The experiments were conducted
3、 by a psychologist, John B.Calhoun, and his associates. In each of these experiments, an equal number of male and female adult rats were placed in an enclosure and given an adequate supply of food, water, and other necessities. The rat populations were allowed to increase. Calhoun knew from experien
4、ce approximately how many rats could live in the enclosures without experiencing stress due to overcrowding. He allowed the population to increase to approximately twice this number. Then he stabilized the population by removing offspring that were not dependent on their mothers. He and his associat
5、es then carefully observed and recorded behavior in these overpopulated communities. At the end of their experiments, Calhoun and his associates were able to conclude that overcrowding causes a breakdown in the normal social relationships among rats, a kind of social disease. The rats in the experim
6、ents did not follow the same patterns of behavior as rats would in a community without overcrowding.The females in the rat population were the most seriously affected by the high population density: They showed deviant maternal behavior: they did not behave as mother rats normally do. In fact, many
7、of the pups, as rat babies are called, died as a result of poor maternal care. For example, mothers sometimes abandoned their pups, and, without their mothers care, the pups dieD.Under normal conditions, a mother rat would not leave her pups alone to die. However, the experiments verified that in ov
8、erpopulated communities, mother rats do not behave normally. Their behavior may be considered pathologically diseased.The dominant males in the rat population were the least affected by overpopulation. Each of these strong males claimed an area of the enclosure as his own. Therefore, these individua
9、ls did not experience the overcrowding in the same way as the other rats diD.The fact that the dominant males had adequate space in which to live may explain why they were not as seriously affected by overpopulation as the other rats. However, dominant males did behave pathologically at times. Their
10、 antisocial behavior consisted of attacks on weaker male, female, and immature rats. This deviant behavior showed that even though the dominant males had enough living space, they too were affected by the general overcrowding in the enclosure.Non-dominant males in the experimental rat communities al
11、so exhibited deviant social behavior. Some withdrew completely; they moved very little and ate and drank at times when the other rats were sleeping in order to avoid contact with them. Other non-dominant males were hyperactive; they were much more active than is normal, chasing other rats and fighti
12、ng each other. This segment of the rat population, tike all the other parts, was affected by the overpopulation. The behavior of the non-dominant males and of the other components of the rat population has parallels in human behavior. People in densely populated areas exhibit deviant behavior simila
13、r to that of the rats in Calhouns experiments. In large urban areas such as New York, London, Mexican City, and Cairo, there are abandoned children. There are cruel, powerful individuals, both men and women. There are also people who withdraw and people who become hyperactive. The quantity of other
14、forms of social pathology such as murder, rape, and robbery also frequently occur in densely populated human communities. Is the principal cause of these disorders overpopulation? Calhouns experiments suggest that it might be. In any case, social scientists and city planners have been influenced by
