Electrodermal Activity (EDA)
History (in French)
- Aux sources d'un marqueur neurophysiologique des émotions : l'activité électrodermale
(Going back to the sources of a neurophysiological marker of emotions : the electrodermal activity) - First papers being published about "galvanic reactions" of the skin:
- Féré, C. (1888) Note sur les modifications de la tension électrique dans le corps humain, Comptes Rendus de la Société de Biologie, pp. 28-33.
- Féré, C. (1888) Note sur les modifications de la resistance sous l'influence des excitations sensorielles et des émotions, Comptes Rendus de la Société de Biologie, pp. 217-219.

Skin Conductance Responses' scoring method with Acqknowledge
Analyses with Acqknowledge (native Biopac Software): Technical Report, 2nd version (2015): Selective Attention & Awareness Laboratory (SAAL) Behavioural Brain Sciences Centre, University of Birmingham, UK. and here
The following document describes a SCR scoring method used by different researchers at the CISA. (written by Y. Stussi). This method is acknowledged by many experts in the field and accepted in peer-reviewed publications (Stussi et al., 2015)
