Electrodermal Response refers to the electrical conductance of the skin in response to stimuli. The spelling of the word can be broken down phonetically using the IPA transcription system as /ɪˌlɛktrəʊˈdɜː(r)m(ə)l/ /rɪˈspɒns/, with emphasis on the second syllable of "electrodermal" and the first syllable of "response". The stress is marked with a diacritical mark (ˈ) and the schwa sound /ə/ indicates a slight and unstressed sound. Together, these elements form the correct spelling and pronunciation of the term.
Electrodermal Response refers to a physiological reaction of the skin that occurs in response to emotional or cognitive stimuli. Also known as the galvanic skin response (GSR) or skin conductance response (SCR), it is a measure of the electrical conductance of the skin caused by the activity of sweat glands.
The Electrodermal Response is controlled by the autonomic nervous system, specifically the sympathetic branch. When an individual experiences emotional or cognitive arousal, such as excitement, fear, or stress, their sympathetic nervous system is activated, leading to changes in the activity of sweat glands. This increased sweat gland activity leads to an increase in the skin's electrical conductance, which can be measured using electrodes placed on the surface of the skin.
The measurement of Electrodermal Response has been used extensively in psychological and physiological research as a non-invasive method to assess psychological and emotional states. It has been particularly useful in studying emotional responses, stress levels, and arousal.
Electrodermal Response is commonly utilized in areas such as psychology, neuroscience, and market research, where it can provide valuable insight into an individual's emotional and cognitive state in relation to external stimuli. By measuring changes in skin conductance, researchers can gain a better understanding of an individual's physiological response and subjective experience in various situations.
Overall, Electrodermal Response serves as a valuable tool for researchers and practitioners interested in understanding the relationship between emotional states, cognitive processes, and physiological responses.
The term "Electrodermal Response" is a combination of two words: "electro" and "dermal" with "response" functioning as a descriptive noun.
1. "Electro" comes from the Greek word "ēlektron", which means "amber". It is derived from the ancient Greeks' discovery that amber, when rubbed with fur, produced a static charge that could attract certain objects. Over time, "ēlektron" came to represent "electricity" or "electrical charge".
2. "Dermal" originates from the Greek word "derma", meaning "skin". It refers to the outer layer of the skin or the integumentary system.
3. "Response" comes from the Latin word "respondere", which means "to answer" or "to reply". In this context, it indicates a reaction or output to a stimuli or input.
