WHAT IS POLYGRAPH?
The term "polygraph" literally means "many writings." The name refers to the manner in
which selected physiological activities are simultaneously recorded. Polygraph examiners
may use conventional instruments, sometimes referred to as analog instruments, or
computerized polygraph instruments.
It is important to understand what a polygraph examination entails. A polygraph instrument
will collect physiological data from at least three systems in the human body. Convoluted
rubber tubes that are placed over the examinee's chest and abdominal area will record
respiratory activity. Two small metal plates, attached to the fingers, will record sweat gland
activity, and a blood pressure cuff, or similar device will record cardiovascular activity.
A typical polygraph examination will include a period referred to as a pre-test, a chart
collection phase and a test data analysis phase. In the pre-test, the polygraph examiner will
complete required paperwork and talk with the examinee about the test. During this period,
the examiner will discuss the questions to be asked and familiarize the examinee with the
testing procedure. During the chart collection phase, the examiner will administer and collect
a number of polygraph charts. Following this, the examiner will analyze the charts and
render an opinion as to the truthfulness of the person taking the test. The examiner, when
appropriate, will offer the examinee an opportunity to explain physiological responses in
relation to one or more questions asked during the test. It is important to note that a
polygraph does not include the analysis of physiology associated with the voice. Instruments
that claim to record voice stress are not polygraphs and have not been shown to have
scientific support.
Polygraph testing is mainly done for private business sector purposes in South Africa.
