I need to set variable intervals to display visual stimuli and want these intervals to have a normal distribution. Is there a method to approximate a normal distributed sampler using 'rand' or one of the other existing random number generators?

Thank you very much!

    Hi Marisol,

    Probably the easiest thing would be to use Python's random module via a Python action, e.g.

    run_python_string ('import random')
    value = py_call('random.gauss', mean, std_dev)
