Conscious effort manipulation. A: Wv of a subject who was told explicitly to aim for the P component of VP targets in Block 1 and the V component in Block 2 and was therefore predicted to up-weight vision between blocks. Error bars represent SD. B: trial-by-trial Wv averaged across subjects who were told to aim for the P component in Block 1 and the V component in Block 2 and thus predicted to up-weight between blocks (gray dashed line) or who performed the blocks in the reverse order and were predicted to down-weight between blocks (black line). Error bars represent standard error. C: group difference in Wv between Blocks 1 and 2, normalized to Block 1 Subjects were able to change weightings consciously, especially when trying to up-weight vision. Ctrl = control group. Dark gray bar: aiming for V in Block 1. Light gray bar: aiming for P in Block 1. Arrows: predicted direction of reweighting. Asterisk: significantly different from both other groups.
