Abstract
The ability to predict the consequences of our actions is imperative for the everyday success of our interactions. From negotiating an uneven surface, to mounting an immune response, we continually infer the limits of our body. The current investigation considered the impact that the inferred consequences of action has on the placement of limits. We hypothesised that the performance of individuals in a novel, sprint task would reflect both their ability to accurately detect changes in bodily arousal (Interoceptive Accuracy) and the inferred consequences associated with heightened arousal signals (Anxiety Sensitivity). We found that individuals who demonstrated accuracy associated with physiological arousal changes, and who showed a heightened fear of the consequences of arousal symptoms, modified their actions by decreasing their power output (mean Watts•kg-1) in a sprint task (ΔR2 = 0.19; F(1,34) = 19.87); p<0.001). These findings provide a basis for understanding the varying actions taken as we encounter bodily perturbation.
Highlights
As we negotiate our environment, we are continually required to disambiguate noisy and uncertain information [1]
Sensing changes specific to the body is known as interoception, and it is comprised of 3 dimensions: Interoceptive accuracy- objective performance in detection; Interoceptive sensibility- self-evaluated assessment of interoception; Interoceptive awareness- metacognitive appraisal of accuracy [4]
We explored to what extent Interoceptive Accuracy related to potential confound variables
Summary
As we negotiate our environment, we are continually required to disambiguate noisy and uncertain information [1]. The actions of our body, and the continual predictions of the consequences of these actions, help us to make sense of a changing world [2]. We are able to actively filter information and flexibly update our predictions as our body and the environment change [3]. Sensing changes specific to the body is known as interoception, and it is comprised of 3 dimensions: Interoceptive accuracy- objective performance in detection; Interoceptive sensibility- self-evaluated assessment of interoception; Interoceptive awareness- metacognitive appraisal of accuracy [4]. It has been proposed that the ability to precisely detect changes in our body—Interoceptive Accuracy—promotes flexible updating of the predictions of our body and allows for a more fine-tuned regulation of behaviour [5,6,7,8,9].
