TDA Definitions

Question 1

What is PDD examination?

Answer 1

A process that encompasses all activities that take place between a PDD examiner and an examinee.

Question 2

Polygraph series

Answer 2

A collection of PDD charts wherein reviewed operational test questions have been presented to an examinee the minimum number of times required by a testing format.

Question 3

Polygraph chart

Answer 3

A graphic representation containing selected physiological data generated by an examinee during the data collection phase of a PDD examination.

Question 4

Channel/Waveform/Tracing

Answer 4

Refers to any one of the four sensor inputs used to monitor and record activityof the respiratory, EDA and CN system.

Question 5

Question string

Answer 5

All of the questions that appear om a polygraph chart between test commencement (x) and test termination (XX)

Question 6

Relevant Question

Answer 6

Pertain directly to the matter under investigation or to the issue being tested.

Question 7

Comparison question

Answer 7

Designated to produce a physiological response. The physiological responses are compared to RQ responses.

Question 8

Irrelevant questions

Answer 8

A non-emotion invoking question used to absorb orienting responses and assist in establishing the examinee’s phyisiological baseline.
* Neutral

Question 9

Stimulus onset

Answer 9

Verbal- when the examiner starts asking the question

Question 10

Stimulus end

Answer 10

Ending of the question

Question 11

Response

Answer 11

Physiological arousal to an applied stimulus.
*to be considered response- the physio arousal must occur within an anticipated amount of time from stimulus onset

Question 12

Response onset

Answer 12

Physiological change by examinee as a result of an applied stimulus
(asking the question)

Question 13

Response onset window (ROW)

Answer 13

Traditional time period where one would predict a physiological response to occur in order for that response to be deemed timely. (Timely response)

Question 14

Homeostasis

Answer 14

Complex interactive regulatory system by which the body strives to maintain a relative state of internal equilibrium.

Question 15

Test formats

Answer 15

Specific issue:
ZTC
MGQT
Screening:
DLCT
TES
LEPET
R/I

Question 16

Analysis Spot

Answer 16

An analysis spot consists of a relevant question and the applicable comparison questions used in the scoring process.

Question 17

Spot analysis

Answer 17

A produce wherein each tracing on a PDD chart is evaluated.
The response of a RQ is compared to the response of a CQ and values are assigned.

Question 18

Diagnostic features

Answer 18

EDA — 1 Primary
— 2 Secondary
CV —1 Primary
—2 Secondary
PN —6 features

Question 19

Latency

Answer 19

Period of time from stimulus onset to response onset. May differ based on channel, type of q. , individual.

Question 20

Duration

Answer 20

Amount of time that elapses from response onset to when the response returns to the pre-stimulus tonic level or establishes a new tonic level in the EDA or CV tracing, or recovery in the PN tracing.

Question 21

Artifact

Answer 21

A change in physiological pattern not attributable to an applied stimulus or recovery (i.e. cought, yawn, sneeze, sniff).

Question 22

Recovery

Answer 22

A duration in any tracing attributable to a physiological phenomenon occurring as a compensatory action after a response, artifact, or any other form of excessive noise.

Question 23

Excessive noise

Answer 23

Physiological tracing that reaches a level that disrupts or prevents the data from being used for TDA purposes.

Question 24

Law of initial values

Answer 24

The extent to which an individual is able to respond to physiologically is determined by his/her bod’s physiological state at stimulus onset.
arousal= performance

Question 25

Scoreable data

Answer 25

A physiological tracing is considered suitable for comparative purposes when there is no excessive noise on the signal of interest at the time the stimulus is applied or when an exception applies.

Question 26

Tracing size

Answer 26

PN= 2-4 chart divisions
EDA= 4-8 chart divisions
CD=2-4 chart divisions

Question 27

3 positional numerical scale

Answer 27

-1 0 +1
If RQ is more significant = -1
If CQ is more significant = +1
Equal or no response= 0

Question 28

7 position numerical scale

Answer 28

-3 -2-1 0 +1 +2 +3
