Hi, I am new to Inquisit and am having a bit of trouble getting started. I am after a Visual Search task, however can not find something similar in the Millisecond test library. The visual search design I am after involves a search screen with pictures (i.e red/blue squares/trianges) randomly arranged on the screen. Participants are asked to indicate as fast as possible whether a target picture is or is not present. Any help would be greatly appreciated!
Thanks!

The Visual Search Task available at https://www.millisecond.com/download/library/VisualSearch/ should actually fit pretty closely:
"After the presentation of one of three cue types (happy, fearful, neutral) participants are presented a search screen with 3, 6 or 9 pictures randomly arranged in a circle and are asked to indicate as fast as possible whether a target picture (e.g. picture of a house) is present or not."
You would only need to adapt the latter part, of course (your design doesn't involve any cues).

Thanks for your quick reply!
The visual search task from the millisecond test library has coordinates of 9 possible pictures that circle equally spaced around the
center of the screen. How do I change the expression so that the pictures are spaced more randomly?
Thanks

You set up <list>s that have more coordinate pairs and sample from those randomly instead. Depending on your needs, you can pull other tricks in addition, such as off-setting those coordinates by randomly varying amounts.
See e.g. https://www.millisecond.com/forums/FindPost17247.aspx for an example.
