Hello,
I'm trying to create a match-to-sample task. I need to be able to present a random stimulus from a list in the "probe" location and simultaneously present that same stimulus (or one from the same position on a different list) in the "target" location. In reading about yoking, it appears as though that only works across trials rather than within trials. Am I incorrect?
For clarity, I also need to simultaneously present 5 distractors from the same list as the probe, but none can match the probe.
Finally, I would like to use a home key. That is, a key press to start the trial, a key release to clear the screen and measure decision time, and RT to continue recording until the answer key is selected. Is this possible?
Many thanks,
Meredith
