People frequently gesture when problem‐solving, particularly on tasks that require spatial
transformation. Gesture often facilitates task performance by interacting with internal mental …

Abacus mental arithmetic involves the skilled acquisition of a set of gestures representing
mathematical algorithms to properly manipulate an imaginary abacus. The present study …

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 …

Freely available software has popularized “mousetracking” to study cognitive processing;
this involves the on-line recording of cursor positions while participants move a computer …

We examined the use of hand gestures while people solved spatial reasoning problem in
which they had to infer motion from static diagrams (mental animation problems). In …

Mathematics requires precise inferences about abstract objects inaccessible to perception.
How is this possible? One proposal is that mathematical reasoning, while concerned with …

In 4 experiments, the authors examined the use of the hands in simple arithmetic tasks.
Experiments 1 and 2 demonstrated that pointing increases both accuracy and speed in …

Gesturing has been shown to relay benefits to speakers and listeners alike. Speakers, for
instance, may be able to reduce their working memory load through gesture. Studies with …

Can action support cognition? Can direct touch support performance? Embodied interaction
involving digital devices is based on the theory of grounded cognition. Embodied interaction …

Recent research on spatial number representations suggests that the number space is not
necessarily horizontally organized and might also be affected by acquired associations …
