The relative contributions of social-rearing stimuli (a mother and/or a littermate) and nonsocial-rearing stimuli (a brooder) to the formation and decline of infant kitten attachments were assessed by counting the frequency of distress cries produced by separation from the following rearing conditions: (1) mother-littermate; (2) mother-only; (3) brooder-littermate; and (4) brooder-only. Four male and 4 female kittens were reared in each condition. Each kitten was separated from its rearing condition once a week, from 2 until 5 weeks of age, and placed in open field for 15 min. The frequency of distress cries in both littermate-reared groups did not significantly differ throughout the experiment. The frequency was consistently high until 5 weeks of age when distress cries were significantly reduced. The frequency of distress cries consistently increased in the mother-only-reared kittens with repeated separations, but consistently decreased in the brooder-only-reared kittens. The results were interpreted as being commensurate with the social conditions at the time of separation.
通过统计在与以下饲养条件分离时产生的痛苦叫声的频率，评估了社会饲养刺激（母亲和/或同窝幼崽）和非社会饲养刺激（育雏器）对幼猫依恋形成和消退的相对贡献：（1）母亲-同窝幼崽；（2）仅母亲；（3）育雏器-同窝幼崽；（4）仅育雏器。每种条件下饲养4只雄性和4只雌性小猫。从2周龄到5周龄，每只小猫每周与饲养条件分离一次，并放置在空旷场地15分钟。在整个实验过程中，两个同窝饲养组的痛苦叫声频率没有显著差异。在5周龄之前，频率一直很高，之后痛苦叫声显著减少。在仅由母亲饲养的小猫中，随着分离次数的增加，痛苦叫声的频率持续增加，但在仅由育雏器饲养的小猫中，频率持续下降。结果被解释为与分离时的社会条件相符。
