Effect of speech-related smile suppression on emotional valence
Bibliographic record
Abstract
The physical act of smiling has direct positive effects on mood [Kleinke et al., Pers. Soc. Psychol. 74, 272–279 (1998)]. Relatedly, Rummer et al. [Emotion, 14(2), 246–250 (2014)] observed that participants rated comics as funnier if they had just produced /i/ (which requires adopting a smile-like position) than if they produced /o/. The present study tests whether suppression of smile posture by speech movements can cause individuals to view a subject less positively. To do so, we ask participants to maintain a smile while we present a series of visual stimuli labeled with target and control sounds. Bilabial sounds are targeted as Liu et al. found that bilabial stops (/p/ and /b/) suppress smile posture [ISSP12, 130–133 (2021)]. After articulating a sound that either suppresses or does not suppress their smile posture, participants rate each image set on a measure of emotion. Results will be presented and discussed bearing on the prediction that in the smile condition, participants will rate the image as less positive if they have just produced a sentence which includes a bilabial stop.

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.
