Textbook Question
Chapter 39.5, Problem 1CT
At least two commercial companies, No Lie MRI and Cephos, are trying to develop fMRI into a lie detector. Conventional lie detectors (polygraphs) measure breathing, blood pressure, pulse, and sweating. On the principle that lying is stressful, the expectation is that a liar will show faster breathing and pulse, higher Mood pressure, and more sweat. The U.S. National Research Council found that polygraph tests are about 80% to 90% accurate: much better than chance, but far from perfect. In addition, many people can teach themselves to remain calm while lying and fool lie detectors. The idea of using fMRI for lie detection is intriguing because brain activity is very likely to differ if someone is telling the truth or telling a lie. Assuming that fMRI can be applied to lie detection, what level of accuracy do you think should be required before fMRI is allowed as evidence in the courtroom? What about people who might be especially skilled at lying or who seem to be unable to distinguish (or care about) truth and lies?

For each measure below, indicate which kinds of reliability would need to be evaluated. Then draw a scatterplot indicating that the measure has good reliability and another one indicating the measure has poor reliability.Â
C. Psychologists measure how long it takes a mouse to learn an eyeblink response. For 60 trials, they present a mouse with a distinctive blue light followed immediately by a puff of air. The 5th, 10th, 15th trials are test trials, in which they present the blue light alone(without the air puff). The mouse is said to have learned the eyeblink response if observers record that it blinked its eyes in response to test trials. The earlier in the 60 trials the mouse shows the eyeblink response, the faster it has learned the response.

- What is NOT a limitation of functional magnetic resonance imaging? Group of answer choices 1.The fMRI technique has poor resolution in comparison to other techniques. 2.Research using fMRI is more exploratory than hypothesis-based. 3.Many fMRI results are not stable across time and/or are due to chance. 4.Conclusions from fMRI results are often exaggerated and oversimplified.arrow_forwardA researcher has designed a card choice task to better understand altered decision making in a group of patients who have sustained damage to their ventromedial prefrontal cortex (compared to a non-damaged control group). Participants complete 120 trials. On each trial they choose to flip over a card from one of two decks of face down cards labeled deck 1 and deck 2. Each card flipped over wins or loses an amount of money. In deck 1 (the “bad deck”), 9 out of 10 cards wins $100 but one out of ten cards loses $1250. In deck 2 (the “good deck”), 9 out of 10 cards wins $50 and one out of ten loses $250. The researcher measures the number of choices from the “good deck” versus the “bad deck”, and measures anticipatory skin conductance responses immediately before participants choose from the “good deck” compared to the “bad deck”. The research finds that after experiencing wins and losses from 60 choice trials, control group participants on average begin to choose the “good deck” more…arrow_forwardIn the Posner cueing paradigm, the participant maintains fixation at the central point. Cues indicate whether the target will appear on the left or the right. In most trials, the cue is valid; that is, the target appears on the indicated side. But in some trials, the cue is invalid; that is, the target appears on the opposite side of the cue. The experimenters measure the reaction time to indicate that the target is present. The results show that ______.  Question 58 options:  participants are relatively faster when the cue is invalid  reaction time increases for valid trials  participants are relatively faster when the cue is valid  maintaining fixation reduces reaction time significantly The Chan Shun concert hall in Vancouver has excellent acoustics.

- In double-blind studies neither the test subject or the researcher knows who was given the drug and who was given the control. Why are these studies effective for testing a drug that may elevate mood and relieve feelings of depression? Since there are two symptoms that are affected, a double-blind study is required. Double-blind studies are ways to ensure that only the researcher can figure out who is getting the effective drug. Double-blind studies are the most economical way to gather results from testing on humans. The patients and researchers are not given this information so they cannot be influenced in reporting the effectiveness.arrow_forwardwhat is the steps taken to improve the risk of artificial intelligence in healthcare.arrow_forwardThe following is an excerpt from a discussion of Principlism, which we have studied. (https://www.encyclopedia.com/science/encyclopedias-almanacs-transcripts-and-maps/principlism) Consider, for example, the question of what health professionals should do when they discover that a patient infected with the human immunodeficiency virus (HIV) is having unprotected sex with partners who are ignorant of his condition. First, respect for the patient's autonomy supports a policy of medical confidentiality, requiring health professionals not to reveal to others private information discovered in the course of caring for patients. According to this policy, health professionals should do nothing to warn the sexual partners of their HIV-positive patient, as doing so would violate his confidentiality. Second, if there is evidence that public disclosure of the patient's condition would harm him economically, socially, psychologically, or physically, the principle of nonmaleficence would also urge…arrow_forward
