Feature comparison model (ripps, shoben & smith, 1973) developed to explain results that hierarchical. Network cannot explain all concepts in semantic memory represented as sets or lists of features no cognitive economy, same features stored with different concept. Feature comparison model (ripps, shoben & smith, 1973) Two types of features: defining features features essential to define concept e. g. , bird has feathers, has wings, characteristic features features that are characteristic or common to many members of category, but not essential e. g. , bird able to fly. Scaling similarity goose duck chicken pigeon parrot parakeet hawk eagle bird robin sparrow cardinal bluejay.
