Searchlight-defined ROIs encoding task set. We combined a roving searchlight analysis with an SVM to identify cortical regions representing participants' task set (i.e., attend orientation vs attend luminance; p < 0.01, FDR corrected for multiple comparisons). Here, the resulting map has been projected onto a computationally inflated image of a representative participant's brain (DM). For exposition, searchlight neighborhoods containing a robust representation of orientation have been assigned a value of 1 while neighborhoods that did not have been zeroed out. From this map, we manually defined a set of 19 frontal, parietal, and inferior temporal ROIs that encoded task set (Table 2).
