The scientists conducted other experiments in which they precisely measured where people look as they perform these tasks.
And they discovered that facial information is captured during a sequence of eye movements towards certain features of the cartoons, and the information is stored as spatial locations for subsequent eye and hand actions.
The drawing process then recreates these spatial features as the eye and hand are guided by the retained action plans.
Based on their observations, the researchers came to the conclusion that brain imaging, in combination with eye and hand tracking, can dissect complex visually guided tasks into separate functional stages.
The study is an important step towards a full understanding of how sensory information is used to guide actions.
The study has been published in the journal Cortex.
