The effects of experimenter status and cardiovascular reactivity on pain reports
Bibliographic record
Abstract
Existing evidence suggests that experimenter characteristics can influence research participants' pain reports. To examine the possibility that cardiovascular reactivity may serve as a potential mediating mechanism, blood pressure responses to stress were recorded in 117 healthy women during an arithmetic task and a subsequent cold pressor pain task. Laboratory sessions were conducted by two experimenters (i.e., a university professor and a graduate research assistant), who differed significantly on participant ratings of perceived social status. Participants tested by the university professor showed greater blood pressure responsivity to arithmetic and had higher pain tolerance and lower pain unpleasantness ratings compared to those tested by the research assistant. Further, hierarchical regression analyses indicated that blood pressure reactivity was a potential mediator of the association between experimenter status and both pain tolerance and unpleasantness, suggesting that perceived experimenter status may elicit physiological adaptations that can reduce sensitivity to painful laboratory stimuli.

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.
