在实验 1 和 2a 中，大鼠在一个矩形池中接受 A+/AX- 辨别，池中的对角有两个水下平台（A+ 试验的正确角）。对于 AX- 试验，将大鼠放置在没有平台的水池中，但在正确的角落有相同的标志 X。随后，地标 X 在实验 I 中通过了抑制的总和和延迟测试。在实验 2a 中完成区分后，将平台放置在矩形正确角上的相同地标附近。这些标志是用于超级适应组辨别训练的标志（AX+ 试验），但对于对照组来说，它们是新颖的（AY+ 试验）。在没有地标和平台的水池中进行的最终测试中，超级适应组比对照组花费了更多的时间来搜索正确的角落。这一发现在实验 2b 的风筝形水池中得到了复制，证明了通过水池形状产生的线索的标志 X 成功进行了超调节。结果对 Miller 和 Shettleworth (2007) 的理论提出了问题。
In Experiments 1 and 2a rats received an A+/AX- discrimination in a rectangular pool with two submerged platforms in diagonally opposite corners-the correct corners-for A+ trials. For AX- trials, rats were placed in the pool without the platforms but with identical landmarks, X, in the correct corners. Landmark X subsequently passed both a summation and retardation test for inhibition in Experiment I. Upon completion of the discrimination in Experiment 2a, the platforms were placed near identical landmarks in the correct corners of the rectangle. The landmarks were those used for discrimination training for a superconditioning group (AX+ trials), but for a control group they were novel (AY+ trials). During a final test in the pool without the landmarks and the platforms, the superconditioning group spent more time than the control group searching in the correct corners. This finding, which was replicated in a kite-shaped pool in Experiment 2b, demonstrates successful superconditioning by landmark X of the cues created by the shapes of the pools. The results pose a problem for the theory of Miller and Shettleworth (2007).
