【摘要】 第一部分通过视觉工作记忆研究现状的整体分析,然后探讨图形的形状与颜色特征在的存储与整合状况。同时,为了增加图形的视觉信息含量,完善客体构成的纯视觉特征维度,以及控制空间特征造成的位置差异,因此引入纹理特征,进一步对客体工作记忆存储单位及其整合加工机制进行系统验证,以便对客体工作记忆的存储表征有更进一步的了解和认知。第二部分通过相关研究的分析,发现局限和不足,提出问题和假设,然后实验验证。实验一对由纹理、颜色和形状三种不同维度特征构成的客体进行存储与整合研究,以探讨纹理特征能否与颜色特征和形状特征一样在客体工作记忆中得到独立存储,三种维度特征整合的客体的表征情况；实验二中,由于实验一验证了纹理的存储与颜色,形状一样在客体工作记忆中有独立的存储机制。本实验通过控制组成图形的特征维度量和客体数量,来验证图形所含信息量(特征维度量和客体数量)是否对客体工作记忆的存储产生影响。第三部分对两个实验结果进行分析和讨论以后,得出如下结论：1.纹理,颜色与形状的存储机制是整合客体。而在现实中应该是存在两种水平,一种水平是视觉信息可以并行加工,首先会对特征进行加工存储,而后对特征整合。另一种水平是视觉信息进行系列加工,这样就难以实现整合客体的存储方式。本研究的结论属于前者,因为整合的是纯视觉客体。2.纹理,颜色与形状在客体工作记忆中可以独立存储,拥有自己的子系统,但加工程度是不同的,客体工作记忆对于颜色的加工早于,形状与纹理的加工,同时记忆效果还好,因此表现出颜色的子系统优势。4.纯视觉客体在客体工作记忆中的容量是有限的,它会随着客体信息含量增加而减少,即图形的特征维度或者数目会对客体工作记忆的存储容量产生影响。更多还原

【Abstract】 The first part analyzed the status of the study on visual working, invistaged the storage and integrate of the shape and color features,meanwhile selected another feature—texture in order to increase the visual information content, to enhance the dimension of the object, which constitute a pure visual features objects, as well as to control the different spatial information, and further validated the unit of visual working memory capacity and their binding mechanism, so that to better understood and cognizedright the storage of object working memory storage.The second part through relevant research analysis found limitations and weaknesses.asked questions and assumptions, and finished experiment. In the experimentⅠ, we studied the storage and bound of the objects which were structured three different features on texture, color and shape.explored whether the feature of texture are an independent storage system,like color and shape and how to integrate an object with three dimension features.In the experimentΠ,by controlling the amount of the composition features and the number of the objects’ dimensions,we verified whether the amount of information contained in graphics (the number of dimensions and the objects) had an impact with the storage of object working memory.The third part discussed the results of the two experiments, then came to conclusion as follows:1.Texture,color and shape were stored as an integrated-object in the visual working memory.In reality, there should be two levels of storage,one was parallel process,the other was serial process.The conclusions of this study belong to the former.2.The storage levels of texture, color and shape were different in object working memory.In contrast to texture and shape, color was stored earlier and better. The result suggested color subsystem priority.3.The capacity of pure visual objects was limited in the object working memory.更多还原
