Document Summary

To solve problems, you have to access info already in your brain. Semantic networks - concepts are organized in mind in terms of connected ideas. Parallel to how info might be stored in a computer. Links can be shorter for closely related ideas, or longer for less related ideas. First semantic network model was hierarchical higher order to lower order categories: ex. Animal -> bird -> ostrich: more specific characteristics like sings, long legs, stored at lower nodes. Can breathe at higher nodes: longer it takes us to verify connection between nodes longer it takes for us to make that link. People verify pig is animal takes longer than pig is mammal. Therefore proposed modified semantic network: rather than hierarchical, says every individual semantic network develops based on experience and knowledge, means all ideas in head are connected together. When you active one concept, pulling related concepts with it.
