Equivalence relations and the contextual control of multiple derived stimulus functions

Area of Science:

• Behavior Analysis
• Cognitive Psychology
• Symbolic Functioning

Background:

• Contextual control is crucial for understanding how stimuli acquire multiple functions or symbols gain multiple meanings.
• Equivalence research provides a framework for studying complex stimulus relations and their behavioral implications.

Purpose of the Study:

• To investigate the contextual control of multiple derived stimulus functions.
• To examine how different contexts (background colors) influence the functions of stimuli within equivalence classes.

Main Methods:

• Two experiments were conducted involving the formation of equivalence classes.
• Stimuli within these classes were subjected to different reinforcement schedules (positive and negative) under specific contextual control (background colors).
• Transfer-of-function tests assessed the derived stimulus functions under varying contextual conditions, including extinction.

Main Results:

• Contextual control of multiple derived stimulus functions was demonstrated.
• The study successfully showed that different background colors could elicit distinct behavioral functions associated with the same stimuli.
• Derived extinction was also observed as a function under contextual control.

Conclusions:

• Equivalence relations serve as a viable behavior-analytical model for symbolic functioning.
• Context plays a significant role in determining the multiple functions that stimuli can acquire and express.
• These findings have implications for understanding complex human cognition and learning.
