“…This section of our review is about the nature of bilingual language control in PWA. If bilingual language control impairments are consistently paired with EC impairments, this may have implications for recovery because the integrity of EC is crucial for aphasia recovery and treatment (Olsson et al, 2019; Simic, Bitan, Turner, Chambers, Goldberg, Leonard & Rochon, 2020). Similarly, if language control relies on domain-general EC, training of the latter could lead to improvements in language (Kiran & Gray, 2018).…”

Executive control in bilingual aphasia: a systematic review

et al. 2021

Much research has been dedicated to the effects of bilingualism on executive control (EC). For bilinguals with aphasia, the interplay with EC is complex. In this systematic review, we synthesize research on this topic and provide an overview of the current state of the field. First, we examine the evidence for EC deficits in bilingual persons with aphasia (bPWA). We then discuss the domain generality of bilingual language control impairments. Finally, we evaluate the bilingual advantage hypothesis in bPWA. We conclude that (1) EC impairments in bPWA are frequently observed, (2) experimental results on the relationship between linguistic and domain-general control are mixed, (3) bPWA with language control problems in everyday communication have domain-general EC problems, and (4) there are indications for EC advantages in bPWA. We end with directions for experimental work that could provide better insight into the intricate relationship between EC and bilingual aphasia.

“…Other executive functioning skills, such as reasoning (e.g., RPM) and inhibition (e.g., Stop Signal Task), similarly lacked a significant relationship with treatment outcomes in most studies included in this review. That said, the studies employing RPM or RCPM (Rose et al, 2013; Seniów et al, 2009) lacked a clear analysis of effects on treatment maintenance and one (Simic et al, 2020) of the two studies examining the relationship between inhibition and maintenance reported a positive result. Therefore, future studies should continue to investigate the potential impact of reasoning and inhibition on delayed follow-up assessment, as well as further explore evidence of their impact on generalization (Kendall et al, 2014; Sandberg et al, 2021).…”

“…Executive functions, such as initiation, planning, self-monitoring, and cognitive flexibility, have been reported as impaired in persons with aphasia (Murray, 2017). Additional studies have further reported that executive control is independent of an individual's language disorder, leading to conclusions that executive functioning itself may lead to varied treatment outcomes (Brownsett et al, 2014; Simic et al, 2020).…”

The purpose of this article was to explore the extent to which nonlinguistic cognitive factors demonstrate a relationship with aphasia treatment outcomes. To that end, we conducted a scoping review to broadly characterize the state of the literature related to this topic. Methods: Reporting guidelines from the PRISMA extension for scoping reviews were used to conduct our study, which queried two common databases used in the health science literature, PubMed and Web of Science. Search terms and eligibility criteria are provided. Results are organized by the four nonlinguistic domains of cognition explored across the included studies (i.e., attention, memory, executive functioning, and visuospatial skills). Results: Of 949 unique articles identified from our database searches, 17 articles with 18 distinct studies were included in the final scoping review. Notably, most studies included in the scoping review targeted impairment-based aphasia treatments. Most studies also examined multiple domains of nonlinguistic cognition. A relationship between cognition and poststroke aphasia therapy outcomes was identified in nine of 15 studies addressing executive functioning, four of nine studies examining memory, four of eight studies examining visuospatial skills, and two of five studies exploring attention. Discussion: The results among included studies were mixed, with few discernible patterns within each of the four cognitive domains, though it appears that the influence of nonlinguistic cognition may depend on the timing (i.e., immediate vs. delayed post-treatment) and type (i.e., trained vs. untrained, generalized) of aphasia therapy outcomes. Future study designs should address maintenance, by including outcome measures at follow-up, and generalization, by including measures of performance on either untrained stimuli or trained stimuli in untrained contexts. Future work should also strive for larger sample sizes, perhaps through collaborations, or prioritize replicability to produce more reliable conclusions.

“…Apart from clinical reasons [70], knowing about sentence recall abilities in people with milder forms of aphasia could help us to understand the relationship of STM and LTM in these individuals. The interactive relationship of these constructs has been debated for decades in mainstream cognitive psychology [56][57][58]71] as well as aphasiology [36,72,73].…”

Sentence Recall in Latent and Anomic Aphasia: An Exploratory Study of Semantics and Syntax

2021

View full text Add to dashboard Cite

We investigated whether semantic plausibility and syntactic complexity affect immediate sentence recall in people with latent and anomic aphasia. To date, these factors have not been explored in these types of aphasia. As with previous studies of sentence recall, we measured accuracy of verbatim recall and uniquely real-time speech measures. The results showed that accuracy did not distinguish performance between latent aphasia and neurotypical controls. However, some of the real-time speech measures distinguished performance between people with latent aphasia and neurotypical controls. There was some evidence, though not pervasive, that semantic plausibility and syntactic complexity influenced recall performance. There were no interactions between semantic plausibility and syntactic complexity. The speed of preparation of responses was slower in latent aphasia than controls; it was also slower in anomic aphasia than both latent and control groups. It appears that processing speed as indexed by temporal speech measures may be differentially compromised in latent and anomic aphasia. However, semantic plausibility and syntactic complexity did not show clear patterns of performance among the groups. Notwithstanding the absence of interactions, we advance an explanation based on conceptual short-term memory as to why semantically implausible sentences are typically more erroneous and possibly also slower in recall.
