Problem: Think of 3-5 different categories (e.g., dog, furniture, emotion, etc.). Provide a definition for each category. What are the properties for each that you think are important for category membership? Are each of the properties necessary for category membership (i.e., must every member of the category possess this property?)? Are each of the properties sufficient for category membership (i.e., must anything that possesses these properties necessarily be a member of the category)? Was this assignment difficult or easy to do? Why?
