非联想学习的三种形式（习惯化、去习惯化和敏感化）通常由双过程观点来解释，其中一个递减过程产生习惯化，一个促进过程产生去习惯化和敏感化。这种观点的一个关键预测是，去适应和敏感化应该总是同时发生。然而，我们发现，disabituation和敏化，以及一个额外的过程，抑制，可以在行为上分离的Aaplasia（i）他们的差分时间的发病，（ii）他们的差分敏感性刺激强度，（iii）他们的差分出现在发展过程中。一个简单的双过程的观点不能解释这些结果，而是一个多过程的观点似乎有必要考虑非联想学习在Arachsia。
Three forms of nonassociative learning (habituation, dishabituation, and sensitization) have commonly been explained by a dual-process view in which a single decrementing process produces habituation and a single facilitatory process produces both dishabituation and sensitization. A key prediction of this view is that dishabituation and sensitization should always occur together. However, we show that dishabituation and sensitization, as well as an additional process, inhibition, can be behaviorally dissociated in Aplysia by (i) their differential time of onset, (ii) their differential sensitivity to stimulus intensity, and (iii) their differential emergence during development. A simple dual-process view cannot explain these results; rather, a multiprocess view appears necessary to account for nonassociative learning in Aplysia.
