Abstract

fetched live from OpenAlex

Cognitive deficits can be present in people with aphasia and may affect their language abilities. Neuroimaging research suggests a correlation between the activation of brain regions responsible for executive functions and language recovery in aphasia. Considering the critical role of executive functions in language rehabilitation and the inconsistencies reported in previous findings, the present study aimed to characterize the executive function profiles of individuals with Broca's aphasia. Thirty individuals with Broca's aphasia and 30 healthy controls were examined using the Western Aphasia Battery (WAB) and the Delis-Kaplan Executive Function System (D-KEFS). D-KEFS subtests, including Trail Making, Design Fluency, Sorting, Tower, and Proverb, were used were used to assess problem-solving, creativity, inhibition, concept formation, cognitive shifting, spatial planning, rule learning, and cognitive set maintenance. Individuals with Broca's aphasia performed significantly lower than healthy controls on all tests, demonstrating greater difficulty in specific executive function domains. These results indicate a strong correlation between Broca's aphasia and executive functions.

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
