Overview

How do these tests compare in accuracy to the existing PPG standard tests?

Summary

There are two main ways to test for sexual interest in an individual.  They are the penile plethysmograph (PPG), and the Visual Reaction Time (VRT) test called the ABEL, after it’s creator.  These instruments objectively test an individual’s sexual interest to various ages and races of cis gender males and females.  While other measures exist, like the LOOK, they do not have as much of a research base behind them.
