What is the Dewey Decimal System and how does it work?
The Dewey Decimal System is a way to organize books and materials within a library so that they can be found easily. It is the standard used in most public and school libraries for non-fiction books (it used to be used for fiction, but that is usually shelved by author's last name). It works by grouping similar subjects together under a number, called a call number, which becomes an "address" of sorts for the items. The numbers start at 100 and go to 900, with each 100 representing a different subject. The number is the same across collections such as juvenile, young adult, or adult materials. For example, if you want books about dogs, the main call number is 636.7 in every nonfiction section of the library. Since all of the dog books are in the same place, it makes it easy to browse what you want. If you want a specific book, you will look at the letters after the number that identifies the author's last name. The book, Marley and Me, is located under 636.7527 GRO since the author's last name is Grogan.
What type of learning technique did Pavlov discover when studying salivation in dogs and how does it work?
He discovered classical conditioning, also called Pavlovian conditioning. It involves learning to associate an unconditioned stimulus that already causes a particular response or reflex with a new conditioned stimulus, which brings about the same response. Pavlov repeatedly used a metronome, which he presented to his dogs before he fed them (seeing food made them salivate) and eventually, just the metronome would make them salivate even though no food was presented.
