<p><strong>How much is the delay in electrodermal response</strong>? i.e., the time it takes before which an electrodermal response can be realized. Basically I want to calculate the rate or frequency at which the measurements should be taken without missing any relevant data.</p>

<p>Can someone please answer or give pointers to some article. </p>

_What_ is the delay, or _how long_ is the delay? I'm not certain what you are exactly interested in.

"How long" is what I'm interested in knowing. Basically I want to calculate the rate or frequency at which the measurements should be taken without missing any response data.

The answer to your question regard to the EDA is getting a base level for responses from a candidate. The only way to measure this correctly is in to match body temperature and climate to the test subject but there must be no brain activity or any environental changes and zero atmosphere.
Zero gravity and a non oxygen environment don't work but body frequency levels will help to check brain activity levels as a guide

# Frequency at which electrodermal response should be measured

(Asked by: username_0 on 2013-09-19)

I'm computer science graduate working on a health monitoring device.

**How much is the delay in electrodermal response**? i.e., the time it takes before which an electrodermal response can be realized. Basically I want to calculate the rate or frequency at which the measurements should be taken without missing any relevant data.

Can someone please answer or give pointers to some article.
