本研究的目的是比较四种测量心算乘法项目难度的方法：瞳孔放大率、解题潜伏期、正确反应数和项目难度判断。16个乘法问题，分为四个难度水平，视觉呈现给13名学生，谁口头表达他们的解决方案的问题。计算方差分析和相关系数。得出的结论是，所有四个措施的难度是有用的，但判断的难度和延迟的解决方案是更好的措施项目难度比其他两个。瞳孔扩张和信息处理的讨论。
The purpose of this study was to compare four measures of difficulty of mental multiplication items: percentage of pupillary dilation, latency of solution, number of correct responses, and judgment of item difficulty. Sixteen multiplication problems, classified into four levels of difficulty, were presented visually to 13 Ss, who verbalized their solutions to the problems. Analyses of variance and correlation coefficients were computed. It was concluded that all four measures of difficulty were useful but that judgment of difficulty and latency of solution were better measures of item difficulty than were the other two. A discussion of pupillary dilation and information processing is included.
