Hi there,

I know a similar issue has been posted before, but the solutions I found don't seem to be working for me, so I apologize if this is redundant. 

When I make a valid response during my trial (during enc_response), the subsequent ISI/fixation disappears before it is supposed to. I believe the issue stems from trying to display a stimulus after the response within a given trial, is this not possible?

I have it set up such that there is a variable ISI duration at the end of the trial with a fixation cross, which is to appear after the response screen. Making a valid response is quitting my subsequent stimulus presentation (the fixation), but leaving the variable duration of the trial intact (just a white screen). 

I have ensured that erase = false for all stimuli, and that responseinterrupt=trial, so the stimuli should remain on screen for the duration of the trial. 

Just for context, I suspect having my variable ISI at the end of the trial may be the issue. I tried to make a variable ISI by using the ontrialbegin attribute previously as described in other threads but it wasn't working the way that I wanted it to, which we can revisit if this is indeed the issue. 

I've added the portions of my script that I believe are relevant below, I would really appreciate any advice!

Thanks!!

I cannot seem to reproduce this -- in other words, the fixation cross is displayed fine for me, regardless of when the response occurs. A few minor things:

(1)

/ stimulustimes = [0=background_enc1; 500=target_enc1; 2500=blank; 2600=enc_response; 4600=ISI; 4601=fixation]

doesn't really make sense, as you will not get a 1ms delay between ISI and fixation (no display is fast enough to allow for that), both stimuli will be displayed at the same time, so effectively you have

/ stimulustimes = [0=background_enc1; 500=target_enc1; 2500=blank; 2600=enc_response; 4600=ISI, fixation]

(2)

Do you observe any difference between

/ responseinterrupt=trial

and

/ responseinterrupt=frames

?

(3)

If you suspect the random trial duration is the problem, does changing things to

<values>
/ randomtrialduration = 0
</values>

<trial trials_enc1>
/ ontrialbegin = [values.randomtrialduration = round(rand(5600,6600); ]
/ stimulustimes = [0=background_enc1; 500=target_enc1; 2500=blank; 2600=enc_response; 4600=ISI, fixation]
/ ontrialend = [trial.trials_enc1.resetstimulusframes()]
/ trialduration = values.randomtrialduration
/ inputdevice = keyboard
/ beginresponsetime=2600
/ validresponse = (2, 3, 10, 11)
/ responseinterrupt=frames
</trial>

make any difference?

(4)

Neither <picture background_enc1> nor <picture target_enc1> appear to be set to /erase = false. This *may* be the problem.

(5)

Finally, which version are you using currently and is your installation up to date?

I cannot seem to reproduce this -- in other words, the fixation cross is displayed fine for me, regardless of when the response occurs. A few minor things:

(1)

/ stimulustimes = [0=background_enc1; 500=target_enc1; 2500=blank; 2600=enc_response; 4600=ISI; 4601=fixation]

doesn't really make sense, as you will not get a 1ms delay between ISI and fixation (no display is fast enough to allow for that), both stimuli will be displayed at the same time, so effectively you have

/ stimulustimes = [0=background_enc1; 500=target_enc1; 2500=blank; 2600=enc_response; 4600=ISI, fixation]

(2)

Do you observe any difference between

/ responseinterrupt=trial

and

/ responseinterrupt=frames

?

(3)

If you suspect the random trial duration is the problem, does changing things to

<values>
/ randomtrialduration = 0
</values>

<trial trials_enc1>
/ ontrialbegin = [values.randomtrialduration = round(rand(5600,6600); ]
/ stimulustimes = [0=background_enc1; 500=target_enc1; 2500=blank; 2600=enc_response; 4600=ISI, fixation]
/ ontrialend = [trial.trials_enc1.resetstimulusframes()]
/ trialduration = values.randomtrialduration
/ inputdevice = keyboard
/ beginresponsetime=2600
/ validresponse = (2, 3, 10, 11)
/ responseinterrupt=frames
</trial>

make any difference?

(4)

Neither <picture background_enc1> nor <picture target_enc1> appear to be set to /erase = false. This *may* be the problem.

(5)

Finally, which version are you using currently and is your installation up to date?

The issue was indeed fixed with a software update and by adding erase to the background and target stimuli.

Thanks for your advice, and for replying so quickly!!
