Skin conductance refers to the level of electrical conductivity on the surface of our skin. It is an indication of how our body responds to certain stimuli, such as stress or excitement. When we feel stressed or excited, our sweat glands become active, increasing the moisture on our skin. This leads to a change in the electrical conductivity, which can be measured using electrodes. By studying
skin conductance, we can understand and monitor our body's reactions to different situations.

For reasons the researchers can not explain,
skin conductance levels in the typically developing children rose during the session with the guinea pigs.
For the current study, Dr. O'Haire and her colleagues
measured skin conductance, the ease at which an unnoticeable electric charge passes through a patch of skin, in children with ASDs and in typically developing children.
Each participant was shown threatening images, such as a bloody face interspersed with innocuous pictures of things such as bunnies, and rise
in skin conductance in response to the shocking image was measured.
For the first few minutes, the children read a book silently, giving researchers a baseline measure of
skin conductance while carrying out a non-stressful, familiar task.
Researchers have compared such things as increase of heart rate, blood pressure and
skin conductance when men and women are confronted with a crying or smiling baby.
Skin conductance rose in step with the apparent level of threat, just as it does when a person faces a genuine possibility of physical harm.
So as not to be influenced by patients» discourse and analysis of their eating disorders, the researchers used a «
skin conductance test,» which measures the subject's sweating rate when exposed to various images.
The researchers found that, compared to the typically developing children, the children with autism had
higher skin conductance levels when reading silently, reading aloud, and in the group toy session.
Texas A&M researcher Roger Ulrich, for instance, has shown that people who watch a calming nature video after a stressful experience have markedly lower muscle tension, pulse, and
skin conductance activity after less than five minutes.
The instrumentalists receive a wrist band
with skin conductance sensors that can in a sense measure the musician's emotional state.
A number of neurobiological markers (e.g., lower heart rate and
skin conductance reactivity; reduced basal cortisol reactivity; abnormalities in the pre - frontal cortex and amygdala) have been associated with oppositional defiant disorder.
The research utilizes the still - face and other stress paradigms and multiple measures including ERP and EEG, salivary cortisol and alpha amylaze, and
skin conductance as well as behavior.
At the same time, researchers were tracking the mothers» and babies» arousal responses, measured
through skin conductance and behavior.
When the session with the guinea pigs began, however,
skin conductance levels among the children with ASDs dropped significantly.
Subjects who had expressed a high level of support for policies «protecting the social unit» showed a much larger change
in skin conductance in response to alarming photos than those who didn't support such policies.
For The Revenant screenings, audience members wore wristbands that measured physiological responses — heart rate variability,
skin conductance (sweat, basically), body temperature, movement, and noise — throughout the film.
Results indicate unforgiving feelings encouraged more aversive emotion, significantly higher electromyogram (EMG),
skin conductance, heart rate and blood pressure.
Berman (1980) studied the arousal patterns in men and women when they were confronted with a crying or smiling baby measuring such things as increase of heart rate, blood pressure and
skin conductance.
Mobbs measured
the skin conductance of his players by rigging them up to a device similar to a lie detector.
Automobile taillights designed as two concentric disks elicit much stronger physiological arousal (
skin conductance, pupil dilation) than other taillight patterns.
Traditional methods of lie detection include face - to - face interviews and polygraphs that measure heart rate and
skin conductance.
As the participants played this painful game, de Berker and his colleagues monitored
their skin conductance and pupil size — measures of physical stress.
(Self - reported mood ratings were confirmed by measures of heart rate and
skin conductance.)
Any effects were assessed using a survey and changes to the volunteers»
skin conductance, a measure of physiological arousal.
«That allows us to measure
skin conductance, body temperature and variations in heart rate that change, for instance, when someone is startled,» explains Dr. Bernd Resch.
And disparities in physiological reactions, such as brain waves or
skin conductance, could be similarly attributable to differences in mood or thoughts over time, according to University of Arizona psychologists John J. B. Allen and Hallam L. Movius.
The other path was to study fear learning — simple associations that are expressed physiologically through a bodily response such as a change in heart rate,
skin conductance, arousal or pupil dilation.
Any effects were assessed by recording changes to the volunteers»
skin conductance — a measure of physiological arousal — and using a post-experiment questionnaire.
Proponents of the idea of multiple personalities have also performed controlled studies of biological differences among alters, revealing that they may differ in respiration rate, brain - wave patterns and
skin conductance, the last being an accepted measure of arousal.
This measured
skin conductance, a measure of physiological arousal, and reaction time of the participant.
The researchers measured physiological vital signs like body temperature,
skin conductance, ear pulse, blood pressure, respiratory function and cardiac rate throughout the experiment.
Your temperature and
skin conductance can also reveal secrets about your emotional state, and Picard can tap them with a glove - like device called the Q Sensor.
I got a taste of how it can feel to have my most private thoughts exposed when I slipped on one of Picard's Q Sensor gloves to measure
my skin conductance.
During listening,
the skin conductance was measured with sensors attached in the listeners» fingers in order to record the magnitude of the emotional reactions to different acoustic conditions.
fMRI is generally thought to be no more or less reliable than the traditional polygraph test, which measures the changes in various physiological parameters — such as heart rate, blood pressure and
skin conductance — that can change when someone is lying.
Since then, biofeedback is often associated with the use of electronic monitoring, such as EMG, EEG,
skin conductance and temperature.
Although the wristbands used in the study have the look of a fitness tracker, the key difference is their ability to measure
skin conductance (sweating response).
Measurements of temperature, heart rate, movement and
skin conductance were collected using Empatica E3 wristbands.
We also aim to determine whether this new measure is sensitive to second - to - second changes in children's physiological arousal (e.g.,
skin conductance, heart rate, movement), as measured using a wearable but non-intrusive autonomic sensing device.
Skin conductance response was reduced in athletes and absent in quadriplegics, and both groups had greater heart rate deceleration than controls.
Methods: We measured both physiological (event - related potentials,
skin conductance, heart rate) and subjective responses (valence and arousal ratings) to stimuli from the International Affective Picture System.
