工作记忆在简单指数乘法等式判断中的作用

选择大学二年级数学系的学生作为被试，要求他们完成控制条件、语音任务、手动任务和随机间隔决策任务条件下的简单指数乘法等式判断任务，实验结果表明：（1）三种次级任务在真假等式判断的反应时上的干扰效应非常显著；（2）三种次级任务显著增加了假等式判断的错误率，但没有显著增加真等式判断的错误率。这说明，语音环路、视空间模板和反应选择成分参与简单指数乘法等式判断，而且真假等式判断具有不同的注意资源需求。

The Role of Working Memory in the Verification of Simple Monomial Addition Equations

Students chosen from the second-year in the mathematics department of a university as subjects were required to verify simple exponent multiplication equations under four conditions,namely, control, concurrent articulatory suppression, concurrent hand tapping, and concurrent random interval decision. The experiment results showed that: (1) three kinds of concurrent secondary tasks had a significant disruption effect on the verification reaction time of simple algebraic tasks; (2) the secondary tasks significantly increased the error rates of false equations, but not true equations. Theses results suggested that phonological loops, visuo-spatial sketch pads, and components of response selection were involved in the verification of simple exponent multiplication equations, and there were different degrees of attention demanding between the verification of true equations and that of false equations.
