so i just figured out (after 30 participants unfortunately), that my command for Blocks (get a different order for incompatible and compatible trials when putting in a 1 or 2 at the beginning of each test) doesnt work but rather assigns orders at random it seems.
this is very annoying since i now have to recode almost every subject for my IAT algorithm to work...
i have been using a syntax from a former colleqgue and just copy pasted some aspects so i am not totally sure where it is going wrong/what i should change. i am browsing the inquisit manuals but have not yet found the answer.
here the code where i believe the mistake might be hidden:
<expt>
/ subjects = (1 of 1)
/ preinstructions = (begin1)
/ postinstructions = (end)
/ blocks = [1=survey;
2=block1_bs;
3=attributepractice_bs;
4=block3_bs;
5=block4_bs;
6=block5_bs;
7=block6_bs;
8=block7_bs;
9=block8_bs;
10=block9_bs;
11=block1_Kommunikation;
12=attributepractice_Kommunikation;
13=block3_Kommunikation;
14=block4_Kommunikation;
15=block5_Kommunikation;
16=block6_Kommunikation;
17=block7_Kommunikation;
18=block8_Kommunikation;
19=block9_Kommunikation]
</expt>
<variables>
/ group = (1 of 2) (block1_bs=targetcompatiblepractice_bs;
block3_bs=compatibletest1_bs;
block4_bs=compatibletestinstructions_bs;
block5_bs=compatibletest2_bs;
block6_bs=targetincompatiblepractice_bs;
block7_bs=incompatibletest1_bs;
block8_bs=incompatibletestinstructions_bs;
block9_bs=incompatibletest2_bs;
block1_Kommunikation=targetcompatiblepractice_Kommunikation;
block3_Kommunikation=compatibletest1_Kommunikation;
block4_Kommunikation=compatibletestinstructions_Kommunikation;
block5_Kommunikation=compatibletest2_Kommunikation;
block6_Kommunikation=targetincompatiblepractice_Kommunikation;
block7_Kommunikation=incompatibletest1_Kommunikation;
block8_Kommunikation=incompatibletestinstructions_Kommunikation;
block9_Kommunikation=incompatibletest2_Kommunikation)
/ group = (2 of 2) (block1_bs=targetincompatiblepractice_bs;
block3_bs=incompatibletest1_bs;
block4_bs=incompatibletestinstructions_bs;
block5_bs=incompatibletest2_bs;
block6_bs=targetcompatiblepractice_bs;
block7_bs=compatibletest1_bs;
block8_bs=compatibletestinstructions_bs;
block9_bs=compatibletest2_bs;
block1_Kommunikation=targetincompatiblepractice_Kommunikation;
block3_Kommunikation=incompatibletest1_Kommunikation;
block4_Kommunikation=incompatibletestinstructions_Kommunikation;
block5_Kommunikation=incompatibletest2_Kommunikation;
block6_Kommunikation=targetcompatiblepractice_Kommunikation;
block7_Kommunikation=compatibletest1_Kommunikation;
block8_Kommunikation=compatibletestinstructions_Kommunikation;
block9_Kommunikation=compatibletest2_Kommunikation)
</variables>
anyone see the mistake and can help me?

#1: You don't need the /subjects attribute in the <expt> element. You can delete it.
#2: Your <variables> element assigns different block orders (compatible vs. incompatible first) based on the provided *subject number*. I.e., a participant with an *odd* subject number (1, 3, 5, ...) will receive the compatible blocks first, a participant with an *even* subject number (2, 4, 6, ...) will receive the incompatible blocks first.
If you want the assignment to be done based on the *group number*, you need to specify
<variables>
/ groupassignment = groupnumber
/ group = (1 of 2) (block1_bs=targetcompatiblepractice_bs;
block3_bs=compatibletest1_bs;
block4_bs=compatibletestinstructions_bs;
block5_bs=compatibletest2_bs;
block6_bs=targetincompatiblepractice_bs;
block7_bs=incompatibletest1_bs;
block8_bs=incompatibletestinstructions_bs;
block9_bs=incompatibletest2_bs;
block1_Kommunikation=targetcompatiblepractice_Kommunikation;
block3_Kommunikation=compatibletest1_Kommunikation;
block4_Kommunikation=compatibletestinstructions_Kommunikation;
block5_Kommunikation=compatibletest2_Kommunikation;
block6_Kommunikation=targetincompatiblepractice_Kommunikation;
block7_Kommunikation=incompatibletest1_Kommunikation;
block8_Kommunikation=incompatibletestinstructions_Kommunikation;
block9_Kommunikation=incompatibletest2_Kommunikation)
/ group = (2 of 2) (block1_bs=targetincompatiblepractice_bs;
block3_bs=incompatibletest1_bs;
block4_bs=incompatibletestinstructions_bs;
block5_bs=incompatibletest2_bs;
block6_bs=targetcompatiblepractice_bs;
block7_bs=compatibletest1_bs;
block8_bs=compatibletestinstructions_bs;
block9_bs=compatibletest2_bs;
block1_Kommunikation=targetincompatiblepractice_Kommunikation;
block3_Kommunikation=incompatibletest1_Kommunikation;
block4_Kommunikation=incompatibletestinstructions_Kommunikation;
block5_Kommunikation=incompatibletest2_Kommunikation;
block6_Kommunikation=targetcompatiblepractice_Kommunikation;
block7_Kommunikation=compatibletest1_Kommunikation;
block8_Kommunikation=compatibletestinstructions_Kommunikation;
block9_Kommunikation=compatibletest2_Kommunikation)
</variables>
