Has a large capacity. Memory structures called schemata are the basis for problem solving and inferences. Management of cognitive load - Information in WM is perishable. It decays rapidly without rehearsal - The storage capacity of WM is small. Chunk size is a function of experience.
Experts form apparently larger chunks of information than novices.
Experts are believed to have a greater WM capacity. If learners are overloaded, the rehearsal process requires that WM capacity will be disrupted, and learning will be impeded.
