Single & Multi Choice Trials in Same Timing File

Hi Jaewon!

I would like to be able to present either a single task object or two task objects within the same conditions file and likely within the same block. It appears to be the case that SingleTarget can only be used for one target at a time and MultiTarget needs at least two task objects. I currently have a second object the same as the screen background color as a place holder for single-choice trials using MultiTarget, but it appears that this will not work long term as the marmosets like to lean on the touch screen.

Is there a simple way to implement this structure or will I need to create my own tracker to do such a thing?

Thank you,

E

Create two scenes; one with one stimulus and SingleTarget; the other with two stimuli and MultiTarget. Then run only one of them, depending on your need.
