nearly significantp = 0.0516
Post hoc cluster tests within each task revealed a matching, nearly significant cluster of increased activity in the IPS during two-numeral compared to one-numeral trials in the addition task from 131 to 209 ms, p = 0.0516 (10,000) and found no significant differences within the list task at any point (all clusters p > 0.70; 10,000 permutations).
