Individually and group-reared male rats were behaviourally compared after various periods of different housing, (i) during a first exposure to the new environment, and (ii) after habituation (two repetition trials) to the situation, during a fourth exposure in a slightly modified test-box. Compared to group-housed controls an elevated locomotor activity upon the first exposure and a reduced reaction in response to the slight modifications were found in individually housed rats.
将单独饲养和群居饲养的雄性大鼠在经历不同时长的不同饲养方式后进行行为学比较，（i）在首次暴露于新环境期间，以及（ii）在对该环境形成习惯化（两次重复试验）后，于经过轻微改造的测试箱中进行第四次暴露期间。与群居对照大鼠相比，单独饲养的大鼠在首次暴露时表现出更高的运动活性，而对轻微改造的反应则有所降低。
