I’m trying to put together a pilot study in PsychoPy for a masters project course, and, being relatively new to this, I’m having some trouble about how to proceed. Essentially, I’m having trouble envisioning what the randomization should look like, practically speaking (e.g., what are good functions for what I’m trying to do, etc). If you have the time to help out, I would apreciate it.
Here’s the study as detalied as I can manage.
-In all, there are 24 sounds and 24 films, divided into four categories, such that there are four categories of sound (S1-S4) and four equivalent categories of films (F1-F4), with six stimuli in every category.
-In every trial, participants should be presented with one sound from a certain category (i.e. S1), a film from the equivalent category (F1) and a film from a second category (i.e. V2). I want to investigate if participants can match at above-chance level, an so, for every trial one film should be correct and the other incorrect. I’d like randomize which is which, constrained by category (that is, a sound for F1 should be randomly matched for a film in V1, and so on).
-All sounds should be correct only once, as participants will be instructed the sounds are equivalent to words (which should only have one meaning). There is no constraint on how many times a film can be incorrect.
If there’s something I’ve missed to fill in, I’m happy to do so.
Thanks for your help,
