Effect of predictors on EEfRT decisions after the logistic mixed model. (A) Participants tended to choose the effortful alternative when money increased, but strongly depending on trial probability. Note that effortful choices for low probability trials (12%) were always below 0.5 irrespective of the money at stake, whereas they were above 0.7 in high probability trials, even for small rewards. (B) The effect of fatigue is apparent for all trial types: chances to select the effortful alternative decreased with trial number in all cases. (C) The probability of choosing the effortful alternative with respect to trial probability followed a nearly sigmoid shape for undiagnosed participants and medicated ADHD volunteers. However, the curve was less steep for medicated participants, whose preference for the effortful alternative was higher than the other groups in low-probability trials but similar to them in high-probability trials.
