This paper exploits a unique ongoing experiment to analyze the effects of early rearing conditions on physical and mental health in a sample of rhesus monkeys (Macaca mulatta). We analyze the health records of 231 monkeys that were randomly allocated at birth across three rearing conditions: mother rearing, peer rearing, and surrogate peer rearing. We show that the lack of a secure attachment relationship in the early years engendered by adverse rearing conditions has detrimental long-term effects on health that are not compensated for by a normal social environment later in life.
本文利用一项正在进行的独特实验,分析了幼年饲养条件对恒河猴(Macaca mulatta)生理和心理健康的影响。我们分析了 231 只猴子的健康记录,这些猴子在出生时被随机分配到三种饲养条件下:母猴抚养、同伴抚养和替代同伴抚养。研究结果表明,不良饲养条件导致早年缺乏安全的依恋关系,对健康产生了长期的不利影响,而正常的社会环境并不能弥补这一影响。
