Fig. 6. A: Reaction time distribution as a function of Status (sham-AI vs. no-AI) and Description (incorrect
trials are multiplied with -1). B: Posterior density plot for the parameter values for all population-level
parameters 95% HDI. If the HDI does not cross the midline, 𝑝𝑏 will be <2.5%.

Inspecting the RT of correct trials as a function of Status, we can see that RT distribution are
slightly different, see Figure 6A, with sham-AI producing faster RTs for correct trials as compared
to no-AI. This is also reflected in the mean of the distributions, see Table 2.
