Randomization in IAT

    Randomization in IAT

    Hello, is it possible to randomize the items so that they are not repeated, but the whole list used only once? Thank you

    Yes - You'll want to follow up on DirectRT's 'stimlist' feature.
    See the following link for more information: http://www.empirisoft.com/directrt/help/directrt_samples_stimlists.htm

    An excerpt from the DirectRT help manual:
    This time, we use the $ symbol. This again tells
    DirectRT we're using StimList, but that we want the stimuli selected randomly without
    replacement. DirectRT will make sure all of the stimuli are used before it re-randomizes the
    file and starts over.
