to get Certainty effects before the initial choice, as we have seen previously (e.g. Grogan et al., 2023).
No model could replicate a surprising result; that the CPP was larger when speed-pressure (short deadline) was applied to the confidence-ratings, suggesting additional mechanisms at play...

Boundary-Single models could replicate the effects of Certainty we saw on the CPP, while Boundary-Distinct could not, especially for pre-choice effects.
Having pre- and post-choice as a Single process allows evidence-info to carry over and inform certainty ratings, which seems to be necessary...

there was little difference between Boundary models where the pre- and post-decision accumulation processes were Distinct or a Single process, when looking at behavioural fits.
However, simulating Decision-Variable accumulation traces allowed us to compare these different mechanisms directly...

on a task with long or short post-decision deadlines to rate confidence, which induced a post-decision/confidence speed-accuracy trade-off.
Post-decision accumulation was better explained by accumulation to collapsing confidence-boundaries, than by a Time-based stopping rule, but...
