PSY 105 Having Our Heads Examined NEW QUESTIONS AND ANSWERS SOLUTION 2021 What are the two broad categories of brain imaging techniques? Structural and Functional Imaging Magnetic and Electric Imaging X-ray and 3-D Imaging Modular and Custom Imaging For which purpose would structural imaging techniques most likely be used? diagnose the foci of epileptic seizures identify parts of the brain that must be kept intact during surgery measure activity in certain parts of the brain locate a blood clot or tumor on the brain Save Liz has just completed her third round of chemotherapy and radiation. Which brain imaging technique might her doctor use to monitor her progress? MEG EEG CT scan PET Save As detected by the MRI scan, to what is the intensity of magnetic resonance proportional? percentage of activity in the tissues percentage of glucose in the tissues percentage of blood in the tissues percentage of water in the tissues Save Which of the following is true of diseased or damaged tissues? They contain more glucose. They get more blood flow. They contain less water. They contain more water. Save What do the “lit up” areas of fMRI reveal? where there is decreased blood flow where there is increased neuronal activity where there is decreased neuronal activity where there is damaged tissue Save Which brain imaging technique records the oscillations of the brain’s neurons? EEG MRI fMRI PET Save Which type of braining imaging would be used for sleep studies? fMRI PET scan EEG MEG Save Brain Imaging: A Tool for Psychological Research In Dr. Decety's study, what did fMRI scans reveal about the way children respond to images depicting pain? Child brains and adult brains respond similarly to images of pain. Very few children are developed enough to form moral judgments when viewing images of pain. Young children respond with greater empathy than older children when seeing images of pain. Children respond with less empathy than adults when seeing images of pain. Save In the brains of children shown images of someone being intentionally hurt, the areas that “lit up” in the fMRI scans are involved in which of the following processes? social interaction and moral reasoning language and learning reason and linear thinking vision and facial decoding Save Which of the following is NOT revealed by PET scans of people with Schizophrenia? structural defects in certain brain regions lower levels of glucose metabolism abnormalities in certain neural pathways higher levels of glucose metabolism Save What parts of the brain are involved when schizophrenics fail to connect the proper emotion to the proper circumstance? cingulate gyrus and parietal cortex parietal cortex and frontal cortex hippocampus and cingulate gyrus thalamus and cortical areas Save What parts of the brain are involved when schizophrenics show deficit symptoms such as reduced social interaction? cingulate gyrus, and the frontal and parietal cortex hippocampus and thalamus and frontal cortex thalamus and the frontal and parietal cortex hippocampus and cingulate gyrus and parietal cortex Save How was the selection of subjects in the Duffy & Als study different from many other Autism studies? They included both children and teenagers with Autism. They excluded children with other illnesses, but included those with genetic syndromes. They mainly included children with “high-functioning” Autism. They excluded children with "high-functioning" Autism. Save According to the final article, how are researchers hoping to use EEG scans in the future? to diagnose Autism to teach children with Autism to talk to alter the gene that predisposes children to Autism to cure Autism
