Dear all,

I'm trying to create a task in which participants can view many different pictures and choose one picture when they decide to. This meant that I want them to be able to freely click "Back" to view the previous picture, and "Continue" to view the next picture. I have 110 pictures, and when participants decide which painting they want to choose, they can either continue to view other pictures or end the task. I have been able to achieve all the procedures I want except that when participants clicked on "Back", they were not shown the previous picture, rather it was a new, randomly chosen, picture.

Does anyone know how I can display the previous picture when participants click on "Back"?

Below are the script that I have right now:

<radiobuttons choose>
/ options = ("This painting has the highest price", "Continue viewing other paintings")
/ optionvalues = ("1", "0")
/ validresponse = ("1","0")
/ position = (35%, 65%)
</radiobuttons>

<radiobuttons ask>
/ options = ("Yes, I want to continue viewing other paintings", "No, I don't want to view more paintings")
/ optionvalues = ("1", "0")
/ position = (25%, 40%)
</radiobuttons>

<radiobuttons endask>
/ options = ("Show me other paintings", "End Task")
/ optionvalues = ("1", "0")
/ position = (35%, 65%)
</radiobuttons>

<surveypage init>
/ stimulustimes = [1=blank]
/ response = noresponse
/ branch = [surveypage.choice]
/ recorddata = false
</surveypage>

<surveypage end>

/branch = [if(radiobuttons.endask.response==0) surveypage.endtask]
/branch = [if(radiobuttons.endask.response==1) surveypage.end]

<survey test>

Will greatly appreciate any help on this matter! Thank you so much!

Best,
