In the complex world of forensic science and security, the Psychophysiological Detection of Deception (PDD), commonly known as polygraph testing, plays a pivotal role. Ensuring the credibility and reliability of these examinations is crucial, a task undertaken with great responsibility by the American Society for Testing and Materials (ASTM) through its comprehensive standard guide, ASTM E2062-11(2017).
Introduction to ASTM E2062-11(2017)
The ASTM E2062-11(2017) standard guide outlines the procedural foundation and methodological framework for conducting PDD examinations. It aims to promote consistency, reliability, and professionalism within the field of polygraphy. By establishing a set of best practices, the guide assists examiners in maintaining a high level of ethical standards and scientific integrity throughout the examination process.
Key Components of the Standard Guide
- Examiner Qualifications and Responsibilities: The guide specifies the qualifications necessary for a professional to conduct PDD examinations. It underscores the importance of comprehensive training, adherence to ethical standards, and ongoing education to keep abreast of advancements in polygraphy.
- Pre-test Phase: This section details the procedures for conducting pre-test interviews, including the establishment of rapport with the examinee, explanation of the test process, and formulation of test questions. It emphasizes the necessity of obtaining informed consent and ensuring that the examinee fully understands the examination’s scope and purpose.
- Testing Environment: ASTM E2062-11(2017) delineates the requirements for the physical setting of the examination. The environment must be free from distractions and conducive to concentration, ensuring that external factors do not adversely affect the examinee’s responses. The standard guide specifies that the examination area should be adequately isolated to prevent interruptions and preserve the integrity of the test data.
- Question Formulation: The guide provides a framework for constructing and sequencing questions during the PDD examination. It emphasizes the need for clarity, relevance, and neutrality in question formulation to elicit reliable physiological responses from the examinee.
- Data Analysis: This component of the standard guide addresses the methods for analyzing the physiological data collected during the examination. It stresses the importance of objective and standardized analysis techniques to accurately interpret the results.
- Post-test Procedures: The guide outlines the procedures for conducting post-test interviews, including the presentation of results and the opportunity for the examinee to clarify any deceptive or inconclusive responses.
Impact and Implementation
The ASTM E2062-11(2017) standard guide has significantly impacted the field of polygraphy by providing a comprehensive and structured approach to PDD examinations. Its adoption has led to improvements in the accuracy and reliability of polygraph testing, enhancing its credibility as a tool for truth verification in various contexts, including law enforcement, national security, and employment screening.
The guide’s emphasis on ethical practices and the protection of examinee rights has also contributed to the professionalization of polygraphy, fostering trust in the examination process and its outcomes.
Conclusion
The ASTM E2062-11(2017) Standard Guide for Psychophysiological Detection of Deception (PDD) Examination Standards of Practice represents a cornerstone in the field of polygraphy. By standardizing the procedures and practices of PDD examinations, it ensures that polygraph testing remains a reliable, ethical, and scientifically grounded tool in the pursuit of truth. As polygraph technology and methodologies continue to evolve, the principles outlined in this standard guide will undoubtedly continue to serve as a foundational reference for professionals in the field.
