The spatial contiguity principle suggests that related information sources should be spatially integrated in order to reduce attention-splitting and facilitate learning.

An example of a solved mathematical problem taking into consideration and ignoring the spatial contiguity principle is presented in image on the right. Example A shows text and graph (two information sources) unintegrated, whereas example B shows same two information sources, but this time spatialy integrated.

Experiments have confirmed importance of this principle¹⁾
