众所周知，在社会关系密切的物种中，与熟悉的依恋对象分离会刺激生理和行为应激反应。本研究调查了成年普通绒猴与熟悉的群体成员分离以及与陌生的异性同种同居24小时后的激素和声音反应。将所有受试者从其饲养笼中取出，并置于新环境中20分钟。在一组中，绒猴在新环境中暴露于不熟悉的异性伴侣，并在24小时的测试期间与该伴侣保持配对。在其他三组中，绒猴单独经历了新的环境，随后被送回原来的社会或单一住房条件，或与社会群体分开24小时。在分离前一天、分离后30 min、90 min和24 h采集血样。皮质醇反应的差异影响分离的长度和存在的不熟悉的同种。短暂的分离，然后返回社会群体对血浆皮质醇水平的影响最小。所有的绒猴在新的环境中产生高水平的分离呼叫，但呼叫和皮质醇水平之间没有明显的关系。以前在松鼠猴和恒河猴婴儿分离研究中已经注意到，痛苦发声和血清皮质醇的产生之间缺乏时间关系;分离的行为和生理反应在绒猴中似乎也是分离的。此外，分离环境的特征可以差异化地影响成年绒猴的激素反应，而不会差异化地影响它们的行为反应。Am.

In socially‐bonding species, separation from familiar attachment figures is widely known to stimulate a physiological and behavioral stress response. This study investigated the hormonal and vocal responses of adult common marmosets to separation from familiar group members and to 24 hr of cohabitation with an unfamiliar opposite‐sex conspecific. All subjects were removed from their home cages and placed into a novel environment for 20 min. In one group, marmosets were exposed to an unfamiliar, opposite‐sex partner in the novel environment and remained paired with this partner for the 24 hr test period. In three other groups, marmosets experienced the novel environment alone and subsequently were returned to their original social‐ or single‐housing condition, or kept separate from their social groups for a 24 h period. Blood samples were collected the day before, and at 30 min, 90 min, and at 24 h after separation. Cortisol responses were differentially affected by the length of separation and the presence of unfamiliar conspecifics. Brief separation followed by the return to the social group had minimal effect on plasma cortisol levels. All marmosets produced high levels of separation calls in the novel environment, but there was no apparent relationship between calling and cortisol levels. The lack of a temporal relationship between the production of distress vocalizations and serum cortisol has previously been noted in squirrel monkey and rhesus monkey infant separation studies; the behavioral and physiological responses to separation appear to be similarly dissociated in the marmoset. Further, the characteristics of a separation environment can differentially affect the hormonal response by adult marmosets without differentially affecting their behavioral response. Am. J.
