Fostering Prosocial Preventive Behaviours Through Awe

The goal of this randomized control trial is to investigate the impact pf awe on prosocial preventive behaviours against infectious diseases among adults from Hong Kong, Singapore, and ten major cities in Mainland China (Beijing, Shanghai, Guangzhou, Shenzhen, Hangzhou, Chongqing, Chengdu, Wuhan, Xi'an, Nanjing). The main questions it aims to answer are: * Does experiencing awe increase adults' intentions to engage in prosocial preventive behaviours against infectious diseases, including vaccination, mask wearing, and social distancing? * Does the impact vary across three research sites?
