I am working on a research project in which audio files need to be presented to a panel of listeners and they will rate the audio files on a set of characteristics. My needs include:
A way to randomize the audio files that each user gets BUT each user must rate each file they are assigned twice (to get intra-rater reliability). Also, each file has to be rated by 3 different raters (for inter-rater reliability). Can PsychoPy somehow automate this process? As you can see, it can be quite complicated to figure this out by hand.
The types of ratings that are required are made on a single horizontal line. There are no numerical values on the line but there are labels “minimal, moderate and severe” under the line (It’s a visual analog scale- VAS). The rater will decide how severe each characteristic of interest is for a particular audio file and click on the line to indicate severity. I would need a numerical value (0-100) based on where they click on that line (but the user should not see this number).
Is this sort of randomization (assigning specific audio files to different users) as well as the VAS scale possible to build using PsychoPY? I’m just trying to get an idea as it whether it’s possible before I delve so far into learning how to use the product. Thank you in advance for any leads.
