Dear Community,

I am struggling with an implementation, and I am yet to find a solution by myself or in this forum. I want to assign different items to a stimulus element (sound and picture) depending on earlier selections (the participants have to enter their language and gender by dropdown). I would love to do this via an expression, but have not yet found a satisfying solution. Creating an empty <item> and filling it with .appenditem is not an option since this would be to much code.
I created a mock experiment to visualize, what I want to do. Maybe someone has a clean solution. The crucial part is the / ontrialend expression in the select-<trial>

<defaults>
/ inputdevice = keyboard
</defaults>

<item a>
/ 1 = "first"
/ 2 = "choice"
</item>

<item b>
/ 1 = "second"
/ 2 = "select"
</item>

<text instruction>
/ items = ("Press 'a' for the first items, press 'b' for the second items")
</text>

<trial select>
/ stimulusframes = [1 = instruction]
/ correctresponse = (30, 48)
/ ontrialend = [
    if (trial.select.response == 30) {
        text.continue.items = item.a;
    } else if (trial.select.response == 48) {
        text.continue.items = item.b;
    } else {
        text.continue.items = "ERROR";
    }
]
</trial>

<text dynamical>
/ select = sequence
</text>

<text continue>
/ items = ("Press SPACE to continue")
/ vposition = 80%
</text>


<trial showtext>
/ stimulusframes = [1 = dynamical; 2 = continue]
/ validresponse = (57)
</trial>

<block showblock>
/ trials = [1 = select; 2-3 = showtext]
</block>

Thank you in advance. Best,
Daniel

Thanks Dave,

I considered this, but since the script I'm working with was written by someone else who already did a lot of work which I just wanted to optimize, this is sadly not a viable (in terms of time investment) solution.

So there is no way to dynamically assign an <item> element to the / items attribute of a stimulus?

Thank you anyways. Best,
Daniel
