Document Summary
Chapter 9 concepts and generic knowledge (351 385) Proposed that members of a category have a family resemblance to one another to understand this, we think about an actual family. There are no features that every single person has, but there are features that are common in the family, so some attributes are shared. Prototype theory: this theory surrounds the idea that the best way to identify a category is to specify the center of the category, rather than the boundaries. There is 1 example that possesses all traits of every example that exists for that category. The ideal prototype will be an average of the various category members you have encountered. Graded membership: objects that are closer to the prototype are better members of the category than objects farther from the prototype. Research participants were presented with a series of sentences, and have to indicate whether each sentence was true or false.
