Effects of Fast Simple Numerical Calculation Training on Neural Systems

Figure 2

Practice-related performance increase in (a) paper-and-pencil tasks and (b) computerized tasks after FSNC training. Both paper-and-pencil and computerized tasks consisted of addition, subtraction, and multiplication tasks. Practice resulted in a significant increase in performance across all training tasks (in paper-and-pencil tasks, performance was measured in terms of the largest number of items answered in one trial; in the computerized tasks, performance was measured in terms of the shortest interstimulus interval (ISI) of blocks in which participants answered correctly in more than half of trials) from the first to the last day of training (one-tailed paired test, ). Error bars represent standard errors.
