Reinforcement of competing behavior during extinction

Area of Science:

• Behavioral psychology
• Animal learning theory
• Neuroscience of learning and memory

Background:

• Conditioned behaviors typically decrease when reinforcement is removed.
• Extinction is a fundamental process in understanding behavioral change.
• The role of competing behaviors in modulating extinction is not fully understood.

Purpose of the Study:

• To investigate whether reinforcing competing behaviors facilitates the extinction of a primary conditioned response.
• To determine if this facilitation leads to overall savings in the extinction process.

Main Methods:

• Two experiments were conducted using rats as subjects.
• Conditioned behavior was extinguished while simultaneously reinforcing competing behaviors.
• Reinforcement for competing behaviors was subsequently withdrawn to assess behavioral retention.

Main Results:

• Reinforcing competing behaviors significantly accelerated the extinction of the original conditioned response.
• Upon withdrawal of reinforcement for competing behaviors, rats resumed their original behavior.
• No overall savings in the total number of responses required for extinction were observed.

Conclusions:

• Competing behavior reinforcement can be an effective strategy to expedite behavioral extinction.
• The effects of competing behavior reinforcement are transient, with original behaviors resurfacing upon cessation of competing reinforcement.
• This suggests that extinction facilitated by competing behaviors does not confer lasting resistance to relapse.
