GSR

GSR measures the conductivity of the skin. This varies with the level of arousal of the

autonomic nervous system. The GSR works by passing a minute amount of current through

the body (<10 micro Amps). Although in reality more complicated, it is easiest to think of the

GSR in terms of sweaty palms. When you are nervous or stressed your palms sweat. This

raises the conductivity of your skin (makes it easier for electricity to pass through it). When

you are calm you sweat less and hence are less conductive.

There are three choices from the GSR Menu: Graph, Meter and General Graph .

1. Graph displays the raw signal.

2. General Graph allows you to output the GSR as a general graph, a post session ASCII

output or a live DDE output.

3. Meter is a digital display of the GSR.
