Abstract: A cognitive architecture uses hierarchically arranged modules to associate the computation of many expected attributes with a single concept. A first value stored in a first module represents a concept state. A second value stored in the first module represents an expectation state. The first module receives a third value that represents an input state. The first module has a lower hierarchy than a second module and a higher hierarchy than a third module. The first module provides the first value to the second module and the second value to the third module. The first value is computed using the third value and concept information stored in the first module. The second value is computed using the first value, the third value and expectation information stored in the first module. An actuated mechanism receives a signal derived from the second value, which influences an operation of the actuated mechanism.
