murray, 1999). ...

Naming actions in non-fluent aphasia: an fMRI study of compensatory reorganization of brain activity

Key characteristics of non-fluent (Broca, motor) aphasia are, among others, verb finding difficulties and effortful speech output. These characteristics are related to different levels of speech production (lexical retrieval and motor execution). This study was aimed at identifying patterns of its reorganization depending on the locus of the linguistic deficit in patients with non-fluent aphasia. ...

Working memory (WM) is essential to auditory comprehension; thus, understanding of the nature of WM is vital to research and clinical practice to support people with aphasia. A key challenge in assessing WM in people with aphasia is related to the myriad deficits prevalent in aphasia, including deficits in attention, hearing, vision, speech, and motor ...

Cross-linguistic data suggest that the grammatical categories of tense and aspect are not generally impaired in individuals with aphasia (see Bastiaanse et al., 2011 for a review). Rather, and more specifically, verb forms expressing reference to the past or conveying perfective semantics are more impaired than verb forms expressing reference to the non-past (present or future) or conveying ...

Agrammatic speakers have problems with grammatical encoding and decoding. However, not all syntactic processes are equally problematic: present-time-reference/who-questions/reflexives can be processed by narrow syntax alone and are relatively spared compared to past-time-reference /personal pronouns/which-questions that need additional access to discourse and information structures to link to their referent outside the clause (Avrutin, 2006). Linguistic processing ...

Features of focused attention in patients with fluent and non-fluent aphasia were investigated in the study. Attention disorders in patients with aphasia were quantitatively and qualitatively analyzed by making inter-comparison and comparing against the same disorders in healthy individuals. Forty seven patients with different forms of aphasia (aged 24–75) and thirty nine neurologically intact subjects ...

The article introduces the new corpus of eye-movements in silent reading – the Russian Sentence Corpus (RSC). Russian uses Cyrillic script that has not yet been investigated in cross-linguistic eye-movement research. As in every language studied so far, we have confirmed the expected effects of low-level parameters, such as word length, frequency, and predictability, on the eye-movements of skilled ...

Deficits in working memory (WM) are an important subset of cognitive processing deficits associated with aphasia. However, there are serious limitations to research on WM in aphasia largely due to the lack of an established valid measure of WM impairment for this population. The aim of the current study was to address shortcomings of previous ...

A growing literature is pointing towards the importance of white matter tracts in understanding the neural mechanisms of language processing, and determining the nature of language deficits and recovery patterns in aphasia. Measurements extracted from diffusion-weighted (DW) images provide comprehensive in-vivo measures of local microstructural properties of fiber pathways. In the current study, we compared ...

world’s commonly spoken languages. Furthermore, few aphasia tests in languages other
than English have been standardised and normed, and few have supportive psychometric
data pertaining to reliability and validity. The lack of standardised assessment tools
across many of the world’s languages poses serious challenges ...

In Russian legal texts there are many various language-based phenomena identified by lawyers as “cases of indeterminacy.” Looking at these phenomena from a linguistic point of view allows one to offer their meaningful classification. This article presents such a classification. It is based on the traditional distinction between ambiguity (we discuss only lexical, structural, and ...

Language processing has been suggested to be partially automatic, with some studies suggesting full automaticity and attention independence of at least early neural stages of language comprehension, in particular, lexical access. Existing neurophysiological evidence has demonstrated early lexically specific brain responses (enhanced activation for real words) to orthographic stimuli presented parafoveally even under the condition ...

Background
Implicit-statistical learning (ISL) research investigates whether domain-general mechanisms are recruited in the linguistic processes that require manipulation of patterned regularities (e.g. syntax). Aphasia is a language disorder caused by focal brain damage in the left fronto-temporal-parietal network. Research shows that people with aphasia (PWA) with frontal lobe lesions manifest convergent deficits in syntax and ISL mechanisms. ...
