Play behaviours of northern grasshopper mice, Onychomys leucogaster , were observed from 27 to 61 days of age and after a brief period of social isolation. The mice were also observed during a simple test of cricket predation. With the exception of an active play-soliciting response, the play behaviours were quite similar to those described for other rodents. Play declined with increasing age and was strongly potentiated by social isolation. There was no discernable relationship between any of the play measures and efficiency of cricket predation. There were no detectable sex differences in either play or predation.
对北美草甸鼠（白腹林鼠）从27日龄至61日龄以及经过短暂的社会隔离后的玩耍行为进行了观察。在一项简单的捕食蟋蟀测试中也对这些小鼠进行了观察。除了一种积极的求玩反应外，其玩耍行为与其他啮齿动物所描述的行为非常相似。玩耍行为随着年龄增长而减少，并且因社会隔离而显著增强。任何玩耍指标与捕食蟋蟀的效率之间均无明显关系。在玩耍或捕食方面均未检测到性别差异。
