Abstract

The framework for addiction offered by the target article can perhaps be simplified into fewer, more basic, vulnerabilities. “Impulsivity” covers a number of vulnerabilities, not just enhanced delay discounting. Real-world drug-use decisions involve both delay and probability discounting. The motivational salience of, and attentional bias for, drug cues may be related to a number of vulnerabilities. Interactions among vulnerabilities are of significance and complicate the application of this framework.
