Simultaneous presentation of beeps and pictures
I want to create an experiment with the following characteristics:
-9 pictures will be presented and each picture will be presented for 9 seconds
-During the presentation of one picture, beeps have to be presented with random intervals of 1500 or 900 miliseconds (I have an audiofile of one beep which will be rehearsed with different intervals: set duration [interval]). Participants have to react as quickly as possible on the beeps.
-After the presentation of one picture, participants have to rate the picture (pleasantness 1-9).
I managed to make an experiment with only the pictures and one experiment with only the beeps with random intervals.
Could someone give me some tips how I could present the pictures and beeps (with random intervals) simultaneously?
Thanks in advance!
