Planning keypress and reaching responses: Effects of response location and number of potential effectors.
Bibliographic record
Abstract
In previous work the authors argued that the potential number of effectors in the response set is crucial in discriminating (multiple-effector) keypress from (single-effector) reaching responses. It is not clear, however, what influence the locus of responding (on vs. off the stimulus location for reaching and keypressing, respectively) has on reaction time (RT) performance. In 3 experiments, the authors systematically manipulated response location and response type using a spatial precuing task. The results consistently showed that even though response location did influence the RTs of keypress and reaching responses, the effect of the number of potential effectors was dominant in shaping the prototypical RT profiles of the 2 response types. These outcomes underscore the importance of the anatomical identity, in addition to response location, in response coding and corroborate the notion that distinct mechanisms dominate performance in single- and multiple-effector visuomotor tasks.

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; a candidate call from one teacher head, not a consensus.
