Graphical Production of Complex Abstract Diagrams:Drawing Out Chunks and Schemas


What cognitive processes and strategies are used to reproduce complex abstract diagrams? Over ten sessions, a complex diagram was traced, copied, drawn immediately from memory and drawn after a delay. The five adult participants rapidly learned to make near perfect productions of the diagram. They converged on an approach that exploits chunks, which was used across all the modes of drawing, rather than a strategy that minimizes motor effort. They appear to use an overarching spatial schema to organize their access and production of the chunks.
