The information held in the long-term memory store is central to all facets of human cognition just as the information held in a genomic store is central to the information processes necessary for evolution by natural selection. The immense size of these stores is necessary to enable them to function in complex natural environments. A natural information store must be sufficiently large to enable it to respond flexibly and appropriately to a very large range of conditions. In the case of human cognition, our long-term memory store is sufficiently large to enable the variety of cognitive activities, both biologically primary and secondary, engaged in by humans.
Novices need to use thinking skills. Experts use knowledge(contents of long term memory store)
In any biologically secondary area, we can expect the major, possibly sole difference between novices and experts to consist of differential knowledge held in long-term memory
