Stopped cold: Motor-response inhibition reduces the capacity of sexually-explicit stimuli to elicit subjective and physiological sexual arousal
Bibliographic record
Abstract
The motivational incentive of sexual stimuli can be a salient force in determining the focus of thought and behaviour. Here we show that the simple act of not pressing a key during the perception of sexual content reduces its motivational incentive and subsequent capacity to elicit sexual arousal. Undergraduate participants (N=116) completed a Go/No-go task that required them to inhibit responses to either sexual or non-sexual images. Later they watched sexually explicit videos and reported moment-to-moment changes in self-reported sexual arousal, while thermography was used to record changes in genital physiological arousal. Participants who previously inhibited sexual images experienced lower levels of both self-reported and physiological arousal than those who inhibited non-sexual images. These results extend prior research to suggest that a by-product of motor-response inhibition is a negative alteration of stimulus-value representations for associated items— the kind of value that drives even the most biologically-fundamental forms of motivated behaviour.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
