Cognitive and motor dynamics of speech processing during walking
Bibliographic record
Abstract
Walking, traditionally considered an automated process, can become cognitively demanding during dual-task (DT). Up to now, language-motor interactions, such as walking and listening to speech remain underexplored in DT studies, despite the frequent co-occurrence of these activities in daily life. In addition, research on embodied semantics points at the potential of certain words’ meaning interacting with actual body movements. Yet no study so far has addressed this issue in relation to gait. This ongoing experiment examines a) the potential motor-cognitive interference of concurrent walking and speech processing and b) the potential semantic effects when action verbs are actively processed during walking. We tested 20 adults using motion capture with concurrent optical imaging (fNIRS) to assess gait variation along with frontal and motor cortex activation. Preliminary findings suggest that gait patterns remain consistent with and without speech processing during walking. However, processing action-related verbs while walking is associated with reduced motor cortex activation.

Full frame distilled prediction
Teacher imitationNot 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.
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; both teacher heads agree on what is shown here.
