p Values are corrected for multiple comparisons, considering the areas that activated both for selection of two positions (cf. Table 1A) and selection of two categories (cf. Table 1B). On the right side of the table, we report coordinates and statistical scores of an additional analysis that considered reaction times (RTs) as a covariate of no interest. n.v.i. = not in the search volume of interest.
