In this research, a system of various levels of task difficulty was set up by a complex rule. Three characteristics of implicit learning were detected with this system: 1 Implicit learning didn't work under the condition of the most difficult task. 2 When the task became easier, implicit learning started working on some level of task difficulty. 3 The efficiency of implicit learning would become higher if the task became easier; but there was a limit to the efficiency of implicit learning.

本研究利用自行设计的复杂规则产生出不同难度的任务系统，进而通过实验阐明了内隐学习的三个特征：在任务难度极大的情况下，内隐学习并不发挥作用；在任务难度降低到一定程度的时候，内隐学习开始发挥作用，这仿佛是一个"阈限"；随着任务难度逐渐降低，内隐学习的效率也随着提高，但是最终停止在一个较高的水平而不再继续上升。
