I know this kind of question has been asked many times by others. I want to jitter my ISI (fixation point) from 1.5 to 2.5. I inserted a code before the fixation component, which I think is logically correct. I also typed “$jitter” in the duration field. The “jitter” variable in my data file did record a random value, but that value just didn’t get reset every trial. I know I’m supposed to set the duration to change every repeat, but there is no such an option in the builder.
from numpy.random import random, randint, normal, shuffle jitter = random() * (2.5 - 1.5) + 1.5 jitter = round(jitter, 1) thisExp.addData('jitter', jitter)
Can someone help me?
