Q
What are the 4 phases of examination?
A
- Pretest- most important sets the tone.
- Intest-
- Post test-
- Test data analysis-
8
Q
Five steps to explain process
A
- Interviewer poses questions- explain to subject they will be asked questions.
- Subject psychologically interprets- tell subject to interpret questions and if they have any problems
- Physiological changes occur- breathing, cardio and EDA. Your brain works harder to lie
- Polygraph records changes
- Collected data is interpreted

Tracing sensitivity
38
inflate the cardio to approximately ________ of pressure
60 mm to 70 mm, subjects with good blood pressure may be slightly lower, subjects with higher pressure slightly more.
39
When beginning, obtain ___________ of normal tracing average
30 seconds to one minute
40
Strive to maintain consistent 25 second ________.
Question pacing
41
Refers to the particular visual representation of the physiological data that is studied for its diagnostic value
Tracing
42
4 types of tracing
Homeostasis- baseline
Tracing response- arousal to stimulus
Tracing recovery-recovery from a tracing response
Artifact- distortion
43
To be considered a response to the question still ulus physiological arousal must occur within an anticipated amount of time from Sri ulus onset
Response
44
Tracing segments which show resulting evidence of a physiological, return to baseline e or homeostasis occurring as a compensatory action after a response artifact or any other form of excessive noise
recovery
45
A change in physiological pattern not attributed to an applied stimulus or from psychological, fear of detection of deception
Artifact
46
When to check if EDA is adjusted
When you put cuff, when you state is beginning
| And the first question
47
Conductance increases while ______ decreases
Resistance
48
Counter measures (Nelson)
Faking physiology
