Hi everyone! I am new to PsychoPy but really struggle with making it work.
I wish to make an experiment in which the participants will have to identify voices. The participants will first have to go through a “training phase”, in which they will be presented with 8 audio files of different people speaking one at a time. Each audiofile is 30s long and placed in a subfolder called “stimuli” in the same directory as my experiment. The audiofiles are .wav format. I have made an excel sheet in which the top of the column says “Trainfile”, and each cell below this includes a unique path to the audiofiles I wish to include in the loop (an example is the following: stimuli/audiotrain1female.wav).
What are you trying to achieve?:
What I am struggling with is how to include these audiofiles in a loop (in a random order). After one audioclip has played, there should be a text saying “Press any key to hear the next voice”. The participant should then press a key and the next audiofile should start playing. This is the structure that I have made so far.
What did you try to make it work?:
I tried to add the excel file in the trainloop. Don’t know if I did something wrong?
What specifically went wrong when you tried that?:
I get this error message:
