It is so small and light that the test subjects can barely feel it. It takes measurements on one finger at a time<\/p>\n
Skin conductance, measured via a finger sensor, provides information about sweat gland activity. This value is closely linked to sympathetic arousal (such as that experienced during anxiety or stress). Tension therefore usually leads to an increase in skin conductance. This, along with finger temperature \u2013 which will be discussed shortly \u2013 is considered a good measure of tension and relaxation.<\/p>\n
Skin conductance is highly sensitive to psychological influences. It is often used to illustrate the principle of biofeedback and the influence of thoughts and emotions on the body. It is important to note when interpreting this data that there are no standard reference values for skin conductance; it must be considered on an individual basis and in terms of how it changes over time.<\/p>\n
One of the differences between skin conductance feedback and temperature feedback is that temperature reacts much more slowly (usually with a delay of 1\u20132 minutes). To generate warmth, clients can visualise warm stimuli (e.g. a campfire).<\/p>\n
It is not uncommon for temperature biofeedback to be combined with other methods in order to learn general relaxation techniques or, for example, to visualise the imagined warming process in autogenic training.<\/p>\n
