[open] Blocks Randomisation
I am planning an experiment with 6 blocks, each of them includes a learning phase (20 trials) and a testing phase (40 trials). I need little help to know how to randomise the order in which each of the sequences will be presented. The attached picture shows the possible structure I would like to have.
Thanks in advance,
