对RM Nosofsky和TJ Palmeri（1997）的基于样本的随机游走（EBRW）快速分类模型进行了扩展，使其能够考虑整维刺激之间的快速同异判断。根据该模型，同异判断的一个重要组成过程是人们在记忆中储存经验相同和不同的成对对象的个体例子。这些范例对是根据它们与当前呈现的对象对的相似程度从记忆中检索的。检索到的对驱动一个随机行走过程，以做出相同或不同的决定。EBRW预测正确，同样的反应是更快的对象躺在孤立的相似性空间的密集区域。该模型还正确预测了相同身份与相同类别指令的效果，并对观察者过去对特定相同和不同对象对的经验敏感。（PsycINFO数据库记录（c）2016阿帕，保留所有权利）
RM Nosofsky and TJ Palmeri's (1997) exemplar-based random-walk (EBRW) model of speeded classification is extended to account for speeded same–different judgments among integral-dimension stimuli. According to the model, an important component process of same–different judgments is that people store individual examples of experienced same and different pairs of objects in memory. These exemplar pairs are retrieved from memory on the basis of how similar they are to a currently presented pair of objects. The retrieved pairs drive a random-walk process for making same–different decisions. The EBRW predicts correctly that same responses are faster for objects lying in isolated than in dense regions of similarity space. The model also predicts correctly effects of same-identity versus same-category instructions and is sensitive to observers' past experiences with specific same and different pairs of objects.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
