This collection of terms includes (33) Which of the following is NOT a limitation of the present state of fMRI technology? C. A person must remain quiet within the fMRI scanner.
Similarly, Can fMRI be used to detect lies?
Despite some serious questions regarding its validity and reliability, fMRI lie detection might be useful in certain situations. This unprecedented capacity to see into someone’s thoughts creates serious ethical concerns.
Also, it is asked, What type of error is committed when an innocent suspect is misclassified as guilty?
The Coercion Mistake When investigators mistake an innocent person for a criminal suspect, they often interrogate him accusatorially.
Secondly, What is the purpose of using mock crimes in empirical studies about the polygraph?
Some individuals perform prepared “fake crimes” (such as stealing money from an office) in lie detection studies so that researchers may see whether a polygraph examiner can tell who committed mock crimes and who didn’t.
Also, What are some of the drawbacks to using a fMRI scanner as a lie detection device?
Researchers discovered that persons utilizing mental countermeasures may fool a functional magnetic resonance imaging (fMRI) ‘lying detector’ test, which examines brain activity. According to the findings, further research should be done to discover mental defenses before employing fMRI studies for forensic purposes.
People also ask, What are the advantages and disadvantages of fMRI?
The pictures produced by fMRI are exceptionally high quality and straightforward to utilize (as detailed as 1 millimeter). In addition, fMRI is significantly more objective than standard questionnaire techniques of psychological examination. However, there are certain drawbacks to fMRI. For starters, it’s costly.

Which of the following is a limitation of the fMRI quizlet?
One disadvantage of fMRI is that it does not provide a direct assessment of neural activity in specific brain regions since it detects changes in blood flow in the brain. This implies it’s not a true quantitative assessment of mental activity in these parts of the brain.
What is a major weakness of current functional neuroimaging techniques?
2002). When acquisitions are conducted in the resting state, one drawback of fcMRI is the confidence with which inferences about functional networks for particular cognitive or behavioral processes can be made. Techniques for addressing functional networks while doing relevant activities have recently been developed.
Is a type 1 error or Type 2 error worse?
The quick answer is that it depends entirely on the circumstances. A Type I error is better than a Type II mistake in certain situations, while in others, a Type I error is more risky to commit than a Type II error.

What is a Type 1 error example?
Type I Errors Examples Take, for example, the investigation of a suspected criminal. The null hypothesis states that the individual is innocent, whereas the alternative states that they are guilty. In this situation, a Type I mistake would result in the individual being judged guilty and imprisoned while being innocent.

What is a type I error quizlet?
Error type 1 (false positive) When we recognize that the difference/relationship exists and that we are incorrect. When a null hypothesis is true, it is rejected. Example of type 1. We reject a null hypothesis, which claims that a medicine has an impact on a condition when it really has none, and is thus untrue.

What is a Type 2 error in statistics example?
A type II mistake, also known as an omission error, results in a false negative. For example, a disease test may come back negative while the patient is really infected. This is a kind II mistake because we accept the test result as negative despite the fact that it is erroneous.
