I'm running an experiment and need to implement a jitter between trials. I need the jitter to range from 1100ms to 4600ms and be random. The instructions for the advanced_delay plugin are confusing to me...I think I put the average of the two numbers in the duration box, which would be 2850ms. I've also put 870ms in the jitter box, with a standard deviation jitter. Can anyone provide any guidance on this?
