Behavioral perspectives on the neuroscience of drug addiction.
Addiction is learned behavior, and delay-discounting tasks give BCBAs a ready ruler for measuring drug reinforcing strength.
01Research in Context
What this study did
Winger et al. (2005) wrote a theory paper. They said addiction is learned behavior. Drugs act like any other reinforcer. The brain disease story hides the learning part.
The authors asked behavior analysts to build new tools. These tools would measure how strongly drugs pull behavior. No new data were collected.
What they found
The paper did not test people. It argued that addiction science needs better behavioral yardsticks. Without them, treatment drifts toward biology-only fixes.
How this fits with other research
MacKillop (2013) answered the call. The review showed that delay discounting is a stable, heritable marker. It gives the field a ready-made yardstick for drug reinforcing strength.
Rung et al. (2019) went further. They showed that discounting can be changed with behavioral tricks. This turns the target’s static model into a treatment target.
Green et al. (2019) add nuance. Steep discounting is not a fixed trait. Context shapes choice. This keeps the behavioral frame but warns against labeling clients as simply impulsive.
Why it matters
You now have a clear path. Start measuring delay discounting in clients with substance use. Use brief adjusting-amount tasks. Track how impulsive choice moves as treatment proceeds. Pair the data with contingency management. You will be testing the very model Gail et al. asked the field to build.

03Original abstract
Neuroscientific approaches to drug addiction traditionally have been based on the premise that addiction is a process that results from brain changes that in turn result from chronic administration of drugs of abuse. An alternative approach views drug addiction as a behavioral disorder in which drugs function as preeminent reinforcers. Although there is a fundamental discrepancy between these two approaches, the emerging neuroscience of reinforcement and choice behavior eventually may shed light on the brain mechanisms involved in excessive drug use. Behavioral scientists could assist in this understanding by devoting more attention to the assessment of differences in the reinforcing strength of drugs and by attempting to develop and validate behavioral models of addiction.
