# Name of association phenomenon

What is the name of the problem to explain how the neural activation for "red circle and a blue triangle" is different from "blue circle and red triangle"? Just activating the neurons for "red", "blue", "circle", "triangle" is not enough.

$V = BLUE*CIRCLE + RED*TRIANGLE$
Where each word is it's own N-dimensional vector, $+$ is vector addition and $*$ is circular convolution.
