From: Hydrocortisone decreases metacognitive efficiency independent of perceived stress
Comparison between Placebo and Hydrocortisone groups. The different panels represent (A1) cortisol concentration in saliva samples (power transformed40), (A2) perceived stress (as measured by the STAI-S), (B1) stimulus contrast, (B2) response times (in seconds), (C1) the metacognitive efficiency in the perceptual task (md-Ratio), (C2) type 1 sensitivity in the perceptual task (in d’ units), (D1) mean confidence (on a half-scale from .5 to 1) and (D2) confidence estimates in a serial dependency analysis. On each panel, dots and error bars represent the mean and standard error across participants, separately for Placebo group (in blue) and the Hydrocortisone group (in red). Labels (C0–C6) correspond to the cortisol samples, with (C0) being the baseline. Labels (B1–B5) correspond to the experimental blocks.
