In aphasia, damage to brain regions responsible for language processing disrupts access words previously learned and consolidated in the mental lexicon, causing people with aphasia (PWA) experience word finding difficulties that negatively impact their everyday communication. This study seeks investigate effects of a psycholinguistic training based on phonology semantics sentence production aphasic child cerebral palsy. The used single-subject multiple- baseline research design across behaviors.

Neurobehavioral studies have provided evidence for the effectiveness of anodal tDCS on language production, by stimulation left Inferior Frontal Gyrus (IFG) or Temporo-Parietal Junction (TPJ). However, is currently not used in clinical practice outside trials, because behavioral effects been inconsistent and underlying neural unclear. Here, we propose to elucidate correlates verb noun learning determine if they can be modulated with high-definition (HD) stimulation. Thirty-six neurotypical participants were randomly allocated HD-tDCS over either IFG, TPJ, sham On day one, performed a naming task (pre-test). two, underwent new-word rare nouns verbs concurrently 20 min. The third consisted post-test performance. EEG was recorded at rest during each day.

Exploring the clinical diagnostic value of linguistic learning ability in patients with disorders of consciousness using electrooculography

NeuroImage, Journal Year: 2024, Volume and Issue: 297, P. 120753 - 120753

Published: July 24, 2024

For patients with disorders of consciousness (DoC), accurate assessment residual levels and cognitive abilities is critical for developing appropriate rehabilitation interventions. In this study, we investigated the potential electrooculography (EOG) in assessing language processing levels. Patients' EOG data related electrophysiological were analysed before after explicit learning. The results showed distinct differences vocabulary learning patterns among varying consciousness. While minimally conscious significant neural tracking artificial words notable effects similar to those observed healthy controls, whereas unresponsive wakefulness syndrome did not show such effects. Correlation analysis further indicated that detected comparable validity electroencephalography, reinforcing credibility indicator as a diagnostic tool. Critically, also revealed correlations between individual patients' linguistic performance their Oromotor/verbal function assessed through behavioural scales. conclusion, study explored By demonstrating utility evaluating detecting effects, well its guide personalised rehabilitation, our findings indicate indicators promise rapid, effective additional tool diagnosing managing DoC.

Errorless and errorful learning in people with aphasia across novel-object pairing and word retrieval tasks

Aphasiology, Journal Year: 2024, Volume and Issue: unknown, P. 1 - 33

Published: Nov. 27, 2024

Background While linguistic deficits are key to diagnosing and treating aphasia, there is growing interest in the cognitive processes important for rehabilitation outcomes, particularly role of learning. Of relevance current study, research has manipulated instructional methods (errorless vs. errorful) assess their effects on outcomes. However, it still unclear whether individualized profiles errorless errorful learning exist aphasia they might be meaningful clinical practice.

Preservation of long-term memory in older adults using a spaced learning paradigm

European Journal of Ageing, Journal Year: 2023, Volume and Issue: 20(1)

Published: Feb. 1, 2023

How much information we retain depends on type/schedule of training. It has been widely acknowledged that spaced learning is advantageous compared to massed for cognitively healthy young adults and should be considered an educational standard. Literature would suggest the spacing effect preserved with age, though it unclear whether this translates more ecologically valid concepts such as face-name associations, which are particularly susceptible deterioration age. Two experiments were conducted investigate effects across recent/remote retention intervals, age in older using Face-Name Pairs task. Experiment 1 results beneficial memory observed long-term memory. 2 impaired at younger adults, influences both longer spaced-trained participants display similar forgetting patterns irrespective These may have some implications regarding improving conditions under optimum occurs (namely, when intervals outside laboratory settings), provide insight into our ability learn remember associations.

Thirty-four adults chronic, post-stroke aphasia participated Aphasia Language Impairment Functioning Therapy (Aphasia LIFT) programme, comprised of 48 h comprehensive therapy. Sets 30 treated untreated items identified at baseline were probed during impairment which targeted word retrieval using a combined semantic feature analysis phonological component approach. Multiple regression models computed to determine language demographic variables, (measured after 3 therapy) treatment outcomes. Early emerged as strongest predictor gains post-therapy 1-month follow-up.

Expressive recall and recognition as complementary measures to assess novel word learning ability in aphasia

Novel word learning ability has been associated with language treatment outcomes in people aphasia (PWA), and its assessment could inform prognosis rehabilitation. We used a brief experimental task to examine novel PWA, determine the value of phonological cueing assessing outcomes, identify factors that modulate ability. Twelve PWA nineteen healthy controls completed task, recall recognition tests Most showed comparable those controls. Learning assessed via expressive was more clearly evidenced cues. Better single processing abilities short-term memory higher integrity left inferior frontal gyrus were related better performance. Brief tasks like this one are clinically feasible hold promise as screening tools verbal once validated evaluated for their capacity predict outcomes.
