Millisecond Forums

Hi Dave,
I wish to design an experiment with the following process:
The trial begins with a fixation.
"A" shows up at an variable onset and disappears until the onset of "B" (A's offset overlaps with B' onset).
"B" lasts 2s before disappearance.
The response (press the space) can only be made after the onset of A and does not affect the presentation of B, and the time point of response release is recorded.
The onset of B is drawn from a guassian distribution with a fixed mu and sigma (I have read https://www.millisecond.com/forums/Topic8431.aspx#bm8437, but still do not how to apply it into to my syntax).




Would you help me fix my script?
Best,
Nakayama
