时序信息提取机制的探索

INVESTIGATION INTO THE RETRIEVAL MECHANISM OF TEMPORAL ORDER INFORMATION

对时序信息加工的经典研究是采用新近性判断范型，结果发现其提取机制是以新近性为基础的逆向串行搜索过程。本研究采用新近性判断范型和早远性判断范型对时序信息的提取机制进行了深入的考察，结果表明：（ｌ）提取时序信息既存在逆向串行搜索，又存在顺向串行搜索；（２）早远性判断和新近性判断任务对不同部分时序信息恢复的效应不同，其中早远性判断易化早远部分，新近性判断易化新近部分──表现为对相应部分辨别力的提高和正确反应潜伏期的缩短；（３）在不同的时序信息提取任务中，被试会根据具体条件进行反转反应。

The temporal order information is recovered by a recency-based,backward serial retrieval process,according to the previous classic JOR(judgment of recency)study.The retrieval mechanism of temporal order information from short-term memory was examined carefully with the JOR and JOE(judgment of earliness)paradigms.The results showed:(1)Order information can be retrieved by either a backward serial scan or a forward serial search;(2)JOE and JOR had different effects on different parts of the study list,that is,the JOE enhanced the earlier part,and JOR strengthened the latter part,showing that they raise the corresponding d'and shorten its RT;(3)Subjects transform their reaction in special situations,depending on the memory representation of the items.
