Simultaneous Visual and Auditory Stimulus


I am trying to present a visual stimulus and an auditory stimulus simultaneously, I have the two paired up but it the auditory stimulus keeps lagging behind the visual stimulus. The visual will appear, then the auditory will play and they’ll both end at the same time (even though they are both set to last 1000 milliseconds).

In the events list I have the visual event before the auditory; when I switch them the sound will start before the picture appears.

Thanks so much for your help

Whichever event that precedes the other should end Immediately after the event is presented.
