系列包含的项目数、项目之间的间隔时间与系列位置效应

THE LENGTH OF THE LISTS, THE INTERVAL OF ITEMS AND THE SERIAL POSITION EFFECTS

以中国汉字为材料 ,考察系列包含的项目数、项目之间的时间间隔与系列位置曲线不同部分记忆性质分化的关系。结果表明 ,(1)提取过程的重要性。 (2 )在包含 11个项目、并且项目之间的时间间隔为 40 0毫秒的系列中 ,系列位置曲线的首因部分表现为联想记忆的性质 ,是依赖于线索的提取 ;近因部分表现为绝对记忆的性质 ,是依赖于记忆痕迹的提取。 (3)系列位置曲线不同部分记忆性质的分化 ,于系列包含的项目数和项目之间的间隔时间有关 。

The purpose of this study was to examine the cognitive mechanism underlying the serial position effects with Chinese characters. The results demonstrated that:1) The important role of retrieval processes for serial items recall. 2) When the length of the list was 11 Chinese characters, and the interval of items was 400ms, the primacy effect and recency effect belonged to the associative memory and absolute memory respectively. The retrieval for the prime items depended mainly on the context cues, but the retrieval for the recent items depended mainly on the memory trace. 3) The interaction between the length of the list and the interval of items for the nature's differentiation in different parts of the serial position curve.
