We review the evidence for the conceptual association between arithmetic and space and
quantify the effect size in meta-analyses. We focus on three effects:(a) the operational …

In 1974, Roger Sperry, based on his seminal studies on the split-brain condition, concluded
that math was almost exclusively sustained by the language dominant left hemisphere. The …

While the influence of spatial-numerical associations in number categorization tasks has
been well established, their role in mental arithmetic is less clear. It has been hypothesized …

Behavioural and neurophysiological evidence suggest that vision plays an important role in
the emergence and development of arithmetic abilities. However, how visual deprivation …

Observational studies have shown that interruptions are a frequent occurrence in diagnostic
radiology. The present study used an experimental design in order to quantify the cost of …

Arithmetic operations are complex mental processes rooted in the abstract concept of
numerosity. Despite the significance, the neural architecture responsible for these …

Adults shift their attention to the right or to the left along a spatial continuum when solving
additions and subtractions, respectively. Studies suggest that these shifts not only support …

Numerical Cognition: The Basics provides an understanding of the neural and cognitive
mechanisms that enable us to perceive, process, and memorize numerical information …

Processing numbers induces shifts of spatial attention in probe detection tasks, with small
numbers orienting attention to the left and large numbers to the right side of space. This has …

In Western cultures, small-left and large-right spatial-numerical associations are constantly
found in various simple number processing tasks. It has recently been suggested that spatial …
