Behavioral profiles of male rats were defined in nine intralitter groups of six individuals at various stages of their development: (a) at pup stage in individual situations (uncomfortable positions) and social situations (removal away from the mother), and (b) at adult stage in a difficult food supply social situation (complete immersion of the food access way). The male population was split into two sets, both at pup stage (the most and the least swift and efficient of each group to overcome uncomfortable situations), and at adult stage (carriers and noncarriers of food in each group tested). Our results showed an important relation between these pup and adult behavioral profiles: the swiftest and most efficient individuals of a group at pup stage adopted more often a food carrier behavioral profile at adult stage. Assumptions about the predictive value of some behavioral features of a young rat in regard to its adult behavioral profile are discussed.
在雄性大鼠发育的不同阶段，对9个同窝幼仔组（每组6只个体）的行为特征进行了定义：(a) 在幼崽阶段，处于个体情境（不舒服的姿势）和社交情境（与母亲分离）时；(b) 在成年阶段，处于食物供应困难的社交情境（食物获取通道完全被淹没）时。雄性大鼠群体在幼崽阶段（每组中克服不舒服情境最迅速高效和最不迅速高效的个体）和成年阶段（每组中测试的食物携带者和非食物携带者）都被分成了两组。我们的结果表明，这些幼崽和成年阶段的行为特征之间存在重要关联：幼崽阶段一组中最迅速高效的个体在成年阶段更常表现出食物携带者的行为特征。文中还讨论了关于幼鼠某些行为特征对其成年行为特征的预测价值的假设。
