Blushing-fearful individuals overestimate the costs and probability of their blushing.

It has been proposed that blushing-fearful individuals overestimate both the probability and the interpersonal costs of blushing. To study these judgmental biases, we presented a treatment-seeking sample of blushing-fearful individuals a series of vignettes describing social events and tested whether this clinical sample would overestimate the costs and probability of blushing compared to non-fearful controls. To test if blushing-fearfuls overestimate and/or low-fearful individuals underestimate the cost of displaying a blush, a second experiment examined the effects of blushing in these situations on observers' judgments. Experiment 1 showed that blushing-fearfuls indeed have judgmental biases for the probability and costs of blushing. Experiment 2 showed that the observers' judgments were very similar to the judgments anticipated by the low-fear group in Experiment 1. Thus the judgmental biases that were evident in the high-fearfuls can be best interpreted as an overestimation of the social costs of displaying a blush. These findings help improving our understanding of the mechanisms that may drive blushing phobia and also point to the clinical implication that it might be worthwhile to challenge blushing-fearfuls' judgmental biases.
