Can you name a voluntary and involuntary response of the nervous system during a polygraph test?

Answer 1

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 voluntary response might be biting ones lip, grimacing, laughing

Answer 2

HERE'S YOUR VERY SIMPLE SOLUTION!!!!! It's an open secret in law enforcement circles (as well as employers who use polygraphs) that the vaunted "lie detector tests" DO NOT WORK. They rely simply upon the skill of the operator to make the subject BELIEVE that they work. The operator must be a skillful psychologist who is able to convince the subject that the test is "foolproof" and "can't be beaten". This has been proven in laboratory experiments where subjects have either been told that a new type of polygraph is 100% right, and other subjects have been told the truth, that the polygraph measures certain physiological effects which may or may not be triggered by anxiety,fear, suspicion, or other emotional states, and that the operator has to interpret the results in light of his own observation and judgment based on his training and experience. Relax, you have nothing to fear, Simply think of calming things and be as truthful (or dishonest) as you wish.

Answer 4

Muscles tightening or fidgeting is more or less voluntary, blood pressure and heart rate changes are involuntary.

Answer 5

Breathing could be either.
involuntary-heart rate, sweating, blood pressure
