项目等距呈现过程中的系列位置效应

以中国汉字为材料，利用刘英茂提出的向前和向后联想的方法，证明在不同呈现时间和不同间隔时间条件下，系列位置曲线中首因效应和近因效应性质的分化过程。结果说明，系列位置曲线的近因部分对时间变化更为敏感，表现为绝对记忆的性质。系列位置曲线中首因效应和近因效应性质的分化，取决于项目呈现时间、项目间隔时间和系列包含的项目数。

SERIAL POSITION EFFECTS DURING ITEMS PRESENTATION IN EQUAL TIME

Using the forward and backward associative method proposed by Liu Inmao, we examined the nature of primacy and recency effect in different presentation and interval times sitution with Chinese characters. The results showed that the recency effect of the serial position effect was sensitive to the changing of time, and the recency effect belonged to absolute memory. The nature of primacy and recency effect depended on the item presentation bine, the interval bine and the item number of the serial.
