When casey sees eight candies on the table that are placed like those

When Casey sees eight candies on the table that are placed like those below, she asks which two children get the candies.

How would a Gestalt psychologist explain Casey�s tendency to view the candy in two groups rather than as eight separate candies?

I know answer is  This is an example of the Gestalt principle of proximity.

   Objects that are near to each other tend to be grouped together.
   Thus, Casey sees two groups of candy rather than eight separate pieces of candy.

I simply need answer to be rewritten in 200 words or more and to include at least 1 reference
