(A) Sequential congruency effect from Fischer et al. (2008). On the X-axis, small letters (c, i) indicate previous-trial congruency; capital letters (C, I) indicate current-trial congruency. (B) Simulated sequential congruency effect. (C) Simulated accuracy across different levels of reward and task difficulty. (D) Simulated accuracy across different levels of learning rate and cost. (E) Simulated congruency effect across reward and task difficulty. (F) Simulated congruency effect across learning rate and cost. (G) Simulated sequential congruency effect across reward and task difficulty. (H) Simulated sequential congruency effect across learning rate and cost. Black dots in (C–H) indicate the parameter used to generate (B).
