Supplementary Table 1. Post hoc pairwise comparisons on the six ROIs that showed a
main effect for condition (V1~V4, FFA, and OFA). Listed are the mean differences
and the associated p values (Bonforroni corrected). See main text pp. 13 and Figure 3
for details. There was an overall trend indicating that the percent signal changes were
CON<2FR<3FR<NRF; no ROI showed opposite results.

Supplementary Table 2. The loadings for each factor of the nine rating-correlated
ROIs, collapsed across 4 conditions. The time courses were extracted separately for
each block type, starting from 2 TRs before block onset and 13 TRs after onset to
capture the rising and falling of the signal over a block.

Supplementary Figures 1-4. Top: graphical representation of the correlation matrices
of the following ROIs: (1) visual areas, (2) medial frontal gryus, (3) right
superolateral frontal areas, (4) left superolateral frontal areas, (5)
precuneus-postcentral gyrus, (6) right insula, (7) right middle frontal gyrus, (8) left
middle frontal gyrus, (9) left superior temporal sulcus, collapsing across four
experimental conditions (CON, 2FR, 3FR, and NRF, respectively). Bottom: geometric
representation of the rotated factors. One can see that the nine ROIs could also be
visually categorized into three separate groups: the first (X1, X2, X3, and X4), the
second (X5, X6, and X9), and third (X7 and X8), except for the CON condition
(figure 1).
