It has long been of interest to philosophers and scientists, with perhaps the biggest historical step towards our modern ideas occurring within Immanuel Kant’sCritique of Pure Reason(1781/1787). Kant argued that space as we know it is a preconscious organizing feature of the human mind, a scaffold upon which we’re able to understand the physical world of objects, extension and motion. In a sense, space to Kant was a window into the world, rather than a thing to be perceived in it.

While philosophers following Kant have debated his theory on space perception, it served to lay the groundwork for the twentieth century empirical investigation into how the mind constructs the space that we experience. A key piece to how this happens was provided in 1948 by American psychologist Edward Tolman.

Tolman’s main interest was studying the behavior of rats in mazes – specifically, he was interested in whether a rat came to understand the layout of an environment through purely behavioral mechanisms, or if there was a cognitive process underlying their navigation ability.
