randomized set of scales on different pages

[strotter]

Hi – I’m trying to implement an experiment which current does not fully work as I’d like. After reading the critical sentence, I would like to show nine questions as scales in a specific manner: I want three scales/questions below each other (see below if it works out after posting) then a button “Next”. Then the same repeats on the second and third page. I would like to randomize the order of the nine scales on the three pages, which is the part that does not work. Is something like this possible?

Thanks for the help!

Hi,

Assuming you are not using Template, you can list the question+scale pairs in an array and shuffle it, then successively fetch the elements from the (shuffled) array in three different trials:

// array of functions that return a question+scale pair
SCALES = [
    ()=>[
        newText("question1", "Question 1").center().print(),
        newScale("scale1", 7).before(newText("low X1")).after(newText("high X1")).log().center().print()
    ],
    ()=>[
        newText("question2", "Question 2").center().print(),
        newScale("scale2", 7).before(newText("low X2")).after(newText("high X2")).log().center().print()
    ],
    ()=>[
        newText("question3", "Question 3").center().print(),
        newScale("scale3", 7).before(newText("low X3")).after(newText("high X3")).log().center().print()
    ],
    ()=>[
        newText("question4", "Question 4").center().print(),
        newScale("scale4", 7).before(newText("low X4")).after(newText("high X4")).log().center().print()
    ],
    ()=>[
        newText("question5", "Question 5").center().print(),
        newScale("scale1", 7).before(newText("low X5")).after(newText("high X5")).log().center().print()
    ],
    ()=>[
        newText("question6", "Question 6").center().print(),
        newScale("scale6", 7).before(newText("low X6")).after(newText("high X6")).log().center().print()
    ],
    // etc.
]

// shuffle the array
fisherYates(SCALES)

newTrial( "page1",
    ...SCALES[0](), // insert the commands returned by the function in the first entry of the array
    ...SCALES[1](), // insert the commands returned by the function in the second entry of the array
    ...SCALES[2](), // etc.
    newButton("Next").center().print().wait()
)
newTrial( "page2",
    ...SCALES[3](),
    ...SCALES[4](),
    ...SCALES[5](),
    newButton("Next").center().print().wait()
)
// etc.

This looks great! Thanks a lot!
In the current version I do use Template. But I’ll try around, this looks like a good starting point.
