GSR
Noun A physiological response, specifically a change in the electrical properties of the skin, such as its resistance or the generation of weak currents, that occurs as an involuntary reaction to emotional or psychological stimuli like stress, anxiety, arousal, or fear.
The term gsr is a technical abbreviation used primarily in scientific, medical, and psychological contexts. It refers to a measurable bodily signal. * The polygraph test monitors several indicators, including gsr, to assess a subject's truthfulness. * Researchers recorded the participant's gsr while they viewed emotionally charged images. * A sudden spike in gsr can be correlated with a startle response.
- Galvanic Skin Response: This is the full term for which gsr is the acronym. It is often used interchangeably but is more formal.
- The study measured Galvanic Skin Response as an objective indicator of emotional engagement.
- Electrodermal Activity (EDA): This is a more modern and comprehensive term that encompasses gsr. EDA is now the preferred term in much scientific literature.
- The wearable device tracks electrodermal activity to monitor stress levels.
- Galvanic Skin Response (n): The full term for GSR.
- Electrodermal Activity (EDA) (n): A contemporary synonym often used in research.
- Psychogalvanic Reflex (n): An older, less common term with the same meaning.
- Skin Conductance (n): A related measurement focusing on the skin's ability to conduct electricity, which changes during a GSR event.
- Electrodermal response
- Skin conductance response
- Psychogalvanic response
The core meaning of gsr is a change in the skin's electrical state due to autonomic nervous system activity. It is not the emotion itself (e.g., stress), but a physical correlate or symptom of it. The measurement of this change is a key tool in: * Lie Detection: As part of polygraph tests. * Psychological Research: To study emotional reactions, attention, and cognitive load. * Human-Computer Interaction: To gauge user engagement or frustration. * Biofeedback Therapy: To help individuals learn to control stress responses.
- a change in the electrical properties of the skin in response to stress or anxiety; can be measured either by recording the electrical resistance of the skin or by recording weak currents generated by the body
