Hello,
I would like to have a series of pictures evaluated. I created a surveypage element in which each picture is presented with a slider. If I use the <image> element however, I do not have the name of the file that was presented to the participant listed anywhere in the results file. How can I fix this so that I can tell the order with which the pictures were presented to participants?
Thank you in advance for your help!
<item valence>
/1 = "prime_lit1.jpg"
/2 = "prime_lit2.jpg"
/3 = "prime_lit3.jpg"
/4 = "prime_lit4.jpg"
/5 = "prime_lit5.jpg"
</item>
<image val>
/items = valence
/position = (6.25%,2%)
</image>
<slider slid_val>
/ fontstyle = ("Arial", 4%)
/ position = (14%, 75%)
/ labels = ("Negative", "Positive")
/ range = (1,9)
/ slidersize = (60%, 6%)
/ showtooltips = false
/ required = true
</slider>
<surveypage Explicit1>
/ fontstyle = ("Arial", 3%, false, true)
/ questions=[1=val;2=slid_val]
/ showpagenumbers = false
/ showquestionnumbers = false
/ finishlabel = "Next"
/ nextbuttonposition = (60%, 90%)
</surveypage>

To do this, you need to employ a bit of trickery. One way is to have a <picture> element displayed of-screen on the <surveypage>, with the <image> element referencing that <picture>'s current item:
<block myblock>
/ trials = [1-5=Explicit1]
</block>
<item valence>
/1 = "prime_lit1.jpg"
/2 = "prime_lit2.jpg"
/3 = "prime_lit3.jpg"
/4 = "prime_lit4.jpg"
/5 = "prime_lit5.jpg"
</item>
<picture valpic>
/ items = valence
/ position = (-20%,-20%)
</picture>
<image val>
/items = ("<%picture.valpic.currentitem%>")
/position = (6.25%,2%)
</image>
<slider slid_val>
/ fontstyle = ("Arial", 4%)
/ position = (14%, 75%)
/ labels = ("Negative", "Positive")
/ range = (1,9)
/ slidersize = (60%, 6%)
/ showtooltips = false
/ required = true
</slider>
<surveypage Explicit1>
/ stimulusframes = [1=valpic]
/ fontstyle = ("Arial", 3%, false, true)
/ questions=[1=val;2=slid_val]
/ showpagenumbers = false
/ showquestionnumbers = false
/ finishlabel = "Next"
/ nextbuttonposition = (60%, 90%)
</surveypage>

Thank you for your quick reply.
I tried to implement the changes that you suggested but it looks like
/items = ("<%picture.valpic.currentitem%>")
in the image element is not recognized. The error says "File not found".
Is there anything else that need to be done?
Thank you,
IR

Code works for me as given in my response (tested under 4.0.7.0) provided that the image files are where they're supposed to be (same folder as the script).

Attaching complete example (including images).

I updated my version of Inquisit (I was using the previous one) and now it works.
Thank you!!
