I’m using 4.07b with a touch screen system for monkeys. I am presenting a series of stimuli to a subject, each of which has to be touched to advance the series to the next stimulus. All stimuli stay on the screen throughout the trial. At the end of the series the subject has to classify the series as either A or B (correct or incorrect; A and B are stimuli that come up after the last element in the series comes on and is responded to). If A is correct, and the subject touches A, then it receives food. If it presses B, I go to a dark screen, which I do using the feedback function, “Response is not correct.”
All of this is easy enough to program. But, I find that when the subject touches one of the series of stimuli (which I want to remain on the screen while the monkeys are making a choice) while A and B are on the screen, that response is also treated as an incorrect response, and the program goes to the dark screen. It appears that Superlab treats any designated response location other than the one designated as correct, to be part of the incorrect response.
I’ve tried erasing the screen before A and B come up, but still, responses to those other response locations (which monkeys tend to do) end the trial and produce the dark screen. I can eliminate touches to non-designated areas of the screen using one of the response options, “ignore a mouse click . . .”
Is there a way to uniquely designate a particular location as “incorrect” (as you can for a correct response), so that only a response to that area will produce the end of the trial?
