Correction to: Translational Psychiatry https://doi.org/10.1038/s41398-020-01162-0, published online 07 January 2021

The original version of this article unfortunately contained an error. The authors state that in the original article they described in the first sub-section of Results (in lines 207–209) that “An estimated Bayes factor from the Bayesian t test (BF01 = 1.463) suggested that it was 1.067 times more likely there was no genotype difference of learning rate than there was genotype difference (see Fig. 2C).” The BF01 = 1.463 is a mistake. It should be revised to BF01 = 1.067 that “An estimated Bayes factor from the Bayesian t test (BF01 = 1.067) suggested that it was 1.067 times more likely there was no genotype difference of learning rate than there was genotype difference (see Fig. 2C).” In addition, in the original file of Fig. 2B, the vertical gapped lines for KO group were accidentally placed in the wrong position when aligning the whole figure 2. The authors apologize for the errors. The original article has been corrected.
