Renewal, resurgence, and alternative reinforcement context

Area of Science:

• Behavioral Psychology
• Operant Conditioning
• Relapse Phenomena

Background:

• Resurgence and renewal are typically studied independently in operant conditioning.
• These relapse phenomena can occur simultaneously in problem behavior treatments.
• A unified experimental approach is needed to understand their interaction.

Purpose of the Study:

• To develop and evaluate a novel experimental preparation for studying resurgence and renewal together.
• To investigate how combined resurgence and renewal paradigms affect relapse.
• To explore the influence of alternative reinforcement context on relapse persistence.

Main Methods:

• Rats were exposed to extinction with or without alternative reinforcement.
• One group experienced extinction in a familiar context (resurgence preparation).
• Another group experienced extinction in a novel context (renewal preparation).
• A third group combined alternative reinforcement with a novel extinction context.

Main Results:

• Both removal of alternative reinforcement and context change induced relapse compared to controls.
• Alternative reinforcement in a novel context reduced response persistence compared to training context.
• The combined preparation demonstrated interactions between resurgence and renewal effects.

Conclusions:

• The novel methodology effectively integrates resurgence and renewal paradigms.
• Contextual changes and alternative reinforcement interact to influence relapse.
• This approach can elucidate shared or distinct mechanisms underlying relapse and inform behavioral interventions.
