当前的环境认知理论通常将在线环境与非在线环境区分开来。短暂的空间表征的动态系统和记忆表征的全离线持久系统。在这里，作者提出了额外的证据，这样的2系统理论的背景下，定向障碍范式介绍了R。F. Wang和E. S. Spelke（2000年）。几个实验重复了这一发现，即迷失方向会导致人们对相对方向的估计精度下降。与此相反，这种效应的典型解释表明一个短暂的空间系统的首要地位。目前的结果通常与将其解释为指示从相对精确的在线表示切换到相对粗糙的持久表示的解释更一致。进一步的实验研究了瞬态和持久表征的相对精度，并表明它们之间的切换不需要迷失方向，但也可以通过小至135度的自转产生。
Current theories of environmental cognition typically differentiate between an online. transient. and dynamic system of spatial representation and all offline and enduring system of memory representation. Here the authors present additional evidence for such 2-system theories in the context of the disorientation paradigm introduced by R. F. Wang and E. S. Spelke (2000). Several experiments replicate the finding that disorientation results in a decrease in the precision of people's estimates of relative directions. In contrast to the typical interpretation of this effect as indicating the primacy of a transient spatial system. the present results are generally more consistent with an interpretation of it as indicating a switch from a relatively precise online representation to a relatively coarse enduring one. Further experiments examine the relative precision of transient and enduring representations and show that switching between them does not require disorientation, but can also be produced by self-rotations as small as 135 degrees.
