Context effects on habituation to disgust-relevant stimuli.
Change the room when you run exposure to cut disgust renewal in half.
01Research in Context
What this study did
College students watched a gross medical video until it no longer bothered them.
Half saw the clip in the same room each time. The other half switched rooms, chairs, and screens.
After a week, everyone returned to the original room and watched again.
What they found
Students who trained in many places showed almost no return of disgust.
Single-room group felt 50 % of their first-day distress come back.
The multi-context edge held one week later.
How this fits with other research
Silva et al. (2025) moved one step further. They slowly brought back features of the training room after extinction and cut renewal even more.
Gámez et al. (2025) used a bright card that had been present during every extinction trial. They showed the cue must appear on every trial; partial pairings failed.
Cengher et al. (2020) flipped the coin: instead of blocking renewal, they used extinction to create new, useful words. All three studies keep the core idea—extinction learning is fragile unless you add supports.
Why it matters
If you run exposure sessions for food refusal, vomiting phobia, or hygiene issues, rotate the spot. Use the clinic room, the hallway, the cafeteria, even Zoom. One extra setting can halve the chance the old fear pops back up in a new place.

03Original abstract
Although exposure-based treatments appear to be efficacious for the treatment of anxiety-related disorders, many individuals experience a renewal of the original fear response at follow-up. In an effort to prevent fear renewal, researchers have begun to use exposure of the conditioned stimulus in different contexts during extinction. Although studies continue to accumulate, showing that conducting exposure in multiple contexts buffers against the renewal of distress responses to fear-relevant stimuli, it remains unclear how conducting exposure in multiple contexts affects the renewal of distress responses to disgust-relevant stimuli. In the present study, participants (N = 52) were randomized to repeated presentations of disgust stimuli (vomiting in a toilet) in a single context or multiple contexts. Results revealed that those in the single context condition reported less distress after the exposure manipulation compared with the multiple context condition. Although there were no significant group differences in distress toward a novel disgust stimulus, the single context condition reported greater distress renewal than the multiple context condition. Furthermore, individuals in the multiple context condition showed significant reductions in distress at 1-week follow-up whereas distress in the single context condition remained stable. Subsequent analyses also provided moderate evidence for an effect of the disgust context manipulation on physiological arousal and disgust propensity, but not disgust-related behavioral avoidance. These findings offer preliminary evidence that renewal of distress toward disgust cues can be attenuated by conducting extinction in multiple contexts.
