Biased visceral perception through fear learning Biased intensity judgements of visceral sensations after learning to fear visceral stimuli: a drift diffusion approach

A growing body of research has identified fear of visceral sensations as a potential mechanism in the development and maintenance of visceral pain disorders. However, the extent to which such learned fear affects visceroception remains unclear. To address this question, we used a differential fear conditioning paradigm with non-painful esophageal balloon distensions of two different intensities as conditioning stimuli (CSs). The experiment comprised pre-acquisition, acquisition and post-acquisition phases during which participants categorized the CSs with respect to their intensity.
