Hi All,
Has anybody ever programmed a visual search task through Inquisit? Basically, I need to create 130 trials, each of which presents a 4x4 matrix of insect pictures, and participants are required to indicate whether there is an odd-one-out (e.g., spider among dragonflies). I have several different matrix types, and would like to be able to randomize which type of stimulus appears in each matrix slot, which stimulus from that type appears, and where each appears. Additionally, I would like to ensure that no picture appears twice in a single matrix. Obviously, I am trying to avoid creating 130 different matrices, saving as jpegs, and then randomizing their appearance. Just wondering if anybody has done anything similar and can offer some tips.
Thanks!
