Post-conflict (PC) affiliation has been demonstrated in a number of Old World monkeys and apes, but very little is known about the occurrence of the phenomenon in New World monkeys. This study examined 282 PC interactions after spontaneous conflicts around feeding time in two family groups (N = 12) of captive common marmosets, Callithrix jacchus jacchus. We found an overall corrected conciliatory tendency of 31%. Selective attraction was seen: former opponents met significantly more often in PCs than in matched controls (MCs) (27% and 16%, respectively). There was no difference in the occurrence of PC affiliation between dyads consisting of parent-offspring constellations compared to offspring-offspring constellations. PC affiliative behaviors were seen in the first three minutes following conflict termination, and consisted mainly of proximity, play invitations, and food transfer. Notably, former opponents remained within arm's reach after 17% of conflicts. Affiliation was more likely to follow after conflicts involving play issues. The functional importance of the PC affiliation in marmosets remains to be examined.
冲突后（PC）的亲近行为在一些旧大陆猴和猿类中已有体现，但对于新大陆猴类中该现象的发生情况却知之甚少。本研究观察了两只圈养普通狨猴（Callithrix jacchus jacchus）家庭群体（N = 12）在喂食时间附近自发冲突后的282次PC互动。我们发现总体修正后的和解倾向为31%。观察到了选择性吸引：在PC互动中，前对手相遇的频率显著高于匹配对照组（MC）（分别为27%和16%）。由亲子组合构成的二元组与子代组合构成的二元组之间，PC亲近行为的发生率没有差异。在冲突结束后的前三分钟内出现了PC亲近行为，主要包括靠近、玩耍邀请和食物传递。值得注意的是，17%的冲突后，前对手仍保持在可触及范围内。涉及玩耍问题的冲突后更有可能出现亲近行为。狨猴中PC亲近行为的功能重要性仍有待研究。
