This week we will talk about recent news related to Psychology in the past couple of months...
This news is not only important for a reader of Psychology but also can help you gauge into various new theories coming up! This may also be really important for General knowledge and competitive exams. Who doesn't like to stay updated about RECENT NEWS?
Very few people know this but a new method to detect liars has come up! Polygraph tests are a thing of the past as they measure things like respiration, heart rate, and skin conductivity .
But as the APA says "There is no evidence that any pattern of physiological reactions is unique to deception.” A liar could have an even heart rate, and a truth-teller could see theirs spike from nerves. Another flaw of a polygraph test is that if the victim indulges pain on themselves the tests results could be fabricated!
Research published in the Journal of Applied Research and Memory and Cognition has identified new cognitive-based lie-detection methods.
"Our technique is part of a new generation of cognitive-based lie-detection methods that are being increasingly researched and developed," Porter who developed this technique and is the mastermind behind AIM explains that "These approaches postulate that the mental and strategic processes adopted by truth-tellers during interviews differ significantly from those of liars. By using specific techniques, these differences can be amplified and detected."
One such technique is the Asymmetric Information Management (AIM) technique. It is designed to provide suspects with a clear means to demonstrate their innocence or guilt by providing detailed information. Minor details are the lifeblood of forensic investigations and can provide investigators with facts to check and witnesses to question.
Thus, more detailed statements typically contain more clues to a deception than short statements. AIM focuses on an investigator informing suspects that divulging longer, more comprehensive details about a situation can help the investigation better detect if they’re being truthful or not.
Hence, through this study it was concluded that, those who are innocent are more likely to provide detailed information to prove their innocence, while dishonest suspects may still conceal and withhold information. - Soumya Gulati
