Phallometry In Chicago, IL
What is Phallometric Testing, Plethysmograph, or PPG?
Phallometric testing using the penile plethysmograph (PPG) is designed to measure sexual response to visual and auditory non-pornographic stimuli. Phallometric testing provides objective information about male sexual interests. The findings are useful not only to the attorneys, courts, probation, parole, but more so to the patient himself. Phallometric testing process includes four phases: interview, testing, data interpretation, and feedback. Phallometric test results are NOT used to make inferences about guilt or innocence.
We use PPG Monarch 21 system. The system is portable and the technician or clinician can travel to the site in order to perform the testing and evaluation.
Phallometric testing is available for males age 18 and older, for individuals with developmental or intellectual disability (IQ less than 70), for individuals with severe attention deficit problems, and for juveniles who are at least age 15 or older.
Along with PPG results, Galvanic Skin Response (GSR) and Respiration (RESP) are sampled to detect attempts at deception. The particular pattern of responses across all measures can be used to determine the confidence one might place on an individual’s self-reported sexual interests and behavior.
Phallometric testing results are considered along with other information relating to the individual, e.g., individual’s past and present behaviors, attitudes, and other psychological data to accurately assess one’s patterns of sexual arousal.
PPG is an FDA approved device and is admissible in courts as evidence.
