stimuli presentation in sequence from a generated list

nrouhani — Mon, 25 Sep 2017 11:55:58 GMT

hello!

at the beginning of my experiment, i am populating a list of stimuli (randomly selected from sub-pools of different kinds of stimuli, designated by their corresponding item numbers on a full stimuli list, like so: https://www.millisecond.com/forums/Topic21763.aspx#bm21766 ) that i would like to then be shown in order. I see that my list (list.OldStims.items) is being correctly populated with the item numbers that should be used to select from the "allItems" list of stimuli, but the items are not being presented in the order that I have appended them. how would i be able to do this? thank you!

A list's default behavior is random selection without replacement. If you wish to sample list items sequentially, specify /selectionmode = sequence:

<list oldStims>
/ selectionmode = sequence
</list>
