How does PET scan work? State how they are different from MRI and functional magnetic resonance imaging (fMRI). Why is radioactively labeled glucose often used as a metabolic tracer? What does it mean if glucose is being absorbed or used in one area more than another?PET scans expose the body and brain to the radioactive chemicals to identify brain activity (Kalat, 2018 p94). The MRI on the other hand uses scans and images to capture brain function. When there is too much glucose in the blood it is called hyperglycemia.What are neural networks, and how do neural networks relate to localized and global brain functioning? What does our knowledge of neural networks tell us about how the brain processes information? How do PET scans and fMRI allow us to see the flow of information throughout networks?Neural networks refer to the network of processes the body uses to copy bodily function. This allows for recognition between different data sets (Sharma, 2021). Neural networks show that the brain recognizes and categorizes different experiences t be used in the future. These processes work in that they show blood and oxygen routes in the brain as they should be and over time.Do people only use a small percentage of their brain? Use what you know about neural networks and functional imaging scans to address this belief. Do you believe that we only use 10 percent of our brain capacity? Would someone be able to demonstrate via various cognitive tasks that no part of the brain sits in the cranium unused?According to Kendra Cherry (2020), we use all of our brain unless trauma or other reasons prevent us from doing so. By using these machines and knowing how neural networks work, researchers can determine how and when certain areas are in use. To know this, during a scan, the part of the brain that is in use lights up for measurement and recording. Brain compacity is different. I feel that we cannot use that much of our brain to its full compacity because we do not know how. This can be demonstrated using the before mentioned medical machines.ReferencesKalat, J. W. (2018).

In your unit readings from the Psychological Testing and Assessment text, you read about three sources of error variance that occur in testing and assessment. These include test construction, test administration, and test scoring and interpretation. Additionally, other sources of error may be suspect. You were also introduced to reliability coefficients, which provide information about these sources of error variance on a test (see Table 5-4).The following reliability coefficients were obtained from studies on a new test, THING, purporting to measure a new construct (that is, Something). Alternate forms of the test were also developed and examined in subsequent studies published in the peer-reviewed journals. The alternate test forms were titled THING 1 and THING 2. (Remember to refer back to your Psychological Testing and Assessment text for information about using and interpreting a coefficient of reliability.)Internal consistency reliability coefficient = .92Alternate forms reliability coefficient = .82Test-retest reliability coefficient = .50In your post:Describe what these scores mean.Interpret these results individually in terms of the information they provide on sources of error variance.Synthesize all of these interpretations into a final evaluation about this test’s utility or usefulness.Explain whether these data are acceptable.Explain under what conditions they may not be acceptable and under what conditions, if any, they may be appropriate.

1. How might workplace sexism impact women’s health physically and/or mentally and have you ever been effected by it.2. In what type of industries is workplace sexism more likely to occur and why then explain which industries workplace sexism might be LEAST likely to occur.

PSYC431 W3: BPS Reactions to Disasters

/in /by

In review of our course materials this week, we are introduced to several excellent theories aiding our understanding in the survivors’ experience in coping after disaster events. The complex nature of disasters results in reactions manifested in many ways including psychological, biological, and social. The architect of modern-day positive psychology, Dr. Martin Seligman, speaks to the foundational basis of the psychological approach in his Ted Talk, The New Era of Positive Psychology. In considering the insights Dr. Seligman applies to the field of psychology, we may find useful applications to addressing concerns unique to disaster psychology.After reviewing the course materials for the week, including Dr. Seligman’s Ted Talk, share the theory or psychological approach to coping after a disaster event that most stood out to you as effective in aiding survivors and the rationale for your selection.In addition, considering the Core Actions of Psychological First Aid (PFA) we have reviewed thus far, discuss the appropriateness of implementing any or all Core Actions in conjunction with the selected theory or approach.ReferenceSeligman, M.
