Question 1

An increase in the electrical conduction of the skin indicates an increase in sweating,which in turn indicates

Accepted Answer

An increase in sweating is regulated by the sympathetic nervous system. Therefore, an increase in electrical conduction of the skin would indicate an increase in activity of the sympathetic nervous system. Choice A is incorrect because the parasympathetic nervous system does not regulate sweating. Choice C is incorrect because a decrease in activity of the sympathetic nervous system would result in decreased sweating. Choice D is incorrect because insulin does not regulate sweating.

Question 2

A common way of measuring someone's level of fear or anxiety is by measuring

Accepted Answer

Changes in the startle reflex to a sudden sound is a well-established and reliable way to measure fear or anxiety levels. This is because the startle reflex is an automatic response to a sudden, unexpected stimulus, and it is heightened in individuals with higher levels of anxiety or fear. Measuring the magnitude of the startle reflex in response to a sudden sound can provide objective information about a person's level of fear or anxiety. Measuring blood flow to the brain, changes in concentration, or speech patterns can also provide useful information, but they are not as commonly used nor as straightforward as measuring the startle reflex.

Question 3

Activity of the sympathetic nervous system increases the electrical resistance of the skin by increasing:

Accepted Answer

Sweating increases the electrical conductivity of the skin, so if the sympathetic nervous system increases sweating, it would decrease the electrical resistance of the skin, not increase it. On the other hand, when the sympathetic nervous system is activated, it causes constriction of blood vessels in the skin, which reduces blood flow and secretion of sweat glands. This increases the electrical resistance of the skin, making it more difficult for electrical current to pass through. Therefore, the correct answer is A) sweating.

Question 4

Electrical conduction of the skin provides an indication of the level of activity of the

Accepted Answer

Electrical conduction of the skin, also known as electrodermal activity, is primarily controlled by the sympathetic nervous system. This system regulates the body's response to stress and arousal, causing increases in sweat gland activity and subsequently, electrical conductivity of the skin. Therefore, the level of electrical conduction of the skin can provide an indication of the level of activity in the sympathetic nervous system.

Question 5

Joan,who suffers from an anxiety disorder,is having a conversation with June,who does not suffer from an anxiety disorder.Suddenly there is a loud,unexpected noise.Which of the following is most likely to occur?

Accepted Answer

Individuals with anxiety disorders have been found to have a heightened startle response, which means they are more likely to be startled by sudden noises or unexpected events. Therefore, it is most likely that Joan will show a greater startle response to the noise than June.

Question 6

The polygraph test is based on the assumption that when people tell lies,

Accepted Answer

The polygraph test is based on the assumption that when people tell lies, their heart rate and breathing rate increase. This increase in physiological arousal is what the polygraph machine detects to indicate potential deception. Eye movements and hand twitches are not reliable indicators of lying, and may be influenced by other factors such as stress or nervousness.

Question 7

When polygraph examiners administer polygraph tests in order to detect lying

Accepted Answer

Research has shown that polygraph examiners can often detect when someone is lying, but they also frequently make false positives - reporting honest individuals as lying. This is due to the fact that the polygraph measures physiological responses that can be influenced by factors other than deception, such as anxiety or stress. Therefore, while polygraphs may have some utility in certain settings, they are not foolproof and should not be relied upon as the sole determinant of truthfulness.

Question 8

The polygraph test measures

Accepted Answer

The polygraph test measures the activity of the sympathetic nervous system, which is responsible for the "fight or flight" response in humans. This response is associated with physiological changes such as increased heart rate, breathing rate, and sweat production. The polygraph test measures these changes to determine if a person is being truthful or deceptive.

Question 9

The theory behind the polygraph test is that people who are lying

Accepted Answer

The theory behind the polygraph test is that people who are lying have increased activity of the sympathetic nervous system, which leads to increased heart rate, blood pressure, and respiration rate. These physiological changes can be detected by a polygraph machine.

Question 10

In addition to self-report measures,researchers operationally define anxiety as

Accepted Answer

An increase in the startle reflex is an objective measure of anxiety that can be operationalized and measured in a laboratory setting. This measure assesses the physiological response to a sudden, unexpected stimulus, which is increased in anxious individuals. While the other options may be subjective experiences of anxiety, they are not necessarily measurable or operationalized in a consistent way.

Question 11

Results from one research study suggested that professional polygraph administrators were able to identify __________ of the guilty suspects as liars but also classified __________ of the innocent suspects as liars.

Accepted Answer

Research on polygraph accuracy often shows that while polygraph administrators can identify a significant portion of guilty suspects correctly, they also have a notable rate of false positives, where innocent suspects are incorrectly identified as liars. The figures 76% and 37% reflect a scenario where a majority of guilty suspects are identified, but a substantial minority of innocent suspects are also misclassified, which aligns with the performance characteristics of polygraphs in some studies.

Question 12

The polygraph test is based on the assumption that when people lie,they will show an increase in

Accepted Answer

The polygraph test measures physiological responses such as heart rate, breathing rate, and sweating, all of which may increase when a person lies. There is no evidence to suggest that lying is associated with increased blood flow to the prefrontal cortex, digestive activities and salivation, or specific muscle movements in the hand and foot.

Question 13

In general the research on our ability to detect lies finds that

Accepted Answer

The research on our ability to detect lies suggests that most people are no better than chance (50%) at detecting lying. While some studies have found that certain groups, such as those with training in deception detection or law enforcement experience, may perform better, there is no consistent evidence to suggest that any specific gender or demographic group is consistently better at detecting lies.

Question 14

According to research on the polygraph test,its major flaw is that

Accepted Answer

Research has shown that the polygraph test is not reliable in identifying liars and also has a high rate of false positives, meaning it often identifies honest people as liars. This is its major flaw.

Question 15

Question 16

The polygraph test measures

Accepted Answer

The polygraph test, commonly known as a lie detector test, measures the subject's physiological responses, including changes in heart rate, breathing rate, and electrical resistance of the skin. These responses are believed to indicate a person's level of stress and can be used to infer whether or not the subject is telling the truth. The test does not measure hand tremor, handwriting, facial expressions, voice stress levels, or the level of stress in the voice.

Question 17

The polygraph test measures

Accepted Answer

The polygraph test measures the activity of the sympathetic nervous system, which is responsible for the fight or flight response. This is detected by changes in physiological responses such as heart rate, blood pressure, and sweating.

Question 18

Researchers measure changes in the startle reflex as an operational definition of

Accepted Answer

The startle reflex is a physical response that is often heightened during states of anxiety or fear. Therefore, researchers using the startle reflex as an operational definition are most likely studying anxiety.

Question 19

All of the following brain structures are active in regulating the startle response EXCEPT the

Accepted Answer

The primary motor cortex is primarily responsible for movement and control of voluntary muscle activity, and is not directly involved in regulating the startle response. The other three brain structures listed are all known to play a role in the startle response. The medulla and pons are part of the brainstem, and are involved in coordinating basic physiological functions like breathing, heart rate, and reflexes. The amygdala, located in the temporal lobe, is involved in the processing of emotional and fear-related stimuli, and has been shown to modulate the acoustic startle response.

Question 20

The main objection to the polygraph test is that

Accepted Answer

The main objection to the polygraph test is that it incorrectly identifies too many honest people as liars. This is due to the fact that the polygraph measures physiological responses that could be caused by a variety of factors, not just deception. Therefore, innocent individuals may experience anxiety or stress during the test, leading to an incorrect identification as a liar.
