Answer:    The principle of continuity
Explanation:  The Gestalt Continuity Law refers to how the human brain perceives the line-elements that are grouped. Continuity theory refers in fact to the tendency of the brain to see the constituent elements as a whole, that is, the elements belong to a whole, a continuous representation of something.  In this case, the brain of little Sinead perceived that all the elements that are part of the exhibit snake make up the whole, and with the perception of the brain, they continue into the living snake. 
The essence of this theory is that, for example, the line is perceived as a continuation of some imagined, established direction.
