  • Randomising pictures in an event list

    Hello,

    I am wanting to know whether it is possible to randomise the presentation of pictures contained within an event list. I have five different trial types, that consist first of an instruction screen, and are then all linked to a list of stimulus pictures (to which participants respond using two different keys). The list contains 420 pictures, and I want each participant to see each image once in random order.

    Is there a way to randomise the presentation of the stimuli within his list?

    Thanks in advance.

    Yes, this is possible. You would randomize under the Block level, under the Randomization tab that the stimulus list is attached to. Then click on the "Randomize the trials in this block" option.
