random selection of different sequences of primes within one block

Group: Forum Members Posts: 12, Visits: 39	Hi there, I am programming an experiment in which two different sequences of trials are presented within one block in random order (and different frequencies). Instead of this: /trials = [1-16 = sequence(fixtrial1, primetrial); 17-24 = sequence(fixtrial2, detection) which presents the first sequence of 2 trials 16 times and the second 8 times afterwards, I would like to actually do something like this: /trials = [1-24 = random(sequence(fixtrial1, primetrial), sequence(fixtrial1, primetrial), sequence(fixtrial2, detection); which obviously does not work. Meaning that 2/3 of trial sequences within the block should be sequence(fixtrial1, primetrial); randomly interspersed by 1/3 of the sequence (fixtrial2, detection). Is there an easy way to do this? As always, any help would be much appreciated! thanks, Juliane
