You will learn about the stress response during lying and the roles of fear, anxiety, and guilt. Additionally, the module covers the physiological responses to stress, highlighting the body’s reaction when individuals are deceptive.

MODULE 4 – SCIENTIFIC FOUNDATION OF POLYGRAPH TESTING 

This module covers the scientific principles and methodologies behind polygraph testing. You will gain insights into the theories behind polygraph mechanisms, polygraph instruments and their components, and the structured phases of polygraph exams—pre-test, in-test, and post-test. You will also learn about the factors influencing polygraph outcomes, techniques for interpreting data, and the various types of polygraph tests used in forensic investigations.

MODULE 5 – VALIDITY, RELIABILITY, AND ACCURACY OF POLYGRAPH TESTS 

This module examines the critical aspects of polygraph testing, focusing on its validity, reliability, and accuracy. You will explore theories of validity as applied to polygraph testing, techniques for measuring polygraph test accuracy, and the importance of consistency and repeatability in results. Additionally, the module highlights the legal considerations surrounding the admissibility of polygraph tests in courtrooms.

MODULE 6 – RESEARCH METHODS IN POLYGRAPH TESTING 

In this module, you will learn about the methodologies used to study polygraph testing, offering insights into both laboratory and field studies for validating polygraph techniques. You will gain insights about effective data collection methods in polygraph research while addressing critical issues such as bias, conflicts of interest, and ethical challenges involved in conducting and interpreting research.

MODULE 7 – POLYGRAPH TEST ACCURACY AND ITS MEASUREMENT 

This module focuses on evaluating the accuracy of polygraph tests by analyzing criterion validity and the effects of countermeasures on test accuracy and outcomes. You will explore the implications of false positives and negatives, along with a structured approach to measuring accuracy across varied contexts, ensuring reliability and precision in polygraph assessments.

MODULE 8 – APPLICATIONS OF POLYGRAPH TESTING IN LAW ENFORCEMENT 

This module explores the diverse applications of polygraph testing within the legal and law enforcement domains, including its use in criminal investigations and trials, pre-employment and security screenings, national security, and counterterrorism. Additionally, you will learn to examine special populations and conditions while addressing the ethical considerations unique to polygraph testing in legal contexts.

MODULE 9 – ETHICAL AND LEGAL CONSIDERATIONS IN POLYGRAPH TESTING 

This module focuses on the ethical and legal considerations in polygraph testing. You will learn about legal standards for polygraph test admissibility, ethical challenges faced during polygraph examinations, and the importance of informed consent and confidentiality. Additionally, the module covers the legal rights of individuals undergoing polygraph tests, ensuring a deep understanding of the framework governing this practice.

MODULE 10 – COUNTERMEASURES IN POLYGRAPH TESTING 

This module explores strategies and techniques related to countermeasures in polygraph testing. Topics include detecting countermeasure attempts, assessing their effectiveness, and training polygraph examiners to identify deceptive techniques. You will also gain insights into psychological profiling and methods for recognizing behaviors associated with deception, enhancing the reliability and accuracy of polygraph results.

MODULE 11 – ALTERNATIVES TO POLYGRAPH TESTING 

This module highlights the use of advanced technologies as alternatives to polygraph testing, which includes the use of functional magnetic resonance imaging (FMRI) and brainwave analysis, voice stress analysis for deception detection, thermal imaging techniques, and the role of eye tracking in identifying deceitful behavior. These methods aim to enhance precision and address limitations of traditional polygraph tests.

MODULE 12 – OTHER SCIENTIFIC AIDS FOR INVESTIGATION 

This module covers advanced scientific techniques that aid investigative processes, enhancing the accuracy and efficiency of traditional methods. It covers brain electrical oscillations signature (BEOS) profiling, layered voice analysis suspect detection system, along with narcoanalysis, a controversial method involving the use of truth-inducing drugs during investigative interviews. Together, these techniques provide investigators with powerful tools to discover crucial evidence and insights.
