成本效益分析是在各种背景下成熟决策和行为的核心。鉴于对婴儿亲社会性本质的争论，我们调查了18个月大的婴儿（N = 160）的亲社会行为是否受到预期成本和收益的影响。婴儿参与了一项帮助任务，在这项任务中，他们可以携带一个重块或轻块穿过房间，以帮助实验者。婴儿的帮助行为减弱时，预期的物理成本是高与低（实验1），和高成本的帮助下，提高了内在的动机利益的条件下（实验2和3）。高成本的帮助进一步预测了婴儿的几个月的步行经验，大概是因为携带一个沉重的块在房间里是更费力的经验较少的步行者比更有经验的步行者证明婴儿主观校准成本。因此，婴儿的亲社会反应可能是由一个理性的决策过程，权衡和整合成本和效益。
Cost-benefit analyses are central to mature decision-making and behavior across a range of contexts. Given debates regarding the nature of infants’ prosociality, we investigated whether 18-month-old infants’ (N = 160) prosocial behavior is impacted by anticipated costs and benefits. Infants participated in a helping task in which they could carry either a heavy or light block across a room to help an experimenter. Infants’ helping behavior was attenuated when the anticipated physical costs were high versus low (Experiment 1), and high-cost helping was enhanced under conditions of increased intrinsic motivational benefits (Experiments 2 and 3). High-cost helping was further predicted by infants’ months of walking experience, presumably because carrying a heavy block across a room is more effortful for less experienced walkers than for more experienced walkers demonstrating that infants subjectively calibrate costs. Thus, infants’ prosocial responding may be guided by a rational decision-making process that weighs and integrates costs and benefits.
