12 set positions for images from a pool to appear at

carmen0101 — Mon, 27 Apr 2020 10:52:11 GMT

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:

<item WF_001>

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.

RE: 12 set positions for images from a pool to appear at

[b]carmen0101 - 4/9/2020[/b]
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:

<item WF_001>
/1="morphs\WF_001_01.bmp"
/2="morphs\WF_001_02.bmp"
/3="morphs\WF_001_03.bmp"

/5="morphs\WF_001_05.bmp"

/8="morphs\WF_001_08.bmp"

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

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.
