Abstract: Parental investment is an important factor in the early social environment of offspring,and profoundly and persistently influences a broad range of developmental trajectories. Changes in parental investment can result from parental absence such as via maternal,paternal or early deprivation. Here,we review and summarize the effects of parental absence on the development of emotion,cognition,social behavior and neuroendocrine patterns in parentally-deprived offspring. Specifically,we examine the impact on aggression,pair bonding and parental care at adulthood. It is clear that several significant questions regarding the effects of parental absence remain,and these are summarized. These studies provide insights into the underlying mechanisms of abnormal behavior and inform the scientific management of wild animals and those housed in laboratories

摘要： 亲本投资作为一种早期社会环境对个体发育产生显著的影响。而某些原因会导致哺乳类亲本缺失,造成亲本投资改变。最近有关亲本缺失对子代的影响有较多的研究,本文主要综述了早期母本剥夺、父本剥夺和早期隔离分别对子代成年后情绪、认知及攻击行为、育幼行为和配偶关系的建立等多种社会行为的影响,并总结了这些早期发育的社会环境对神经内分泌的效应,并指出本领域需要解决的问题,希望有助于正确认识哺乳类不同亲本投资对后代行为的影响及相关神经内分泌机制。以上研究可为哺乳类异常行为的发生机制的理解提供重要线索,也为野生动物和实验动物的科学管理提供重要启示。
