AB In the present experiment, we assessed the relationship between intolerance of uncertainty and expectancy ratings of threats both in the presence of conditioned stimuli (CS) that signalled the delivery of an aversive unconditioned stimulus (US), and after making an avoidance response. Participants learned the relationship between several pictures serving as CSs and an aversive sound serving as the US, and learned to avoid the US through a procedure including alternating pavlovian and negative reinforcement training phases. Expectancy ratings were measured on every training trial. Our results only showed a significantassociation between intolerance of uncertainty and expectancy ratings made after avoidance responses. This association was found only when the avoidance response was made in the presence of CSs signalling that the aversive sound was avoidable. The increase in intolerance of uncertainty was related to lower expectancy ratings in good learners, and to higher expectancy ratings in bad learners. These results are tentatively explained by invoking a view of intolerance of uncertainty as an exaggerated reaction to uncertainty aimed at learning to avoid threats.
