Abstract
Abstract This experiment examined the effects of commercial exercise video models on women's self-presentational efficacy (SPE) and exercise task self-efficacy (EXSE). Participants were 101 women (M age = 20.1, SD = 1.14) who completed baseline measures of exercise status, SPE, and EXSE. One week later, they watched an exercise video featuring either "perfect-looking" exercisers whose bodies epitomized the ultra-thin, ultra-toned female cultural body ideal, or a video in which the exercisers were considered more "normal-looking." Post-video, the SPE and EXSE measures were readministered along with a measure of exercise intentions. Controlling for baseline measures of self-efficacy, a series of 2 (model condition: perfect-looking vs. normal-looking) × 2 (participant's exercise status: regular exerciser vs. infrequent/nonexerciser) ANCOVAs indicated women who saw the perfect-looking models had lower post-test SPE regardless of their exercise status (p < .05) and that nonexercisers had lower post-test SPE after watching either type of model (p < .05). There were no effects of model type on EXSE. SPE also explained significant variance in exercise intentions (ΔR2 = .06) beyond that explained by EXSE (ΔR2 = .39). Results are discussed in terms of theoretical and practical significance.

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 it
