Research note 01
A short history of the concept of catharsis from Aristotle's Poetics through Breuer and Freud's cathartic method to empirical research on emotional expression, with the working definition used by this project.
Research note 05
Affective computing promises to infer emotion as if it were a system metric. The evidence on facial movements and autonomic signals, together with questions of consent, explains why every metric in this artifact is an artistic value.
Question 11
Instruments record faces, heart rhythms and skin conductance. Emotions are inferred from those recordings, and the syntheses show the inference is weak: no gold standard, no autonomic fingerprint, modest coherence.
