15日龄的大鼠受到三种住房条件之一：母亲和同伴（家庭），同伴，和隔离条件。在24日龄时，所有受试者单独安置。在实验1中，游戏行为进行了监测，在喜欢提出的对。尽管他们严重缺乏社会经验，孤立抚养的受试者并没有表现出混乱玩耍频率的缺陷。它的结论是，基本动机的粗糙和翻滚发挥是相对独立的事先学习大鼠。事实上，他们升高的背接触表明，孤立提出的主题可能有更高的食欲动机发挥。在实验2中，社会动机的水平进行了比较家庭和隔离饲养的动物，使用T型迷宫。与家庭饲养的动物相比，隔离饲养的动物对社会互动奖励的选择可靠性更高。虽然这两个实验的结果并不确定，但它们都表明，长期的社会隔离会增加社交游戏的欲望动机。
Fifteen-day-old rats were subjected to one of three housing conditions: mother-and-peer (family), peer, and isolation conditions. At 24 days of age, all subjects were rehoused individually. In Experiment 1, play behaviors were monitored in like-raised pairs. Despite their gross lack of social experience, isolation-reared subjects did not exhibit a deficit in frequencies of rough-and-tumble play. It is concluded that the fundamental motivation for rough-and-tumble play is relatively independent of prior learning in rats. Indeed, their elevated dorsal contacts suggested that isolation-raised subjects may have higher appetitive motivation for play. In Experiment 2, the levels of social motivation were compared between family- and isolation-raised animals, using a T-maze. The isolation-raised animals made reliably more choices for social interaction reward over food reward than family-raised animals. Although inconclusive, the results from the two experiments suggest that prolonged social isolation increases the appetitive motivation for social play.
