Four studies investigated the differential effects of giving time vs. giving money on well-being and related mechanisms. Studies 1 and 2 used a recall paradigm, Study3 was a laboratory experiment, and Study 4 combined daily surveys with a recall procedure. Across the studies, we failed to find any substantial difference in happiness or meaningfulness associated with the two types of prosocial behaviors, which was probably due to insufficient statistical power. Yet, we found that individuals tended to recall experiences of giving time (vs. money) that were associated with higher satisfaction of the needs for relatedness and competence. Moreover, for both types of prosocial behaviors, the fulfillment of the three basic needs in SDT, autonomy, competence, and relatedness, as well as beneficence (i.e., perceived prosocial impact), all acted as important predictors of happiness and meaningfulness. Implications for research on the psychological consequences of prosocial behaviors, and the roles of basic needs and beneficence in promoting well-being are discussed.

有四项研究调查了奉献与奉献对幸福感和相关机制的不同影响。研究1和2使用召回范例，Study3是实验室实验，研究4将每日调查与召回程序结合在一起。在整个研究中，我们未能发现与两种亲社会行为相关的幸福感或意义上的实质性差异，这可能是由于统计能力不足所致。但是，我们发现，个人倾向于回想付出时间（相对于金钱）的经历，这些经历与对亲密感和能力要求的更高满意度相关。此外，对于这两种亲社会行为，满足SDT的三个基本需求，自治，能力和相关性以及受益（即感知到的亲社会影响），所有这些都是幸福和有意义的重要预测指标。讨论了对亲社会行为的心理后果，基本需求和慈善行为在促进幸福感方面的研究意义。
