People have multiple opportunities to act prosocial any given day but only limited resources to do so (e.g. time, effort and money they are willing to invest). We test whether people prefer to diversify their prosocial efforts across different types of help: casual help, direct help, indirect help and emotional support. In two daily diary studies (total N = 711), we examine whether previous prosocial behaviour affects subsequent prosocial behaviour for the same or other types of prosocial behaviour. We found that day-to-day prosocial behaviours reflected a diversified helping pattern. Participants were less likely to help the same way (i.e. the same type of prosocial behaviour) on subsequent days and more likely to help in different ways (i.e. a different type of prosocial behaviour). This tendency did not extend to casual help in Study 2, implying that the next day reduction in doing the same type of prosocial behaviour is limited to prosocial behaviours that are at least somewhat effortful or time consuming.

人们更喜欢多样化不同类型的亲社会行为

人们在任何一天都有多种机会表现出亲社会行为，但这样做的资源有限（例如，他们愿意投入的时间、精力和金钱）。我们测试人们是否更愿意在不同类型的帮助中分散他们的亲社会努力：临时帮助、直接帮助、间接帮助和情感支持。在两项日常日记研究中（总共N = 711），我们检查先前的亲社会行为是否会影响相同或其他类型的亲社会行为的后续亲社会行为。我们发现，日常的亲社会行为反映了多样化的帮助模式。参与者在随后的日子里不太可能以相同的方式（即相同类型的亲社会行为）提供帮助，而更有可能以不同的方式提供帮助（即不同类型的亲社会行为）。在研究 2 中，这种趋势并没有扩展到临时帮助，这意味着第二天减少做相同类型的亲社会行为仅限于至少有点费力或耗时的亲社会行为。
