Learning with explicit or implicit feedback on which factor was rewarded. (a) Error level in the baseline phase and in the third learning phase for the Slant First group and for the Slant First Implicit group. Thin lines connect for individual participants the error level in the baseline (left) and in the third learning phase (right). Thick lines represent the median for each group. (b) Learning of the multidimensional task in the third learning phase. Dots represent individual participants and the black line represents the median across participants. (c) Learning of the slant factor and length factor in the first learning phase. Dots represent individual participants and the black line represents the median across participants. For each participant, the horizontal position of the data is the same across all panels.
