I’m using the builder to develop my experiment. We want to present a drifting grating 25 times (4sec each time) with a black screen presented for a random amount of time (between 1.5 and 3sec) between each grating presentation.
Here is a picture of my builder :
The « Random black screen » should go right after the Grating, before the loop begins.
However, I do not see any components to allow me to add this kind operation in the builder !
How can I achieve that ? (I am a complete beginner to coding)
