Contextual control is a key aspect in equivalence research to support the claim that stimuli may have multiple functions or symbols may have multiple meanings. The present study investigated the contextual control of multiple derived stimulus functions in two experiments. In Experiment 1, equivalence classes were formed and one stimulus set from each class was used to establish two different functions: one via positive reinforcement (key‐pressing) and another via negative reinforcement (button clicking), both under contextual control of two different background colors. Later, other stimuli from the equivalence class were presented on those background colors and contextual control of multiple derived stimulus functions was assessed. Experiment 2 added a third background in which no programmed response was reinforced, that is, responses were extinguished. Transfer‐of‐function tests revealed contextual control of three different functions, including derived extinction. Implications for equivalence relations as a behavior‐analytical model of symbolic functioning are discussed.

多个派生刺激函数的等价关系和上下文控制

上下文控制是等价研究的一个关键方面，以支持刺激可能具有多种功能或符号可能具有多种含义的说法。本研究在两个实验中调查了多个派生刺激功能的上下文控制。在实验 1 中，形成了等价类，每个类的一组刺激用于建立两种不同的功能：一种通过正强化（按键）和另一种通过负强化（按钮点击），两者都在两种不同背景的上下文控制下颜色。后来，来自等价类的其他刺激呈现在这些背景颜色上，并评估了多个派生刺激功能的上下文控制。实验 2 添加了第三个背景，其中没有程序化反应得到强化，即，反应消失了。功能转移测试揭示了三种不同功能的上下文控制，包括衍生消光。讨论了等价关系作为符号功能的行为分析模型的含义。
