Hello,

this question has been asked before. Look here

Hello you330, you need some code to do this. These should give you the relevant information. Best wishes Jens

Randomisation without consecutive presentations

@Mirjam provides a general solution here: In your specific case, something like this might work: Insert a code component on your trial routine (from the “Custom” component panel). In its “begin experiment” tab, put something like this ( we need to run this at the start of the experiment since the code is non-deterministic: we don’t know how long it will take to run (realistically though, it will be a fraction of a second for only 12 entries): stimulus_list = ['v', 'b', 'n', 'm'] * 3 shuffl…
