The Validity of Computer-Controlled Magnitude Scaling to Measure Emotional Impact of Stimuli
作者测试了一种计算机控制的量值估计法（一种心理物理学方法，直接在屏幕上操作），并将其与评分量表进行比较，用于测量广告和色情图片的情感影响。通过结构方程模型检验信度和效度，发现量值估计法在信度、收敛效度和区分效度方面表现良好，是评分量表的一个有效且可靠的替代方案。
A computer-controlled facility is tested which operationalizes magnitude scaling (psychophysics) directly over a CRT screen. The author reports experimental findings comparing magnitude scaling with rating scales as attitude measures of advertisements and erotic pictures. Also, validity and reliability are examined by means of the structural equation approach. On the basis of the level of reliability and the degree of convergent/discriminant validity, magnitude scaling appears to be a valid and reliable alternative to rating scales.
