Hi,
I am trying to create an experiment in which participants will go through 8 trials in which they rate a photo and a statement which are presented together. I want to randomly present 4 control and 4 experimental statements, paired with photos of either black (out of a pool of 12 pictures) or white individuals (also out of a pool of 12). Ultimately, participants will have seen (in some random order):
Ctrl + White 
Ctrl + White
Ctrl + Black
Ctrl + Black
Exp + White
Exp + White
Exp + Black
Exp + Black
I am very new to Inquisit, and am a little confused on how to create conditions to ensure that the photo and statement are randomized, but conditionally. Any help on how to create something that performs this function is greatly appreciated. Thank you!

I don't see where or why you need any conditional randomization for the procedure you described. It's implementable using just the most basic syntax constructs covered in the tutorials ( https://www.millisecond.com/support/docs/v6/html/tutorials/tutorials.htm )

Hi Dave, thanks so much for your response. This certainly clears up my randomization issues. I was wondering how I can include a bunch of questions on the same page as the stimuli pair. I tried changing the likert items to trials and adding all my questions, but that hasn't worked. I am trying to create something along the lines of:

<element>
/ stimulusframes = [1=white_individual, ctrl_statement] 
/questions = [1 = Q1, 2 = Q2,...., 7 = Q7]
</element>

My questions look something like this:

<radiobuttons Perceived_Prejudice3>
/ caption = "How likely do you think this person is prejudiced against sexual minorities?"
/ options = ("Extremely likely", "Likely", "Somewhat likely", "Neither likely nor unlikely", "Somewhat unlikely", "Unlikely", "Extremely likely")
/ optionvalues = ("1", "2", "3", "4", "5", "6", "7")
/ order = sequence
/ position = (75%, 50%)
/ orientation = horizontalequal
</radiobuttons>

I also tried to create a surveypage of the questions, but I am not sure how to ensure that all 7 questions are displayed on the same screen as the stimuli pair, for every single trial.

Thanks again for your help!

Thanks so much for your help!

I have one more question regarding survey pages -- if I wanted to present the questions over two survey pages, how do I ensure that the stimuli are displayed on both pages?
