摘要
本文观察了在成年后进行群体隔离的大白鼠与群居鼠在摄食、饮水、睡眠等方面的行为差异。着重观察了社会应激对成年后进行群体隔离的动物的行为的影响,以研究群体隔离时动物的年龄与过去生活经验是不是动物在社会应激时发生的行为改变的关键因素。 结果表明:群居与隔离两种环境对动物摄食、饮水和体重无明显影响,但隔离动物睡眠时间较群居动物短。即使在成年后进行群体隔离、社会应激对隔离动物的摄食、饮水、睡眠和攻击性行为的影响也比群居组明显。但进行群体隔离时动物的年龄和隔离前有较长时间的群居生活经验可大大减轻社会应激时行为反应的强度,也可使适应过程发生得快些。这说明早期环境和过去生活经验的重要性。社会应激影响饮水和摄食的方式随年龄而改变,年龄较大的群居鼠对社会应激的适应可能比年龄较轻的群居鼠差。
After reaching 4 months old, the grown-up albino rats weredivided, some housed in isolation and some in gregarious groups for 8weeks. Observations were made on their behavioral patterns of eating,drinking and sleeping. Thereafter all the rats were regrouped, putting 4strangers in one cage as a means of creating social stress to study itseffects on, the behavioral patterns of rats from both catagories.It wasfound that the behavioral changes in eating, drinking and sleepinginduced by social stress in isolated rats were more significant thanthose in gregarious rats,even though social isolation was carried outafter the rats were grown-up. Compared with gregarious rats, isolatedrats were characterized by stronger aggressive behavior. In comparisonwith the rats of which social isolation was carried out in early life(one month old), the behavioral changes during social stress in thegrown-up rats previously kept in social isolation were, however, lesssevere and they seemed to experience a shorter adaptation process.
