Hi all,
For an experiment (pavlovian-instrumental-transfer task) I'm programming a task with 3 phases: first a very simple classical conditioning phase in which participants learn that a stimulus (apple) gets followed by a movieclip, and another stimulus (banana) gets followed by nothing. secondly an instrumental learning phase in which they click on a butterfly to get a movieclip. In a third phase, I want to present the butterfly along with either the banana or the apple for 10 seconds per trial. During these trials in the third phase, I want to count the clicks on the butterfly (without having seperate trials per click, because then the stimuli "flash" ). I expect there to be more clicks on the butterfly when accompanied by the apple compared to the banana.

How can I code this click-counting and save it in the data?

thanks a lot! I put the code underneath.

Stimuli don't "flash" (i.e. get erased at the end of a trial) when you set /erase = false in the respective stimulus elements. Have a trial that collects a single click, loop that trial for 10 seconds, count up the clicks /onTrialEnd.

/ clickCount = 0
/ timeLeft = 0
</values>

/ trialDuration = 500
/ branch = {
    return trial.clickTrial;
}
/ recordData = false
</trial>

<trial clickTrial>
/ onTrialEnd = {
    if (this.response == "clickMe") {

Hi Dave,
We are now in a phase of the study in which we think it would be convenient to provide timing for each click on the stimulus (within this trial).
For each startTrial loop (in your example above), where I count and log clicks using clickTrial, I need a way to identify each individual click in the dataset along with its timestamp. In other words, I need one row per click, including the time of that click, with the timestamp resetting to 0 at the start of every loop. I can than sum up the number of clicks (rows) within this trial myself, so it is no longer needed to sum up the number of clicks in the log trial per se (but it can stay as well, if that would be possible or not make the script too complex).
Is there a chance you could help me with that?

thank you very much!
kind regards

First change /recordData = false to /recordData = true in the respeciive <trial> element.
https://www.millisecond.com/support/docs/current/html/language/attributes/recorddata.htm

It is unclear what you understand to be the timestamp (relative to what?). You may simply wish to log the script.elapsedTime property to the data file.

Stimuli don't "flash" (i.e. get erased at the end of a trial) when you set /erase = false in the respective stimulus elements. Have a trial that collects a single click, loop that trial for 10 seconds, count up the clicks /onTrialEnd.

Hi Dave,
We are now in a phase of the study in which we think it would be convenient to provide timing for each click on the stimulus (within this trial).
For each startTrial loop (in your example above), where I count and log clicks using clickTrial, I need a way to identify each individual click in the dataset along with its timestamp. In other words, I need one row per click, including the time of that click, with the timestamp resetting to 0 at the start of every loop. I can than sum up the number of clicks (rows) within this trial myself, so it is no longer needed to sum up the number of clicks in the log trial per se (but it can stay as well, if that would be possible or not make the script too complex).
Is there a chance you could help me with that?

thank you very much!
kind regards

Hi all,
For an experiment (pavlovian-instrumental-transfer task) I'm programming a task with 3 phases: first a very simple classical conditioning phase in which participants learn that a stimulus (apple) gets followed by a movieclip, and another stimulus (banana) gets followed by nothing. secondly an instrumental learning phase in which they click on a butterfly to get a movieclip. In a third phase, I want to present the butterfly along with either the banana or the apple for 10 seconds per trial. During these trials in the third phase, I want to count the clicks on the butterfly (without having seperate trials per click, because then the stimuli "flash" ). I expect there to be more clicks on the butterfly when accompanied by the apple compared to the banana.

How can I code this click-counting and save it in the data?

thanks a lot! I put the code underneath.
