files… but I can’t do it for $stimuli as these values & their number is fixed. I can get around repetition in $piano by creating 30 unique wav. It doesn’t matter what value from $piano is combined with what value from $stimuli as long as neither of these values featured in the preceding trial. Some of them have also been repeated consecutively. Not a lot (one or two items are repeated consecutively) but it’s still there… Also note the 2nd column of my stimuli set $piano containing 10x wav files. …in Begin Experiment there is still repetition. ThisStimulus = (thisStimulus+randint(1,10))%10 ThisStimulus = (thisStimulus+randint(1,9))%10 Would anyone have any idea as to how to get around this problem?Īlso, I need to be able to run this on Pavlovia, but for now getting it working in the builder would be great. When I run it in the builder the 3 letter combinations aren’t showing. The revised sheet linked to the loop has 3 columns only (piano, corrAns, picture). I also created a revised excel sheet where I took out the column containing these 3 letter combinations so as not to confuse the builder. Stimulus_list = *# I have adjusted the values to those in my stimuli sheet. List_ok = True # Yay! The loop won’t run again. Shuffle(stimulus_list) make sure the same target doesn’t appear on consecutive trials This is the code I got from another post (by kmcdubb) same stimuli is still likely to feature twice in a row. I have tried inserting a code element at the beginning of the loop and top of the routine but info in the loop prevails i.e. TRIAL 1: text stimuli ‘ijb’ & sound/a.wav TRIAL 2: text stimuli ‘abz’ & sound/d.wav TRIAL 3: can’t include either text stimuli ‘abz’ or sound/d.wav) I have used the ‘randomize’ function within the builder which is fine but I would like to ensure that no one set of letters or sounds features in consecutive trials (i.e. of text stimuli), correct answers (in response to sound stimuli), and a jpg of a piano key (30x) which is to be displayed at all times. text stimuli (x 30 unique 3-letter-long combinations), sound stimuli (10 varieties input 3x to match no. I have created an excel sheet which contains all the values i.e. Must indicate which sound is the odd one out by clicking either ‘z’ or ‘m’.Hear 3 sounds and must decide which sound is the odd one out.I have designed an experiment (using the builder) where in a single trial participants are simultaneously presented with audio stimuli and text stimuli. Hello, I’m new to PsychoPy & in need of assistance.
