fMRI, THE NEW ASPECTS OF DECEPTION DETECTION 1. INTRODUCTION If deception becomes human behaviour, lie detection will play key role of proving their deceit. For a century, researchers studied significantly about deception as the human behaviour in scientific, philosophical and legal aspects (Ford, 2006) and attempted to create the new instruments to detect deception. Many techniques were developed to detect lies and determine the truth (Kleinmuntz and Szucko, 1984 cited in National Research Council, 2003). In early of the 20th century, lie detection was invented by using physiological responses as indicators of deception, known as the polygraph (National Research Council, 2003). Polygraph has been used in many objectives, for example, employee screening, criminal investigating. Almost a hundred years, polygraph paves the way in criminal justice systems effectively. However, there are a number of disadvantages considering an accuracy of the polygraph test in order to detect deception that has limitation. Deceit detection should be more reliable by evaluating the function of the brain individually correlated to lying (Kozel et al, 2005). Functional magnetic resonance imaging (fMRI), the medical instrument, was altered to complete the missing pieces of the scientific puzzle. If fMRI can meet the standards of legal reliability, it will be the new aspect of lie detection (Langleben and Moriarty, 2013). The purpose of this report is to present the development and weaknesses of
