Participants

Forty-two healthy participants with normal to corrected to normal vision completed the experiment (10 males; mean age = 24.9; age range = 18-34 years). They were paid 16€ for 2 hours of participation and earned an additional performance bonus (mean = 10.2€, SD = 1.8). The ethical committee of the Vrije Universiteit Amsterdam approved the study and written informed consent was obtained from all participants. Eight participants were excluded from analyses due to the following reasons: inadequate fixation to the center of the screen (N = 4), reporting more than three unique stimulus pairs in the learning phase (N = 1) and (almost) perfect choice accuracy in the learning phase, which complicated behavioral model fitting (N = 3), resulting in a total of 34 participants for the analyses.
