The student delegation for the National Immersion Program had successfully arrived in Delhi:
The day began with an insightful session by Dr. Ranjeeth, who introduced us to the field of forensic psychology and sciences.
He provided valuable insights into various domains within forensics and guided us through the forensic processing framework, which encompasses four key principles: comparison, analysis, probability, and circumstantial facts.
The morning session also covered identification processes and introduced us to deception detection technologies such as the polygraph, narco-analysis, Brain Electrical Oscillation Signature (BEOS), Layered Voice Analysis (LVA), and the Suspect Detection System (SDS). Additionally, we explored different types of forensic evidence.
The afternoon session was led by Afreen Ma’am, where we gained a deeper understanding of the psychological aspects of forensic investigations.
The evening session focused on interrogation and confessions, supplemented by hands-on experience with personality assessments such as the Trail Making Test. We also received a brief introduction to projective techniques and interpreted the Rorschach Inkblot Test. Furthermore, we discussed the importance of cultural adaptation in psychological assessments.
Here is a quick short video on students learning reflection.
An overview of the session objectives was provided. Brief introductions of the three expert from Brilliant forensic investigation, each specializing in lie deception and polygraph technology.
Discussed the components of the polygraph machine, including Galvanic Skin Response (GSR), Respiratory Monitors and Cardiovascular Monitors.
Principles of polygraph technology (physiological measurements: respiration, blood pressure, and skin conductivity) were taught.
Students observed and participated in a live polygraph test demonstration. Discussion of test results, analysis techniques, and real-time challenges faced by examiners.
Students had the opportunity to demonstrate the test on a subject as well as to experience it as a subject.
This session led to the experience of real crime scene with the team divided into various roles like victim , crime executor, witness and investigators.
A brief knowledge about documentation and preservation of evidences especially through photography (Closeup , mid-range, overview) and videography was instructed.
Discussion on the crime sequence was briefed clearly and misinterpretations were resolved.
The session ended with the demonstration on fingerprint development technique and nuances of handling the tools like brushes and powders (white powder, black powder, fluorescent powder) based on the surface and object colours were shown and students were allowed to conduct.
The session comprehensively explored the technical components of polygraph machines, including Galvanic Skin Response (GSR), respiratory, and cardiovascular monitoring systems. Students gained in-depth insights into measuring involuntary physiological responses during interrogations, learning how subtle changes in breathing patterns, blood pressure, and skin conductivity can potentially reveal deceptive behaviors.
The training was highly interactive, featuring live polygraph test demonstrations where students not only observed professional examinations but also actively participated as both test administrators and subjects.
This hands-on approach allowed students to understand the real-world challenges and nuanced techniques involved in lie detection.
