Investigating Attentional Allocation With Eye Tracking During Category Learning in People With Aphasia

In this study, no differences were observed between individuals with aphasia and control participants on behavioral measures of accuracy and response time, though accuracies overall were lower than those of prior studies examining this task in young adults. Eye gaze data demonstrated that over the course of training, controls and individuals with aphasia learned to reduce the number of looks to the feature of lowest diagnosticity, suggestive of optimized attentional allocation. Eye gaze patterns, however, did not show increased looking or look times to all features of highest diagnosticity, which has been seen in young adults. Older adults and individuals with aphasia may benefit from additional processing time or additional trials during category learning to optimize attention and behavioral accuracy. Findings are relevant to consider in clinical settings where visual stimuli are presented as instructional, supporting, and/or compensatory tools.

Abstract The aim of this paper is to integrate different bodies of research including brain traveling waves, brain neuromodulation, neural field modeling and post-stroke language disorders in order to explore the opportunity of implementing model-guided, cortical neuromodulation for the treatment of post-stroke aphasia. Worldwide according to WHO, strokes are the second leading cause of death and the third leading cause of disability. In ischemic stroke, there is not enough blood supply to provide enough oxygen and nutrients to parts of the brain, while in hemorrhagic stroke, there is bleeding within the enclosed ...

Wood, Dani Bryant, Kerryann Scirocco, Hia Datta, Susan Alimonti, Dave MowersAbstractAphasia, most often caused by brain damage due to stroke, is a language disorder hindering one's ability to verbally express and/or comprehend language, ranging in severity from mild to severe. An Applied Thematic Analysis (ATA) was undertaken of a post-production focus group to evaluate a 12-week pilot program that used the CoActive Therapeutic Theater (CoATT) Model for persons in Aphasia recovery. Results of a focus group interview found five th...

In conclusion, FAS is a rare motor speech disorder, often related to cerebrovascular accidents involving critical regions in the dominant hemisphere. In addition, the present case adds further evidence to the role of the left primary motor cortex in modulation of prosody. In rare cases FAS can be the only sign of stroke or can appear after recovery from post-stroke aphasia.

Gillebert, Dante Mantini, Cathy J. Price, Thomas M.H. HopeAbstractAround a third of stroke survivors suffer from acquired language disorders (aphasia), but current medicine cannot predict whether or when they might recover. Prognostic research in this area increasingly draws on datasets associating structural brain imaging data with outcome scores for ever-larger samples of stroke patients. The aim is to learn brain-behavior trends from ...

We assessed self-managed computerised speech and language therapy (CSLT) as a means of providing more therapy than ...

Conclusion For these participants with apraxia of speech plus aphasia due to stroke, satisfactory gains were made in word production accuracy with an app-based therapy program providing ASR-based feedback on accuracy. Findings support further testing of this ASR-based approach as a supplement to clinician-run sessions to assist clients with similar profiles in achieving higher amount and intensity of practice as well as empowering them to manage their own therapy program.

More than 50 years of research has demonstrated the profound effect that aphasia has on people with the condition and their family members. In the International Classification of Functioning, Disability and Health, the World Health Organization described the impact of an individual's health condition on a significant other as “third-party disability.” Recent research has described how third-party disability can occur in family members of people with aphasia post-stroke. Despite the extensive history and ongoing relevance of these findings, family-centered rehabilitation has been slow to integrate into clinical ...

CONCLUSIONS &IMPLICATIONS: This study confirms the efficacy of using smart tablets to improve naming in post-stroke aphasia. Although more studies are needed, the use of new technologies is unquestionably a promising approach to improve communication skills in people with aphasia, especially by targeting vocabulary that is relevant to them in their daily lives.
