I am trying to make a kind of oddball task.
I made 5 types of auditory stimuli (duration:1s for each, sizes:about 90kb for each).
I run these stimuli 300 times, and make participants to respond with keyboard.
Attached file is this experiment.
When I tried this task, unexpected time intervals between auditory stimuli appear many times (sometimes 5s or longer).
And sometimes, I hear this auditory stimuli are played quickly than expected, and two stimuli overlap with each other.
I saved auditory stimuli on the desktop of my note-PC, since I read the USB device driver will make unexpected delay on this forum.
My note-PC is dynabook NX/78JWH, has extra 45.5GB in C drive.
I am using superlab 4.5.2…
Could you help me to find out what causes this trouble, and what can I do for it.
