A9.16
Cognitive offloading and external representation
Cards in this group · 4
- A9.16.1External representation moves computation and comparison onto the interface, cutting mental arithmetic and tracking load
- A9.16.2Visualization turns numeric relationships into directly perceivable shape and position, replacing symbolic computation
- A9.16.3An external representation needs to match the internal cognitive process it serves, or the mismatch adds a translation cost
- A9.16.4Relying on external representation weakens internalized understanding of the underlying data relationships, trading learning for load
