通过阅读能力测试、算术速度测试在300名三年级儿童中选取单独计算困难(n=22)、计算和阅读都困难(n=18)两个实验组和年龄控制组(n=23),使用计算机呈现以数字、图形、汉字三种材料组成的六个快速命名任务,以考察计算困难儿童的抑制控制及转换能力。结果表明:(1)计算困难儿童的抑制控制及转换能力显著低于控制组儿童;(2)单独计算困难儿童只在数字材料任务中的反应成绩显著低于控制组儿童;(3)计算与阅读都困难儿童三种任务材料的反应成绩显著低于控制组儿童。
Through the reading ability test, the arithmetic speed test selected separate calculation difficulties among 300 third grade children (n = 22), both of which were difficult to calculate and read (n = 18) and two age groups (n = 23) The computer presents six rapid naming tasks consisting of three types of figures, graphics and Chinese characters to examine the suppression control and conversion ability of children in difficult-to-calculate situations. The results show that: (1) the control and conversion ability of children in control group is significantly lower than those in control group; (2) the scores of children with difficult-to-calculate children alone in digital material task are significantly lower than those in control group; (3) The response scores of the three task materials for children who are difficult to read were significantly lower than those of the control group.
