内隐序列学习的表征机制及年龄效应研究

该研究从年龄效应这一独特视角探讨了内隐序列学习的表征机制。结果表明:(1)内隐序列学习存在具体联结和抽象层级编码双重表征机制,且在该研究中以抽象编码为主;(2)老、青、幼三组被试的内隐序列学习无显著差异,间接支持了具体联结机制不起主要作用的结论。该研究的推论是:(1)内隐序列学习的表征是一个遵循“最优级编码”的动态过程;(2)该过程不涉及注意机制和短时记忆。

A Research on the Representation Mechanisms and Age Differences of Implicit Learning of Sequence Knowledge

The article discusses the representation mechanisms of implicit learning of sequence knowledge by testing the effects of aging.Two results are obtained:(1) Both association mechanism and hierarchical encoding mechanism work in the implicit learning process of sequence knowledge,and the latter plays a more important role in this research.(2) No significant difference of implicit learning is found among the three groups of subjects of different ages,which supports the first result indirectly.Also,two inferences are made:(1) Implicit learning of sequence knowledge has a dynamic process,in which the principle of optimal coding is obeyed.(2) Attention mechanism and short-time memory are not involved in the process.
