Abstract: Cooperation, defined as the act of working together toward a shared goal, inherently involves balancing competing individual and collective interests—the core of cooperative dilemmas. Biological market theory posits that partner selection in cooperative contexts depends on three key factors: perceived capacity to provide benefits, willingness to cooperate, and accessibility. Facial cues, particularly attractiveness and trustworthiness, serve as heuristic indicators of these cooperative qualities. In the digital era, the widespread use of photo beautification tools and the increasing prevalence of online collaboration platforms have created new opportunities for curated self-presentation. This convergence raises critical questions about how photo beautification influences cooperative dynamics—a gap this study seeks to address by examining facial skin smoothing, one of the most commonly used photo-editing techniques. While moderate skin smoothing enhances perceived attractiveness and trustworthiness by creating a more polished appearance, excessive editing may paradoxically undermine these qualities by reducing perceived naturalness.

Key words: facial smoothness, cooperation, facial attractiveness, facial trustworthiness

摘要: 通过两个实验探讨面孔光滑度对合作意愿和行为的影响,并检验面孔可信度和吸引力的中介作用。实验1操纵面孔照片的磨皮水平,发现合作意愿及男性面孔的吸引力和可信度评分均随光滑度呈现倒U形变化趋势。实验2采用重复囚徒困境任务,进一步发现面孔光滑度通过可信度间接影响男性面孔合作行为,而吸引力没有显著中介作用。性别差异分析发现,女性面孔对磨皮水平变化不敏感,其合作意愿和行为未表现出显著变化。结果表明,对男性面孔的适度磨皮能通过提高面孔可信度来增加合作行为,但过度磨皮反而减少可信度与合作。研究结果揭示了面孔线索对合作的复杂作用机制,拓展了生物市场理论在合作研究中的应用。
