The study examines the suggestion that isolated male mice act in a similar way to dominant males. Behaviours of isolated, dominant and subordinate mice were compared in an open-field, emergence test, activity monitor and aggression test. In a number of ways the behaviour of both isolates and dominants differed from subordinates. Subordinates were more active on the first day in the open-field, but they habituated relatively quickly. In contrast, both the isolates and dominants were initially relatively inactive, but reacted to a novel situation for longer. There were, however, no circadian variations in activity in the three categories of mice. Unlike the subordinates, both dominants and isolates displayed aggression towards male mice; these last two categories of mice also had heavier sex accessory glands. It was concluded that the behaviour of isolated and dominant mice is very similar, at least under the conditions of this experiment.
该研究检验了这样一种观点，即独居雄性小鼠的行为方式与占主导地位的雄性小鼠相似。在旷场实验、出洞试验、活动监测和攻击试验中，对独居、占主导地位和从属地位的小鼠的行为进行了比较。在许多方面，独居小鼠和占主导地位的小鼠的行为与从属小鼠不同。从属小鼠在旷场实验的第一天更活跃，但它们相对较快地适应了环境。相比之下，独居小鼠和占主导地位的小鼠最初都相对不活跃，但对新环境的反应持续时间更长。然而，这三类小鼠的活动没有昼夜节律变化。与从属小鼠不同，占主导地位的小鼠和独居小鼠都会对雄性小鼠表现出攻击性；后两类小鼠的性附属腺也更重。研究得出结论，至少在本实验条件下，独居小鼠和占主导地位的小鼠的行为非常相似。
