Abstract
The purpose of the current study was to examine the relationship between movement preparation and excitability of subcortical motor circuits, as measured by the reflexive response to a startling acoustic stimulus. We compared the size and incidence of activation in the sternocleidomastoid (startle indicator) from participants completing either a simple or choice reaction time (RT) task. Consistent with predictions, results indicated that the startle reflex habituated after several presentations of the SAS for the choice RT group but not for the simple RT group, which we attributed to advance motor preparatory processes involved in a simple RT task. Additionally, when participants from the choice RT group were put into a simple RT condition, the startle reflex response returned to nonhabituated levels. We conclude that the increased corticospinal activation associated with advance preparation may also result in increased subcortical activation, accounting for the observed lack of habituation to a startling stimulus in simple RT.

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 it
