You need to add one or several <picture> elements to the script.

<picture face>
/ items = faceitems
....
</picture>

<item faceitems>
/ 1 = "fear_01.jpg"
/ 2 = "fear_02.jpg"
...
/ 11 = "happy_01.jpg"
...
/ 21 = "neutral_01.jpg"
...
/ 31 = "anger_01.jpg"
...
/ 40 = "anger_10.jpg"
</item>

You can then display that <picture> for the desired amount of time by adding it to <trial init>'s /stimulustimes:

<trial init>
...
/ stimulustimes = [0=blank, face]
/ response = noresponse
...
/ branch = [trial.choice]
/ recorddata = true
/ trialduration = 2000

</trial>

I am new to Inquisit and was wanting to use BART task for an upcoming study. However, I wanted to add images of faces before each new balloon.

I have 4 conditions (fear, happy, neutral, anger) and 10 images per condition -- changing the default # of balloons to 40 (which I can do easily)

My main question is how I would edit the script so that before each balloon, an image would appear for 2 seconds? I wanted it to choose randomly with no replacement per emotion condition.

In summation, if someone could offer advice on how to edit BART script to add pictures before each balloon that'd be great!
