Blank pages between randimized surveyspages and randomization with constraints

mongrel — Thu, 27 Feb 2020 09:07:24 GMT

Hello everybody,

I have an explicit attitude questionnaire with one item-picture and three response scales on each page.
Now, I have two questions:

1. I would like the items to be presented in randimized order with certain constraints (e.g., B should never follow A, E should never be presented after D...). Is that possible? How?
2. Also, I would like to show blank pages between surveypages containing items. Is that possible? How?

Thank you very much in advance!
Best,
Ronja

Hi Dave,

one last question:
I tried to insert blank pages after each survey page via branch as you suggested. Could you have a look?
This is, what I would do with every survey page. The error message is: Could not locate element blank.

<surveypage B4>
/ subcaption = "Wie wirkt diese Person auf Sie?"
/ subcaptionfontstyle = ("Arial", 2.5%, true, false, false, false, 5, 0)
/ showquestionnumbers = false
/ questions = [1=B4; 2=negpos; 3=symp]
/ finishlabel = "Weiter"
/ nextbuttonposition = (47, 95)
/ showbackbutton=false
/ showpagenumbers = false
/ branch = [if (next) trial.blank]
</surveypage>

***What I want to say with this branch is: If participants press nextbutton (what they all will do), show trial blank.

<trial blank>
/stimulusframes = [1 = blank]
/trialduration = 1000
</trial>

<item blank>
/1 = "blank.png"
</item>

<image blank>
/ items = ("blank.png")
/ position = (37%, 15%)
/ imagesize = (33%,33%)
</image>

Thank you very much!

All you need is

/ branch = [trial.blank]

Always that easy... Thanks, Dav!

OK, Dave, I realized that you answered everything in the second script you sent!
Thank you so, so much!

Hey Dave,

thanks for the quick reply! I have a few more questions, though.
1. It is not possible to use list for surveypages, right? Each item is on one page, see attached script. How can I randomize surveypages with certain constraints? And...
2. If I run the survey as a block, I have to change the surveypages into trials and cannot use sliders anymore, right?
Thank you very much!

> 1. It is not possible to use list for surveypages, right?

It's perfectly possible.

> 2. If I run the survey as a block, I have to change the surveypages into trials and cannot use sliders anymore, right?

No. A <surveypage> *is* a special type of <trial>, you can run <surveypage>s per a <block>'s /trials attribute or any other means, just like regular <trial> elements.
[/quote]

Note: I can't say anything about the script you attached, because it's unclear to me what exactly you want it to do. It does not seem to correspond to your initial description:

" I would like the items to be presented in randimized order with certain constraints (e.g., B should never follow A, E should never be presented after D...)."

In the script, there are only elements designated A and B, so I'm not sure how "B should never follow A" is supposed to be achievable.
[/quote]

Thanks a lot!
Sorry, that must have been confusing. A1 is not supposed to follow A and the other way around, B should not follow B1 and the other way around. (I just called them A and B when I thought there would not be any need to attach the script...).
[/quote]

Okay, and what is and isn't supposed to follow A1, A2, etc. and B1, B2, etc. Can you spell that out, please, and please do so completely
[/quote]

OK, so:

All surveypages should be presented in randomized order. However, A1 should never follow after participants saw A and the other way around, meaning: After A: A2, A3, A4, B, B1, B2, B3, B4 are allowed, only A1 is not allowed to follow A. Same for A1 with A; after A1: A2, A3, A4, B, B1, B2, B3, B4 are allowed, only A is not allowed to follow A1. Same with B and B1; after B; A, A1, A2, A3, A4, B2, B3, B4 are allowed, only B1 is not allowed to follow B. And the other way around: after B1: A, A1, A2, A3, A4, B2, B3, B4 are allowed, only B is not allowed to follow B1. All others should be randomized and there are no constraints to that. I hope, it makes more sense now.
[/quote]

Okay, thanks. Well, in principle, you'd do something like this:

<surveypage A>
/ ontrialbegin = [
values.do_not_select = surveypage.A1;
]
/ subcaption = "Wie wirkt diese Person auf Sie?"
/ subcaptionfontstyle = ("Arial", 2.5%, true, false, false, false, 5, 0)
/ showquestionnumbers = false
/ questions = [1=A; 2=negpos; 3=symp]
/ nextlabel = "Weiter"
/ nextbuttonposition = (47, 95)
/ showbackbutton=false
</surveypage>

<surveypage A1>
/ ontrialbegin = [
values.do_not_select = surveypage.A;
]
/ subcaption = "Wie wirkt diese Person auf Sie?"
/ subcaptionfontstyle = ("Arial", 2.5%, true, false, false, false, 5, 0)
/ showquestionnumbers = false
/ questions = [1=A1; 2=negpos; 3=symp]
/ nextlabel = "Weiter"
/ nextbuttonposition = (47, 95)
/ showbackbutton=false
</surveypage>

setting values.do_not_select to "" otherwise and using that as the /not constraint:

<list items>
/items = (surveypage.A surveypage.A1 surveypage.A2 surveypage.A3 surveypage.A4 surveypage.B surveypage.B1 surveypage.B2 surveypage.B3 surveypage.B4)
/ not = (values.do_not_select)
/ replace = false
/ selectionmode = random
</list>

You're going to run into a problem, though, because randomization happens on the fly: It's perfectly possible that for the last two trials only A and A1 (or B and B1) are left to be sampled in the list. Then the constraint has to be dropped and you'd get A followed by A1 (or vice versa). If you want to avoid that, you need to write an algorithm that constructs a valid sequence in advance and then just have the remainder of the script run that sequence.

