Abstract Images are commonly used in environmental advocacy campaigns that are designed to promote collective action. However, the effects of different types of images have rarely been examined. In three experiments (combined N = 1426), we tested the impact of commonly used campaign images (meeting, protest, or no image) on willingness to engage in collective action against coal mining. Further, we examined whether images influence known drivers of collective action. Results support the Social Identity Model of Collective Action in environmental contexts: efficacy, identification and anger were strongly associated with collective action intentions and (less so) behaviour. Identification was the strongest predictor of actual behaviour. The effects of images were inconsistent. Image presence and type sometimes affected collective action responses, either directly or indirectly. The presence of an image sometimes increased perceptions of descriptive norms for action, which in turn increased perceived efficacy and collective action intentions.

测试图像在环保运动中的影响

摘要图像通常用于旨在促进集体行动的环境宣传活动。然而，很少研究不同类型图像的影响。在三个实验中（组合 N = 1426），我们测试了常用的运动图像（会议、抗议或无图像）对参与反对煤矿开采的集体行动的意愿的影响。此外，我们检查了图像是否影响已知的集体行动驱动因素。结果支持环境背景下集体行动的社会认同模型：效能、认同感和愤怒与集体行动意图和（较少）行为密切相关。认同是实际行为的最强预测因素。图像的效果不一致。图像的存在和类型有时会影响集体行动的反应，直接或间接。图像的存在有时会增加对行动的描述性规范的感知，这反过来又增加了感知效率和集体行动意图。
