Fig. 4: Between-task comparisons of overall performance.

The data are shown for (a) type-1 accuracy (d'), (b) metacognitive sensitivity (meta-dā), (c) metacognitive efficiency (meta-dā/dā), (d) criterion (type-1 cā) and (e) type-2 criterion (confidence c'). On each box, the central line is the median, the edges of the box are the 25th and 75th percentiles, and the whiskers extend ±2.7 standard deviations from the median. *Pā<ā0.05, **Pā<ā0.01.
