Understanding EDA data
- What is Electrodermal Activity (EDA)?
- How is EDA measured?
- Is EDA the same as GSR?
- What does a high level mean? A low level?
- Does EDA change with temperature?
- What are tonic and phasic changes?
- What is a SCR?
- Why bother to measure both left and right? Shouldn’t the two sides be the same?
- Can I measure multiple areas at once?
FAQs
