Context
In inference about emotion, the situation, culture, relationship, bodily state and activity in which a signal occurs. The same facial configuration or change in heart rate can accompany different states in different contexts, so a signal considered without its context supports only weak conclusions. Reviews of facial movement and autonomic data identify context as one of the main sources of variation that simple signal-to-emotion mappings ignore. 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. The works the definition rests on, with the level of evidence each was appraised at. (2019). Emotional expressions reconsidered: Challenges to inferring emotion from human facial movements. doi:10.1177/1529100619832930 Supports the claim that facial configurations are not reliable, specific indicators of emotional states across cultures, situations and people, although they co-occur above chance. A narrative review by authors associated with one theoretical position; critics dispute parts of it. (2018). Emotion fingerprints or emotion populations? A meta-analytic investigation of autonomic features of emotion categories. doi:10.1037/bul0000128 Supports the claim that autonomic effect-size patterns did not clearly distinguish one emotion category from another and varied substantially within categories. Laboratory inductions; the interpretation favours one theory of emotion.Where the site uses it
