Activations for numbers > object names (number selectivity) for conceptual tasks only, conceptual > perceptual judgments, quantity and nonquantity judgments only in Analysis 1 (RTs modeled separately for numbers and object names) and for conceptual tasks only in Analysis 2 (RTs modeled over number and object names).

Values in bold indicate significance at p < .05, corrected for multiple comparisons.

H = hemisphere; L = left; R = right.

aWithin 4 mm.
