I have two questions:
First, I am wondering how I can set up a trial that includes both audio and visual stimuli and in which the audio stimulus begins 500ms after the visual stimulus is presented.
Second, I was curious if there is a way in SuperLab to start measuring RTs at a specific point within the audio stimulus. For example, I am trying to measure RTs after a variable amount of time after the audio starts. In other words, I may want to start measuring RTs 300ms after the beginning of the audio file but before the audio ends. This delay (e.g. 300 ms) varies from trial to trial.
