摘要
具身认知的大量研究发现物理冷暖能够引发个体的人际"冷暖"行为。然而,不同色温的光照环境也会使人产生不同的心理感受,如暖色系黄光使人感到温暖而放松,冷色系的蓝光让人感觉冰冷而警醒。那么暖色光是否也会让人产生心理暖而表现出更加积极的社交行为呢?本研究设置三个实验来系统考察高色温的冷白光(6500k,500lx)和低色温的暖白光(3000k,500lx)的实验室光照环境对个体亲社会行为的影响。实验1采用Williams等(2008)研究范式考察高、低色温光环境对被试印象形成的影响;实验2借鉴Lei Wang(2015)等的实验任务考察高、低色温光环境对被试人际行为的影响;实验3采用独裁者博弈任务范式考察高、低色温光环境对被试利他行为的影响。结果发现,相对于高色温的冷白光环境,低色温的暖白光照射下被试对他人的总体评价更加积极,人际维度评分显著更高;社交过程中表现出更高的容忍度及对负性生活事件的抱怨更少。在博弈任务中表现出更多的利他行为。事后测验发现,暖色光照条件组被试在情绪量表(PANAS)正性情绪维度上的评分显著高于高色温光照组,且被试自我评价心理暖的程度更高。由此表明,不同色温的冷暖光环境会引发被试产生不同的心理感受和情绪体验,在一定程度上能够影响其自身的亲社会行为。
The present studies conduct three experiments aims to examine effects of exposure to cold white light(6500k,500lx) and warm white light(3000k,500lx) on individual pro-social performances. Study 1 explored the influence of exposure to warm and cold light on impression forming and found that the participants in warm light environment were more likely to give higher evaluation to fictitious collaborator than that in cold condition. Study 2 investigated the warm light effects on interpersonal behavior.Results indicated that participants experiencing warm light were more willing to forgive a peer's dishonest behavior and were less complaint to poor social services. Studies 3 examined effects of warm light on participants' altruistic behavior. Results showed that participant exposed to warm white light would like give more fair distributions compared them exposure to cool light. In conclusions, the ambient warm light would also promote human psychological warmth and improve their own pro-social performances.
