When asked to repeat the list during the PET session, each group was able to repeat the words perfectly without any differences. When it came time to repeat the new list of words, the users memorized more words from the end of the list than the beginning or middle. This showed that there was more blood flow in the area of the brain that controls short-term memory. In the overall number of words recited back to the scientists from the new list, there was no real difference between the two groups. The results showed that users relied more on their short-term memory rather than episodic memory. There was more blood flow in short-term memory regions of the brain. The nonusers used their working memory a lot more, which allowed them to memorize the list of words at a faster pace. The decrease of blood flow to longer-term memory regions can cause less efficient information processing.
I found it interesting that there wasn"t much of a difference between the users and nonusers. I expected the marijuana users to have a much greater difference in their ability to memorize and recall. I thought that the marijuana users would have to use more of their short-term region of the brain, but I didn"t expect the results to show very little difference between all of the subjects.
