Spinal rats exposed to an instrumental avoidance routine in a counterbalanced Horridge paradigm were able to achieve successively higher criteria. Both experimental and yoked control animals were capable of instrumental avoidance conditioning to incremental criteria; experimental animals exhibited retention of the task when tested. During acquisition, naive experimental animals were superior in performance to previous control animals. Due to the use of a counterbalanced Horridge paradigm, the effectsof sensitization and response variability are probably not sufficient to explain all of the results of this experiment. The data suggest that both graded acquisition and retention occur at the spinal level.
在平衡的霍里奇范式中接受工具性回避程序训练的脊髓损伤大鼠能够达到相继更高的标准。实验动物和配对对照动物都能够对递增标准进行工具性回避条件反射；实验动物在测试时表现出对任务的记忆。在习得过程中，未经训练的实验动物在表现上优于先前的对照动物。由于使用了平衡的霍里奇范式，敏感化和反应变异性的影响可能不足以解释本实验的所有结果。数据表明，分级习得和记忆在脊髓水平上都会发生。
