Male Syrian hamsters were paired and allowed to interact with a conspecific for 15 min a day for 4 days. On the fifth day, the animals were again paired, but they were kept physically separated by a mesh partition that allowed visual, olfactory, and auditory contact between the animals. Controls were placed with conspecifics on each of the 5 testing days, but the partition between them was never removed. Hamsters that were submissive on days 1-4 exhibited elevated plasma adrenocorticotropin-like immunoreactivity (ACTH-LI), beta-endorphin-like immunoreactivity (B-EP-LI), and cortisol on day 5 even though no fighting occurred on that day. Dominant hamsters did not differ from controls. These data support the hypothesis that there is an important psychological component to the pituitary-adrenocortical response in defeated hamsters.
将雄性叙利亚仓鼠配对，每天让它们与同种仓鼠互动15分钟，共持续4天。在第5天，再次将这些动物配对，但用一个网状隔板将它们隔开，使它们能进行视觉、嗅觉和听觉接触。对照组在5个测试日中的每一天都与同种仓鼠放在一起，但它们之间的隔板从未被移除。在第1 - 4天表现顺从的仓鼠，即使在第5天没有发生打斗，其血浆促肾上腺皮质激素样免疫反应性（ACTH-LI）、β-内啡肽样免疫反应性（B-EP-LI）和皮质醇水平也有所升高。占主导地位的仓鼠与对照组没有差异。这些数据支持了这样一种假设，即被击败的仓鼠的垂体-肾上腺皮质反应存在重要的心理成分。
