Bibliographic record
Abstract
Resumo Pacientes com lesao cerebrovascular de hemisferio direito (LHD) tendem a apresentar deficits comunicativos. Este estudo visou a investigar o processamento comunicativo de pacientes com acidente vascular cerebral (AVC) de hemisferio direito. A amostra incluiu 100 participantes: 25 com LHD, 25 com AVC de hemisferio esquerdo (LHE) e 50 controles neurologicamente preservados (PNP). Os participantes responderam a um questionario de dados sociodemograficos, ao Mini Exame do Estado Mental para avaliar capacidade cognitiva geral, a Escala de Depressao Geriatrica de 15 pontos e a Escala Beck de Depressao para investigar sintomas depressivos, ao Teste dos Sinos para avaliar heminegligencia, e a Escala Rankin Modificada para verificar capacidade funcional. O processamento comunicativo foi avaliado com a Bateria Montreal de Avaliacao da Comunicacao, versao abreviada – Bateria MAC Breve. Os escores foram comparados por one-Way ANOVA e Qui-quadrado. Houve diferencas significativas entre os grupos LHD e PNP em 89% das tarefas, mas nao entre os grupos LHD e LHE. Alem disso, o grupo LHD apresentou desempenho comunicativo inferior ao grupo PNP. Tais achados sugerem evidencias de cooperacao interhemisferica para os processamentos comunicativos. Resumen Los pacientes con lesion cerebrovascular de hemisferio derecho (LHD) tienden a presentar deficits comunicativos. Este estudio tuvo como objetivo investigar el procesamiento comunicativo de pacientes con accidente cerebrovascular (ACV) de hemisferio derecho. La muestra incluyo 100 participantes: 25 con LHD, 25 con ACV de hemisferio izquierdo (LHI) y 50 controles neurologicamente preservados (CNP). Los participantes respondieron a un cuestionario sociodemografico, el Mini Examen del Estado Mental para medir la capacidad cognitiva general; la Escala de Depresion Geriatrica y la Escala Beck de Depresion, para investigar los sintomas depresivos; el Test de Marcacion de Campanas, para evaluar heminegligencia, y la Escala de Rankin Modificada, para verificar la capacidad funcional. El procesamiento comunicativo fue evaluado con la Bateria Montreal de Evaluacion de la Comunicacion, version abreviada – Bateria MAC Abreviada. Las puntuaciones fueron comparadas por ANOVA de una via y Chi-cuadrado. Hubo diferencias significativas entre los grupos LHD y CNP en 89% de las tareas, pero no entre los grupos LHD y LHI. Ademas, el grupo LHD presento un desempeno comunicativo inferior al grupo CNP. Tales descubrimientos sugieren evidencias de cooperacion interhemisferica para los procesamientos comunicativos. Abstract Patients with right hemisphere brain damage (RBD) usually experience communication impairments. This study aims to investigate the communication processing in patients who suffered a stroke in the right hemisphere. The sample comprised 100 participants: 25 with RBD, 25 with left hemisphere brain damage (LBD) and 50 neurologically healthy controls (NHC). Participants answered a sociodemographic questionnaire, the Mini Mental State Examination to measure general cognitive ability, the Geriatric Depression Scale and the Beck Depression Scale to investigate depressive symptoms, the Bells Test to evaluate hemineglect and the Modified Ranking Scale to verify functional capacity. The communication processing was assessed with the use of the Montreal Communication Evaluation Battery, brief version – Brief MAC Battery. The scores were compared using a One-Way ANOVA and the Chi-squared test. There were significant differences between RBD and NHC groups in 89% of the tasks, but not between RBD and LBD groups. Furthermore, the RBD showed inferior communication skills compared to the NHC group. These findings indicate an interhemispheric cooperation for communication processing.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
