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 ...

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 ...

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 ...

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). ...

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 ...

Background: There are a limited number of aphasia language tests in the majority of the
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 the current study we present interim results of verb use analysis in two aphasic groups
based on Russian CliPS (Clinical Pear Stories) data. Russian CliPS is a multimedia corpus of
narratives produced by speakers with aphasia and right hemisphere damage, as well as
neurologically healthy speakers of Russian. ...

The paper looks at the role of working memory in the effect of “misses in continued search”. The effect consists in missing thesecond target stimulus after a successful detection of the first in a visual search task. One of the theories links the effect to the fact that the detected first stimulus exhausts the resource ...

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. ...

The article investigated the role of spatial working memory in visual search for multiple targets, in particular, in subsequent search misses effect. This phenomenon is the second target omission after the first target has been found in visual search task. One of the theoretical interpretations of subsequent search misses is the lack of resources (attention ...

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 ...

We utilized the event-related potential (ERP) technique to study neural activity associated with different levels of working memory (WM) load during simultaneous interpretation (SI) of continuous prose. The amplitude of N1 and P1 components elicited by task-irrelevant tone probes was significantly modulated as a function of WM load but not the direction of interpretation. Furthermore, ...

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 ...

Previous research has found that verb argument structure characteristics (such as the number of participant roles in the situation described by the verb) can facilitate or hinder aphasic language production and comprehension in constrained laboratory tasks. This research needs to be complemented by studies of narrative or unrestricted speech, which can capture the spontaneous selection ...

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 ...

This article reviews the research in visual working memory (VWM) over the past 20 years. We describe research methodologies in the field and focus on commonly used paradigms such as change detection and continuous report (including the use of mixed models for analysis) that aim to measure the capacity and precision of VWM. We also ...

Background: Agrammatic speakers have problems with grammatical encoding and decoding. However, not all syntactic processes are equally problematic: present time reference, who questions, and reflexives can be processed by narrow syntax alone and are relatively spared compared to past time reference, which questions, and personal pronouns, respectively. The latter need additional access to discourse and ...

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 ...

Background: Overall, there is growing consensus that working memory (WM) should be routinely assessed in individuals with aphasia as it can contribute significantly to their level of language impairment and be an important factor in treatment planning.

Background: A verb’s instrumentality and name relation to an associated instrument noun are among the factors influencing verb retrieval in speakers with aphasia. Previous data on the effects of these factors are equivocal, possibly due to language- and taskspecific factors. Aims: The present study aimed to investigate the nature of the instrumentality and verbnoun name ...
