This paper introduces R&W Simulator version 4, which extends previous work by incorporating context simulation within standard Pavlovian designs. This addition allows the assessment of: (1) context-stimulus competition, by treating contextual cues as ordinary background stimuli present throughout the whole experimental session; (2) summation, by computing compound stimuli with contextual cues as an integrating feature, with and without the addition of specific configural cues; and (3) contingency effects in causal learning. These new functionalities broaden the range of experimental designs that the simulator is able to replicate, such as some recovery from extinction phenomena (e.g., renewal effects). In addition, the new version permits specifying probe trials among standard trials and extracting their values.
本文介绍了 R&W 模拟器版本 4，它通过在标准巴甫洛夫设计中纳入情境模拟，扩展了之前的工作。这一新增功能允许评估：(1) 情境-刺激竞争，通过将情境线索视为整个实验过程中存在的普通背景刺激来处理；(2) 叠加，通过计算具有情境线索的复合刺激作为一个整合特征，同时不添加特定的组态线索；以及 (3) 因果学习中的关联效应。这些新功能拓宽了模拟器能够复制的实验设计范围，例如一些从消退现象中恢复的现象（例如，更新效应）。此外，新版本允许在标准试验中指定探测试验，并提取它们的值。
