We studied the performance of eight cosmonauts in a mental rotation paradigm with simultaneously presented perspective views of three-dimensional objects. The cosmonauts were tested successively on earth, in microgravity aboard the Russian MIR station and again on earth. Their performance was compared to performance of a control group of five subjects tested on earth on the same dates. We particularly tried to disambiguate the effect of microgravity, procedural bias and practice. Our results show that the microgravity did not alter the mental rotation process. The performance of cosmonauts increased with practice, similarly to the performance of control group's subjects suggesting that the weightlessness did not impair implicit learning as well. Finally, we propose an explanation of previous contradictory results.
我们研究了八名宇航员在一种心理旋转范式中的表现，该范式中会同时呈现三维物体的透视图。这些宇航员先后在地球上、俄罗斯和平号空间站的微重力环境中以及再次回到地球上接受测试。他们的表现与同一天在地球上接受测试的五名对照组受试者的表现进行了比较。我们特别试图厘清微重力、程序偏差和练习的影响。我们的结果表明，微重力并未改变心理旋转过程。宇航员的表现随着练习而提高，这与对照组受试者的表现类似，表明失重也并未损害内隐学习。最后，我们对之前相互矛盾的结果提出了一种解释。
