Thanks for your quick response so…
I’ll be more explicit…
Participant Input is set to Mouse/Touchscreen, for which there are three distinct mouse/touchscreen response areas (the sample, left comparison stimulus, and right comparison stimulus). I have tried every combination of setting the 3 aforementioned response areas to (a) automatically determined and (b) assigning specific x, y coordinates and length and width dimensions, but no modification results in it working the way you have described.
(1) Trial 1 Event 1 is a visual stimulus (the sample, which is shown exactly at the sample response area).
—Presentation options set to do nothing at the end of the event.
—It is set to end after a correct response from a participant.
—The correct response from a participant is set to touching the sample response area.
—Feedback is set to sounding an an auditory Event called the sample touched tone.
So the sample is presented on the screen and subjects must touch it, after which the sample tone sounds and the next event is presented with the sample remaining on the screen. The important part is that touching the sample visual stimulus/response location is a correct response in Trial 1 Event 1 but it should not be correct or incorrect in any subsequent Trial.
(2) Trial 2 Event 2 is a visual stimulus (the left comparison stimulus that is shown at the left comparison stimulus response area)
—Presentation options set to remain invisible
----It is set to end only after a time limit of 1 ms.
----No feedback set
----Correct responses set to the subject must not respond.
So these settings allow this stimulus to be presented at the same time as the final stimulus in Event 3 and it seems that altering the feedback or correct response settings have no effect at all.
(3) Trial 2 Event 3 is a visual stimulus (the right comparison stimulus that is shown at the right comparison stimulus response area)
—Presentation options to remain invisible not checked so that it is simultaneously presented with Trial 2 Event 2
—It is set to end either after a correct response from participants or after any response from participants because neither seems to change anything).
—Correct response from participant set to touching the right comparison stimulus response area.
—Feedback set to sounding an auditory event called correct response tone Event for correct responses and sounding an auditory event called incorrect response tone Event for incorrect responses.
The problem is that the sample response area is still active and registering touches as well as the left and right comparison stimulus areas during Trial 2. Touches to the sample stimulus results in an incorrect response being registered (when at this point a touch to it should not be registered), touches to the left comparison stimulus results in an incorrect response being registered (this is good), and touches to the right comparison stimulus results in a correct response being registered (this is good).
I’ve attached my work in progress which shows this happening. I thought that it was happening perhaps because I am trying to create a simultaneous matching to sample task so the sample remains on the screen with the comparison stimuli, but when I select Erase screen or Erase Stimulus such that the sample is removed from the screen I still have the same problem (i.e., a touch to the sample respones area even though the sample visual stimulus is not displayed results in the incorrect response being registered).
If the sample response area cannot be turned off in subsequent Trials then I must discriminate THREE responses (correct response, incorrect responses, and touch to the sample) because the response area for the sample stimulus presented in Event 1 (which is in Trial 1) is still active when Event 2 (correct) and Event 3 (incorrect so it is left unchecked) are simultaneously presented in Trial 2 even though subjects have already touched the sample in Event 1 Trial 1 and even though no matter what the mouse/touchscreen response settings are set to (i.e., automatically determined or specific area defined).
Again, I have tried every configuration with your modifications/suggestions and still run into the same problem. I am a new user so any help is appreciated. I have searched through all of the postings to see if any solutions are available, but so far no such luck.
