...Polygraph (Lie Detector) Tests Name of Student Name of University Polygraph (Lie Detector) Tests Employee Polygraph Protection Act Employee Polygraph Protection Act outlawed the use of polygraph or lie detector tests in connection with employment. The Act covers private employers in security businesses and those who authorized to distribute controlled substances (Carper, 2011). However, the Act does not apply on state, federal, and local employers of Government and those work in handling sensitive information related to national defense. Under the law, it is not legal for any private company to suggest or require any employee to submit polygraph tests. The Act does not allow accepting or inquiring the results of polygraph tests conducted on employees. It prohibits private companies from dismissal, discrimination, and even threatening the employees who rejects to take polygraph tests. Conditions for Using Polygraph Tests The federal law allows using the polygraph tests in connection with employment in drugs handling and investigating suspected crime or specific theft. However, employers must sent a written notice to the employees before 48 hours of conducting polygraph tests as part of an employment-related crime or an investigation (Grubin, 2005). The employers must have reasonable and provable suspicion of involving employees in theft or any other investigation. Limitations on Polygraph Tests The Employers must act...

TheMOST IMPORTANT usage of a residential alarm system is when you are the most vulnerable, which is when you are asleep. No physical harm can occur to you if you are away from your residence while it is being burglarized.</li> <li> Upon returning home and disarming your security system, even from a very brief absence while you were at the corner convenience store, the alarm keypad will immediately indicate to you that: "While you were gone nothing happened" or "BE CAREFUL - - Here's what occurred in your absence". The alarm keypad's warning message will prevent homeowners from walking into the home and confronting burglars who may still be inside the residence.</li> </ol> My reason Number 2 is especially important for homeowners who don't have interactive notifications from their alarm panels being sent to their cell phones advising them that an alarm has occurred at their home. Additionally, some homeowners have "local alarm systems" that are not subscribed to monitoring services while others have monitoring by a telephone line that the burglars have cut before entering the home. I don't like the over-usage of the word "protection"...

...about what you were doing earlier to your friend, when really you were at the mall buying her a birthday present for her birthday that weekend. A negative example of lying would be a girlfriend cheating on her boyfriend, and lying about what she was doing instead. Then you have situations where you lie and agree with someone just to keep a conversation going. You also have compulsive liars who feel the need to lie about everything they do and talk about. Sometimes these people get so convinced on what they are lying about themselves, that they don’t even know how much they do it or when they do it. Both men and women lie in approximately a fifth of their social exchanges lasting 10 or more minutes; over the course of a week they deceive about 30 percent of those with whom they interact one-on-one. (Phycology Today, 1997.) Now if you’re in a criminal situation and they only have your feedback to go off of, they need to test whether or not you’re lying. In order to do this, they need to use a polygraph or brain scanner. These lie detecting technologies aren’t 100% effective. My question is if they will ever be improved or 100% accurate. While looking up how we benefit ourselves with the lie detection technologies we use today, I came across articles with a similar outlook and proposal. In the research, I was able to see all the experiments done from college students around the world for up to 40 years that led to what devices we use today. Right after reviewing this I was able to encounter...

...ABSTRACT Detecting deception By RACHEL ADELSON July/August 2004, Vol 35, No. 7 Print version: page 70 Research has shown that even agents from the FBI, CIA and Drug Enforcement Agency don't do much better than chance in telling liars from truth-tellers. Spotting the sneaks can be tough. Polygraph tests- so-called "lie detectors"--are typically based on detecting autonomic reactions and are considered unreliable. They warn readers that detecting deception is an inexact science, but note an association between lying and increased pupil size, an indicator of tension and concentration. Second, they find that people listening to liars think they seem more nervous than truth-tellers, perhaps because their voices are pitched higher. And liars are more likely than truth-tellers to press their lips together. On the other hand, they note, liars don't appear to be more fidgety, nor do they blink more or have less-relaxed posture. According to DePaulo and Morris, only when liars are more highly motivated--when the stakes are higher--do they seem unusually still and make notably less eye contact with listeners. the Facial Action Coding System (FACS), which, when combined with voice and speech measures, reaches detection accuracy rates of up to 90 percent, Ekman claims. Ekman, through close study, learned that "micro-expressions" lasting less than one-fifth of a second may leak emotions someone wants to conceal, such as anger or guilt. DePaulo and Morris say that liars take longer to start...

