Objective: Impaired habituation of bodily sensations has been suggested as a contributing factor to chronic pain. We examined in healthy volunteers the influence of fear learning toward a nonpainful sensation in the esophagus on the perceptual habituation of this sensation.
Methods: In a homoreflexive fear learning paradigm, nonpainful electrical sensations in the esophagus were used as a conditioned stimulus (CS).
Avoidance behavior constitutes a major transdiagnostic symptom that exacerbates anxiety. It hampers fear extinction and predicts poor therapy-outcome. Pavlovian counterconditioning with a reward could alleviate avoidance better than traditional extinction by reducing negative valence of the feared situation.

In this study, we developed and validated an instrument assessing IBD-related, modifiable behaviours and explored which behaviours prospectively correlate with fatigue, a debilitating and common symptom in IBD.
Methods: Initially, 72 items reflecting IBD-related behaviours were generated based on literature review and input from clinicians and people diagnosed with IBD.
Objectives: Worry is the most common psychological complaint among patients with Inflammatory Bowel Disease (IBD). This study aimed to translate and test the psychometric properties the Rating Form of IBD Patient Concerns (RFIPC) among Dutch-speaking patients with IBD in Belgium. It also aimed to describe worries and concerns, and to examine possible differences in worry patterns between patients with different disease types and disease activities.

- Stressors trigger physiological changes that prepare the body for defensive responses, but most research focuses on negative effects of psychological stress in lab settings.
- In a study of 126 participants at a music festival, it was found that voluntary stage performance significantly raised cortisol levels and heart rates, while positively affecting emotional states by reducing negative feelings and increasing positive ones.
- Despite the positive emotional response, heightened stress during performance negatively impacted working memory performance, linking increased cortisol to slower reaction times, suggesting a need for more research on real-life stressors and their mixed effects.
