Go back to Analysis → Electrodermal activity → Construct phasic EDA from tonic
If you see the following error, you need to adjust the threshold:
Adjust the Measurements pane as follows:
Click the down-arrow to the left of the measurements, select Preferences → Measurements → change the numbers to 3 rows by 5 columns.
When you select Event amplitude, the following window pops up. We select “Amplitude at first event only”.
When you select Event count, select where you want to look for the events and select your EDA channel that contains the water droplet markers.
Once your measurement list is complete, click the down-arrow again and then New Preset. You can name your measurement preset and use it easily for each subject.
Next, we export all these measurements for each SCR into an excel spreadsheet.
Analysis → Find cycle
Tab Cycles/Peaks: Select Events
Start event: Notes → Waveform onset on your EDA channel
End event: EDA → Skin conductance response; located on EDA channel
Selection tab:
Starting event: -3
Ending event -1
Adjust if necessary; you want the onset of the EDA response (i.e. the dips before each rise) to be included in the selection (blue range).
Output tab: check “Save measurements into Excel spreadsheet file” and click “Find all in Focus Areas”.
The output looks as follows:
