Hi,

I have what I hope is a quick question.

So I have this current script:

<item male_happy>
/1 = "057_y_m_h_b.jpg"
</item>

<picture male_happy>
/ items = male_happy
/ position = (25%,50%)
/ size = (30%,30%)
</picture>

<item happy>
/1 = "happy"
</item>

<text happy>
/ items = happy
/ fontstyle = ("Arial", 50pt, true)
/ position = (25%,50%)
</text>

<counter hpositions>
/ items = (25%, 75%)
/ select = noreplace
/ selectionrate = always
</counter>

<counter vpositions>
/ items = (25%,75%)
/ select = noreplace
/ selectionrate = always
</counter>

<trial H_happy>
/ ontrialbegin = [picture.male_happy.hposition=counter.hpositions.selectedvalue;
  text.happy.hposition=counter.hpositions.selectedvalue;
    text.happy.vposition=counter.vpositions.selectedvalue]
/ stimulusframes = [1=male_happy, happy]
/ validresponse = (203,205)
/ correctresponse = (205)
</trial>

And I want to add another face, male_happy, to the trial but I want it to be at the same x position as the text happy on every trial. How would I do this? Any links or suggestions would be appreciated.

Then you ought so select the position for the "happy" text element first and then set the picture's x position to that of the text.

<trial H_happy>
/ ontrialbegin = [
  text.happy.hposition=counter.hpositions.selectedvalue;
    text.happy.vposition=counter.vpositions.selectedvalue;
    picture.male_happy.hposition=text.happy.hposition;]
/ stimulusframes = [1=male_happy, happy]
/ validresponse = (203,205)
/ correctresponse = (205)
</trial>

/ stimulusframes = [1=male_happy, happy]
/ validresponse = (203,205)
/ correctresponse = (205)
</trial>

Oh yes thank you!

One follow up question, if I want to add an X on top of the trial if they answer incorrectly I add a branch to another trial. I have done this in the past but for some reason when I implement it now, it uses a different face (male_happy) for the error page.

Here is a sample trial:
<trial H_happy>
/ ontrialbegin = [picture.male_happy.hposition=counter.hpositions.selectedvalue;
  text.happy.hposition=counter.hpositions.selectedvalue;
    text.happy.vposition=counter.vpositions.selectedvalue]
/ stimulusframes = [1=male_happy, happy]
/ validresponse = (203,205)
/ correctresponse = (205)
/ branch = [
    if (trial.H_happy.error) trial.error_H_happy
]
</trial>

<trial error_H_happy>
/ stimulusframes = [1=male_happy, happy, error]
/ trialduration = 600
</trial>

Any idea why this is happening? I attached the script for reference.

A selection on the picture occurs every time you display it, that's exactly what is supposed to happen.

And you don't need another trial, you simply need /errormessage in <trial H_happy>.

In another post I read that error message does not allow you display multiple stimuli and that the best solution was to use another trial. Is that not true?

I need to display male_happy, happy, and error at the same time if they answer incorrectly.

The trial here already displays the other stimuli (the word and the image), so this is not relevant. What you are referring to was an entirely different situation.

<item male_happy>
/1 = "057_y_m_h_b.jpg"
</item>

<picture male_happy>
/ items = male_happy
/ position = (25%,50%)
/ size = (30%,30%)
/ erase = false
</picture>

<item happy>
/1 = "happy"
</item>

<text happy>
/ items = happy
/ fontstyle = ("Arial", 50pt, true)
/ position = (25%,50%)
/ erase = false
</text>

<counter hpositions>
/ items = (25%, 75%)
/ select = noreplace
/ selectionrate = always
</counter>

<counter vpositions>
/ items = (25%,75%)
/ select = noreplace
/ selectionrate = always
</counter>

<trial H_happy>
/ ontrialbegin = [
text.happy.hposition=counter.hpositions.selectedvalue;
  text.happy.vposition=counter.vpositions.selectedvalue;
  picture.male_happy.hposition=text.happy.hposition;]
/ stimulusframes = [1=clearscreen, male_happy, happy]
/ validresponse = (203,205)
/ correctresponse = (205)
/ errormessage = true(error, 600)
</trial>

<text error>
/ items = ("X")
/ fontstyle = ("Arial", 200pt, true)
/ position = (50%,50%)
/ txbgcolor = transparent
/ txcolor = black
</text>

This makes a lot of sense, and will save me a ton of time. Thank you

I just fixed my script but this keeps the stimuli on for all the trials. Is there a way to erase it once the trial is over?
Otherwise the previous trials stimulus remains on the screen during the next trial.
