Forensic Psychology & Behavioral Science

Forensic psychology and behavioral science focus on understanding criminal behavior, evaluating suspects, and assisting in legal proceedings. It plays a vital role in criminal profiling, witness testimony, and mental health assessments in the justice system.

1. Criminal Profiling
  • Analyzes behavioral patterns to identify likely suspects.
  • Used in cases of serial crimes (e.g., homicides, sexual assaults).
  • Profilers study crime scenes, victimology, and offender psychology to predict suspect characteristics.
2. Lie Detection Techniques (Polygraph)
  • Measures physiological responses such as heart rate, blood pressure, and respiration.
  • Determines whether a suspect is lying based on stress-induced reactions.
  • Polygraphs are controversial but used in some investigations.
3. Eyewitness Testimony & Memory Analysis
  • Evaluates the reliability of witness statements.
  • Studies show that memory can be distorted by stress, leading questions, and time delays.
  • Techniques like the Cognitive Interview Method improve recall accuracy.
Forensic psychology helps law enforcement understand criminal motives and assess suspect credibility.
