How to set item/stimulus frequency

By Cutshak - 2/13/2014

I am trying to create a go/no go task where I can manipulate the frequency of an item or stimuli appearing in percent. I have a premade script that selects the items at random but I am trying to change that. Any help would be greatly appreciated.

Your description doesn't really paint a clear picture of what exactly you want to do. However, for starters, I recommend you take a look at using <list> elements for stimulus selection, particularly utilizing the /itemprobabilities attribute. Details and examples can be found in the documentation for said attribute.
