In treatments for alcohol dependence, when patients drink alcohol mixed with a substance that induces nausea, which therapeutic method is being applied?

Explanation

The technique described is aversive therapy, where an unpleasant stimulus (nausea-inducing drug) is paired with the undesired behavior (alcohol consumption) to reduce the behavior. This differs from free association (exploring thoughts), systematic desensitization (reducing fear through gradual exposure), and operant conditioning (modifying behavior via rewards or punishments).
