A check mark indicates that a regressor is part of the model. A check mark with an asterisk indicates that this regressor is only present in models that include error trials. A check mark in parentheses indicates that the predictor was included only if it had a p values of <0.4 in the full model. An asterisk between to predictors indicates that both predictors as well as their interaction was included in the model.
