Much is known about young children's helping behavior, but little is known about the underlying motivations and emotions involved. In 2 studies we found that 2-year-old children showed positive emotions of similar magnitude-as measured by changes in their postural elevation using depth sensor imaging technology-after they achieved a goal for themselves and after they helped another person achieve her goal. Conversely, children's posture decreased in elevation when their actions did not result in a positive outcome. These results suggest that for young children, working for themselves and helping others are similarly rewarding. (PsycINFO Database Record
我们对幼儿的帮助行为了解很多，但对其中潜在的动机和情感却知之甚少。在两项研究中，我们发现，通过深度传感器成像技术测量姿势提升的变化来衡量，两岁的孩子在为自己实现目标后以及在帮助他人实现目标后，表现出了相似程度的积极情绪。相反，当孩子们的行为没有产生积极结果时，他们的姿势提升会下降。这些结果表明，对幼儿来说，为自己做事和帮助他人同样有回报。（PsycINFO数据库记录）
