Physical Contact Responses In Long Term High Strain Individuals
Sustained allostatic load alters autonomic gating, turning coregulative tactile input into sensory startle responses that increase metabolic regulation costs.
skin conductance response
Meaning
Electrodermal activity measures the changes in the electrical properties of the skin caused by the secretion of sweat from eccrine glands. The skin conductance response acts as an objective marker of sympathetic nervous system activation in the presence of emotional or cognitive stimuli. It provides a window into the level of physiological arousal a person is experiencing.
Arousal Tracking
Small fluctuations in sweat production occur milliseconds after a stimulus is perceived. Monitoring the skin conductance response allows for the detection of stress triggers that may not be consciously noticed by the individual. This tracking reveals the hidden costs of specific environments or interactions.
Stimulus Detection
Sensitivity to the environment is reflected in the amplitude and frequency of these responses. A person with a high baseline level of stress might show a skin conductance response to even neutral sounds. This constant activation indicates that the system is on high alert, which consumes metabolic resources.
The cost is a reduction in the attention span available for complex tasks. It also points to a thinning of the protective layer between the person and the world.
Measurement Reliability
Environmental factors like temperature and humidity must be controlled to get accurate data. Without these controls, the skin conductance response may reflect the room more than the person.
