Presenting same stimuli in different random order

dakotadd

Hello,

I am trying to present the participants with 10 set images presented in a random order. in the next trial they will be presented with the same 10 images in a different random order. I would like all 10 images on the same screen, not presented 1 by 1. I am not sure how to achieve this using the sketchpad? If anyone has advice I would greatly appreciate it.

Also, I had the idea of making an array of these 10 stimuli, shuffling them randomly and assigning the corresponding image to the first item of the array, then the second item of the array etc. I'm not sure if this makes sense or how it would work? again I could really use some guidance on this.

Thanks a lot!

Hi @dakotadd,

I imagine you mean that you want to present the images in random locations (as opposed to a random "order", since you then specify that all images should be presented at the same time).

If you're using a fixed set of locations, the simplest method is that proposed by @sebastiaan in this thread:

https://forum.cogsci.nl/discussion/5892/show-multiple-images-at-the-same-time-at-random-positions

You'd just need to adapt it to your specific needs. This is actually simpler than defining an array, shuffling it and than sampling it (though if you wanted to go down that route, you could do it using either Python or Javascript).

Hope this helps.

Fabrice.
