Appendix 1—figure 8. Reanalysis of Moran et al., 2019, based on the current models.

(A–F) As Appendix 1—figure 7 but for the data of Moran et al., 2019. Each of the sub-models was rejected at the group level in favour of the full model. (G) Full-model uncertainty trials model-based credit assignment (MFCA) parameters as a function of outcome informativeness (blue/red) and nomination. Using a mixed effects model, we found a significant interaction effect between informativeness and nomination (b = 0.10, t = 2.05, p = 0.042) implying the nomination effect on MFCA was stronger for the informative than the non-informative outcome. Simple effect analysis showed significant positive nomination effects for both the informative outcome (blue; b = 0.2, F(1,156) = 28.16, p = 4e-7) and the non-informative outcome (red; b = 0.31, F(1,156) = 12.36, p = 6e-4). Thus, this analysis supports the conclusions from Moran et al., 2019, that retrospective model-based (MB) inference guides MFCA on uncertainty trials for both outcomes. Note that Moran et al., 2019, did not separate MFCA for the informative and non-informative outcomes.
