Hi,
We are trying to write the code for a study, but we don't know how to realize our design (see below) in an appropriate way (i.e., without having to manually write all possible combinations which could be numerous). Any suggestion/comment/help is very much appreciated!
The design:
We have 4 types of stimuli, say A, B, C, and D. Each type contains 20 different pictures;
We also generated lots of different random locations (x, y combinations) that we want these pictures to appear on;
For each trial, we want to display certain numbers of total pictures (like from 10 to 20; to simplify this, we can also fix it to 14)--but can Inquisit realize the former way?
So N (A) + N (B) + N (C) + N (D) = 14, but these 4 numbers can be any possible combination that adds up to 14
Also, pictures selected (in each type) should be different; locations selected (across all types) should be different from each other
We are wondering whether we can realize this design in Inquisit 5 and how to do it. Thank you very much!
Best,
Kate
