MODIFICATION OF PSYCHOLOGICAL ADAPTATION IN THE LONG-TERM CONSTANCY OF REARING ENVIRONMENT

本研究从比较心理学的角度对行为适应过程进行了初步的探讨。本研究从野外采集了家麝鼩（Suncus murinus）活体样本，并进行了引种繁殖。经过多次驯化试验，初步驯化工作顺利进行。因此，我们准备对动物进行几代人的跟踪调查，以便弄清楚驯化的行为影响。我们为长期研究项目开了一个好头，因为育种初期的成败将主要决定本研究的结果。虽然用于行为分析的数据量不够大，但在驯化的早期阶段，鼩 鼱往往表现出一些不同于驯化的高世代的特征。

This study is an original approach to the process of behavioral adaptation from comparative psychology. In the study, we collected live samples from wild population of the house musk shrew (Suncus murinus) and introduced to breed them for generations. After repeated trail of domestication, early stage of domestication has been proceeding successfully. Therefore, we are ready to follow up animals for generations so that the behavioral effects of domestication could be made clear. We have made a good start for long-run research project, since success or failure of the initial stage of breeding would mostly determine the outcome of this study. Although data size for behavioral analysis is not large enough, shrews of the early stage of domestication tended to show some characteristics which differed from those of advanced generations in domestication.
