On deception - Lab Report Example However, the administering of even these scientifically-based tests has come under increasing fire. For example, polygraph results were barred from the trial of a U.S. trial of a federal judge as recently as December of 2008 (Assoicated Press, 2008). If such a scientifically-based device has come under such scrutiny and has been routinely barred from legal proceedings, it begs the question of whether an unaided human can detect deception merely by observing the subject. In their 1996 study, Vrij and Semin examined this question by recruiting not only college students, but also subjects from a variety of fields thought to be trained and experienced in lie detection (police patrol officers, prison guards, customs officials, etc.) as well as those constantly exposed to an environment based on lies and deception (prisoners). It was their hypothesis that law enforcement officials would be better at lie detection than "normal people" such as college students and that the criminals would have superior abilities to those of law enforcement. All of the subjects reported that they considered themselves highly experienced at detecting deception (Vrij & Semin, 1996). Vrij and Semin administered their study through a series of questionnaires administered at the subjects' places or work or incarceration. These questionnaires contained questions ranging over 16 nonverbal cues commonly associated with deception and concluded with the subjects rating themselves on their ability to detect deception in others on a 7-point scale. The results were compiled by group (college student, law enforcement, or criminal) and then analysed for accuracy. As predicted, the criminals exhibited the greatest level of accuracy in correctly identifying nonverbal cues of deception. It was also found that there was not a significant difference between the accuracy rates of law enforcement and college students, indicating that those considering themselves professional lie detectors fell victim to the same misconceptions on nonverbal cues as a lay person (Vrij & Semin, 1996). While Vrij and Semin's study does provide useful data that professional lie detectors have no superior knowledge of deceptive nonverbal cues than the rest of us, it does lack in that none of the subjects were actually tested in their ability to detect deception. This study will address that lack by actually testing whether or not subjects can detect deception through nonverbal cues, particularly by focusing on voice pitch. It is predicted that such attention to nonverbal cues will detect deception at a higher rate than chance and that those observers relying on voice pitch as a deceptive cue will be more accurate than observers relying on other nonverbal cues. Methods A pool of 761 subjects was recruited consisting of 454 females and 307 males who were informed that they would be participating in an undergraduate psychology tutorial study. These subjects ranged in age from 17 to 56 years with a mean age of 19.77 years and a standard deviation of 2.58 years. For this study, each subject was instructed to tell a story to another subject. This narrative could either be true or false and the observer

Assignment 13 Example | Topics and Well Written Essays - 500 words

13 - Assignment Example are different in employment of labor where in some organizations, workers have the freedom to choose what they want to do while in others, duties are assigned to employees. However, many inequalities that arise from the nature of the employment, as identified by, Adam Smith need to be addressed to create harmony in the work place. These principal counter balances in some employment while in others, it is a gain. The first principal, the wages of labour vary with the hardship, the cleanliness, the honorableness of the employment. Those who carry out heavy duties earn more that those who undertake light duties. Additionally, dirtier work tends to fetch more wages than the clean ones and exposure to unsafe or dangerous environment (Smith and Dickey, 1993). The employees in dishonorable employment may take home more wages than those in the honorable employment because it takes patience and courage to carry out the duties; however, this is not always the case in all employment. This also applies in the profits of stock the bigger the stock the more the profit it earns. Secondly, the wages of labour vary with the easiness and cheapness, or the difficulty and expense of learning the business. If an employment requires a skilled person who have taken enough time to learn about it and used expensive resources, the level of wages must be high. This is because time consumed in training is great and not just anyone who can perform the duties especially the specialized ones be it technical or technological. Skilled labour fetches more wages and as one upgrade the position is left vacant for another to join and learn as the latter continues with his/her training under the master just like it is in Europe (Smith and Dickey). Easiness and cheapness hardly affect the stock of profit because for any business to do well, a lot of effort must be employed. Thirdly, the wages of labour in different occupations vary with the constancy or inconstancy of employment. Employment varies
