Images in a likert scale

mhenein — Mon, 02 Nov 2015 14:44:19 GMT

I was wondering if anyone has ever tried to use images as stimuli in a likert scale measure. I am trying to add a different picture for each question but when I run the experiment it won't show the image, it just shows the name of the image. Anybody have any adivce? I've attached my script below.

<expt>
/ blocks = [1=likertsb]
</expt>

<text sb>
/size = (500, 70)
/items = sbquests
/position = (50, 50)
/halign = center
/select = noreplace
</text>

<item sbquests>
/1 = "bm1.gif"
/2 = "bm2.gif"
/3 = "bm3.gif"
/4 = "bm4.gif"
/5 = "bm5.gif"
/6 = "wm2.gif"
/7 = "wm1.gif"
/8 = "wm3.gif"
/9 = "wm4.gif"
/10 = "wm5.gif"
</item>

<picture black>
/ numitems = 5
/ select = RANDOM
/ items = ("bm1.gif", "bm2.gif", "bm3.gif", "bm4.gif", "bm5.gif")
</picture>

<picture white>
/ numitems = 5
/ select = RANDOM
/ items = ( "wm1.gif", "wm2.gif", "wm3.gif", "wm4.gif", "wm5.gif")
</picture>

<likert sb>
/buttonvalues = [1="0"; 2="1"; 3="2"; 4="3";5="4"; 6="5";7="6"]
/ anchors = [1="Not at all similar to me"; 7="Extremely similar to me"]
/ stimulusframes = [1 = sb]
/anchorwidth = 120
/inputdevice= mouse
/ mouse=true
/ numpoints=7
/ position= (50, 80)
</likert>

<block likertsb>
/ preinstructions=(rate_sb)
/ trials = [1-10 = sb]
</block>

Of course that's possible. Set up a <text> element containing your question(s) and display it via /stimulusframes along with the <picture>. /stimulusframes and -times are not restricted to displaying only a single stimulus, you can display however many you want or need.

Thank you! That worked! Is there a way though that I can add text to this. I would like a question (the same page) to appear on each page along with the picture. I'm not sure if that is possible from the tutorials I have looked at.

Your <likert> is *not* displaying the <picture> element. It is displaying a <text> element, <text sb> to be precise.

<likert sb>
...
/ stimulusframes = [1 = sb]
...
</likert>

<text sb>
...
/items = sbquests
...
</text>

If you want it to display a <picture> element, display said element via the <likert>'s /stimulusframes just like you would any other stimulus in any other regular <trial>.

<picture mypicture>
/ items = pictureitems
...
</picture>

<item pictureitems>
/ 1 = "A.jpg"
/ 2 = "B.jpg"
...
</item>

<likert somelikert>
/ stimulusframes = [1=mypicture, ...]
...
</likert>

You'll find those basics covered in more detail in the tutorials contained in the Inquisit documentation. I you haven't done so yet, I'd recommend giving those a spin.
