iMotions Software Module

EDA/GSR (Electrodermal Activity)

Measure skin conductivity to indicate emotional arousal and stress.

Measure emotional arousal through skin conductivity

Electrodermal activity (EDA, also known as galvanic skin response; GSR) measures the activity of the autonomic nervous system. Our level of emotional arousal changes in response to the environment we’re in – if something is scary, threatening, joyful, or otherwise emotionally relevant, then the subsequent change in emotional response that we experience also increases eccrine sweat gland activity. EDA / GSR serves as a valuable index of emotional arousal as it offers insights into a respondent’s underlying physiological and psychological processes.

Automated EDA/GSR analyses

Quantifying moments of increased physiological arousal allows you to better understand the impact of stimuli. Through our open-source R Notebooks, iMotions provides automatic EDA peak detection, as well as epoching and aggregates of binned data, helping you to fully evaluate the effect of the stimulus.

Quickly and easily assess emotional intensity

Researchers are already using the EDA/GSR module to:

  • Measure cognitive load in education
  • Investigate food craving regulation
  • Explore player experience in VR games
  • Investigate the effects of sleep deprivation
  • And more
