PsychoPy tutorial for event-related designs

Dear PsychoPy Users and Developers,
Does anyone know of any good tutorials on event-related designs in PsychoPy? (Preferably, GUI/Builder-based)
Apologies if this has already been asked elsewhere. Didn’t find anything when I searched.
Thank you very much in advance.

Best Wishes,
Alexander

P.S.:
The task I am trying to implement is very simple: object recognition with two responses (Y/N)

Sounds like you’d benefit from going to the Builder workshop
