Document Summary

Knowledge is interconnected, we are storing knowledge in an interconnected network. One piece of information is connected to another piece of information. A category is a group of objects that belong together and have something in common. An exemplar is an item in the category. Ex: in the dog category, a german shepherd or poodle is an exemplar in that category. Categories allow us to predict what is likely in new situations because they treat all exemplars as similar. A concept is representation in our minds of that category. Created by humans as we need them (e. g. , hammers, computers) We do not have a set category for this, but can easily come up with a different category if we"re going to the beach vs. ski trip. Categories are defined by a list of necessary and sufficient features. Necessary: an item must have all defining features to be included in the category.
