This study aimed to assess social preferences in dynamic interpersonal interactions among preschool children and to examine the effects of peer relationship (friend vs. stranger) and peer presence (peer presence vs. peer absence) on giving and repaying. Ninety‐nine children participated in a triad game, which consisted of two mixed‐dictator games. The allocations from a proposer in the first dictator game were evaluated as giving, and the allocations from two respondents in the second dictator game were evaluated as repaying friends and strangers. The results indicated that children did not have any specific social preferences for friends in giving and repaying but had altruistic and fair preferences for giving to strangers, and strangers had egoistic preferences in repaying. Furthermore, children allocated more to strangers than to friends and allocated more in peer presence. Besides, friends positively reciprocated to proposers in peer absence and repaid less in peer presence. However, strangers consistently repaid less regardless of whether peers were present or not. These results provide more evidence for the assumption of weak ties in giving and demonstrate the strength of strong ties in repaying. These findings enhance our understanding of the interplay of childhood interactions in the development of early relationships.

同伴关系和同伴存在对学龄前儿童三合会互动中给予和回报的影响

这项研究旨在评估学龄前儿童之间动态人际互动中的社会偏好，并研究同伴关系（朋友与陌生人）和同伴在场（同伴在场与同伴在场）对捐赠和还款的影响。九十九个孩子参加了一个三合会游戏，其中包括两个混合独奏游戏。来自第一个独裁者游戏的提议者的分配被评估为给予，而来自第二个独裁者游戏的两个受访者的分配被评估为偿还朋友和陌生人。结果表明，孩子在交往和偿还方面对朋友没有任何特定的社会偏好，但是在向陌生人奉献方面具有利他和公平的偏好，而陌生人在偿还方面具有利己主义的偏好。此外，孩子们对陌生人的分配要多于对朋友的分配，并且在同伴的陪同下分配更多。此外，朋友们在同伴缺席的情况下积极地向求婚者表示感谢，而在同伴不在场时的报酬较少。但是，无论是否有同伴，陌生人的报酬一直较少。这些结果为假设给予中存在弱关系提供了更多证据，并证明了牢固关系在偿还中的优势。这些发现增强了我们对早期人际关系发展中儿童互动的相互作用的理解。这些结果为假设给予中存在弱关系提供了更多证据，并证明了牢固关系在偿还中的优势。这些发现增强了我们对早期人际关系发展中儿童互动的相互作用的理解。这些结果为假设给予中存在弱关系提供了更多证据，并证明了牢固关系在偿还中的优势。这些发现增强了我们对早期人际关系发展中儿童互动的相互作用的理解。
