Metacognitive impairments in high compulsives. (A) Group posterior of metacognitive efficiency (M-ratio) for high and low compulsive participants revealed that high compulsive participants are significantly worse in their metacognitive abilities (B). This is not due to perceptual differences, because we controlled for performance, also indicated by the absence of a difference in the perceptual performance (d’, C). (D) An illustration of the individual metacognitive efficiencies (diamonds) reveals that all but three participants from the high compulsive group perform worse than the low compulsives. There were no systematic biases in the accuracy (triangles) across the groups which highlights that metacognitive biases are not driven by perceptual difficulty. However, it must be noted that the metacognitive efficiencies depicted here are derived from a hierarchical model, and can thus not easily be interpreted or compared individually (i.e., they are not statistically independent). Bar plots: mean ± s.e.m.; n.s. p > 0.10.
