Four experiments investigated the swimming behaviour of staggerer mutant mice. The results partially confirmed previous reports that a mouse's swimming is unaffected by the staggerer mutation. In terms of speed and distance there are indeed no measurable differences between normal and staggerer mice, when first placed in the water. The stagger's resistance was however shown to be much lower than a normal's and the genetic difference was also associated with different styles of swimming. Furthermore, whereas the normal mouse's swimming behaviour evolves with increased time in the water, the staggerer's remains constant. The differences are interpreted on the basis of abnormal novelty reactions by the staggerer mutants. Thus, swimming appears to be a better tool for investigating the higher-level cognitive functions of this mutant than terrestrial locomotion.
四项实验研究了蹒跚突变小鼠的游泳行为。结果部分证实了先前的报道，即小鼠的游泳不受蹒跚突变的影响。就速度和距离而言，正常小鼠和蹒跚小鼠首次放入水中时确实没有可测量的差异。然而，蹒跚小鼠的抵抗力远低于正常小鼠，并且这种基因差异还与不同的游泳方式有关。此外，正常小鼠的游泳行为会随着在水中时间的增加而演变，而蹒跚小鼠的游泳行为则保持不变。这些差异是基于蹒跚突变体异常的新奇反应来解释的。因此，与陆地运动相比，游泳似乎是研究这种突变体高级认知功能的更好工具。
