序列位置内隐学习产生机制的实验研究

STUDIES ON THE MECHANISM OF IMPLICIT LEARNING OF SEQUENCE POSITIONS

内隐学习是当今认知和学习领域继内隐记忆之后又一重要的研究课题。该研究利用序列反应时研究程式，通过两个实验，对序列位置内隐学习产生的机制进行了探讨。结果表明：（１）在序列反应时任务程式中，随着反应一刺激间隔的延长，序列位置内隐学习的学习量逐渐减少；（２）异形同模式迁移组和异形异模式迁移组被试间内隐学习量无显著差异，被试未能内隐地习得抽象的序列模式。说明序列位置内隐学习产生的基础是水平联结，在该实验条件下没有发现垂直联结存在的证据。

Implicit learning, after implicit memory, is becoming one of the most important research topics in the current field of cognition and learning. Using serial reaction time (SRT) paradigm, we conducted two experiments to study the mechanism of implicit learning of sequence positions. The results showed: (1) In the serial reaction time task, with the lengthening of response-stimulus interval (RST), the amount of implicit learning decreased. (2) Subjects' implicit learning score of isomorphic transfer group was almost the same with that of nonisomorphic transfer group, the subjects could not implicitly acquire the underlying abstract pattern of sequence locations. These indicated that implicit learning of sequence positions mainly depended on horizontal associations of events, not vertical associations.
