There has always been a desire to find the right tool/ machine that would help undiscovered the truth about a particular subject/topic. The device would help revolutionize the way crime is detected and the way police conduct their interrogation (Costanzo, M, & Kraussr, pg 54). The devices that was invented was called the polygraph. The polygraph tests main purpose was to discover the unforeseen truth that is behind the human eye. The results that comes from the machine are supposed to be accurate and detect any false statements. There has been three polygraph test that have been created to increase the validity of each test. The three tests are Relevant-Irrelevant tested (RIT), Comparison Question test (CQT), and lastly Guilty Knowledge test (GKT). …show more content…
Each procedure consisted of three questions. The following questions as followed nonarousing questions, arousing questions, and relevant questions. Each question that was asked is based on a predetermined sequence that judges the strength of each question. If the suspect is guilty the response to the arousing question should be stronger, meaning a stronger reaction. Therefore, concluding the suspect to be classified as deceptive (Costanzo, M, & Kraussr, pg 54).
The CQT test was created to counteract the errors that exist within the RIT. The CQT is the most widely used in the polygraphing era. CQT relies heavily on relative arousal. The common questionnaires questions that are used are called the control questions. The questions consist of unfavorable questions that make the suspect feel uncomfortable. The control questions are equivalent to the relevant questions from RIT. The proposition is that innocent suspect will react more strongly to the control questions and guilty suspect will react more strongly to the relevant questions (Costanzo, M, & Kraussr, pg
In “The Interview” by Douglas Starr, He talks about the different techniques they use when interrogating suspects to determine whether the suspect is lying. One technique they use is called the Reid Technique and that is when
The use of eyewitness statements and testimony’s can be a great source of information, but can also lead to wrongful convictions. Due to eyewitness testimony, innocent people are convicted of crimes they have not committed. This is why the wording of a question is important to consider when interviewing witnesses. Due to the fact that eyewitness testimony can be the most concrete evidence in an investigation, witnesses may feel they are helping an officer by giving them as much information as possible, therefore they may tell them information that is not entirely true, just to please them. This is why there are advantages and disadvantages to using open and close ended questioning at different durations of an interview. The way you word a question may impact the memory of a witness, this is because a person cannot completely memorize the exact occurrences of an event.

There are certain standards that the courts use to determine competency. In order to find the accused competent, a court should find out by a preponderance of evidence that the defendant has remarkable ability to consult with his lawyer with a reasonable degree of rational indulgence. The def...
One of the last types of ways investigators are coached to detect deception is in the behavioral attitudes of a person being interviewed such as being unconcerned or over anxious (Kassin, 2005). The success rate of looking for these cues are very successful in telling if an individual is being deceitful and has surpassed any laboratory tests conducted on the subject. The laboratory test however did reveal some interesting facts. The research showed that people who had training and experience did not score better than the control group who received no training. In fact all individuals scored at the chance level with the people who had training scored just above chance or at the chance level. To check if special training in the detection of deception was more accurate a study ...

Many of today’s interrogation models being utilized in police investigations have an impact on false confessions. The model that has been in the public eye recently is the social psychological process model of interrogation known as the “The Reid Technique.” There are two alternatives used by the police today to replace the Reid Technique, one is the PEACE Model and the other is Cognitive Interviewing. These methods are not interrogation techniques like Reid but interview processes.
To show an unbiased and educated examination of the five cases involving questionable interrogations, I will give information on the crime that occurred, the problems with the interrogations and other evidence, who is at fault for problems within the case, how the defendant was cleared (if he was), and the compensation and future changes that were a direct response to these cases provided that they occurred or are in the process of occurring. The five cases that I will examine involve the accused: George Allen, Hunter Johnson, Peter Reilly, Michael Crowe, and Reggie Clemons. Each case is significantly different yet showcases many acts of injustice within the justice system.
Through behavioral assessment, “psychologists can count and record the frequency of particular behaviors” (Wood, Wood, & Boyd, 2014, p. 382). According to the textbook Mastering the World of Psychology, the MBTI’s limitation is that it has an “absence of rigorous, controlled validity studies of the inventory” (Wood et al., 2014, p. 385). Unlike the MBTI, the behavioral assessment takes a deeper, more in-depth look at how people respond to certain situations which I believe is a much more reliable way to understand an individual’s true personality rather than relying on their answers to questions on a

