Question 1

The following behavioral clues are a reliable indicator that the person is lying:

Accepted Answer

None of the behaviors listed (A, B, C) are reliable indicators of lying on their own. These behaviors can be caused by a variety of factors, including nervousness, discomfort, or personal habits, and do not necessarily mean a person is lying.

Question 2

During the 1960s-1980s, polygraph use was:

Accepted Answer

During the 1960s-1980s, polygraph testing became a lucrative business, widely used in various sectors, including government agencies and private companies, for security screenings and employment processes.

Question 3

Paula has been playing with her fingers and rings during the interrogation and tried to avoid direct eye contact with her interrogator. Most people would mistakenly conclude that she is hiding something. This erroneous belief is called:

Accepted Answer

The liar's stereotype is the mistaken belief that certain behaviors, such as avoiding eye contact or fidgeting, are indicative of lying.

Question 4

There are several problems with standard polygraph techniques like CQT. Which of the following is NOT one of these problems?

Accepted Answer

The belief of polygraph examiners in the importance of their mission and skills is not considered a problem with standard polygraph techniques. The issues typically cited involve physiological responses, lack of standardization, and subjectivity in interpretation, not the examiners' belief in their work's importance.

Question 5

The comparison question test (CQT) polygraph technique utilizes comparison questions that are supposed to make a person uncomfortable (so called known lie questions). Which one of the following questions is NOT a good comparison question for CQT purposes?

Accepted Answer

Comparison questions in the CQT polygraph technique are designed to be emotionally provocative and to relate to the behavior being investigated, making the subject uncomfortable. Option B, asking about trying a food one did not like, does not fit this criterion as it is not emotionally provocative or related to dishonest or illegal behavior.

Question 6

Based on research studies of people's abilities in lie detection, the following statement is true:

Accepted Answer

Research has shown that police detectives do not perform significantly better than college students in lie detection tests, indicating that professional experience does not necessarily confer an advantage in this skill.

Question 7

One of the most important tasks of the polygraph examiner using the standard procedures like CQT is to:

Accepted Answer

The key task of a polygraph examiner, especially in the context of the Control Question Test (CQT), is to convince the examinee that the polygraph is infallible in detecting lies. This belief can influence the examinee's physiological responses, which the polygraph measures.

Question 8

When researchers assessed police detectives' ability to detect lies, they found the police to be _____ likely to correctly assess the truthfulness of videotaped statements compared with college students.

Accepted Answer

The answer of When researchers assessed police detectives' ability to...

Question 9

According to the text, the most prevalent use of the polygraph in the United States is:

Accepted Answer

The text indicates that the most prevalent use of the polygraph in the United States is for national security purposes, likely due to its application in government agencies for security clearances and investigations.

Question 10

According to the text, confirmation bias is one's tendency to:

Accepted Answer

Confirmation bias is the tendency to search for, interpret, favor, and recall information in a way that confirms one's preexisting beliefs or hypotheses.

Question 11

Jared was questioning a suspect using the Reid technique, and after a long and exhausting interrogation, the suspect falsely confessed to the crime just to put an end to the interrogation. When hearing this confession, Jared felt even more confident that the suspect was guilty. This is an illustration of the phenomenon that psychologists call:

Accepted Answer

Confirmation bias is the tendency to search for, interpret, favor, and recall information in a way that confirms one's preexisting beliefs or hypotheses, leading to statistical errors. In this scenario, Jared's increased confidence in the suspect's guilt after the false confession illustrates confirmation bias, as he interprets the confession as confirmation of his preexisting belief in the suspect's guilt, despite the confession being a result of a flawed interrogation technique.

Question 12

According to research completed by Bond and DePaulo (2006), people's ability to distinguish lies has a _____ above-chance rate of accuracy, and efforts to improve people's ability to discern lies have _____.

Accepted Answer

Research by Bond and DePaulo (2006) found that people's ability to detect lies is only slightly better than chance, and efforts to significantly improve this ability have generally not been very successful.

Question 13

The federal Polygraph Protection Act of 1988 prohibited the use of polygraph by:

Accepted Answer

The Federal Polygraph Protection Act of 1988 primarily prohibits most private employers from using lie detector tests, either for pre-employment screening or during the course of employment, with certain exceptions.

Question 14

A study by Kassin and his colleagues (2005) found that police detectives were _____ likely than college students to judge false confessions as true, and were _____ confident about their judgments.

Accepted Answer

Kassin and his colleagues (2005) found that police detectives were more likely than college students to judge false confessions as true, and were also more confident about their judgments. This suggests that expertise or experience in law enforcement does not necessarily protect against the misjudgment of confession validity.

Question 15

Our tendency to seek out information that supports our beliefs is otherwise known as:

Accepted Answer

Confirmation bias is the tendency to search for, interpret, favor, and recall information in a way that confirms one's preexisting beliefs or hypotheses.

Question 16

Training people to detect lies _____ their ability _____ their confidence in their ability to discern lies.

Accepted Answer

Research has shown that training people to detect lies does not significantly improve their ability to do so, but it often raises their confidence in their ability to discern lies.

Question 17

The comparison question test (CQT) posits that guilty individuals react more strongly to _____ questions, whereas innocent individuals react more strongly to _____ questions.

Accepted Answer

The CQT assumes that guilty individuals will have a stronger physiological response to relevant questions related to the crime, while innocent individuals will react more to comparison questions, which are designed to be emotionally provocative but unrelated to the crime.

Question 18

The basic theory behind the polygraph is that lying:

Accepted Answer

The basic theory behind the polygraph is that lying causes physiological arousal, which can be measured through indicators such as heart rate, blood pressure, respiration, and skin conductivity.

Question 19

Studies show that those police officers who have passed through interrogation training:

Accepted Answer

Studies indicate that while interrogation training can make police officers feel more confident in their lie detection abilities, it does not necessarily improve their actual accuracy in detecting lies. This overconfidence can be problematic because it may lead to a higher rate of false positives or negatives in lie detection.

Question 20

If a person is lying, the polygraph can pick up the following changes in his or her physiological functions, EXCEPT:

Accepted Answer

Polygraphs, also known as lie detectors, measure and record several physiological indices such as breathing, perspiration, and heart rate. They do not directly measure brain activity; technologies like fMRI or EEG are used for that purpose.
