Question | Answer |
---|---|
back propagation | process where learning occur in a connectionist network, an error signal is transmitted backward thru the network. backward-transmitted error signal provides info needed to adjust weights in the network to achieve the correct output signal for a stimulus |
basic level | Rosch's categorization scheme, level below global (superordniate) level ("table" for superordinate "furniture"). basic level is psychologically special b/c it is level above which much info is lost and below which little is gained |
categorization | process by which objects are placedin categories |
category | groups of objects that belong together b/c they belong to the same class of objects ("houses", "furniture" or "schools") |
category-specific knowledge impairment | result of brain damage in which the patient has trouble recognizing objects in a specific category |
cognitive economy | feature of some semantic network models which properties of category are shared by many membersof category are stored at higher level node in network. ("can fly" stored at node for "bird" rather than "canary") |
