Numbers. Those arithmetical values that allow us to analyze and measure our surroundings. Without them, our understanding of the world we live in would be far less interesting. But what may be even more interesting is the way we process those numbers and how closely related that process is to spatial reasoning. The connection between space and numbers, specifically how we materialize values in our heads through mental number lines has been studied over the years, revealing that spatial orientation is incredibly important to this hypothetical number line. One study led by cognitive neuroscientist Stanislas Dehaene investigated how number magnitude is spatially organized in our minds and introduced the phenomenon of Spatial-Numerical Association of Response Codes, or the SNARC effect for short.
