Memory representations (schemas) that enable efficient coding of long- term memories; only the most significant details of a given life event need to be encoded as upon retrieval the event is reconstructed based on schema-based general knowledge and the few significant details associated with the event. Similarly, the relevant knowledge, in the form of schemas, is activated when planning ahead and organizing behavior in pursuit of specific goals. Indeed, it is good to bear in mind that the primary purpose of memory is to help make sense out of the world and predict what will happen next due to actions that one is about to take.
