Note: For the following questions, consider the following helpful instructions.It is not enough to simply provide a definition of the brain scans. You must clearly justify why the particular scan is to be used. Your answer Should be a two-part answer: How the scan works and why/how it would be useful for diagnosis. For example: “An MRI ………………….., therefore it would be helpful in evaluating Rico because……….. It is not enough to provide a definition/function of the brain structures. You must define the term, then clearly link it to the behavior. For example using the first prompt: The hypothalamus is found in the limbic system and plays a role in drives and urges. The hypothalamus is related to Rico’s behavior because he was hungry and thirsty and that caused him to go to the cafeteria for food. Feeling thirsty and hungry, Rico Suave decided to go to go to the school cafeteria. Along the way, Rico noticed someone who was “HOT”. He began to stare, and not looking where he was going, walked off the top step of a flight of stairs. Rico then tumbled down the stairs, hitting his head multiple times. Rico now has now recovered somewhat, but has a difficult time in school.Explain why AND how the following would be used to assess Rico’s condition right after the accident.MRIPET ScanExplain how each of the following is related to Rico’s behavior. HypothalamusEndocrine SystemAssuming each of the following were damaged in Rico’s fall, explain how each might now affect Rico in school. Pre-frontal cortexOccipital LobeMotor CortexHippocampusMr. Gorski graded essays, notebooks and other assorted assignments for 7 hours straight – when his wife found him mumbling (more than usual) incoherently. Over and over he stammered “Its interesting because its interesting.” Ha, ha, ha.” I never knew that before.” Ha, ha, ha. She promptly called for an ambulance and Mr. Gorski was taken to the hospital. When evaluated, his symptoms included the following strange variety: Mr. Gorski claimed to taste colors, his speech was difficult to comprehend, he had a high threshold for pain, he had a difficult time walking and playing his accordion at the same time, he could not seem to fall asleep and activities like crushing stupid cell phones no longer seem to bring him pleasure. Explain why AND how each of the following might be used to assess Mr. Gorski’s condition. fMRICT ScanExplain in what way each of the following may be contributing Mr. Gorski’s condition. CerebellumThalamusSubstance PReticular formationDopamineLeft hemisphereIn a cruel twist of fate, after many years of being exposed to scented markers, Mr. Gorski began to exhibit many strange side-effects. These included: impatience at spirit count; his left hand suddenly going numb; forgetting to play DVTV; an inability to keep his mouth shut regarding his frustration over rally days, PSAT, and all the other strange things that cut into curriculum; not being able to read, suddenly, when the calendar for meetings and staff development is released; and unusual burst of joyousness when a young scholar asks a good question.Explain why AND how each of the following might be used to assess Mr. Gorski’s condition.EEGCT ScanSpecific to Mr. Gorski’s situation, explain how each of the following seems to have been affected.HippocampusParietal LobeAmygdalaFrontal lobeRight hemisphereDopamineA researcher was interested in the effects of food on hyperactivity. To test their hypothesis, the researcher used an elementary class with students aged 4-5. As students entered the classroom, they were sent to one of three classrooms. The first third to enter their home classroom were sent to a classroom where they were given sugary snacks; the second third were sent to a classroom where they were given fresh vegetables; and the last third were sent to a classroom where they were not given anything to eat. Hyperactivity was then measured by how often children left their seats during the half-hour in which they were in the classroom.Identify the two levels of the independent variable.What is the operational definition of the dependent variable?Explain whether or not random assignment was used in this study.A psychologist conducted a study at her home during an annual activity of children wearing masks and going door-to-door receiving candy. Some of the children arrived alone, while others arrived in a group. During the first hour of the study, the psychologist asked half of the children to remove their masks when they arrived at der door. During the second hour, children kept their masks on. The psychologist told every child to take only one piece of candy. She then went inside the house, leaving the bowl of candy outside. This gage children the opportunity to take additional candy. The psychologist measured the percentage of children who took additional candy.Identify the two independent variables.Identify the operational definition of the dependent variable.Explain whether or not random assignment was used. ................
