Skin Conductance Response Flashcards

1
Q

What happens in a skin conductance test?

A

Electrodes are attached to the index and middle fingers of one hand. A tiny current is applied to the electrodes to measure how much electricity is being conducted. Individuals who are stressed have a higher SCR

Q

Why is sweat used in a SCR?

A

When we experience stress, it activates a fight or flight response. One of the consequences of this is that we sweat more and this can be detected by our hands

Q

What are two strengths or a SCR?

A
  • it has practical applications so can achieve healthier stress levels
  • takes into account that different people have different patterns of skin conductance which is why a baseline is taken to compare it to

Q

What are two limitations of SCR?

A
  • failure to take into account these difference between participants threatens the validity of research studies using SCRs to measure stress
  • affected by external factors such as temp and humidity or internal factors such as medication and alcohol which can then lead to inconsistent readings
