bgstim not being presented

By Shona - 5/26/2014

Hi, 

A response scale is supposed to be presented on the screen during a block of trials. I have therefore entered /bgstim = (likertlabel) in this block. However, the likert scale is not showing up. Do you have any ideas why? My entire script is pasted below. 

Thanks again!

A stimulus displayed by /bgstim gets drawn to the screen only *once*, at the very beginning of the <block>. If any other stimulus in that block overwrites the background stimulus, it will be gone for good. That's exactly what happens with yours, specifically via

<text instructions2>
/ items = instructions2
/ hjustify = left
/ size = (90%, 80%)
/ position = (50%, 85%)
/ valign = bottom
/ select = sequence
</text>

displayed by

<trial instructions2>
/ stimulustimes = [1=instructions2, spacebar]
/ correctresponse = (" ")
/ errormessage = false
/ recorddata = false
</trial>

which is the first trial in the relevant block

<block political>
/ bgstim = (likertlabel)
/ trials = [1 = instructions2; 2-106 = noreplacenorepeat(political)]
</block>
