I think these symptoms of cognition cues is relevant yo many serious mental health conditions like bpd and autism As someone eith bpd I've got very intermittent psychosis symptons

The "other race effect" being brought up is very telling: the construct of social cognition is rather muddled from the outset starting from the vague definition utilizing "social cues" and "emotions" as units of analysis is simplistic - social skills (social persuasion and negotiation?) are on balance a matter of "expertise" and in-the-moment global processing using contextual and situational knowledge. There's a huge literature on affective processing with an actual biological basis - cf. Tomkins, et. al. The development and formalization of "script theory" and "frame theory" in both sociology and cognitive science in latter part of the 20th century was an attempt to reason about how social interaction actually plays out in the real world and it is obviously very dynamic but also for the most part structured as a 'game' and is far from spontaneous. Presumably investigators could just as easily have schizophrenic and normal controls interact with ELIZA in GNU Emacs and put them in an MRI machine and hypothesize about differential activation in different areas of the brain.
