研究表明，皮质醇浓度在竞争性相互作用过程中会发生特征性变化;我们的目的是找出玩耍的情况如何影响唾液中这种激素的浓度。本实验研究了狗在与其主人玩耍的情况下的行为和皮质醇浓度的变化。在该实验中，工作犬根据其工作类型分为两组，即警犬和边防犬。我们发现，老年警犬的皮质醇浓度显著增加，而成年边防犬的激素水平下降，这表明与训犬员玩耍对两组犬都有影响，但有趣的是，这种影响是相反的。行为分析显示，只有在人类处理器的行为在游戏过程中的差异，而行为分析没有发现显着差异，在两组狗，除了老边防犬一般需要更多的时间来开始玩比老警犬。在游戏过程中，警察主要是在管教他们的狗，而边防警卫则是在真正地和他们玩（包括亲密和深情的行为）。我们的研究结果与最近的研究结果一致，这些研究表明，与控制，权威或侵略相关的行为会增加皮质醇浓度，而游戏和亲和行为会降低皮质醇水平。(C)2008年爱思唯尔公司All rights reserved.
It has been shown that cortisol concentrations change characteristically in the course of agonistic interactions; our aim was to find out how a playful situation may affect concentrations of this hormone in the saliva. We studied dogs' behavior and the changes of cortisol concentrations in a play situation, where the dogs played with their handier for 3 min with a tug toy. hi this experiment working dogs were divided into two groups by the type of their work, namely police dogs and border guard dogs. We found that the cortisol concentrations of old police dogs significantly increased, while the adult border guard dogs' hormone levels decreased, which shows that playing with the handler has an effect on both groups, but interestingly this effect was opposite. Behavior analysis showed differences only in the behavior of the human handlers during the play sessions, while the behavior analysis did not reveal significant differences in the two groups of dogs, except that old border guard dogs generally needed more time to begin playing than old police dogs. During the play sessions police officers were mainly disciplining their dogs, while the border guards were truly playing with them (including affiliative and affectionate behavior). Our results are in accordance with those of recent studies, which show that behaviors associated with control, authority or aggression increase cortisol concentrations, while play and affiliative behavior decrease cortisol levels.
