With the increase in globalized threats that can span across continents, there is a greater need for people to come together to overcome difficulties to help one another. Given that certain positive emotions have been suggested as a functional social binding agent to organize cohesive help in bad times (Stellar et al., 2017), we propose that feeling moved is one such positive emotion that benefits the individual by alleviating one’s personal difficulties during threatening circumstances, and hence build up mental resources to help the individual and possibly others. In a cross-cultural study (168 Japan and 146 US participants), we compared nature-related threatening situations with varying impact (hurricane in one’s home country versus globally) and examined if they enhanced the feeling of being moved, labelled as Kama Muta (KAMMUS Two: Zickfeld et al., 2019) and if it alleviated their negative attitudes towards personal problems. Participants’ competency to help others, and actual prosocial behavior, in the form of monetary donations, were also measured. Path analysis revealed that the nature threat condition enhanced Kama Muta through perceived societal impact, and the subsequent alleviation of negative attitudes towards personal problems increases participants’ help competence. Additional analyzes also showed that Kama Muta functioned similarity in both cultures, suggesting that its function may be rudimentary for survival during threatening contexts (Cullhed, 2020). Implications on the adaptiveness of positive emotional responses in bad times and applications for cohesive responses during natural disasters will be discussed.
