Measures of local metacognition
| Group | Perception | Memory | ||||
|---|---|---|---|---|---|---|
| n | d’a | M-ratiob (HDI) | n | d’a | M-ratiob (HDI) | |
| FCD | 14c | 1.26 (0.40) | 0.62 [0.39, 0.87] | 18 | 1.03 (0.19) | 1.31 (1.08, 1.56) |
| Controls 1 | 42 | 1.33 (0.23) | 0.56 [0.43, 0.69] | 54 | 1.14 (0.21) | 1.13 (1.00, 1.26) |
| Controls 2 | 24 | 1.13 (0.35) | 0.66 [0.51, 0.82] | 24 | 1.12 (0.40) | 1.36 (1.17, 1.58) |
FCD, functional cognitive disorder; HDI, 95% highest density interval of sampled M-ratios.
a
d’, a metric of objective task performance per participant: mean (SD).
b
Metacognitive efficiency, calculated as meta-d’/d’: mean (SD) of sampled group parameters.
c
n = 14 because four participants were unable to complete an adequate number of perception trials.
