To randomly transfer half of the items from one block_loop to another
I have a sequence of three blocks in my experiment. Block 2 follows Block 1 and contains 18 items (videos). I already have this programmed. Now I want, at the beginning of the experiment, the program to randomly pick half of the 18 items from block 2 and put it into block 1 where the items should also be presented randomized.
Block 1 has 34 items and Block 2 has 18 items. The participant should always be presented 42 Items in Block 1 (34 of original block 1 and 9 from block 2) and 9 in Block 2 (the remaining 9).
I've got the feeling this will only be possible with some Python Inline Script, I hope someone can help.
