The Linguistic Statement Analysis Technique, LSAT, is advanced investigative technology and law enforcement training that is highly effective in detecting deception and lies in spoken and written statements from victims, suspects and witnesses in all crimes and legal depositions. Investigators who receive statement analysis training have found it to be an effective and efficient investigative technique used in homicide investigations, arson investigation, robbery investigation, theft investigation, sexual assault investigation, espionage investigation, vandalism investigation, insurance fraud investigation, and all other crimes. 

This course is highly recommended for Criminal Investigators, Arson Investigators, Private Investigators, Criminal Forensic Specialists, Reporters, Attorneys, and Human Resource Personnel.

Applying LSAT to a written statement is like subjecting someone to a polygraph examination. LSAT detects deception by training the investigator to identify linguistic signals that indicate whether a suspect or victim is deceptive and lying, or whether they are being truthful.  The investigator performs a statement analysis, identifies in which parts of the story they are deceptive, and then strategizes an interview or interrogation to elicit a confession.

Every human brain uses the same subconscious strategies to deceive, by using different words and phrases, statement structure and content in their statements than truthful ones. Years of research by experts in the fields of language, psychology and deception detection have led to the identification of these trends in language that are referred to as linguistic signals. Using LSAT you will identify these linguistic signals that differentiate deceptive statements from truthful ones. It is equally effective when used on suspect, witness, and victim statements alike.

LSAT is dedicated to having its students effectively learn the LSAT technique and develop a significant level of competence.  We are actual working investigators who have a true desire to have others share in our success.

At LSAT, we do not simply lecture, tell war stories, and show a fancy slide show and expect our students to learn.  We incorporate proven adult learning strategies by using properly trained instructors who possess valid and legitimate teaching credentials.

Training is not really training unless it incorporates all processes by which people effectively learn: hearing, seeing, doing, and correcting/reinforcing.  LSAT training effectively incorporates lecture, demonstration, the clarification of questions, assisted practice, and demonstrating proficiency.  But there is more to our teaching strategy.

LSAT training includes FREE follow up expert consultation, advice and reinforcement of the skills and knowledge it teaches.  LSAT does not leave our students fending for themselves once they have completed our training.  We are always a phone call or email away, eager to provide follow-up support.
