In recent years, correlational evidence has accumulated in support of a positive relationship between positive affect and pro-environmental behavior. In contrast, it remains unclear whether the induction of positive affect can causally promote pro-environmental behavior. Previous attempts to examine the effects of experimental affect induction were constrained by the difficulty to study pro-environmental behavior under controlled laboratory conditions. Here, we address this limitation by examining the effect of a validated affect-induction procedure on a recently validated laboratory measure of pro-environmental behavior. Participants in our preregistered experiment (N = 178) watched and rated video clips pretested to induce either positive or neutral affect before completing 24 trials on the Pro-Environmental Behavior Task (PEBT). Results did not reveal any evidence in support of a positive effect of positive affect on PEBT behavior. This result illustrates the need for further systematic and cumulative research on the complex relationship between affect and pro-environmental behavior.

近年来，已经积累了相关证据来支持积极影响与亲环境行为之间的积极关系。相反，尚不清楚诱导积极影响是否能因果促进环保行为。以前研究实验性影响诱导作用的尝试受到了在受控实验室条件下难以研究前环境行为的限制。在这里，我们通过检查经过验证的情感诱导程序对最近经过验证的亲环境行为实验室措施的影响来解决此限制。参加我们预先注册的实验（N = 178）观看和分级的视频剪辑，在完成针对“亲环境行为任务（PEBT）”的24个试验之前，进行了正向或中性的测试。结果没有显示任何证据支持对PEBT行为产生积极影响的积极作用。该结果说明了需要对影响与亲环境行为之间的复杂关系进行进一步的系统性和累积性研究。
