Level of abstinence mediates heart-rate response to cue-elicited craving in smokers
Bibliographic record
Abstract

 
 
 
 The subjective and autonomic components of nicotine craving were examined in abstinent and non-abstinent smokers using a cue reactivity paradigm. A cigarette abstinent condition was used to examine how smoking deprivation mediates the activity of positive and negative reinforcement mechanisms. Levels of craving and physiologic responses were monitored during the presentation of videotaped neutral and smoking stimuli. Relative to the neutral material, smoking stimuli increased several indices of subjective craving in both abstinent and non-abstinent smokers. Autonomic responses to the smoking stimuli however, appeared to be mediated by the level of abstinence. Non-deprived smokers showed an increase in heart rate during the first minute of the smoking stimuli presentation relative to the first minute of the control video, while abstinent smokers showed no change. The autonomic responses of cigarette craving may be dependent on the perceived reinforcing value of cigarettes, which can be modulated by cigarette abstinence. These findings are consistent with the hypothesis that increased heart rate may be a marker for incentive motivation, but also strongly support a multi-dimensional model of nicotine craving. Furthermore, they stress the importance of recognising the condition of the smoker as a critical determinant in craving responses.

How this classification was reachedexpand
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.
