Reconciliation has been demonstrated in all primate species in which the phenomenon has been studied. However, reconciliation has been studied in only two species of callitrichids, and conclusions remain controversial. The first aim of this study has been to find out whether captive cotton-top tamarins (Saguinus oedipus) reconcile, since this is the first such study on this species. We examined 227 conflicts in three family groups (N=19). Instances in which individuals remained together in t=0 (29; 12.8%) were not analyzed. The cotton-top tamarins showed heightened affiliation between opponents in the postconflict periods (PC) compared with matched control (MC) periods (39.88+/-5.12% and 3.18+/-1.27%, respectively), with a corrected conciliatory tendency of 37.17+/-5.37%, and a "time window" that included the first 180 sec of the PC period. Former opponents were the most likely recipient of affiliative behaviors during the PC periods: 39.83+/-4.26% vs. 11.36+/-5.33% during MC periods. The proportion of attracted pairs (47.13+/-6.25%) was significantly higher than those of dispersed pairs for male-male conflicts (3.79+/-1.79), but not for male-female conflicts (27.31+/-9.32 and 4.82+/-2.9, respectively). In cooperative-breeding species, specific sex-class dyads might differ in how they resolve conflicts.
在所有已研究过该现象的灵长类物种中，均已证实有和解行为的发生。然而，在仅有的两种卷尾猴物种中研究了和解行为，并且结论仍然存在争议。本研究的第一个目的是确定圈养的棉顶狨猴（Saguinus oedipus）是否会和解，因为这是对该物种的首次此类研究。我们检查了三个家庭群体中的 227 个冲突（N=19）。在 t=0 时个体仍在一起的情况（29 个；12.8%）未进行分析。与匹配对照（MC）期相比，棉顶狨猴在冲突后时期（PC）中表现出了更高的对手之间的亲昵行为（39.88+/-5.12%和 3.18+/-1.27%），其纠正后的和解趋势为 37.17+/-5.37%，“时间窗口”包括 PC 期的前 180 秒。在 PC 期间，前对手最有可能收到亲昵行为：39.83+/-4.26%比 MC 期间的 11.36+/-5.33%多。在雄性-雄性冲突中，吸引对的比例（47.13+/-6.25%）显著高于分散对的比例（3.79+/-1.79%），但在雄性-雌性冲突中则不然（分别为 27.31+/-9.32%和 4.82+/-2.9%）。在合作繁殖的物种中，特定的性别对二联体可能在解决冲突的方式上有所不同。
