I’ve written a prepulse inhibition paradigm that presents one of six audio files that vary in length but presenting them all through one event instance. I’ve noticed some odd behavior in the way superlab presents these. There are three durations - 70, 100, and 160ms. When I specify to present these within a 1000ms event, the 100 and 160ms stimuli get cut off. When I specify 1000ms event and turn on “keep playing audio and stop it when trial ends” they present normally.
I don’t understand why this would be since a 1000ms event is longer than the longest stimulus, so this should be an adequate amount of time in which to present the 100 and 160ms stimuli. Ideally, I would be able to indicate to superlab to play each audio stimulus for the time it takes and then move on, instead of specifying an event duration. Wanted to make sure I understood any possible timing issues before I proceeded with this setup. I’ve attached both. Any help is appreciated. Thanks
