  7. Working Memory impairments affect differently both suffers of math anxiety (an emotional condition) and dyscalculia (a cognitive condition). The dyscalculia group showed visual-spatial working memory impairment, the math anxiety group showed more impairment in verbal working memory, but also showed impairment in visual-spatial tasks with a high cognitive load (ex. many objects to memorize). This supports that anxiety can use up working memory resources and contribute to poor math performance.

(8-29-12) A new study by researchers at UT Dallas’ Center for Vital Longevity, Duke University, and the University of Michigan has found that the strength of communication between the left and right hemispheres of the brain predicts performance on basic arithmetic problems. The findings shed light on the neural basis of human math abilities and suggest a possible route to aiding those who suffer from dyscalculia– an inability to understand and manipulate numbers.
