2006 exam question 6 and 44 multi choice

Hi guys,

I didn't quite understand how the image in question 6 could be registered in both eyes, when one eye is covered (even if it is in the middle). with question 44, how is the experimenter's bias stopped when an assistant collects the data if the experimenter already encourages the experimental group during the experiment.

6. Remember the left half of each eye goes to the left hemisphere, and the right half of each eye goes to the right hemisphere. Since the image is projected in the MIDDLE of the visual field, the left half of his left eye will go to the left hemisphere , and the right half of his right eye will go to the right hemisphere. Thus, both occipital lobes.

44. I agree , so i dont know.

Thanks. also, with PET scans, what radioactive substance in the bloodstream is detected? does the radioactive injection actually cause different things in the blood to become radioactvie aswell (such as glucose)?

the brain itself runs on glucose, it takes up this injected glucose and the scanner tracks the rates of glucose consumption during specific active tasks

To "collect the data" is to perform the experiment. The experimenter has no contact with the E group.
