Question 1

The technique that uses systematic analysis of written statements to assess the credibility of accounts related to a particular event is called:

Accepted Answer

Criteria-based content analysis (CBCA) is a technique used to evaluate the truthfulness of written or verbal statements by analyzing their content against psychological criteria. It is often used in forensic psychology to assess the credibility of eyewitness accounts or testimonies.

Accepted Answer

The answer of Some promising low-tech methods of lie detection...

Question 3

_____ measures almost imperceptible changes in the heat of the human face.

Accepted Answer

High-definition infrared thermal imaging is used to detect minute changes in heat, including those on the human face, which can be useful in various applications such as medical diagnostics and security.

Question 4

When jurors are presented with polygraph evidence, they:

Accepted Answer

Jurors often take polygraph evidence seriously, despite its questionable validity, because they may perceive it as scientific and objective.

Question 5

According to a study conducted by Honts and colleagues (1994), the use of countermeasures _____ the detection of guilty suspects by 50%, and the examiners _____ able to tell that the suspects were manipulating their own arousal patterns.

Accepted Answer

The study by Honts and colleagues (1994) found that the use of countermeasures reduced the detection of guilty suspects by 50%, and the examiners were not able to tell that the suspects were manipulating their own arousal patterns.

Question 6

According to the text, when police use the polygraph, it is usually done for the purpose of:

Accepted Answer

The answer of According to the text, when police use...

Question 7

According to the text, even though fMRI is a promising technique, it has multiple serious limitations. Which of the following is not one of these limitations?

Accepted Answer

The fMRI machine is not highly portable, which is not listed as a limitation in the text. The other options (A, C, D) are mentioned as limitations of fMRI technology.

Question 8

The guilty knowledge test (GKT) is one of the most promising polygraph techniques to date. However, there are some limitations to its usefulness. Which of the following is one of the main limitations of GKT?

Accepted Answer

The main limitation of the Guilty Knowledge Test (GKT) is that it requires a sufficient number of crime facts that are uniquely known only by the criminal, which is often not available. This makes it challenging to create effective test questions that can reliably indicate guilt.

Question 9

According to the text, the actual level of accuracy of polygraph techniques is likely:

Accepted Answer

The actual level of accuracy for polygraph techniques is widely debated among experts, but most studies suggest it falls somewhere between 50% and 90%. This range accounts for various factors, including the skill of the examiner, the type of questions asked, and the specific circumstances of the polygraph test.

Question 10

Elena was suspected of committing a fraud. Investigators asked her to tell her story in reverse. This promising lie-detection technique is based on the idea that narrating backwards:

Accepted Answer

Narrating a story in reverse order increases cognitive load, making it more difficult for someone to maintain a fabricated story, thus potentially revealing inconsistencies or signs of deception.

Question 11

The guilty knowledge test (GKT) uses a multiple-choice question format. When a suspect provides the answers, _____ is usually _____.

Accepted Answer

The answer of The guilty knowledge test (GKT) uses a...

Question 12

According to the text, EEG reads neural impulses _____, whereas fMRI reads brain activity _____.

Accepted Answer

EEG (Electroencephalography) measures electrical activity in the brain continuously, providing real-time data. fMRI (Functional Magnetic Resonance Imaging), on the other hand, measures brain activity by detecting changes associated with blood flow, and it does so in intervals, not continuously, but the specific interval of "every 1.5 seconds" is a simplification for the purpose of this question.

Question 13

Which of the following statements correctly reflects the current legal status of the polygraph?

Accepted Answer

The legal status of polygraph tests varies significantly across different jurisdictions within the United States. While not universally banned, their admissibility in court is often subject to significant restrictions or skepticism, with almost half of the states imposing limitations on their use in court proceedings. This reflects a general caution in the legal system regarding the reliability of polygraph results.

Question 14

The rates of accuracy of the polygraph have been calculated using controlled lab studies and mock crimes. These rates are likely to be somewhat inflated for the following reasons, EXCEPT:

Accepted Answer

The rates of accuracy of the polygraph would not be inflated due to the use of outdated machines; instead, this factor could potentially decrease accuracy or have no effect on the reported rates.

Question 15

The _____ shows a video image of the brain in action.

Accepted Answer

The fMRI (Functional Magnetic Resonance Imaging) shows a video image of the brain in action by measuring brain activity through changes in blood flow.

Question 16

Techniques such as biting one's tongue, pressing one's toes to the floor, or counting backwards are all examples of:

Accepted Answer

These techniques are countermeasures to polygraph testing, designed to help individuals control their physiological responses and potentially skew the results.

Question 17

The polygraph may be used as a _____ tactic to evoke _____.

Accepted Answer

The polygraph, or lie detector test, is often used as a coercive tactic by investigators to pressure a suspect into confessing, by suggesting that the machine can detect lies with certainty.

Question 18

Marissa is being polygraphed using the guilty knowledge test (GKT). This test focuses on whether Marissa:

Accepted Answer

The guilty knowledge test (GKT) is designed to determine if the person being tested knows specific details about a crime that would only be known to the perpetrator, hence option B is correct.

Question 19

Among the techniques looking at brain activity patterns, _____ is better able to locate the precise area of the brain activity, whereas _____ is better able to determine the timing of the activity.

Accepted Answer

fMRI (Functional Magnetic Resonance Imaging) is better at locating the precise area of brain activity due to its high spatial resolution. EEG (Electroencephalography), on the other hand, excels in determining the timing of brain activity because it has high temporal resolution.

Question 20

Unlike other polygraph tests, the guilty knowledge test (GKT):

Accepted Answer

The guilty knowledge test (GKT) is designed to detect if the person being tested knows details about a crime that only the perpetrator would know, without relying heavily on the subjective interpretation of the polygraph examiner. This approach minimizes the examiner's role in interpreting results, effectively reducing them to the role of technicians who administer the test rather than experts who interpret complex physiological responses.
