Assign a color to a stimulus
I'm actually designing a visual search experiment. I'm a beginner with all of this. In my experiment I have two stimuli. On a sketchpad I've wrote [stim1] and [stim2] and then I've defined the factorial plan (4X4) in the block loop. I've used "shuffle_horiz stim1 stim2" in the script to randomize the location.
This is where it becomes more tricky for me. I want [stim2] to be in red or have a different size than [stim1]. When I change the color of [stim2] on the sketchpad, the color isn't assign to [stim2] but rather to the location of it. So [stim1] is red when it is at the location of [stim2]. Is there a way to assign the color only to [stim2] ?
The same is true for the size....It is assigned to the location rather than to [stim2]..
Thank you for your help,
