Graphs Built From Reported Results

Concise synthesis (visual first):

• Context and contrast matter: isolated (low-clutter) presentation boosts perceived aesthetic value and liking for visual objects in controlled experiments — an effect strongest for items with lower intrinsic aesthetic quality and for viewers with less art knowledge Clutter x aesthetics moderation.
• Facial geometry influences both harmony and youthfulness judgments, but different angles favor different percepts (what looks most "harmonious" is not always judged "youngest"); cultural and 3D-perception limits apply Angle G tradeoffs.

Practical takeaways (evidence-weighted)

1. Design placement: use "white space" (low-clutter) to increase immediate aesthetic impact for objects with modest intrinsic aesthetics; effect diminishes for high-intrinsic-aesthetic items (evidence: controlled experiments) Design placement evidence.
2. Cosmetic/aesthetic interventions: altering single facial angles can trade harmony vs youthfulness; decisions should consider target percept (harmonize vs rejuvenate) and population-specific norms; 3D measurement and diverse samples are necessary before generalization Clinical aesthetics caution.

Limitations & blindspots (epistemic humility)

• Samples and stimuli are narrow: MTurk viewers and single-ethnic facial images limit external validity (generalizability) — further work needs broader populations and real-world ecological settings MTurk sampling limitation Facial study limitations.
• Mechanisms: perceived aesthetic value mediates context effects for billboards, but downstream behaviors (purchase, long-term memory) were not measured; for faces, perception is multidimensional and likely culture-dependent.

If you want to go deeper

I can: (A) plot additional condition means and moderation surfaces from the billboard paper, (B) build a perceptual trade-off visualization combining harmony vs youthfulness across continuous angle values if you want to supply morph data, or (C) combine these aesthetics results with biodiversity aesthetics (plant-diversity work) to map common perceptual rules. Tell me which and I'll generate more graphs.
