Hi I am wondering whether it is possible to counterbalance the order of blocks in an IAT. I need for Blocks 1, 3, and 4 to swap with blocks 5, 6, 7 (i.e. participants either recieve block 1, 2, 3, 4, 5, 6, 7, or blocks 5, 2, 6, 7, 1, 3, 4, in this order). Between each block is an instruction page that needs to stay in place regardless of the order. I am actually conducting three IAT's and would like these randomly presented to participants. I haven't been able to figure out a way to present the three IAT's in random order - and within each IAT, have random alocation to one of the two block orderings.
