Affective norms and e-index
For each word, the emotional intensity indicator is calculated based on the maximum physiological activation (Arousal) observed in the subject, using the emotional norms defined for each language.
Emotional norms were established in several languages in the late 1980s. These analyses were carried out and standardized on the 3 dimensions of Valence, Physiological Activation and Dominance using the Self-Assessment Manikin (SAM) methodology.
The precise methodology was initially defined and described for the English language to build a standard called ANEW (Affective norms on English Words) and has been reproduced in other languages (FAN = French Affective Norms, ANGST = Affective norms for German Sentiment terms).
L'activation physiologique est parfois nommée 'niveau d'excitation' (arousal en anglais) par certains chercheurs en psychologie cognitive.