In recent years, however, such programs as CSI that follows detectives at the Las Vegas Police Department Crime Scene Investigations Bureau as they solve puzzles and catch criminals. Perhaps one of the most well known shows with a forensic psychology theme, CSI has a large impact on viewers perceptions of forensic psychology. On one hand, the increased popularity of forensic psychology because of the show is good and more people are taking an interest in forensic psychology as a career. On the other hand, the forensic psychology that viewers see every week on television may not be exactly the same as forensic psychology in reality. Particularly programs such as CSI also overstate the ability of “hard” evidence (also known as forensic evidence), such as fingerprints and DNA, to provide evidence of definite innocence or guilt (Trask, 2007). They often disregard other components of the investigative process, such as police questioning, despite these being equally valid to establishing guilt (Nolan, 2006). This over-reliance on forensic evidence, due to the importance of forensic science being dramatized by television crime dramas, is also known as the CSI
Beginning in the late 1800’s and the early 1900’s forensic psychology originated when a man named James McKeen Cattell conducted a study at Columbia University. During his time learning and coming up with the idea that psychology could be used as a way to solve court cases he did many experiments with his students. In one study he allowed 56 of his students practice eye witness testimonies with a series of questions. He conducted the experiment by asking the students about trees and asked the students to rate their confidence in what they saw and recall what they saw hours later. During this experiment Cattell...
In today’s highly competitive job market it is extremely challenging and important for businesses to fill a vacancy with the right candidate (Cann, 2013). Due to high demand of potential candidates, developing a portfolio of employability skills which include psychometric testing is considered important in every workplace (Mills et al., 2011). Thus, I recently took three practice psychometric tests on verbal, numerical and inductive/logical reasoning. This essay is a reflection of my personal experience of psychometric testing. First, I will talk about what the literature comments on in relation to the strengths and weaknesses of psychometric testing. Then, I will assess whether literature reflects
As far back as 1832, James Marsh was the first to use forensics at trial to give evidence as a chemist in 1832. Since that time forensic science and evidence has come a long way in various ways and technology to help in determine if the suspect is guilt or not, through such things as DNA testing, blood, and fingerprints. The first forensic police crime lab was created in 1910. The contributions of Dr. Edmond Locard, a French scientist and criminologist, proposed that “everything leaves a trace”. This principle is still valid today as it was so many years ago. No matter how small, the specialized trained technicians and investigators can take these methods and go to a crime scene to get evidence. “Forensic science is the application of sciences such as physics, chemistry, biology, computer science and engineering to matters of law.” (Office of Justice, 2017) These different sciences can help achieve and assist in solving a case. Forensic science has also the ability to prove that a crime was committed, it can find the elements of the crime, it can help place the suspect at the scene and whether the suspect had any contact with the victim. However, in the last several years the techniques and with the use of technology the evidence that forensic science uncovers can also exonerate an innocent individual who has been falsely accused of the
The process of gathering evidence largely depends on the role of discretion by the police. Once police have decided to pursue a reported crime, they then begin the process of gathering evidence. To ensure that the process of gathering evidence is lawful, the police must follow the procedure outlined in the Evidence Act 1995 (NSW), which describes the manner in which evidence can be collected. This act imposes certain limits on the way police can gather evidence and the types of evidence that can be used. The Act is able to protect the rights of citizens by making it a requirement for the police to gain necessary legal documentation, such as search warrants, in order to obtain some types of evidence and thus, protects the rights of ordinary systems. In more recent times, the use of technology has come to play a major role in the gathering of evidence and with this comes complications in the law. New technologies in relation to the criminal investigation process are mainly in reference to DNA evidence, genetic material that can place a suspect at the scene of a crime. The introduction of DNA evidence into the criminal investigation process has been extremely effective in achieving justice, as it is able to secure convictions. Initially, there were some setbacks to the use of DNA evidence
