Arousal
The degree of physiological and subjective activation, ranging from calm or sleepy to excited or agitated. Arousal is one of the two dimensions commonly used to describe affect, alongside valence, and it is indexed by self-report and by autonomic measures such as electrodermal activity and heart rate. A meta-analysis of anger management activities found that activities which decrease arousal reduced anger, whereas activities which increase arousal did not reliably do so. Controlled experiments on venting anger found that it keeps anger active and increases aggression. This note reviews the evidence, its limits, and the regulation strategies that reduce anger instead. 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. (2009). Measures of emotion: A review. doi:10.1080/02699930802204677 Supports the claims that measures tend to reflect dimensions rather than discrete states, converge only modestly, and that there is no gold-standard measure of emotion. Narrative review. (2024). A meta-analytic review of anger management activities that increase or decrease arousal: What fuels or douses rage?. doi:10.1016/j.cpr.2024.102414 Supports the claims that arousal-decreasing activities reduced anger and aggression and that arousal-increasing activities were ineffective overall. The arousal-increasing studies were heterogeneous, so conclusions about specific activities such as running are less certain. (2010). Autonomic nervous system activity in emotion: A review. doi:10.1016/j.biopsycho.2010.03.010 Reports considerable autonomic response specificity when emotion subtypes are considered. It is never cited as evidence against autonomic fingerprints; it is cited only as a partial counterpoint to Siegel et al. (2018), and claims citing both must say so.Where the site uses it
