Objective: To investigate the memory image of sophistication and class information extraction mechanism. Methods: Chinese characters-letters types of materials and plant-animal characters class materials were used, two kinds of test materials for 34 tests, respectively, the test results as the statistical analysis. Rusults: Chinese characters-the letters are part of the reporting category is always prompt partial-report superiority, while the plant-animal category prompts only be when a single arrangement in two categories. Conclusion: the type of image information stored in memory only based on visual-spatial characteristics of this type of automated processing of category information (such as Chinese characters-letters category), and its extraction process is the "first choice, after identifying" plus cognitive.%目的:探讨图像记忆中类别信息的精细程度及其提取机制.方法:采用汉字——字母类别材料和植物——动物汉字类别材料2种实验材料,分别对34名被试作实验,将实验后的结果作为统计分析.结果:汉字——字母类别提示,始终都有部分报告优势效应,而植物——动物类别提示,只有在2类别单一排列时才有.结论:图像记忆中储存的类别信息,只有基于视觉——空间特征这类自动化加工的类别信息(如汉字——字母类别)的,其提取过程是“先选择、后识别”的认知加工.
