These correspond to the statistical maps shown in Fig. 2, Right. The input to the between-group contrast was the statistical maps shown in Fig. 1 and Table S2, in other words with activation in the backward-layered control condition subtracted and masked with the contrasts of the language condition with fixation baseline. Note that deaf signers only showed greater activation than nonsigners for ASL, whereas hearing nonsigners only showed greater activation than deaf signers for gesture. Details of table creation are as for Table S1.
