MRMengmeng RENJLJin LIYZYiping ZHONG

Key Points

  • This research examines how different types of social norms affect pro-environmental behavior and the role of moral identity.
  • Conducted better goods game tasks.
  • Utilized functional near-infrared spectroscopy (fNIRS) for neural analysis.
  • Analyzed the moderating effect of moral identity on social norms and behavior.
  • Moral identity activation significantly increased pro-environmental behavior influenced by injunctive norms.
  • Descriptive norms showed a higher tendency towards pro-environmental behavior compared to injunctive norms under non-activated conditions.
  • Neural activation patterns highlighted specific brain regions involved in moral identity and norm types.

Abstract

摘要: 在生态环境问题日益严峻的背景下, 促进个体亲环境行为至关重要。社会规范虽为关键外部因素, 但不同类型效力存在差异, 其中指令性规范的效力弱于描述性规范, 其心理与神经机制尚不明确。本研究采用更好物品博弈任务并结合fNIRS技术, 考察道德认同在不同社会规范类型影响亲环境行为中的调节作用及其神经机制。结果表明, 道德认同启动条件下, 指令性规范较描述性规范显著提升亲环境行为及其倾向; 未启动条件下, 描述性规范较指令性规范, 行为选择未达到显著, 但呈现更高亲环境倾向。神经结果显示, 道德认同伴随背外侧前额叶皮层激活增强。进一步分析发现, 指令性规范与道德认同主要激活眶额叶皮层与内侧前额叶皮层; 描述性规范与道德认同主要激活右侧颞顶联合区。研究揭示社会规范影响亲环境行为的双路径机制, 并表明道德认同具有关键调节作用。研究为政策与实践提供启示,通过激活道德认同增强指令性规范的引导力, 并结合描述性规范的稳定效应, 为基于神经机制的行为干预提供实证依据。
