The saying, “The mouth can lie, but the body can’t” is largely true. During an interview, increased cognitive activity often “leaks” out into a person’s body language, behavioral activity, and other physical manifestations that, to the trained eye, are indicators of guilt and/or deception. In this webinar, we explore some of the common behavioral leakages that manifest during forensic interviews and examine a number of case studies of actual interviews.

Some other presenters spend more time talking about their own contributions to the field or discussing their literature review; as a result, the educational part of the presentation takes away from the application portion.

  • “I’m a CASA now that I have retired. I have had some training using Mark McClish?? material as an educator, and school administrator to conduct evidence-based interviews with students and staff. This was fascinating. I now work with teen boys mostly as a CASA. I want to sharpen my ability to know when they are lying. This was a great review of some material and an intro to new material. If I wasn’t retired I’d take all your courses to get certified. So helpful.” — Anne

  • “I loved the format of giving an overview of the main concepts, and then using the case studies to highlight how the concepts can be used in practice. Ray is an excellent speaker and I liked how he paused the case study videos to give insight. I’d love to see more webinars from Ray in the future!” — Sarah
  • “This was one of the best webinars! So much information. Just fascinating! Loved it and really enjoy listening to Ray Nash! He is so informative. I have supervised sex offenders on Probation for most of my 30 year career and I find behavior observation so interesting.” — Devra
