[open] simultaneous presentation of stimuli
Dear All, we are trying to present stimuli simultaneously which in itself does not seem to be problematic at all. However, we would like to present a visual stimulus first and have it running for say 3000ms, but after 2000ms we would like to present simultaneously an auditory stimulus. Right now we are presenting the picture for 2000 ms and then have the same picture selected again together with the auditory stimulus. We are a little worried that depending on the computer the new selection of the picture might cause jitter in the presentation.
Is there a way that we can present the picture for the entire duration (3000ms) and present the auditory stimulus simultaneously for the last 1000ms of this duration.
I hope I was able to make my query clear enough!
Thanks in advance!
