用雄性大鼠进行的四个实验研究了涉及触觉维度（A、B、C、D、E）的感知学习，其中A表示连续体的一端（例如，粗糙地板）和E另一个（例如，光滑的地板）。在实验1中，预先暴露于A和E的大鼠比未预先暴露的大鼠更容易学会对它们之间的食欲区分。实验2a表明，预先暴露于B和D的大鼠比预先暴露于A和E的大鼠更容易获得A和E之间的区分;在实验2b中，相同的预先暴露处理对获得B和D之间的区分没有影响。在实验3a和3b中，预先暴露于C的大鼠比没有预先暴露的大鼠更容易学会区分A和E。实验4表明，预暴露于纹理（例如，B）与待区分纹理相邻（例如，C和E）促进了他们之间的歧视相对于预先暴露于他们的中点（D）。这些新的感知学习效果被解释为反映了纹理维度的概念元素之间的处理的重新分配。
Four experiments with male rats investigated perceptual learning involving a tactile dimension (A, B, C, D, E), where A denotes 1 end of the continuum (e.g., a rough floor) and E the other (e.g., a smooth floor). In Experiment 1, rats given preexposure to A and E learned an appetitive discrimination between them more readily than those not given preexposure. Experiment 2a showed that rats preexposed to B and D acquired a discrimination between A and E more readily than those preexposed to A and E; and in Experiment 2b the same preexposure treatments had no effect on the acquisition of a discrimination between B and D. In Experiments 3a and 3b, rats given preexposure to C learned a discrimination between A and E more readily than those not given preexposure. Experiment 4 demonstrated that preexposure to a texture (e.g., B) that was adjacent to the to-be-discriminated textures (e.g., C and E) facilitated a discrimination between them relative to preexposure to their midpoint (D). These novel perceptual learning effects are interpreted as reflecting a redistribution of processing between the notional elements of the texture dimension.
