Andrew,

Great - you've confirmed exactly what I wanted to know (directionality).

Thanks again - much appreciated!

Hi Lee,

These tests are already specific for each of the EVs (main & interactions). The only post-hoc tests I believe you might want is to see the direction of the effects (positive or negative) that appeared in the F-tests. For this, you can add 7 new contrasts that are the same as those that you already have, but replacing the 1 for -1 in each of them. You can then drop the F-tests.

All the best,

Anderson

Thanks for your response.

Of course, please find attached my model (for 20 participants).

Contrasts were as follows:

                   EV1      EV2   EV3   EV4   EV5  EV6   EV7 EV8-EV27       F1 F2 F3 F4 F5 F6 F7
A                  1           0       0       0       0     0         0       0                X
B                  0           1       0       0       0     0         0       0                    X
C                  0           0       1      0       0      0         0        0                       X
AB                0           0        0     1       0      0         0        0                            X

AC                0           0        0     0       0      1        0        0                                      X
