Figure 1. (A) One training trial in the probabilistic selection task Figure 1. (A) One training trial in the probabilistic selection task. Participants had 1 s to select one of the symbols presented to the left or to the right. Based on the selected symbol's reward probability, positive or negative feedback was presented. RT = response time. (B) Reward probabilities associated with each symbol. The reward probabilities and symbols were randomized between participants. (C) One trial in the lexical decision task. After fixation a prime (word or nonword) was presented centrally for 200 ms directly followed by a 150 ms presentation of either a laterally presented target (word or nonword). Participants indicated whether the target was a real word or a nonword. LVF = Left visual field. RVF = Right visual field.
