Randomised Timings, Location and Orientation for Stimuli

Builder

  1. Trying to make a picture appear for 100ms 50% of the time and 500ms for 50% (randomly) across 128 trials.

  2. Trying to make a square appear to the left 50% of the time and to the right 50% of the time (randomly) across 128 trials.

  3. Trying to make a line appear horizontally 50% and vertically 50% of the time (randomly) across 128 trials.

I don’t know how to code at all. Can this be done just using the builder view?

Thanks,
Jan

Hi,

you can do all those thing in builder view using loops: Flow — PsychoPy v2020.2
