Psychological and Neurobiological Validity of Subsumption

Although Brooks identifies no particular species for the agents that have been built within the subsumption architecture, the ideas behind the architecture were inspired by insects. Specifically, Brooks contends that the model was inspired by a consideration of evolution, that nature built increasingly complex agents that all interacted in the complex and dynamic world. Furthermore, the distributed organization of the architecture, activation spreading, and network concepts all have biological feasibility.

Hormonal Activation

The process Brooks describes for regulating goal interaction was based on hormonal activation in lobsters.

Planning and Learning Example

Mataric says that the distributed spatial representation, map learning, and the planning architecture itself are consistent with the physiological data taken from rat navigation tasks. Additionally, the landmark finding procedure is based on principles of human landmark identification and navigation.
