Double target task

Hi Jaewon.

I am programming a double target task.
In this task, targets can appear at different times relative to each other (target 1 earlier or later than target 2) and the animal gets rewarded for an eye movement to either of the target locations (which are in opposite sides of the lower visual field).
I am using a TimeCounter & CircleGraphic to create each of the target scenes, for target 1 and 2 independently.

Then, I use the SingleTarget adapter for each of the target locations, the OrAdapter to add them together, and the WaitThenHold last, so that when the eye movement is executed to either of the targets, there is a reward.
Is there a practical way to record "which" of the targets was reached from the Success outcome?

Thank you very much for your help. Please let me know if I should copy the code here instead.

You said you used two SingleTarget adapters. Check their Success properties after the scene ends. One should be true, while the other is false.

Thank you Jaewon.

How can I make such that once either of the targets is reached (either target 1 or target 2), the animal must keep fixation there (hold), otherwise if goes out of that target window, the trial is wrong.

I know I can access adapter.Success, but what are the other properties I can access on real time?

Try the MultiTarget adapter.

You cannot access adapter properties on real time, unless you make your own adapters. What you can do in the timing script level is to set input properties, call run_scene() and check output properties after the scene ends. Basically you are interacting with adapters from their outside. The "real time" changes occur during run_scene() and you need to be inside the adapter to get property values that are changing from moment to moment.

For available properties of each adapter, please see the manual.

Got it. Thank you Jaewon.

One last question, I noticed the Inter Trial Time keeps increasing over time.
I also get a warning: "Desired ITI exceeded". This does not happen in any of the other tasks I have. In all of my tasks I use a set iti time (1000ms) in the last line.
How can I fix this?

I guess you may be saving a huge variable whose size is growing every trial.

Not saving any variable or doing anything different to my other visual tasks. The only difference in this task is that I use
the OrAdapter.

Do you mind if I send you my code for you or someone else in the NIMH MonkeyLogic group, to run it and take a look? For 200 trials, the ITI increases to 8000ms

You can send it to me via Private Messages.

You set your filetype to .mat. Change it to .bhv2 and see if there is any difference.

And see this manual page written about the file format.
