Distribution of \(\Delta G^2\) values, obtained from the comparison of the SDT\(_{\tau 4,\,\emptyset }\) and SDT\(_{\tau 4,\,\mu 1}\) models, when generating the confidence rating data from the latter under different values of \(\alpha _{2-6}\). Two-hundred datasets were generated per scenario. The black circle corresponds to the \(\Delta G^2 = 0.01\) observed with the real data (see Table 3). The red lines correspond to polynomial spline approximations of the \(\Delta G^2\) distributions. Please note that the ranges of both axes vary across panels
