carmen0101 - 4/9/2020

Is it possible to set 12 image locations on a trial screen and then for the images to be randomly drawn from a pool of 50 images (e.g. my items WF_001 below).

I would also like the mean of the images randomly drawn out to be between 10-40 (e.g. image items: 5,2,5,40,41,9,11,45,50,7,26,25 = mean of 22.17)

I am hoping to achieve something visually ike this:

Yes, this is certainly possible. What about this is unclear to you?

> I would also like the mean of the images randomly drawn out to be between 10-40.

Put all item numbers in a <list>, /ontrialbegin, sample 12 items numbers from that list a put it in another list. Check that list's mean property. If the mean is not in the desired range, repeat the process.

<list allitems>
/ poolsize = 50

</list>

<list 12selecteditems>
/ selectionrate = always
</list>

<values>

</values>

<block example>
/ trials = [1-4 = select]
</block>

<trial select>
/ ontrialbegin = [
    values.success = false;
    list.allitems.reset();
    list.12selecteditems.reset();
    list.12selecteditems.appenditem(list.allitems.nextindex);

    list.12selecteditems.appenditem(list.allitems.nextindex);
    list.12selecteditems.appenditem(list.allitems.nextindex);
    if (list.12selecteditems.mean >= 10 && list.12selecteditems.mean <= 40) {
        values.success = true;
    };
]
/ branch = [
    if (values.success) {
        return trial.showselection;
    } else return trial.select;
]
/ trialduration = 0
/ recorddata = false
</trial>

<trial showselection>

Hi Dave, thank you for your advice. It gave me great start.

You use the list 12selecteditems in the picture elements' /select

Thanks Dave, that definitely helped! I am having trouble with the data values. I would like it so that when an alcohol images is shown, the data value to be recorded as 1 and is it if is a neutral drink to be recorded as 0. Following is the coding and right now regardless of the image randomly shown at 0ms, it is being recorded as drink =1. How do I change the if and else sectionf under the <trial>?

The bolded part is invalid syntax. It will not do anything.



You should not use selectionmodes in /stimulustimes.

<trial mixed1>
/stimulustimes = [0=noreplacenorepeat(picture.Neutraldrinks,picture.Alcoholdrinks);...]
...
</trial>

Instead either set up separate trials for neutral and alcohol, or -- if need be -- sample the picture element from a <list> and use insertstimulustime(). You can then sent the value of interest based on the list's current index.
