Random assignment to different feedbackpages

Hi,

I'm having difficulty understanding how I can randomly assign two groups of participant to two different feedback pages.
The idea is that all participants will first see the instruction page, then answer some demographic questions, and then some questions from a questionnaire.

I want to manipulate the feedback they receive at the end (regardless of their actual answers). This will be a normal page, something like "You did well" or "You did poor".

I made two conditions, with different 'blocks' (not sure if this is correct?):

<expt conditionA>
/ subjects = (1 of 2)
/ groupassignment = random
/ blocks = [1=Intro; 2=Demographic; 3=Questionnaire; 4=FeedbackA]
</expt>

<expt conditionB>
/ subjects = (2 of 2)
/ groupassignment = random
/ blocks = [1=Intro; 2=Demographic; 3=Questionnaire; FeedbackB]
</expt>

Then, I made survey's  and surveypages for each block?
So, for Intro

<survey Intro>
/ pages = [1=Intropag]
</survey>

<surveypage Intropag>
/ caption =
"







In deze vragenlijst wordt er naar je fitheid en gezondheid gevraagd.
Beantwoord elke vraag door het juiste hokje aan te kruisen of te antwoorden op de stippellijn.
Wanneer je twijfelt over een antwoord op een vraag, probeer dan het antwoord te geven dat het meest op jou van toepassing is."
/ fontstyle = ("Calibri", -18, true, false, false, false, 5, 0)
/ nextlabel = "Volgende"
</surveypage>

and for Questionnaire:

<survey Questionnaire>
/ pages = [1=QP1; 2=QP2; 3=QP3; 4=QP4; 5=QP5]
</survey>

<surveypage QP1>
/ caption = "De volgende vragen gaan over sporten. Houdt bij het beantwoorden de afgelopen maand in gedachten."
/ fontstyle = ("Calibri", -16, true, false, false, false, 5, 0)
/ questions = [1=sportuur; 2=sport]
/nextlabel = "Volgende"
</surveypage>
Etcetera


So this does not work.
I don't know if it is possible to make these 'blocks', or if I'm doing it all wrong.
I really hope someone can help me with this.

A <survey> is a type of <block>, so yes, you can run those via an <expt> element's /blocks attribute. The /blocks attribute will accept either <block> or <survey> elements, nothing else.

A <surveypage> is a kind of <trial> element. Apart from running it via a <survey> element's /pages attribute, you can run it via a <block> element's /trials attribute.

As for what's "wrong" with your script as it stands, it is impossible to tell based on those few snippets you posted. Your 2nd <expt> definitely contains errors, though:

<expt conditionB>
/ subjects = (2 of 2)
/ groupassignment = random
/ blocks = [1=Intro; 2=Demographic; 3=Questionnaire; FeedbackB]
</expt>

In general, I would recommend working through all the various tutorials contained in the Inquisit documentation to acquire the basics of setting up a procedure and familiarizing yourself with the most important syntax constructs.

Thank for your reply!
I now know that I did use the right syntax constructs here :).
Indeed I made a stupid mistake when using the / caption option in my script.
Glad it works.


Thanks again
