Adding variables and defining variables
I am creating a facial perception task/experiment and am having issues with defining my variables and stimuli.
My experiment has: 2 IVS are race and emotion/expression.
I have four sets of images: (1) Neutral Asian; (2) Angry Asian (3) Neutral White (4) Angry White, which I have added to my file pool.
In my experiment, I want to show mages in pairs, each on a separate sketchpad so participants should see:
1) Neutral Asian and Neutral Asian
2) Angry Asian and Neutral Asian
3) Neutral White and Neutral White
4) Angry White and Neutral White
At the moment, the way the images are defined doesn't allow me to distinguish between the different races? Does anyone know what I am doing wrong?
Thanks for any help in this matter.
