| The experimental results show that: concurrent articulatory suppression, concurrent hand tapping and concurrent random interval decision significant impact on the reaction time and the correct rate of the multi-digit mental arithmetic, the phonological loop, visuo-spatial sketch pad are involved in two-digit mental arithmetic and three-digit mental arithmetic. Central Executive system involved in complex mental arithmetic. Math anxiety was high in the various tasks under the conditions of reaction time are significantly higher than low math anxiety, that high anxiety aroused addition of the math anxiety effect. Math anxiety does occupy the complex calculation for the working memory resources, difficult topics (binary number) With the rounding of all the increase in the number of test reaction time increased, the rounding the increase in the number of the need to implement additional steps, thus occupy more of the work of memory used in the calculation of resources, resulting in increased competition and resources reaction. To sum up the phonological loop, central executive system play a more important role in the multi-digit mental arithmetic. Visual spatial sketch pad in the rounding of the large number of cases also involved in the process of rounding. |
