  1. Conditions of interest, equal alternatives, always had the same probability of being presented on screen, across sessions (accuracy versus value) and overall reward received (high versus low). In particular, each pair of equal alternatives (e.g., 12 versus 12 dots, 18 versus 18 dots etc) had a probability of .04 of being presented, for a total of 20% of equal alternatives presented during the experiment
