Overview of extracted parameters from the EDA responses that were used in the data analyses.
| Parameter | Description | Unit |
|---|---|---|
| SCR_Amp | Amplitude of the skin conductance response | μS |
| SPR_Amp | Amplitude of the skin potential response | mV |
| SSR_Amp | Amplitude of the skin susceptance response | μS |
| SPRET | Turning point of the SPR relative to the SCR peak | % |
| SCR_Trise | Time from onset of SCR to peak SCR | sec. |
