First, comprehenders lay foundations for their mental structures. Next, comprehenders develop their mental structures by mapping on information when that incoming information coheres with the previous information. So, most representations comprise several branching substructures. The building blocks of these mental structures are memory cells. Memory cells are activated by incoming stimuli.
Initial activation forms the foundation of mental structures.
Once the foundation is laid, subsequent information is often mapped on to a developing structure because the more coherent the incoming information is with the previous information, the more likely it is to activate similar memory cells. In contrast, the less coherent the incoming information is, the less likely it is to activate similar memory cells. In this case, the incoming information might activate a different set of cells, and the activation of this other set of cells forms the foundation for a new substructure. Memory cells are enhanced when the information they represent is necessary for further structure building. They are suppressed when the in formation they represent is no longer as necessary.
