customize trial duration

[ZifengLIU143]

Hi,

I am programming an audio-button response task. The duration of my audio stimuli is not consistent. At the end of the audio, I want to add more 2000ms to allow participants to make a response. Beyond this trial duration, participants will be forced to move to the next trial. I can do this by adding a conditional timeline, but I do not know how to customize the trial duration. Any suggestion from you guys?

Thank you in advance,

Zifeng
