Hi Kipp,Our polygraph suite allows you to present digital visual and audio stimuli to the examinee during a polygraph exam. It works by using a second computer monitor that is connected to your desktop or laptop computer. The digital images that you want to display are easily set up in our question editor. You could type out the test questions that you want displayed to the examinee and capture the text as a digital bit map or image that would be displayed to the examinee via the secondary display they are watching. The examinee would see your question and respond accordingly. The time that the image is displayed can be controlled with your spacebar or you can enter a pre-defined period. Nice little solution if you're using a Limestone. If you need more information or details about how easy this is to accomplish give us a call.

Greetings from Australia! I have been asked to test two deaf people in the past which has presented some interesting challenges. What I have done, which has worked quite well, is have a person fluent in sign language sit direcly in front of the examinee. I then ask the questions but only hit the space bar when I see the the sign interpreter commence. I hit the space bar once again when the sign interpreter stops signing. The deaf person is instructed to blink their eyes (once for yes twice for no or similar). This has worked well on both occasions and the blinking prevents movement during the recording process. Alternatively a silent answer test can be used whereby the examinee is not required to respond. I like the blinking personally because the examinee is still commited to signalling his/her answer.Hope this has been of assistance. Good luck with it. ------------------

Kipp. The answers that have been posted should work. A simple solution I used two weeks ago was to have the deaf person read my lips. I angled the polygraph chair so he could see my lips but not the monnitor. The pre test and stim test went well as did the full exam. Of course it depends on the lip reading skill of the person being tested, The other exam I did was in Spain and I used someone who could sign and was trusted,

Kipp,The answers I have read here are all good. Having the video capabilities to show them the question during in-test would be ideal, however not everyone has the equipment. If you do not have the equipment that Jamie described, I too would recommend using an interpreter. I would ensure the interpreter is qualified with sign language. Would hate to have examinee come back later and make accusations that they did not understand the interpreter. I personally would not have the examinee facing me and reading my lips. Again, they could come back and say they did not understand and I don't want them seeing me during in-test. Although I am very disiplined regarding my body language I don't want the examinee watching me during in-test hoping to see some type of "reaction" from me. I would use the silent answer test, proven to be very effective. I am sure many more people will give you other great ideas. Good luck. IP: Logged |

Kipp,This, like any exam w/an interpreter is a challenge. Polygraph is robust and will work with any of the above suggestions (and often in spite of us), but I agree with Esther in recommending the interpreter route, for the very reasons she suggested. I've seen several done with a 'signer' trained to support polygraph exams. It will work just fine. IP: Logged |

Kipp,
Here is another 2 cents worth....I would find out what the subject's strongest method of communication is(sign, written word or lip reading) and go with that. How does this subject usually communicate in their day to day world. Since the most critical part of your test is going to be your interview, you are going to have to be able to communicate through a lot more than just the exam itself. I don't know if you video tape or not. Even if you don't, this may be a good exception. Ted
