Mental representations, after Ericsson and Pool

Ericsson and Pool (2016) use the term “mental representations” as vernacular shorthand for the chunking schema (“Chunks” in human cognition) a person uses in some domain (Efficient chunk schemas usually encode domain-specific attributes).

Mental representations matter because information processing capacity varies with their complexity. Human channel capacity increases with stimulus dimensionality and Human channel capacity increases with bits-per-chunk.

… mental representations … make it possible to process large amounts of information quickly, despite the limitations of short-term memory … one could define a mental representation as a conceptual structure designed to sidestep the usual restrictions that short-term memory places on mental processing.

(Ericsson and Pool, 2016, p. 61)
