assuming I didn't screw up loading:

Counter-balance table for orders up to 2:
Targets/Order O1                 |  O2               |
    angry:     0 16  3  1  2  2  |   2  8 5  4 3  2  |
  baseline:   17  1 16 13 20 12  |   7 37 8 10 4 12  |
    fear:      2 17  0  1  0  4  |   2  8 2  3 6  3  |
    happy:     1 17  1  1  2  2  |   4  7 3  2 3  5  |
   neutral:    3 14  0  4  0  3  |   2 10 4  1 6  1  |
     sad:      1 15  4  3  0  1  |   7  9 2  3 2  1  |
Correlations: min=-0.2 max=0.16 mean=-0.005 sum(abs)=13
