Hello, I have a question about the selection of blocks. I have a total of four blocks that I would like to be randomly selected each time a participant starts the experiment. However, block 1 is a practice version of block 2, so I would like these two blocks to always proceed in sequential order. Is there a way to do this? Thus, when the experiment begins, Inquisit would essentially randomly select from blocks 1, 3, and 4. Whenever block 1 is selected, then it would automatically proceed to block 2, and then randomly select the remaining blocks, etc. Any thoughts on this matter would be greatly appreciated. The only thing I could come up with is maybe creating a list of the blocks and selecting from this during the expt (experiment) section, but I am unclear how to do this. Thanks in advance.
