A scene to begin with

In one setting, a drug-related cue overwhelms every alternative; in another, the same person can pause and choose. The model asks how salience and inhibitory control interact with context—and why recovery must remain part of the picture.

The question underneath

Addiction research asks how salience, inhibition and context shape a choice—and why recovery has to remain in the frame.

What changes when we look closer

The model treats addiction as an interaction between cue, context and cognitive function rather than a simple failure of will.

01

Salience and control interact

The iRISA model proposes that drug-related cues acquire disproportionate motivational value while inhibitory control becomes less effective, especially in drug-related contexts. These are linked processes rather than two independent deficits. A cue that captures attention, memory and expected reward creates a harder control problem; reduced control then permits the cue to dominate behavior more fully.

02

The model includes heterogeneity and recovery

Neuroimaging evidence implicates prefrontal and salience-related systems, but the review does not present one permanent brain signature shared by everyone. Substance, stage, context and individual history matter. Metacognitive difficulties may also affect awareness of choice. Evidence of functional recovery is therefore central: the model describes dynamic processes that can change, not a moral failure or an irreversible identity.

03

The concepts that make the explanation work

Salience attribution. The process of assigning importance and motivational value to a cue. A drug-related cue captures attention over alternative rewards. It explains why some cues gain disproportionate control over behavior.

04

How the conclusions fit together

The review does not offer three independent facts. Its conclusions form a sequence: the first reframes the phenomenon, the second identifies an important condition or process, and the third shows what changes when that explanation is used.

  1. 01

    Drug cues can dominate salience.

  2. 02

    Inhibition depends on context.

  3. 03

    Recovery is an essential part of the evidence.

These ideas must retain this limit: Brain differences are heterogeneous and should not be interpreted as permanent damage in every individual.

What to keep

  1. Drug cues can dominate salience.
  2. Inhibition depends on context.
  3. Recovery is an essential part of the evidence.
  4. Salience attribution: The process of assigning importance and motivational value to a cue.
  5. Brain differences are heterogeneous and should not be interpreted as permanent damage in every individual.