...it is a natural part of human behavior, which most likely started at age three or four. Many studies even confirm that very few people in the world can go through an entire day without lying even once. The negotiation process is like poker because while players are expected to play fair, there aren’t any guidelines to whether or not deception may be used to win a game by making others overestimate the value of one’s hand. As such, negotiators are employ any tactics necessary to get ahead, including lying. This is not done deliberately to hurt anyone, rather to reach their goal faster. While it is morally wrong to lie, the legality of lying is so complex and ambiguous that it is very to prove because as stated by Richard Shell in a 1991 article in Sloane Management Review called “When is it legal to lie in negotiations,” he explains the criteria needed to prove a lie under American law is so vague that the preset assumption is that no fraud is committed because every party has the choice of walking away from outrageous demands. However, he states there are five elements to fraud law that must be met: knowing, misinterpretation, material, fact and lastly, reliance and causation of fraud in order for it to stand in a court of law. Shell goes on to concede that most misleading statements are made to simply gain an edge in negotiations, which is perfectly normal because that the two parties don’t have to have a fiduciary relationship, thus it is alright for parties to employ tactics...

...one could see through to the truth. “Human society would be orderly, boring and as alien as an anthill,” he notes. If only there was a machine to read others’ minds… There is such a machine, but to some extent, can only measure anxiety, taken to mean as a lie. This machine, the polygraph, also known as the “lie detector”, only can hint whether a subject is lying. Critics say that the polygraph is flawed because of false positives (an honest answer is mistaken for a lie) and false negatives (a lie is overlooked as a truth). Furthermore, the polygraph is not permitted to use as evidence in the legal system; the National Research Council even called the device “blunt”. There must be a better way to achieve successful end results in looking at others’ thought processes. Ross names famous philosophers and scientists investigating the same problem. Greek philosopher Diogenes went about his life carrying a lamp to look for an honest man in what he thought was a corrupt society. Ross argues that instead of looking for clues of deception on the outside of one’s body (like sweating or breathing irregularly, as found in the polygraph), it is better to look inside one’s brain. There you can not only tell a truth from a lie, but look at how one solves a simple math problem step by step. A scientist who investigates this further is J. Peter Rosenfeld who observed an interesting feature in the EEG (electroencephalograph; chart of brain’s electrical signals) in which lying also elicited...

...down on it after asking the question. I am looking for any signs of a differing pressure or restraint they have in their arm after a question to hint that they have lied. The mental test is a test where I look for visual hints in the person’s actions after I ask a question, anything unusual could hint that they have lied. I have conducted this experiment by having typed a 15-question survey that I will hand out to 10 people, five I will conduct the physical test on and the other half the mental test. Once they have filled out the survey I will then have them pick at random five cards labeled 1-15 in which they will lie on. I will see neither the cards nor their survey. Then I conduct the tests. My hypothesis is that the mental test will lead to more correct detected lies. Works Cited "Pinocchio's Arm: A Lie Detector Test." Pinocchio's Arm: A Lie Detector Test. N.p., n.d. Web. 04 Dec. 2014.

