Good afternoon,
I am very new to Inquisit, with programming experience in other languages (Matlab, a bit of JS and Python). I have to program an emotion-induced blindness task, and have been adapting some code that I was given by a collaborator.
Each trial in the task consists in
1- A rapid visual stream of images, that are drawn from a bunch of Filler images, one Distractor, and one Target, which can be drawn from
Familiar or
Unfamiliar items.
These are defined like this:
<item fillers>
/1="scene35.jpg"
/2="scene36.jpg"
/3="scene37.jpg"
...
</item>
<item famtargetsitems>
/1="FamScene1.jpg"
/2="FamScene2.jpg"
/3="FamScene3.jpg"
...
</item> etc.. for the distractors
<picture f1>
/items = fillers
/select = noreplace
</picture>
<picture f2>
/items = fillers
/select = noreplace
</picture>
...
<picture famtargets>
/items = famtargetsitems
/select = replace
</picture>
This step seems to work fine.
Then step 2- I would like to have 9 images displayed at once (in a 3 x 3 array), and these need to include:
- 3 fillers that were present in the stream (but chosen randomly)
- 3 Familiar targets (including the one target present in the stream, if they were in the Familiar condition)
- 3 Unfamiliar targets (including the one target present in the stream, if they were in the Unfamiliar condition).
I'm not sure where to start, as there are many things that need to be coded:
1) I would need to have some sort of object that includes all the filler images that were presented in the stream, from which I can randomly draw 3, and draw these at any of the random location on my 3x3 array.
2) I would need to pick from the unselected Familiar and Unfamiliar targets, again at random and draw them at the random locations in the 3x3 array.
I'm sorry this is such a complex thing (or maybe it's simpler than it looks to me!)
Thank you so much in advance for any help that you may provide, I'm grateful for this forum that has already helped me a bunch!
