雄性和雌性小鼠被隔离和过度拥挤1周和4周，以确定[1]，种群密度将对器官重量和儿茶酚胺与行为变化的关系产生什么影响，以及[2]，什么方式可能会影响这些相互作用。唯一一致的显着的生理和生化效应是与性别有关的，不会因环境的变化而改变。然而，只有雄性小鼠才会出现与性别相关的打斗行为，这需要改变环境，即孤立，才能表现出来。因此，没有可测量的生化效应与行为的改变有关。
Male and female mice were subjected to isolation and excessive overcrowding for 1-week and 4-week periods to determine [1], what effect population density would have on organ weights and catecholamines in relationship to behavioral changes, and [2], in what manner time might influence these interactions. The only consistent significant physiologic and biochemical effects were sex-related and were not modified by changes in the environment. However, fighting behavior, a sex-related characteristic that was only elicited in the male mice, required a change in the environment, i.e. isolation, to be expressed. Thus, no measurable biochemical effect could be associated with a change in behavior.
