Using techniques developed by Hall (1975) and modified by Diaz (1991), we maintained rat pups in total social isolation from the time they were 2 or 3 days of age until they were 42 days old. We found that rat pups reared in social isolation exhibited susceptibility to social enhancement of food preference indistinguishable from that exhibited by normally reared rat pups. These data suggest that development of a tendency to use conspecifics as sources of information about what foods to eat does not depend upon previous experience either of interaction with conspecifics or of feeding in social situations.
我们采用由霍尔(1975年)研发并经迪亚兹(1991年)改良的技术,将新生大鼠从2或3日龄起一直饲养在完全社会隔离的环境中,直至它们42日龄。我们发现,在社会隔离环境中饲养的新生大鼠,其对食物偏好的社会增强效应的易感性,与正常饲养的新生大鼠表现出的易感性并无差异。这些数据表明,将同种个体作为食物选择信息来源的倾向的发展,并不依赖于此前与同种个体互动的经历,也不依赖于在社会环境中进食的经历。
