Paul Sharp, the lead author, noticed two errors in the naming of variables in two the key equations in the article.

Equation 6 is incorrect. The equation in the published article read::

(6) $\begin{array}{l}\left[\begin{array}{l}{Q}_{M{B}_{t+1}}\left(press=g\right)\\ {Q}_{M{B}_{t+1}}\left(press=j\right)\end{array}\right]\\ =\left[\begin{array}{ll}{\beta }_{MBreward}P\left(f=reward|press=g{\right)}_{t}& {\beta }_{MBpunish}P\left(f=punish|press=g{\right)}_{t}\\ {\beta }_{MBreward}P\left(f=reward|press=j{\right)}_{t}& {\beta }_{MBpunish}P\left(f=punish|press=j{\right)}_{t}\end{array}\right]\left[\begin{array}{c}0\\ -1\end{array}\right]\end{array}$

The correction to equation (6) is as follows:

(6) $\begin{array}{l}\left[\begin{array}{l}{Q}_{G{P}_{t+1}}\left(press=g\right)\\ {Q}_{G{P}_{t+1}}\left(press=j\right)\end{array}\right]\\ =\left[\begin{array}{ll}{\beta }_{GPreward}P\left(f=reward|a=press\phantom{\rule{thinmathspace}{0ex}}g{\right)}_{t}& {\beta }_{GPpunish}P\left(f=punish|a=press\phantom{\rule{thinmathspace}{0ex}}g{\right)}_{t}\\ {\beta }_{GPreward}P\left(f=reward|a=press\phantom{\rule{thinmathspace}{0ex}}j{\right)}_{t}& {\beta }_{GPpunish}P\left(f=punish|a=press\phantom{\rule{thinmathspace}{0ex}}j{\right)}_{t}\end{array}\right]\end{array}$

Equation 8 also also had a slight error in how the action variable was named. It is now consistent with how all other equations reflect the action taken. The original equation in the article was:

(8)

The equation is now correction to read:

(8)

We apologize for any confusion this might have caused.
