In 6 experiments, the performance of male rats in a 12-arm radial maze was examined. The focus of study was the extent to which the spatial location of individual baited maze arms was determined before the rat was exposed to the extramaze visual cues corresponding to the arm, and thereby guided the rat toward the location of baited arms. Such spatial guidance of choice behavior implies a spatially organized cognitive representation of maze arms (i.e., a cognitive map). A higher level of spatial guidance was found when visual access to extramaze cues was restricted than when it was unrestricted. There was no evidence of a difference between the level of spatial guidance in the context of working memory performance and reference memory performance. Some evidence that intramaze cues contributed to microchoice guidance was found. However, spatial guidance, under at least some conditions, is best explained in terms of cognitive mapping.
在6项实验中，对雄性大鼠在一个12臂放射状迷宫中的表现进行了检测。研究重点在于，在大鼠接触到与迷宫臂相对应的迷宫外部视觉线索之前，各个有诱饵的迷宫臂的空间位置被确定的程度，以及这是否会引导大鼠找到有诱饵的臂的位置。这种对选择行为的空间引导意味着对迷宫臂有一个空间组织化的认知表征（即认知地图）。当对迷宫外部线索的视觉接触受到限制时，发现空间引导水平高于不受限制时。没有证据表明在工作记忆表现和参考记忆表现的背景下，空间引导水平存在差异。发现了一些迷宫内部线索有助于微观选择引导的证据。然而，至少在某些条件下，空间引导最好用认知地图来解释。
