POLYGRAPHICAL Meaning and Definition

  1. Polygraphical is an adjective that pertains to the field or practice of polygraphy. Polygraphy is a scientific method used to detect and measure physiological responses in order to ascertain the truthfulness or deception of an individual. Therefore, polygraphical refers to anything related to the application or use of a polygraph device or the process of polygraph testing itself.

    In the context of law enforcement or forensic investigation, a polygraphical examination involves the monitoring and recording of various physiological parameters, such as blood pressure, breathing rate, heart rate, and galvanic skin response. These measurements are obtained through the attachment of sensors to the examinee's body while they are asked a series of questions. The polygraph machine then analyzes the obtained data to determine whether there are significant changes in the individual's physiological responses, which could indicate deception.

    Polygraphical techniques are often used in criminal investigations, employment screenings, and other scenarios where determining the truthfulness of a person's statements is paramount. However, it is important to note that although polygraphy is widely used, its accuracy and reliability have been a subject of debate among experts. While some believe that polygraphical testing can provide valuable insights into a person's veracity, others argue that it is not foolproof and can be influenced by various factors, such as anxiety or the skill of the examiner.
