There are many interesting knowledge that I learned about in this psychology class, that will help me a lot in the future. If I have to decide on one, I would say that one of the most useful things I learned in class was in the lectures about Memory. In class, we learned about different mnemonic techniques such as visualizing, the key word method, method of loci, and narrative technique. All the mnemonic techniques were pretty useful, but the method of loci (locations) was the one that I think will especially help me in the future. Method of loci is good for remembering a speech you have to do. First you memorize a sequence of objects, and then think of somewhere you know very well. And then imagine walking through the roads, and put the objects at places in the road/street/room. Visualize that image such as a window and correlate it with the point you want to make. This technique, I think will help me very much in the future, in presentations and speechs. Next semester, I'm going to be taking a public speaking class, and I'm going to use the method of loci all the time!
If you're worried about public speaking and giving speeches, you might also want to look over the part of the book that copes with stress. But all joking aside, remembering these little tricks to help you remember other things, like speeches, will definitely put you farther in the world. Being able to prove yourself intellectually beyond your coworkers will help you with the promotion, and of course in your public speaking course will help you with your grade. In any case, good luck next year!
