记忆系统中图形不同特征的提取

在长时记忆中，图形的颜色、形状和质地等三个特征可以分开表征。那么，图形的不同特征以何种方式提取?在提取过程中，图形的这些特征被激活的程度是否存在着差异?本研究通过对不同提取线索再认成绩的比较，试图对上述问题进行了探讨。结果表明，长时记忆中，图形的形状、颜色和质地的相对痕迹问无差异，而绝对痕迹不同，形状最强，颜色最弱，质地居中。当然，当图形特征数量增加时，它们之问的相互作用是不可避免的，所以，进一步的研究还应考虑到不同特征组合的提取特点，图形的其他特征(如大小、位置等)的提取特点。

The Retrieval of Different Features of Pictures from Memory

The color, shape and texture of a picture can be represented separately in long term memory. Are there any differences of activation of different features during retrieval from long term memory? The retrieval performances of different recognition cues were compared to the answers to the question. The results indicated that there was no difference of relative memory trace between/among the three features, but significant differences of absolute memory trace were found. With more features taken in an experiment, greater interaction will take place,so more researches need to be made.
