Segmentation and accuracy in copying and drawing: Experts and beginners

As part of an ongoing investigation into real-world copying and drawing, I recorded the eye–hand drawing
strategies of 16 subjects with drawing experiences ranging from expert to novice while they copied a
line drawing of a standing nude. The experts produced accurate copies whereas all the beginners produced
marked inaccuracies of overall scaling, proportion and shape. Analysis of eye and hand movements
showed that the experts alone segmented the original drawing into simple line sections that were copied
one at a time using a direct eye–hand strategy not requiring intermediary encoding to visual memory.
The results suggest that segmentation into simple lines defines the task-specific process of accurate copying,
and that this process is restricted to experts, i.e. acquired through training and practice. Additional
preliminary tests also suggest that a similar process may apply to drawing a model from life.