...law enforcement procedure, and the role of nonverbal communication play with regard to detecting deception. The Ethics of Deception Ethical and moral behaviors are characteristics that individuals have but not all individuals have the same degree of moral ground. Everyone has the right to free choice and free-thinking, which are the foundation of the pursuit of happiness, life, and liberty. Within the context of free choice, humans have the choice of telling the truth or lying. Truth is usually only given freely when the foreseen benefit exists; otherwise most individuals will resort to a lie. By nature, humans do not want to experience pain, harm, or anything that may restrict individual freedoms. For individuals who violate laws, social norms, or otherwise commit an act, which will resort in a consequence, lying is a rational choice to prevent said consequences. People who lie often have an increasing sense about his or her surroundings, non-verbal communication presence, and internal thought process. These actions by individuals make it increasingly harder for law enforcement personnel to extract the truth from a suspect. The use of...

...This question can fill volumes so I am going to tackle the two most prevalent aspects to what will happen if you lie. Health Ramifications Most of us can remember when we last told a lie, or when the lie required you to recall details of what it was about. You may recollect feeling stressed, anxious and actually having an adverse physical reaction because you had to guess at the specifics of the lie? What’s even more daunting is what you thought was believed to have been forgotten, may now be overwhelming your thoughts despite your efforts to forget about “it”. Psychology researchers at the University of Notre Dame conducted a 10-week study on a group of 110 individuals, half of which were asked not to lie, and the other half told to keep track of how many times they actually lied. [1] The researchers followed each participant’s mental and physical health with survey’s...

...interviewee, which could lead to the responsible individual being charged with a crime. Also, a best practice forensic interview can enhance the ability to detect cues associated with deception. Cues to deception and the forensic interview will be addressed in the present study using an investigative mock crime interview paradigm. Firstly, the most predominant theoretical frameworks specific to linguistic cues to deception and the relevant literature will be presented. Then, the arousal signals of deception will be briefly reviewed. Finally, the importance of a best practice interview in forensic investigations will be discussed to find how it can potentially benefit deception detection. Literature Review People are notoriously poor lie detectors, even after undergoing training (Vrij, 2008). For example, a recent review found that people were able to distinguish between truth and lies only 54% of the time (Bond & DePaulo, 2006). Most research has paid exaggerated focus to non-verbal cues, including facial expression, vocal pitch and gesture, which either subjectively rely on human judgement or fail to achieve acceptable accuracy levels on a consistent level (Vrij, 2008). A recent meta-analysis suggested that only training in the recognition of verbal cues can improve deception detection (Hauch et al., 2016). However, technological progress means that linguistic cues can now be assessed automatically by utilising computer-based software such as Linguistic Inquiry and Word Count...

Stephen Porter* and Leanne ten Brinke University of British Columbia Okanagan, Kelowna, British Columbia, Canada In this paper, we provide our view of the current understanding of high-stakes lies often occurring in forensic contexts. We underscore the importance of avoiding widespread pitfalls of deception detection and challenging prevailing assumptions concerning strategies for catching liars. The promise and limitations of each of non-verbal/body language, facial, verbal/linguistic, and physiological channels in detecting deception are discussed. In observing the absence of a single cue or behavioural channel that consistently reveals deception, a holistic approach with concurrent attention to multiple channels of a target’s behaviour (ideally videotaped for review) and changes from baseline behaviour is recommended whenever possible. Among the best-validated cues to be considered together include: illustrators, blink and pause rate, speech rate, vague descriptions, repeated details, contextual embedding, reproduction of conversations, and emotional ‘leakage’ in the face.

...conducted on the same problem in the past. In fact, polygraphs, more commonly known as lie detectors, have existed for quite some time. The idea for a polygraph was brought about by Cesare Lombroso in the year 1895. He was an Italian psychiatrist who believed he could use factors such as blood pressure, heart rate, and physical behaviors to determine whether or not the test subject was lying. However, back then his theory was quickly shoved to the side and dismissed along with his other theory of identifying criminals using the shape of their skull. At the beginning of the 1900’s a scientist by the name of William Marston decided to try and refine the design of the polygraph. Around the years of 1917 and 1923, William Marston had made a working lie detector. He stated that he could correctly deduce whether or not the subject was lying, with 95% accuracy (White 2001)....
