Randomise stimuli without consecutive presentation

[JensBoelte]

Hello you330,

you need some code to do this.

Randomisation with constraints

@JensBoelte Sorry for not being clear. Let’s start from the beginning. (unfortunately, I cannot share the exp because of unpleasant stimuli). [image] LEARN 1: participants learn associations between sounds (24) and shapes (48). Each sound is paired with 2 different shapes. (e.g. Trial1: sound A – shape 1 / Trial2: sound A – shape 2 …… Trial47: sound 24 – shape 47 / Trial48: sound 24 – shape 48). MULTIPLEC_1: participants are tested on the learnt associations. I have 48 trials in which partic…

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…

These should give you the relevant information.

Best wishes Jens
