Abstract
Although landfills are being converted into green spaces, little is known about how such areas affect mood, cognition, and physiology. Using a within-subject experimental design (n = 31 men), we found that walking through a naturalized landfill improved mood more than did walking through an adjacent urban area. Both walks improved energy and attentional control and decreased concentrations of cortisol (a marker of stress). One's sense of connectedness with nature moderated the effects of the walks on mood: For men reporting high nature connectedness, mood improved after both walks. For men reporting low nature connectedness, positive mood increased after the naturalized landfill walk and decreased after the urban walk. Follow-up analyses indicated that differential perceptual attentiveness to subtle natural or green features may explain this moderation. Thus, naturalized landfills may enhance the benefits of walking on mood, and nature connectedness may buffer against the harmful effects of urbanization. Key Words: Nature—Restoration—Green space—Mood—Well-being—Brownfields.

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
