Abstract: The present article explored three facets of the relationship, which are the differences, connections and interactions between implicit learning and explicit learning. Implicit learning is originally regarded as a kind of learning from explicit learning because there are some differences between them in phenomenology, experimental operation, neurophysiology and learning mechanism. However, in recent years, though the independent status of implicit learning has been sufficiently proved, researches have obtained more and more evidences to support the relativity of the differences between implicit and explicit learning. In fact, they are of close connection and often interacted with each other. That is, a real learning task is a combination of implicit and explicit learning. In the end, the present author stated a new viewpoint, the trade-off phenomenon between implicit and explicit learning.
