Q

Five steps to explain process

A
  1. Interviewer poses questions- explain to subject they will be asked questions.
  2. Subject psychologically interprets- tell subject to interpret questions and if they have any problems
  3. Physiological changes occur- breathing, cardio and EDA. Your brain works harder to lie
  4. Polygraph records changes
  5. Collected data is interpreted

A

Tracing

42
Q

4 types of tracing

A

Homeostasis- baseline
Tracing response- arousal to stimulus