Hey Dave,

thanks again for your help!
I am not quite sure how to understand: "setting values.do_not_select to "" otherwise and using that as the /not constraint:"
If I copy your script as is, Inquisit complains: "Expression 'values.do_not_select' is invalid. Expression contains an unknown element or property." So, I figure, I have to define values.do_not_select first? If so,

[/quote]

wasn't finished yet...

Questions are:
1. Do I have to define Values.do_not-select and if so, how? I never worked with expressions, sorry!
2. Is it true that I do not have to draw items from the list in the survey because it is done in each surveypage this way?

Hey Dave,

thanks for the quick reply! I have a few more questions, though.
1. It is not possible to use list for surveypages, right? Each item is on one page, see attached script. How can I randomize surveypages with certain constraints? And...
2. If I run the survey as a block, I have to change the surveypages into trials and cannot use sliders anymore, right?
Thank you very much!
Best,
R

> 1. It is not possible to use list for surveypages, right?

It's perfectly possible.

> 2. If I run the survey as a block, I have to change the surveypages into trials and cannot use sliders anymore, right?

No. A <surveypage> *is* a special type of <trial>, you can run <surveypage>s per a <block>'s /trials attribute or any other means, just like regular <trial> elements.
[/quote]

Note: I can't say anything about the script you attached, because it's unclear to me what exactly you want it to do. It does not seem to correspond to your initial description:

" I would like the items to be presented in randimized order with certain constraints (e.g., B should never follow A, E should never be presented after D...)."

In the script, there are only elements designated A and B, so I'm not sure how "B should never follow A" is supposed to be achievable.
[/quote]

Thanks a lot!
Sorry, that must have been confusing. A1 is not supposed to follow A and the other way around, B should not follow B1 and the other way around. (I just called them A and B when I thought there would not be any need to attach the script...).
[/quote]

Okay, and what is and isn't supposed to follow A1, A2, etc. and B1, B2, etc. Can you spell that out, please, and please do so completely
[/quote]

OK, so:

All surveypages should be presented in randomized order. However, A1 should never follow after participants saw A and the other way around, meaning: After A: A2, A3, A4, B, B1, B2, B3, B4 are allowed, only A1 is not allowed to follow A. Same for A1 with A; after A1: A2, A3, A4, B, B1, B2, B3, B4 are allowed, only A is not allowed to follow A1. Same with B and B1; after B; A, A1, A2, A3, A4, B2, B3, B4 are allowed, only B1 is not allowed to follow B. And the other way around: after B1: A, A1, A2, A3, A4, B2, B3, B4 are allowed, only B is not allowed to follow B1. All others should be randomized and there are no constraints to that. I hope, it makes more sense now.
[/quote]

Okay, thanks. Well, in principle, you'd do something like this:

<surveypage A>
/ ontrialbegin = [
values.do_not_select = surveypage.A1;
]
/ subcaption = "Wie wirkt diese Person auf Sie?"
/ subcaptionfontstyle = ("Arial", 2.5%, true, false, false, false, 5, 0)
/ showquestionnumbers = false
/ questions = [1=A; 2=negpos; 3=symp]
/ nextlabel = "Weiter"
/ nextbuttonposition = (47, 95)
/ showbackbutton=false
</surveypage>

<surveypage A1>
/ ontrialbegin = [
values.do_not_select = surveypage.A;
]
/ subcaption = "Wie wirkt diese Person auf Sie?"
/ subcaptionfontstyle = ("Arial", 2.5%, true, false, false, false, 5, 0)
/ showquestionnumbers = false
/ questions = [1=A1; 2=negpos; 3=symp]
/ nextlabel = "Weiter"
/ nextbuttonposition = (47, 95)
/ showbackbutton=false
</surveypage>

setting values.do_not_select to "" otherwise and using that as the /not constraint:

<list items>
/items = (surveypage.A surveypage.A1 surveypage.A2 surveypage.A3 surveypage.A4 surveypage.B surveypage.B1 surveypage.B2 surveypage.B3 surveypage.B4)
/ not = (values.do_not_select)
/ replace = false
/ selectionmode = random
</list>

You're going to run into a problem, though, because randomization happens on the fly: It's perfectly possible that for the last two trials only A and A1 (or B and B1) are left to be sampled in the list. Then the constraint has to be dropped and you'd get A followed by A1 (or vice versa). If you want to avoid that, you need to write an algorithm that constructs a valid sequence in advance and then just have the remainder of the script run that sequence.

Supreme for real!
Thanks! Again! :

2. If I run the survey as a block, I have to change the surveypages into trials and cannot use sliders anymore, right?
Thank you very much!
Best,

RE: Blank pages between randimized surveyspages and randomization with constraints

Hello everybody,

I have an explicit attitude questionnaire with one item-picture and three response scales on each page.
Now, I have two questions:

1. I would like the items to be presented in randimized order with certain constraints (e.g., B should never follow A, E should never be presented after D...). Is that possible? How?
2. Also, I would like to show blank pages between surveypages containing items. Is that possible? How?

Thank you very much in advance!
Best,
Ronja

Re. 1) Use a <list> with /not constraints to sample your items or pages.

Re. 2) Run your surveypages via <block> and from each surveypage you can /branch to a trial displaying a blank screen for the duration of your choice.
