[open] Multiple stimuli at once

njmedeir

First of all, our lab is very excited about your product!

Second, we are trying to design a visual search experiment in which a grid of varying sizes (4x4, 6x6, 8x8, etc) would contain 1 target (a "F" facing left or right) and the remaining stimuli would be distractors. I think we've figured out how to load the images, but I was wondering if you had any suggestions about how to generate this grid (maybe using a function?) and display multiple images side by side (in various arrays on the screen...4x4, 6x6, etc).

Any guidance would be greatly appreciated!

As it happens, @lvanderlinden posted an experiment pretty much like that (I think) in the discussion below. I would take a look at this experiment and post further questions (if any) in that discussion.
