[open] Stimulus presentation and keyboard response
I am making an n back task that I will be using for an fMRI experiment. I am having trouble understanding how to setup the sketchpad and keyboard response items to get the behavior I want.
This is each trial should work:
Display stimulus for 500ms.
Display fixation dot for 1500 ms.
Collect a response provided any time during that period and don't change the screen in response to a keypress. This way the timing of each trial is constant.
How would I set this up in open sesame?

Welcome to the forum.
To present a sketchpad for a constant time, regardless of the response time, you could have a look at this previous post:
Does this solve your question? If not, please let us know!
