Psychophysiology - Measuring bodily activity - electrodermal activity
3 important questions on Psychophysiology - Measuring bodily activity - electrodermal activity
What does electrodermal activity measure?
Sweat glands of ski (skin conductance)
What are the two types of sweat glands?
- Apocrine: scents & pheromones (open in hier follicles, found in armpits and genital areas)
- Eccrine: thermoregulation (most dense in hand palms and soles of feet)
What are the strengths and limitations of skin conductance?
Strengths:
Limitations:
- direct measurement of automatic nervous system
- very useful
Limitations:
- bad temporal resolution (takes 30sec for effect to show and go back to basic)
- very sensitive to noise
