Sara, et al

this might sound unlikely- but go to a site on autism and clinical literature on educating autism spectrum disordered- they have to be taught to read faces like they are road maps in order to interpret and translate feeling implied in facial expression. Really not that far removed or unlike the limited resources for emotional intelligence that are the parts themselves.

These sites may have the illustrations and eplanations that youre looking for. I have 2 autistic nephews and keep up on the literature when I am able.
